4 Summary ATS 4910CR Duct Advantages Summary ATS provides a cleanroom compatible and user friendly duct system featuring unique field joint connection options and a complete line of duct, fittings and accessories in round, rectangular and oval configurations. ATS 4910CR is a Fire Safe duct and can be installed without internal sprinklers in Cleanrooms (per FM 4922 approval) eliminating the need for sprinklers, drains, acid waste neutralization and extra heavy hangers. Longer duct lengths require fewer joints to reduce installation time and costs. Simple and fast installation of U collars & H collars with ChemBond putty provide a 100% seal and do not require sanding in the field. The ATS ISO flange is an improved adaption of the stainless steel FM and KF flanges with over 10,000 successfully installed without a single failure. Branch taps can be added to an operating system without a need for costly shutdown (hot tap) and eliminates the need for installing redundant taps in anticipation of future connections. ATS slip taps can be installed anywhere in a system and have an internal flange for greater corrosion resistance. ATS Cleancoat comes in standard white or gray for protection and aesthetic considerations with other custom colors available. ATS provides no cost on-site training worldwide and offers annual safety inspections. The ATS 4910CR system is warrantied for 3 years when installed in accordance with ATS procedures, guidelines and requirements. Fitting Summary Elbows, Branch Taps & Reducers ELBOWS: ATS provides elbows in round, rectangular and oval shapes. Smooth radius round 90, 60, 45 & 30 elbows are provided with the centerline radius 1 ½ times the diameter (1.5D) in sizes 2 ɸ (50 mm) to 30 ɸ (750 mm). Sizes greater than 30 ɸ (750 mm) diameter, rectangular, oval and round elbows with 1D and special radius elbows are provided in gore segments. Elbows 56 to 90 are available in 2-gores (with turning vanes*), 3-gores and 5- gores. Elbows 35 to 55 are available in 2-gores and 3-gores. Elbows below 35 are only available in 2 gores. Round elbows are provided with straight collars on each end for true degree of angle change and straight connection to the adjoining duct and/or fitting. TURNING VANES: Turning vanes in 2-gore 90 degree elbows are only available in round duct > 14 ɸ and in rectangular elbows with the turning side > 14. BRANCH TAPS: ATS offers branch taps factory bonded or saddle taps for installation at the site. Standard 90 taps are provided as a straight TEE, Shoe TEE and Double Shoe TEE. Lateral taps are standard 45, but we can be provided lateral taps at any angle to the centerline of the duct. ATS HOT TAP is used to make a branch connection on an operating system. By following the written procedures described in the Installation Section of this guide and the ATS Hot Tap video, branch taps for equipment hookup can be installed in minutes without affecting the operating airflow in the header duct, using cleanroom compatible ChemBond putty mix. BRANCH TAPS: ATS offers branch taps factory bonded or saddle taps for installation at the site. Standard 90 taps are provided as a straight TEE, Shoe TEE and Double Shoe TEE. Lateral taps are standard 45, but we can be provided lateral taps at any angle to the centerline of the duct. Summary SADDLE TAPS FOR BONDING AT SITE: For bonding saddle taps on non-operating systems, ATS recommends the ATS SlipTap. This system provides an internal slip tap flanged collar that is prepped with putty mix and is inserted into the installed duct and pulled into position where the slip tap flange meets the interior surface of the duct and the collar protrudes outward of the external duct surface. An outside saddle tap prepped with putty mix slides over the protruding collar, creating a structural bond with a 100% seal of the main duct for ultimate corrosion resistance. 6 ATS Reference Guide 2013 ATS, Inc.

5 Summary Unique ATS Connection Summary ATS H-Collar Universal Connector - Receives Any Straight Duct End In a continuing effort to reduce installation time. ATS invented the H-Collar Joining System. The H-Collar system provides a contiguous internal liner and serves as an alignment tool. There are no external wraps to do! It is only necessary to apply the ATS ChemBond putty and slip the duct into the collar. Literally, this joint can be put together in minutes! ChemBond Resin Summary Cleanroom Safe Low Odor No Sanding Required Superior Chemical Resistance High Structural Strength FM Approved as a Joining System ChemBond offers features important to the cleanroom industry: Summary The ATS H-Collar allows the contractor to modify duct lengths on site without worrying about special preparations of duct ends. Just cut and join! Key Benefits of the H-Collar: Drastically cuts installation time Provides a cleaner and better looking installation Strength: Equal to or greater than the duct itself! Tested for Pressure: Did not leak at 300 psi Most often used for small and medium duct and fittings. ATS U-Collar Universal Connector - Receives Any Straight Duct End Universal Connector - Receives Any Straight Duct End A U-Collar is an H-Collar wound into the duct, leaving only one side left to bond. This cuts contractor bonding time in half. Acceptable Microcontaminant (ng/cm 2 ) Levels Extremely low emission of VOCs during installation NO SANDING High Corrosion Resistance High Strength Bonds Bonds Multiple Materials Ease of Installation ATS ChemBond TM Resin is a unique product with characteristics that simplify the installation of ATS Duct TM. ChemBond TM resin with glass reinforcement can be used to bond two adjoining pieces of ATS Duct TM without pre-sanding the duct surface. Because it has minimal odor, requires no sanding, and has no adverse microcontaminant effect on silicon wafers (whether it is a liquid or solid state), it is especially desirable in sensitive cleanroom environments where dust and odors are prohibited and where microcontamination is a concern. ATS, Inc. has done extensive testing of ChemBond Insuring it meets the needs and standards of the industry. Most often used for large duct and fittings.

