3 GENERAL CONSTRUCTION NOTES 1. These instructions cover typical product application, fabrication, installation and standard conditions and are general in nature. They provide useful guidelines, but the final drawings may include additional details specific to this project. Any conflict or discrepancies must be clarified prior to execution. 2. Materials stored at the job site must be kept in a safe place protected from possible damage by other trades. Stack with adequate separation so materials will not rub together, and store off the ground. Cardboard or paper wrapped materials must be kept dry. Check arriving materials for quantity and keep record of where various materials are stored. 3. All field welding must be done in accordance with AISC guidelines. All aluminum and glass should be shielded from field welding to avoid damage from weld splatter. Results will be unsightly and may be structurally unsound. Advise general contractor and other trades accordingly. 4. Coordinate protection of installed work with general contractor and/or other trades. 5. Coordinate sequence of other trades which affect framing installation with the general contractor (e.g. fire proofing, back up walls, partitions, ceilings, mechanical ducts, HVAC, etc.). 6. General contractor should furnish and guarantee bench marks, offset lines and opening dimensions. These items should be checked for accuracy before proceeding with erection. Make certain that all adjacent substrate construction is in accordance with the contract documents and/or approved shop drawings. If not, notify the general contractor in writing before proceeding with installation because this could constitute acceptance of adjacent substrate construction by others. 7. Isolate all aluminum to be placed directly in contact with masonry or other incompatible materials with a heavy coat of zinc chromate or bituminous paint. 8. Sealant selection is the responsibility of the erector, installer and/or glazing contractor and must be approved by the sealant manufacturer with regard to application and compatibility for its intended use. All sealants must be used in strict accordance with the manufacturer s instructions and applied only by trained personnel to surfaces that have been properly prepared. 9. Sealant must be compatible with all materials with which they have contact, including other sealant surfaces. Consult sealant manufacturer for recommendations relative to shelf life, compatibility, cleaning of substrate, priming, tooling adhesion, etc. 10. Drainage gutters and weep holes must be kept clean at all times. Tubelite will not accept responsibility for improper drainage as a result of clogged gutters and weep holes. 11. This product requires clearances at head, sill and jambs to allow for thermal expansion and contraction. Refer to final distribution drawings for joint sizes. Joints smaller than ¼ may be subject to failure. Consult your sealant supplier. 12. All materials are to be installed plumb, level and true with regard to established bench marks and column center lines established by the general contractor and checked by the erector, installer and/or glazing contractor. 13. Cleaning of exposed aluminum surfaces should be done per AAMA recommendations. 14. Due to varying perimeter conditions and job performance requirements, anchor fasteners are not specified in these instructions. For anchor fastening, refer to the shop drawings or consult the fastener supplier. 15. Check tubeliteinc.com for any updates on installation instructions.

9 Step 1: Determine Frame Size Determine Width Check that the opening is square and plumb at both ends. Units must be installed in a true rectangle. FRAME FABRICATION Measure the width of the opening at the top, middle and bottom. Select the smallest dimension measured. To determine the frame width to be used, subtract a minimum of 1 from the smallest measured width, to allow a minimum of 1/2 at each jamb for shimming and caulking. Allow a larger clearance if necessary to accommodate building tolerances, an out-of-square opening, anticipated thermal expansion within the unit and/or as required by shop drawings. 1/2" min. 1/2" min. Revised June 2016 dependable@tubeliteinc.com Page 9

10 Determine Height Measure the height of the opening in several places along the entire length of the opening. To determine the frame height to be used, select the smallest dimension measured and subtract 1 to allow a minimum of 1/2 at sill and head for shimming and caulking. Allow a larger clearance if necessary to accommodate building tolerances, an out-of-square opening, anticipated thermal expansion within the unit and/or as required by shop drawings. 1/2" min. 1/2" min. Step 2: Cut Mullions to Size Verticals should be frame height found in Step #1 (rough opening height minus clearances). Vertical framing members run through. Cut horizontal framing members to the daylight opening (the distance between verticals) minus 1/16". Revised June 2016 dependable@tubeliteinc.com Page 10

11 Step 3: Drill Holes in Vertical Framing Members For screw spline assembly, fasteners are driven directly through holes in the vertical members into holes in the horizontal members. Drill.228" diameter holes in the vertical framing members using a drill fixture (P2073) as shown below. Match drill.149" diameter holes in the open back perimeter members to attach them to the head/sill shear clip. 1" 1" 2" + 9/32" DLO + 7/16" 2 1/16" DLO + 7/16" Revised June 2016 dependable@tubeliteinc.com Page 11

12 Step 4: Fasten Splice Sleeves in Lower Segments of Verticals Consult the approved shop drawings to see if splices are necessary and what size fasteners to use when fastening splice sleeves to the lower segments of the female and male mullions. Slide a splice backer into the end of the female mullion and a splice bar into the male mullion as shown in Figure 1. The splice backer is 6" long, and the splice bar is 8" long. Half their lengths should be inside the mullion, and half should project out the end of the mullion. For an open back jamb condition, see Page 13. When assembled, fully seal expansion joint using structural sealant. Male mullion Female mullion Backer rod Splice backer Splice bar 1/2" Fasteners (not by Tubelite) 1/2" Figure 1: Splice vertical mullions as necessary.

14 Step 5: Cut Pressure Plates, Face Covers and Snap-in Fillers to Length For vertical pressure plates and face covers not needing to be spliced, cut them to the same length as the corresponding vertical's (rough opening height minus 1/2") clearance at both top and bottom. If necessary to splice vertical pressure plates and face covers, allow a 3/8" gap for the splice joints. The splice in a vertical pressure plate should be 2" below the splice in the mullion, and the splice in a vertical face cover should be 2" below the splice in the pressure plate as shown below. Cut horizontal pressure plates to a minimum of the daylight opening minus 3/16" clearance at each end, or 3/8" less than the distance between verticals, and a maximum of DLO minus 1/16" clearance at each end. Cut horizontal face covers, horizontal glazing adapters and snap-in fillers for roll-over horizontals, to the same length as the corresponding horizontals (daylight opening).