6 Summary ATS provides simple, cleanroom compatible and user friendly field joint connections, a variety of branch tap connections and duct work in round, rectangular and oval to suit site conditions. ATS offers a complete line of dampers. Installation Advantages: 1. ATS 4910CR duct can be installed in cleanrooms and without internal sprinkler protection per Factory Mutual 4910 and 4922 Standards, as listed in the FM Approval Guide. 2. The duct can be installed without sanding and without foul odors, using ChemBond Resin and Putty. 3. The ChemBond Resin/Putty can be used in clean environments. 4. Duct and fittings can be provided with the option to have a U-Collar on one end or with flanged ends. 5. Duct is provided in standard lengths of 10-0 (3 meter) and 20-0 (6 meter). 6. Laterals can be installed without redundant tool connection taps. ATS SlipTaps can be installed at exact required locations after the laterals are installed, minimizing system cost. 7. Duct branch taps and fittings can be joined to dissimilar products such as PVC, PP, Stainless Steel and FRP. 8. ATS branch taps can be installed on operating systems without interrupting critical air flow, by using the ATS HOT TAP and installation method. 9. ATS provides MF and KF ISO Flanges primarily used for high pressure vacuum and abatement tool exhaust. Sections of duct and fittings are connected using 100% seal H-Collar joints and ISO flanges are connected on each end of these sections, so the sections can be removed, cleaned and reinstalled for long-term service. 10. ATS provides world class service, training and installer certification. 11. With the installation performed by trained and certified installers, ATS offers a 3 year standard warranty. 12. ATS offers annual site inspections to ensure long-term, satisfactory system performance. Installation Requirements: 1. The duct must be installed in cradle style supports. Installation Summary Product Advantages and Requirements 2. All cut edges must be sealed with ChemBond Resin/Putty to achieve maximum system corrosion resistance. 3. ATS Test Ports must be installed when making port holes in the ductwork for balancing and measurement instruments. 4. Condensate drains must be installed at all low points in the system where liquid can accumulate. 5. Elbows, offsets and taps must be supplied to the site from the factory. Site made fittings will nullify the warranty and may jeopardize the FM approval of the installed system. 6. Ductwork installed outdoors must be painted with CleanCoat, the coating listed in the FM Approval Guide for use on ATS duct for UV protection and for cosmetic purposes indoors. Guidelines for Exterior Coatings Summay IMPORTANT NOTE: It is necessary to coat all exterior ductwork. ATS manufacturers recommendations require exterior duct to be painted with CleanCoat, HaloCoat, or other comparable coatings to provide UV and weather protection for maximum service life (Also see expansion joints for roof top duct.). General Recommendations: 1. When using coatings other than ATS Cleancoat or ATS ChemSeal, check local restrictions on those products regarding VOC content before considering their use. ATS Cleancoat and ChemSeal are 100% solid coatings. 2. Do not use water based intumescent paints. They tend to crack and flake off in time, creating problems in Cleanrooms. On outdoor use, the intumescent salts leach out in time and intumescent paints have poor weather resistance. Cleanroom Coatings: If the product is to be installed in cleanroom areas where low particle counts are required and an owner is particularly concerned with particles eroding off of the duct surface or with contaminants adhering to the duct surface, we recommend ATS CleanCoat. ATS CleanCoat is an odorless interior coating with excellent abrasion resistance, adhesion characteristics, and chemical resistance to vapors and liquid splashes. It can be applied directly to the clean/dry exterior of ATS Duct systems without sanding or scuffing the surface, which makes it an ideal coating inside the cleanroom. ATS Duct, when coated with CleanCoat, retains its FM Approval for installation without sprinklers. Outdoor Coating: For the highest possible performance ATS Cleancoat should be used for applications where there are extreme changes in the weather. ATS Cleancoat is an interior/exterior coating with excellent abrasion resistance, UV resistance, adhesion characteristics, low flame and smoke characteristics, and chemical resistance. CleanCoat is a 100% solids coating that can be applied to the clean, dry exterior surface of ATS Duct without sanding or scuffing the duct surface. CleanCoat is available in 1 and 5 gallon containers in gray, white, or other colors as desired, such as brown. It can be applied to the duct with a brush, roller or it can be sprayed on with a paint gun on outdoor duct or on sections of duct prior to installation in the cleanroom. Note: The color of the exterior coating on outdoor installations will effect the surface temperature of the duct. Light colors will reflect sunlight and keep the duct surface closer to ambient temperatures. Dark colors will absorb solar heat and increase the duct temperature well above ambient. Dark colored ducts will expand and contract at a much greater rate than light colored duct. (See Coefficient of Thermal Expansion Example on Page 171). Summary 10 ATS Reference Guide 2013 ATS, Inc.

The H-Collar system builds on the ATS Internal Beaded Slip Collar s success in providing a contiguous internal liner and as an alignment tool. But the H-Collar takes simplification in joining one step further. There are no external wraps to do! Now it is only necessary to apply the ATS ChemBond putty and slip the duct into the collar. Literally, this joint can be put together in minutes! Important Note Like U COLLAR the ATS Slip Collar, the ATS H-Collar is universal it accepts any straight butt end. This allows the contractor to modify duct lengths on site without worrying about special preparations of duct ends. Just cut and join! Key Benefits of the H-Collar: Drastically cuts installation time Provides a cleaner and better looking installation Dimensional Chart in Inches Diameter Slot Width Bond Length Structural Area Collar Length U-Collars are available on straight duct and fittings (smooth radius or gored elbows, reducers, etc.), as requested by the installer/buyer. Connections are made using the same methods described for the H-Collars, but because the U-Collars are pre-attached to the duct or fitting ends, only one bond connection is required during the bonding process. The U- Collar consists of an internal slip collar, a reservoir channel, setscrews and an external structural collar. There is no structural area to consider when measuring and cutting, however the adjoining duct and fitting ends must fit correctly by sliding over the internal slip collar and into the reservoir channel to ensure a complete seal for ultimate corrosion resistance.

It is not designed as a close-off or isolation damper. However, the amount of leakage through the damper in the closed position is directly proportionate to the gap between the damper blade and the inside surface of the duct. ATS standard VCDs have a leakage rate of 5%. Please specify if your specifications call for a lower leakage rate. Round VCDs are provided with plain ends on sizes 2 ɸ to 20 ɸ (50 mm to 500 mm) and with flanged ends 22 ɸ (550 mm). Rectangular dampers are provided with flanged ends. Mating flanges must be ordered separately. MBD/OBD/ISOD Multi-Blade dampers are available in round and rectangular shapes. Typically the blades are linked so they are operated by one point of control, either a manual control arm, a wheel or a pneumatic or electrical actuator. These dampers can be made with the blades operating in parallel (MBD) with each other or opposed blade (OBD), where the blades turn in opposite directions when operated. They also can be made to operate individually, with each blade having its own control lever. These dampers are commonly made for volume control, however they can be provided with blade seals for isolation. Isolation dampers (ISOD) are generally required on lateral headers at or near the tap connection to the main duct header or in the scrubber and fan area to isolate equipment for maintenance. These dampers are round or rectangular and have blade seals to be as close to 100% leak proof as possible. Round ISODs are usually single blade and rectangular are commonly multi-blade. They are provided with flanged ends and can be gear, chain-fall or motor actuated. BDD/NRD Back-Draft dampers (BDD) are commonly required on fan discharges or between the scrubber and the fans. These dampers are either multi-blade or single blade and are in the open position when the system is operating. They are general controlled by a gravity control arm which automatically closes the damper if the system is shutdown or an isolation damper is closed downstream. BDDs are provided with flanged ends. No Return Dampers (NRD) are safety valves on small diameter ducts close to the process connection which close automatically if the damper at the exhaust POC is closed. BG Blast-Gate dampers are provided in round or rectangular shapes. Large blast gates near fans and scrubbers can be either manually, rack and pinion or gear operated, while smaller blast-gates closer to tools are manually operated. ATS provides 100% seal blast gates if specified and they are provided with flanged ends rectangular duct and on sizes 22 ɸ (550 mm) on round duct.

33 Scrubbers The ATS Crossflow scrubs virtually all inorganic compounds, and maintains stack emissions to specific ppm levels determined by local permit requirements for all input concentrations. Specific outlet requirements based on percent removal can also be guaranteed. Key to the performance of this industrial equipment is high-flow liquid recirculation, which produces intense contact between the contaminant and scrubbing liquid. Horizontal Scrubber OTHER PRODUCT Three industrial system configurations are available. The internal tank/ansi pump design is manufactured in capacities of 50 cfm through 100,000 cfm. An internal Tank/Vertical pump design is available for 50 cfm through 60,000 cfm applications. An External recirculation System/Dry Sump design is available in single or multiple stage options, with a maximum single unit capacity of 120,000 cfm. The ATS Crossflow versions operate with zero production down time, because critical system modules have full redundancy. Back-up readiness is assured through regular auto hand-over from primary systems. This feature significantly reduces both monitoring and maintenance requirements, and assures full operation, even during normal maintenance of the equipment. OTHER PRODUCT Crossflow industrial scrubbers are supplied with control panels and operator interface. Standard material of construction is UV stabilize polypropylene. PVC and stainless steel are optional materials. ATS Crossflow scrubbers use power packing and high-efficiency industrial mist eliminators. Quench equipped systems can accommodate inlet temperatures to 2000 F. Fiberglass Fan Applications: broad range of industrial manufacturing and process industries. Also, semiconductor, metal finishing, and chemical industries and all facilities generatingcorrosive fumes and gases. Fiberglass Fan A scrubber that employs a dry chemical medium includes a first vessel defining a first cavity. A second vessel adjoining the first vessel defines a second cavity, and the first and second cavities combine to form a common chamber. A fan draws a gaseous stream into the chamber at a first location and extracts the gaseous stream from the chamber at a second location. A plurality of partitions extend substantially from the upper end of the chamber to the floor. A dry chemical medium is disposed within the spaces between the partitions for neutralizing a pollutant in a gaseous stream. The partitions have openings of a sufficiently large size to permit gas to flow there through but of a sufficiently small size to prevent the dry chemical medium from passing there through. A method for converting a wet scrubber to a dry scrubber of the type described is also disclosed. 64 ATS Reference Guide 2013 ATS, Inc. All Rights Reserved ATS Reference Guide 2013 ATS, Inc.

36 Custom Contact-Molded Reinforced-Polyester Chemical-Resistant Process Equipment ( This voluntary standard, initiated by the Society of the Plastic Industry, Inc., has developed under the Procedures for the Development of Voluntary Product Standards, published by the Department of Commerce. See section 7, History of Project, for further information.) 1. PURPOSE 1.1. The purpose of the Product Standard is to establish on a national basis the standard size and dimension and significant quality requirements for commercially available glass-fiber-reinforced chemical-resistant process equipment for chemical service. The information contained in this Product Standard will be helpful to producers, distributors, and users and will promote understanding between buyers and sellers. STANDARDS 2. SCOPE 2.1. This Product Standard covers materials, construction and workmanship, physical properties, and methods of testing reinforced-polyester materials for process equipment and auxiliaries intended for use in aggressive chemical environments, including but not limited to pipe, duct, and tanks. The Standard is based on the technology of fabrication by hand lay-out or contact pressure molding. Methods for identifying product which comply with the requirements of this Standard are included This Standard does not cover: (1) resins other than polyesters, (2) reinforced materials other than glass fibers, (3) laminate constructions, or (4) filament wound fabrication methods. (The industry has initiated the development of additional standards to cover these items.) 3. REQUIREMENTS 3.1. General Terminology Unless otherwise indicated, the plastics terminology used in this Standard shall be in accordance with the definition given in American Society for Testing and Materials (ASTM) Designation D883-69, Standard Nomenclature Relating to Plastics General description This Standard describes glass-fiber-reinforced process equipment for chemical service. Other materials may be used for reinforcement of the surface exposed to the chemical environment. The Standard is not intended to cover selection of the exact resin or reinforced combination for use in specific chemical and structural conditions. For recommended chemical resistance test procedures, see the appendix. STANDARDS 3.2. Materials Resin The resin used shall be of a commercial grade and shall either be evaluated as a laminated by test (see appendix for a recommended test) or determined by previous service to be accepted for the environment Fillers and pigments The resins used shall not contain fillers except as required for viscosity control or fire retardant. Up to 5 percent by weight of thixotropic agent which will not interface with visual inspection may be added to the resin for viscosity control. Resins may contain pigments and dyes by agreements between fabricator and purchaser, recognizing that such addition may interfere with visual inspection of laminate quality. Antimony compounds or other fire retardant agents may be added as required for improved fire resistance Reinforcing materials The reinforcing materials shall be a commercial grade of glass fiber having a coupling agent which will provide a suitable bond between the glass reinforcement and the resin. 1 Later issues of the ASTM publications specified in this Product Standard may be used providing the requirements are applicable and consistent with the issue designated.

37 Custom Contact-Molded Reinforced-Polyester Chemical-Resistant Process Equipment 3.2. Materials (continue) 3.2. Materials (continue) Surfacing materials Unless otherwise agreed upon between fabricator and purchaser, material used as reinforcing on the surface exposed to chemical attack shall be a commercial grade chemical-resistant glass having a coupling agent. Note: The use of other ferrous materials such as acrylic and polyester fabrics and asbestos may affect the values obtained for the Barcol hardness of the surface Laminate The laminate shall consist of an inner surface, an interior layer, and exterior layer or laminated body. The compositions specified for he inner surface and interior layer are intended to achieve optimum chemical resistance. 2 This resin-rich surface layer will usually contain less than 20 percent of reinforcing material. A specific limit is not included because of the impracticability of determining this value in the finished product. pipes and tanks regardless of operating conditions. Isolated small spots may as thin as 80 percent of the minimum wall thickness, but in no case more than 1/8 inch below the specified wall thickness Mechanical properties In order to establish proper wall thickness and other design characteristics, the minimum physical properties for any laminate shall be as shown in table 1 and Laminates which do not meet the minimum values of table 1 and considered accepted provided they are made to afford the same overall strength that would be obtained with a laminate meeting the specified thickness. For example, if the specified thickness for a laminate is 1/4 inch, reading from table 1 a minimum tensile strength of 12,000 psi is required. By multiplying thickness times minimum tensile strength a value of 3,000 pound breaking load for a 1 inch-wide specimen is obtained. A laminate having a tensile strength of 10,000 psi will, therefore, be acceptable for the 1/4 inch requirement if it has an actual thickness of at least 0.3 inch Inner surface The inner surface shall be free of cracks and crazing with a smooth finish and with an average of not over 2 pits per square foot, providing the pits are less than 1/8 inch in diameter and not over 1/32 inch deep and are covered with sufficient resin to avoid exposure of inner surface fabric. Some waviness is permissible as long as the surface is smooth and free of pits. Between and inches of reinforced resin-rich surface shall be provided. 2 This surface may be reinforced with glass surfacing mat, synthetic fibers, asbestos, or other material as usage requires Surface hardness The laminate shall have a Barcol hardness of at least 90 percent of the resin manufacturer s minimum specified hardness for the cured resin when tested in accordance with This applies to both interior and exterior surfaces Appearance The finished laminate shall be as free as commercially practicable from visual defects such as foreign inclusions, dry spots, air bubbles, pinholes, pimples, and delamination. STANDARDS Interior layer A minimum of inch of the laminate next to the inner surface shall be reinforced with not less than 20 percent no more than 30 percent by weight of noncontinuous glass strands (see 4.3.1), e.g., having fiber lengths from 0.5 to 2.0 inches Exterior layer The exterior layer or body of the laminate shall be of chemically resistant construction suitable for the service and provided the additional strength necessary to meet the tensile and flexural requirements. Where separated layers such as mat, cloth, or woven roving are used, all layers shall be lapped a minimum of 1 inch. Laps shall be staggered as much as possible. If woven roving or cloth is used, a layer of chopped-strand glass shall be placed as alternate layers. The exterior surface shall be relatively smooth with no exposed fibers or sharp projections. Hand work finish is acceptable, but enough resin shall be present to prevent fiber show When the outer surface is subject to a corrosive environment, the exterior surface shall consist of a chopped-stand glass over which be applied a resin-rich coating as described in Other methods of surface protection may be used as agreed upon between buyer and seller By agreement between buyer and seller, a representative laminate sample may be used for determination of acceptable surface finish and visual defects (see 3.3.1, 3.3.3, and 3.3.8) Reinforced-polyester round and rectangular ducting Duct size and tolerances Round ducting The size of round ducting shall be determined by the inside diameter in the inches.

Although this Installation Guide contains specific information, this information is not to be considered as the only criteria for correct duct work installation. The Owner, Engineer, and/or Installer is responsible for establishing procedures for satisfactory duct system design, protection and performance. Some items which are specifically addressed in this manual, and are extremely important, are required methods for installing Test Port (Instrument Port) connections, making a Hot Tap (branch) connection into the live system, making duct/fitting bonds, duct supports and coating of duct work installed outside of the building. These issues need to be considered prior to the actual expansion or modification to the existing operating duct work. ChemBond is a unique resin/putty system that is used to join ATS 4910CR Duct Systems without the need to pre-sand the duct end surfaces. When using the ATS 4910CR duct system, only ChemBond Resin should be used for bonding. The excellent chemical resistance and superior adhesion characteristics of the ChemBond Resin makes for a simple and practically fool proof joint. Throughout this manual, there is reference made to the importance of sealing raw cut edges in the 4910CR duct. The single most critical step when making a cut, drilling a hole or connecting branch tap into the duct, the raw exposed edges of the duct must be sealed with ChemBond resin mix. It is also important to know that ChemBond Resin/Putty can be used during normal working hours, as it has no off gassing or foul odor issues. However, we recommend pre-mixing the Part A & B resin/putty components prior to entering the clean room environment to simplify the number of materials brought into the clean air space.

43 INSTALLATION ChemBond Resin Mixing and Charts BULK RESIN MIXING INSTRUCTIONS ChemBond TM Resin for exterior of Slip Collar and Slip Collar Flange Joints The ChemBond TM Resin is used to bond the exterior of the joints. It is catalyzed using Standard Hardener. This section addresses the use of ChemBond TM Resin with Hardener. The resin is not used when making H-Collar TM joints. See installation instructions. The ratio of ChemBond TM Hardener is 15% by weight of the Resin (for 100 grams of ChemBond TM Resin use 15 grams of Hardener). Proper ratios of resin and hardener and thorough mixing of the resin are crucial to proper cure, chemical resistance and strength of the joint. Do not Eyeball quantities. Be sure to mix until resin and hardener are mixed together uniformly and then continue to mix for 2-3 minutes more. Refer to the ChemBond Resin Chart below for common size batches. DO NOT ALTER THE RESIN RATIO! 15% BY WEIGHT HARDENER TO RESIN! The curing cycle can only be accelerated by applying heat to the surface of the lay-up. A Hot-air gun works well to expedite the cure.

44 ATS PRODUCTS, INC. H & U - COLLAR INSTALLATION INSTRUCTIONS H-COLLAR (For U-Collars see pages 6 through 8.) Installing ATS duct requires accurate measurement and cutting to insure a proper seal and bond when duct and fittings are connected using ATS H-Collars. The H-Collars consist of an internal slip collar, a reservoir channel, a structural area, setscrews and an external structural collar. The adjoining duct and fitting ends must slide over the internal slip collar and into the reservoir channel to ensure a complete seal for ultimate corrosion resistance. See the H Collar Section below: SETSCREW (TYPICAL) INTERNAL SLIP COLLAR STRUCTURAL AREA BOND LENGTH RESERVOIR CHANNEL "H" COLLAR DIMENSIONAL CHART Dia. Bond Structural Overall Dia.

The Structural Area is 1/2 for all H-Collars, so 1/2 must be subtracted from the duct or fitting to achieve the overall desired length. Also, smooth radius elbows will fit properly into H-Collars, because of the extensions on the elbow ends. Large diameter elbows and special radius elbows are provided as Gored Elbows with extended legs equal to the Bond Length of the H-Collar. When figuring dimensions for fitting gored elbows into the duct assembly, use the following formula: For standard radius elbows the centerline to face is 1-1/2 times the diameter + Bond Length; for short radius elbows the centerline to face is the diameter + Bond Length.

45 PREPARATION: The H-Collar and duct/fitting surfaces must be clean prior to bonding. Cleaning the exterior surface with an isopropyl alcohol wipe will remove most foreign debris. When the surfaces are ready for bonding, wrap 2 wide tape around the end (optional) of the H-Collar and another strip around the duct a distance of the Bond Length, plus ½, back from the end of the duct as shown in the PREPARATION detail below.

Next, apply a thin layer of Putty Mix to the outside surface of the duct/fitting end for the distance of the Bond Length or up to the tape applied to the duct as described in Preparation above. Then apply Putty Mix to the end of the duct/fitting. PUTTY MIX APPLICATION PUTTY DUCT END "H" COLLAR SECTION DUCT SECTION ChemBond Putty Instructions PUTTY INTO CHANNEL INSTALLATION ATS provides pre-measured individual bonding kits for each H-Collar or U-Collar connection. The kits consist of a container of putty for the given diameter and a second container with the amount of hardener required properly cure the putty mixture. The labels are clearly marked to identify the diameter of duct intended for its use. PUTTY INSIDE BOND LENGTH SURFACE 1/16" TO 1/8" THICK APPLY A THIN LAYER OF PUTTY TO OUTSIDE OF DUCT END TO TAPE INSTALLATION MIXING PUTTY AND HARDENER: Begin by transferring the entire amount of Putty Hardener into ChemBond Putty container. Blend the mixture thoroughly for a minimum of 2 minutes, until smooth and even. Blending the mixture thoroughly will yield the required strength and corrosion resistance characteristics of the resin. CONNECT AND FINISH (see detail below, page 5): SLOWLY-Slide the duct/fitting prepared end into the prepared end of the H-Collar, taking care to insert the duct/fitting end evenly into the center of the H-Collar opening. Push the duct/fitting all the way into the H- Collar, until the end slips over the Internal Slip Collar and seats into the Reservoir Channel. Holding the connection firmly, tighten the setscrews (see Setscrew Chart page 5) until they rest snuggly against the duct/fitting wall, keeping the space around the H-Collar even. DO NOT OVER TIGHTEN THE SETSCREWS; they should hold the duct/fitting end tightly in the H-Collar, so the next connection can be made while the Putty Mix cures, without disturbing the connection.

46 Smooth the excess Putty Mix on the outside to form a uniform bevel of resin between the H- Collar and the outside duct/fitting surface. Immediately, peel away the tape on the H-Collar and duct/fitting surface, leaving a quality finished joint. NOTE: The ( optional) tape must be removed before the Putty Mix cures. Where possible reach inside the duct and smooth the Putty Mix evenly into the seam of the Internal Slip Collar and duct/fitting connection. #1-INSERT DUCT END OVER SLIP COLLAR AND SEAT IN CHANNEL CONNECT & FINISHING JOINT U COLLAR U-Collars are available on straight duct and fittings (smooth radius or gored elbows, reducers, etc.), as requested by the installer/buyer. Connections are made using the same methods described for the H-Collars, but because the U-Collars are pre-attached to the duct or fitting ends, only one bond connection is required during the bonding process. The U- Collar consists of an internal slip collar, a reservoir channel, setscrews and an external structural collar. There is no structural area to consider when measuring and cutting, however the adjoining duct and fitting ends must fit correctly by sliding over the internal slip collar and into the reservoir channel to ensure a complete seal for ultimate corrosion resistance.

To immediately cure the freshly made joint, wrap an electric drum heater around the center of the H-collar, set the temperature regulator to 180 F (82 C) and apply heat for approximately 5 minutes. Alternatively, a hot air gun can be used to heat the joint and accelerate the cure. Apply heat to the H-Collar and the duct/fitting end. The heat will transfer evenly into the Putty Mix. When the duct/fitting and H-Collar surfaces are hot to touch, remove the heat and the joint will cure in minutes.

The internal bond consists of an internal beaded slip collar which is puttied into the adjoining duct sections to seal the joint from chemical attack from the inside. The external bond consists of glass layers wetted out with ChemBond resin. For large diameter ducts (36 and over), it is possible to do the joint without the internal beaded slip collar. (Alternatively, the H-Collar can be used.) However, the joint needs to be sealed from the inside using ChemBond putty covered with a layer of synthetic veil and ChemBond Resin to protect the joint against chemical attack. SMOOTH RESIN TO FINISH BOND LEVEL ATS ISO FLANGE SECTION VIEW STEP 3 PLUMB STEP 4 Internal Bond Internal Beaded Slip Collar Assembly: Begin the bonding process by mixing the desired amount of ChemBond Putty with Putty Hardener for the size joint(s) to be bonded. Be sure to use appropriate safety precautions when using the resin. Blocking Cream is recommended along with the use of elbow-length gloves. The Blocking Cream acts as a protective layer of skin. ATS ISO SEAL-RING WITH OVER-PRESSURE RING ASSEMBLY Transfer the desired amount of ChemBond Putty into a small container and add the appropriate amount of Putty Hardener at 12.5% of the weight of the Putty (see the Putty Mixing Chart under Mixing Instructions) for weight and volumetric ratios. Blend the mixture thoroughly for a minimum of 2 minutes until the putty mixture is smooth and even. STEP 5 The pot life of the putty is approximately 45 minutes when kept in a shallow pan. If the resin is mixed in a narrow cylinder, the mixture may overheat. Transfer the batch to a low, flat container to avoid problems and prolong resin usage. INSTALLATION POSITION SEAL RING ASSEMBLY TIGHTEN CLAMPS UNTIL THESE ENDS TOUCH TO SEAL THE ISO JOINT AND TORQUE TO 100 INCH-POUNDS The first step is to apply a thin layer of Putty Mix to the inside surface of each of the ducts to be joined (to the depth of the beaded slip collar). Apply a liberal coat of Putty Mix to one side (and edge) of the outside surface of the beaded slip collar and insert the coated end into the duct/fitting end. Bevel the edge of the putty to form a chemical resistant seal. Apply Putty Mix over the remaining outer surface area of the beaded slip collar and slide the adjoining duct/fitting over the collar until the end hits the bead of the beaded slip collar. Heat can be applied (using a hot air gun) to advance the curing of this internal joint to quicken the curing process. Do not use screws to hold the duct/collar assembly in place. They can cause leaks. Clear plastic pallet wrap/tape works well to hold the parts temporarily until the beaded slip collar/duct assembly cures. Wrap the pallet wrap tightly around the duct and it sticks to itself. INSTALLATION STEP 1: SQUARE ENDS OF CUT ENDS AND MAKE SURE PARTS ARE CLEAN AND DRY. STEP 2: MIX COMPLETE CONTENTS OF HARDENER CONTAINER THOROUGHLY INTO RESIN PART B AND APPLY TO DUCT END AND ISO FLANGE SEAL CHANNEL. STEP 3: INSERT THE DUCT END INTO THE FLANGE AND SEAT COMPLETELY INTO SEAL CHANNEL. BE SURE USE A LEVEL TO MAKE SURE THE CONNECTION IS TRUE AND PLUMB, THEN SMOOTH THE RESIN EVENLY TO FINISH THE CONNECTION AND ALLOW TO CURE. STEP 4: ALIGN SEAL RING ASSEMBLY INTO POSITION TO CONNECT 2 ATS ISO FLANGES. STEP 5: USE STANDARD ISO CLAMPS TO SECURE THE FLANGES. THE SEAL IS COMPLETE WHEN THE ENDS OF THE CLAMPS TOUCH.

48 Internal Bond External Bond: Alternative for large diameter duct On duct sizes 48 Ø (1200mm) or greater, contractors experience difficulties in joining ducts because of the added bulk and weight of larger sizes. We recommend one of the following alternative methods that will increase installation efficiency without compromising the corrosion resistance in those instances where the Slip Collar is eliminated. Apply ChemBond putty mixture into the seam of the joint to create an even surface with the outer duct wall surfaces of the adjoining pieces. This putty application seals the ends of the duct/fittings for a complete chemical resistant barrier. INSTALLATION Method #1: To align duct, obtain (from your sheet metal shop) metal sleeves 30cm (12 ) wide (See Figure 2). Ideally, the sleeves should be 12 to 18 gauge rolled in two half-sections and flanged when more than a few joints will be made. The sleeves wrap around the duct joint and tighten snugly with welders clasps. Single piece band sleeves can also be used when only a few joints will be made for a specific diameter. The single piece sleeves should be made a few inches longer than the duct circumference and tightened with draw bands. Each sleeve should have 4 (100mm) square cutouts located every 2 (50mm) along the sleeve centerline as shown in Figure 2. Also obtain 1 x 3 (25mm x 75mm) 18 gauge stainless steel clips with 3/16 (5mm) holes pre-drilled 1/2 (13mm) in from each end and 3/16 (5mm) stainless steel rivets not to exceed 3/8 (10mm) long when installed. Without attaching the slip collar, butt the two ends of the ducts to be bonded together and wrap the 12 (3cm) wide metal sleeve around the joint. Locate the seam of the joint in the center of the 4 (10cm) wide cutouts using clamps or draw bands (or similar means) and tighten the sleeve securely against the seam to temporarily align and hold the sections in position. Flange Place a stainless steel 1 x 3 (25mm x 75mm) clip evenly across the joint in the center of each 4 (100mm) cutout. Drill pilot holes in the FRP duct and attach the stainless steel clip with stainless steel rivet. When all of the clips are installed, the band may be removed. Figure 2 Method #2: Instead of a typical straight duct, a bell and spigot end design can be used. The two adjoining duct sections are slid together. Sheet metal screws can be used to hold the duct together while doing an internal & external joint (detailed in the next section). From the inside, the sheet metal screws need to be cut off and then sealed with ChemBond Putty. Both Methods: The inside of the joint needs to be sealed by having someone go inside the duct and putty the joint seam. Refer to the ChemBond Resin per joint Chart enclosed for the corresponding amount of putty to be used to seal the inside of the joint. It is very important that the seam between the ducts and the stainless steel rivet holes are liberally covered with ChemBond Putty. Once the inside of the joint has been sealed you can proceed with the standard installation instructions for the exterior. External Bond Figure 3 Outside Glass & Resin Lay-Up Bond: Use only boat cloth (fine mesh) for glass reinforcement. The ChemBond Joint Chart lists our recommended glass widths and number of layers. Using a three inch paint roller with 3mm (1/8 nap), wet out the outer surfaces of the adjoining pieces of duct with the ChemBond Resin. This layer should be resin rich, but not so rich as to cause excessive runs and drips. Because of the resin s high viscosity, a liberal amount of resin can be applied easily. Note: It is imperative that the duct be free from oils, dust and moisture to insure good adhesion. In places where the differential between day and night temperatures is great, condensation may affect the viability of an unsanded joint. While ATS joints normally do not need to be sanded, if there is any doubt as to the joint being clean and dry throughout the curing time, a light hand sanding is recommended. Apply one layer of (dry) boat cloth around the wet out joint, pulling the cloth into the joint. Using a squeegee ( a squeegee is preferable to a paint roller, although a paint roller can be used a squeegee is faster, cheaper and it can be cleaned ), wet out the outer surface of the boat cloth smoothing the joint to achieve a resin rich, uniform surface. Refer to the Resin per Joint Chart on page 152 for the sequence, width and total number of glass layers to be applied per joint using the method previously described. External Bond Large Diameter Ducts Another method that greatly reduces the labor charge on large diameter joints is to cut the glass boat cloth in lengths that are a few inches over 1/2 the joint circumference. Wet out the center strip of the smooth waxy side of a butcher paper with ChemBond Resin mix, slightly wider than the width of the glass. Place one of the pre -cut lengths of boat cloth over the wet out area and wet this layer with ChemBond Resin mix. Use a squeegee to evenly saturate the boat cloth. Apply the second layer of cloth over the first layer and wet out with resin as done on the first layer. Proceed with each layer of cloth until the final layer is saturated. Fold the ends of the butcher paper over the ends of the prepared lay up and pick up the butcher paper lay up by the ends. Place one end on the top of the duct joint with the prepared boat cloth centered over the joint seam. Apply the lay up to the joint down the side, pressing against the butcher paper and forcing the lay up into the joint as you move down and around the bottom end. Remove the butcher paper and smooth the layup into position with a squeegee, working from the center to the top and the bottom of the duct. Repeat the process for the opposite side of the joint, making sure to overlap the layup on the top and bottom to make the layup complete.

Begin by mixing Part B Hardener into Part A Putty. Be sure to mix thoroughly for 1 to 2 minutes. Slip Tap HEX Nut 1. Place the pattern into the desired position and mark the cut line on the duct around the outside perimeter of the pattern. Then cut the main duct along the cut mark and remove the cut-out plate. Place saddle tap against main duct at the exact location where it will be installed. Mark the centerline of the tap on the duct for alignment. Using a marker (wax pencil or china marker) inscribe the inside diameter and outside of the saddle flange. Using a jigsaw with a carbide tip or carborundum blade, cut approximately 8mm (3/8 ) outside of the tap diameter line drawn on the duct. This creates a hole for the tap which is slightly larger than the interior of the tap allowing a lip for the ChemBond putty to fill, sealing the cut edge of the main duct. ATS Saddle Taps come pre-sanded on the interior from the factory. Apply ChemBond putty to the underside of the saddle. The putty should be about 3mm (1/8 ) thick. Also apply putty mix to the cut edge of the main header duct. The tap is then placed on the main duct using the saddle centerline marks drawn previously. Stainless steel hose clamps should be used to secure the tap to the main until the putty has cured. As the hose clamps are lightly tightened, putty will ooze out from under the saddle, both on the inside and outside seams. On 3 diameter (75mm diameter) and greater, the inside of the joint can be beveled by hand. By hand, reaching inside the tap, smooth the putty on the interior to create a beveled surface. 3. Apply putty mix to the top of the collar flange face. 4. Slide the puttied collar into the duct with the flange face cut sides entering through the cut-out notches. 5. Pull the slip collar up through the duct, so the bolts are aligned in the center of the notches and the puttied flange face presses into the inner duct surface. The stainless steel hose clamps should be left on the duct for shear strength while the ChemBond putty is curing. *Note: Hose clamps are not supplied by ATS. If stainless steel hose clamps are left on, no further work needs to be done. However, if it is desirable to remove the hose clamps, an additional outside layup is recommended if the duct is 14 greater (due to the weight of the taps). INSTALLATION 6. Apply putty mix to the underside surface of the Slip tap saddle and on the inside of the slip tap to the depth of the slip collar penetrating the duct. (If doing outside lay ups, apply boat cloth to a resin-rich saddle and main duct surface. Use the chart below to determine correct number of layers and glass width. Sanding of the exterior of the Saddle Tap and the main is required for diameters greater than 40 (1000mm) diameter to ensure good adhesion. Use the Saddle Tap Glass Chart below as a guide.) Saddle Tap Glass Chart Only necessary if removing the hose clamps) INSTALLATION 7. Position the slip saddle tap so the holes in the saddle line up with the bolts penetrating the duct through the notches. 8. Press the saddle tap into position on the duct with the bolts penetrating through the holes in the saddle. Place the hex nuts onto the bolts and tighten saddle securely to the main duct.

Note: This operation requires a blast gate (or damper) installed in the tap. Be sure to observe the required cleanroom protocol for cleanliness before performing the following procedure. The immediate area of the live tap operation may have to be temporarily closed off with plastic to contain stray particles. INSTALLATION 1. Dry fit the tap into position to ensure proper fit and alignment of the holes in the tap collar and the holes in the main. 3. Apply ChemBond putty mix to the underside of the saddle tap. Smooth ChemBond Putty Mix to Seal Joint ChemBond Putty Mix 2. Apply ChemBond putty mix to the top of the main duct where the saddle will connect. 4. Insert VE Bolts and tighten the nuts until. Be sure the have a crossing pattern, as in tightening bolts on a flange, so the tap is pressed against the main with even pressure. Smooth out the excess putty to finish the joint. For this operation, two or more workers are recommended. Begin by locating the position of the tap on to the main duct. Place the tap into position. With a china marker or soap stone, mark the main duct along the inside diameter and the outside of the saddle flange. Also, put two hash marks on the tap and the main to mark the centerline for later alignment. This is important, because there will be no other way of positioning the taps in the exact spot once the hole is cut. With 2nd man vacuuming, drill a 3/8 (10mm) hole on the outside edge of the inside diameter of the tap at the upstream end of the cut-out plate. Drill a 6mm hole near the upstream end of the cut-out plate and insert an eye screw. With the saber saw using a Carborundum or Carbide Tip blade (vacuum operating), place the blade in the 3/8 (10mm) hole and begin cutting around the outside of the inside diameter of the tap. Cut away 3/8 (10mm) extra material around the outside of the inner tap diameter marking until the cut-away plate (to be removed) begins to move easily as the perimeter cut nears completion. At this point slide a sheet metal plate over the cut area close to the Eye Screw. Hold the eye screw firmly to not allow the plate to fall into the air stream when the cut is complete. A cord can be attached to the Eye Screw to prevent the plate from falling into the duct.

51 INSTALLATION When the cutting is complete, pull the plate out and away as you slide the sheet metal completely over the hole. Temporarily secure the sheet metal plate to the duct exterior with clean room tape. The inside of the cutout plate may have been exposed to hazardous chemicals and must be decontaminated before it is disposed of. Place 6 mil clear plastic wrap over tap opening and tape securely. Apply ChemBond putty mix to the underside of the saddle tap, spreading the putty evenly a layer about 1/8 (3mm) thick. Pull away the tape securing the sheet metal cover plate and slide the cover along the centerline of the main duct to the edge of the tap hole. Place the back end of the saddle flange against the main duct and align it with the saddle flange outline previously drawn. As you drop the tap toward the main duct to secure it into position, slide the cover plate out. At the moment the cover plate is removed, force the tap into its set position and hold it firmly until the draw bands are tightened to secure the tap firmly against the main header. (Note that ATS Saddle Taps come standard with draw band guide spacers, which prevent the draw bands from sliding during tightening). NOTE: As the saddle flange is pressed against the header duct with the draw bands, putty will ooze out around the saddle flange perimeter on the inside and outside of the tap. This excess putty can be used to seal the inside seam and protect the cut edge and exterior surface of the header duct from chemical attack. See next step below. Lower tap as cover plate is removed Figure 7 Remove Temporary cover plate Figure 8 Make sure that you have donned appropriate chemically-resistant gloves and gear. Slit the plastic covering the branch opening and insert your gloved hand into the end of the tap, lifting the slide of the blast gate. Reach in and spread the putty that has oozed inside firmly into the seam between the saddle and the cut edge of the header duct. Smooth the putty all around to form a beveled transition along the seam to provide maximum chemical protection. As you pull your gloved hand out of the tap, slide the gate closed to block the introduction of air into the operating system so as not to disturb the air balance. Remove the plastic from the end of the tap. With a squeegee or gloved finger, bevel the excess putty mix on the outside perimeter of the saddle flange to create a smooth seam. Continue with the exterior bond, as previously described (for SaddleTaps 14 and greater). ATS Slip Collar Flange ChemBond putty is applied to the slip collar portion of the ATS Slip Collar Flange. Apply a layer approximately 1/8 (3mm) thick. Insert slip collar flange into the duct. The putty will ooze around the outside of the slip collar flange and it will also squeeze out from under the slip collar on the inside. Smooth the putty on the interior to create a beveled surface. On the inside and outside of the joint, the ChemBond putty should be beveled by hand. All slip collar flanges must have an exterior glass and resin lay-up to ensure sheer and tensile strength.

52 Riser Installation Proper installation techniques for ATS Duct on risers is outlined below. The purpose of this detailed instruction is to eliminate the problems caused by condensate dripping down the inside wall of the duct. Prior to final assembly of the riser section, the H-Collar (or Slip Collar) should be bonded into the lower end of each duct. As seen in the blow-up section below, the edge at which the H-Collar meets the wall on the inside of the duct should be smeared with putty and chamfered (smoothed or rounded out) to form an impermeable barrier between the collar and the inside of the duct. This way, any condensate dripping down the wall of the duct will flow over the joining point between the H-Collar and the duct (rather than work its way in between the H-Collar and the duct). In addition, pre-joining the downstream side of the H-Collar will facilitate the final assembly of the riser. ChemBond Joint Chart H-Collar Bevel & Smooth putty mix all around prior to joining the connecting fitting into the lower half of the H-Collar. First install the H-Collar (or Beaded Slip Collar) on the lower end of each piece of riser duct prior to assembling the complete riser section.

53 Cure Times for ChemBond Resin The ATS ChemBond Resin combines superior chemical resistance and high structural strength with low flame and smoke characteristics. The ChemBond resin with glass reinforcement is used to bond two adjoining pieces of ATS Duct without pre-sanding the duct surface. This system is especially desirable in sensitive clean room environments where dust and odors are prohibited. Preparation of All Cut Edges ATS recommends resin coating the edges of all duct and fittings prior to installation when hooking up to wet-etch tools. Resin coating the raw cut edges of the duct will give added corrosion resistance protection to the field joint, especially to Hot Sulfuric Acid and related aggressive oxidizing reagents. The illustration of coating the edges below: Unlike other resin systems, the ChemBond resin cure time is not dependent upon the ratio of hardener. The resin must be mixed in the proper ratio no matter what the temperature. To affect the cure time, the temperature of the resin needs to be adjusted. To shorten cure time the resin should be heated, and to lengthen cure time the resin should be cooled. TAP CUT EDGE RESIN COATED CUT EDGE The ChemBond resin is designed to cure optimally at 75 o F (24 o C). At this temperature, the pot life of a batch of resin is approximately 45 minutes. The resin will cure at lower temperatures, down to 40 o F (4 o C). However, do not allow the resin to freeze. Resin that has frozen is no longer usable. Several different methods of controlling resin cure rates are available. 1. The container of resin can be placed in a water bath to either warm or cool to a desired temperature decreasing or increasing the cure time accordingly. Ensure the water does not come in contact with the resin. 2. A heat gun can be used to warm the area that will be bonded decreasing cure time. The chart below can be used as a guide to resin cure times at various temperatures. The times may vary dependent upon field conditions. RAW CUT EDGE DUCT/FITTING RESIN COATED DUCT EDGE DUCT/FITTING Cure Time For ChemBond Resin Based On Temperature Resin Coating Steps INSTALLATION Time In Hours IMPORTANT NOTE: For the purposes of coating the cut edges of the duct you will use Chem- Bond Resin with Resin Hardener at a ratio of 15% Hardener to the weight of the resin. 1. Mix a small batch of ChemBond Resin and Resin Hardener to the ratios in the note above. 2. Using a brush or roller, apply resin mix to the cut edges of the duct or fitting. 3. Be sure to cover the edges thoroughly. Be sure all raw glass and dry fibers are covered. (Alternatively, Dow Derakane 510A Vinyl Ester Resin can be used.) Please contact ATS Engineering department with questions regarding resin coating duct edges.

54 ATS Test/Inspection Port Assembly ATS Part Type #460 The ATS Test Port Assembly should be used whenever a contractor is required to drill holes in the duct. This assembly provides protection to the duct wall, while allowing the hole to be accessed in the future. Typically, this is necessary for air balancing, an inspection port for video probes or for an instrument connection. This process seals the raw exposed edges of the duct wall resulting from the drilling operation. Step 3: (ATS Test/Inspection Port Assembly, continued) Use ChemBond Putty Mix to coat the threaded duct edge and then liberally coat the exterior threads of the Male Adapter. The test port assembly consists of a Male/Female threaded adapter. The following steps must be followed to ensure a 100% seal of the tap connection. Step 1: Using a Hole Saw, bore a hole equivalent to the I.D. of the threads on the male adapter. A HEPA vacuum is used to remove particulates generated by the drilling process. Step 4: Screw the Test Port Assembly in place until threads are no longer exposed. The excess ChemBond Putty on the outside threads should be smoothed to finish the tap connection. INSTALLATION Step 2a: Step 2b: Use a Standard NPT (National Pipe Thread) Metal Threaded Nipple to tap the hole and form threads into the FRP. This will avoid stripping the PVC threads and insure a secure bond. If an existing Test Port Assembly is not installed properly, remove the whole assembly and install the next larger size Test Port Assembly. Use a Standard NPT (National Pipe Thread) Drill/Tap to match the treads of the new Male Adapter. Drill ing the hole and tapping the threads are performed in one operation. The Inside seam of the Threaded Adapter penetrating the inner corrosion barrier will have a seal completely around of ChemBond Putty Mix. This seal will keep chemicals from leaching through and into the duct wall. INSTALLATION Test Port Installation Test Port Installation 106 ATS Reference Guide 2013 ATS, Inc.

55 ATS Drain Tap Assembly Installation Guide Guidelines for Hanging ATS Duct Step 1: Step 2: Using a Hole Saw, bore a hole equivalent to the I.D. of the threads on the ATS Drain Tap Assembly. Use a Standard NPT Metal Threaded Nipple (not shown) to tap the hole and form threads into the FRP. This will avoid stripping the PVC threads and insure a secure bond. Step 3: Use ChemBond Putty Mix to coat the exposed edge of the hole and then liberally coat the threads of the male adapter. Most duct supports generate some type of stress concentrations, which may cause localized micro-cracking, localized crazing, or other types of defects. For exterior duct, in addition to dead loads, both seismic and wind loads may be imposed on the duct system. Other specialized loads may also affect the design of the duct and its support system such as thermal expansion or contraction, loads from equipment suspended from the duct, large valves, and other unique loads that may be imposed on the duct and the duct support systems. The support systems for ducting may provide restraint in any one of three directions against both displacement and/or rotation. Careful consideration must be given when restraining duct to avoid the development of excessive internal duct stresses such as possible expansion or contraction due to temperature variations. The duct support systems should eliminate or minimize the development of such internal duct stresses by choosing appropriate degrees of restraint. The type of hanger should be specified by the design engineer for your facility. However, in all cases, there must be a minimum of 180 degree saddle support on the bottom half of the duct. The duct should never be allowed to be supported on flat surfaces, such as in the diagram below: Step 4: Screw the Drain Tap Assembly in place until threads are no longer exposed. ChemBond Putty should be applied around the outside edge of the ATS Drain Tap Assembly to complete the connection. Never allow the duct to rest directly on Uni-strut or any other narrow flat surface. (The duct tends to warp over time if it is only supported on one small point.) INSTALLATION Caution! On existing systems that may contain hazardous materials and condensate, use extreme caution and proper safety gear to protect the person drilling holes. Some systems have contained up to 500 gallons of liquid acid! Provisions should be made when drilling holes. Be prepared with a crew with protective gear and a means to deal with condensate. NOTE: DO NOT OVERTIGHTEN SUPPORT BANDS, STRAPS OR U-BOLTS THAT MAY CRUSH OR BIND THE DUCTWORK. The following types of supprt styles are recommended for supporting ATS duct work: INSTALLATION Types A, B, C, E1, I, J & K, shown in the following details all support the duct on the bottom 180 o surface of the duct. Following the support type details are the tables for support spans and band/strap widths. Installation Instructions Drain Tap Installation 108 ATS Reference Guide 2013 ATS, Inc.
