Each unit consists of the following components. Sub-base - optional, used to support unit on thin wall applications or decorative effect, or to raise unit to provide piping or wiring space. Outside Louver Frame - optional, used on any installation as caulking flange or decorative flange on existing buildings to conceal chipped masonry. Telescopes over cabinet or sleeve extension. Cabinet Sleeve extension - optional, used on thick wall installations. Cabinet Sleeve with Louver - installs through-the-wall to provide a cabinet enclosure for unit chassis. Outdoor louver is installed on cabinet sleeve or optional cabinet sleeve extension. Electrical connection box unfused or optional fused connection box installs in cabinet sleeve with two screws. Front Panel Unit front panel: standard flat top Heating, electric is contained within unit chassis. Hot water or steam is field installed in cabinet. Cabinet sleeve - keep cabinet sleeve in shipping crate until ready for use. Make sure it covers cabinet front as well SEE FIG. 8 OF SUB BASE INSTRUCTIONS FOR FLOOR TO WALL OPENING DIMENSIONS. Figure 1 SEE TABLE II FOR WALL OPENING DIMENSIONS

3 Room Cabinet Wall Sleeve Installation A - Panel and Thin Wall Applications The room cabinet wall sleeve can be installed in various ways. Curtain walls lack sufficient cross-section to securely support the unit. The optional sub-base or similar floor support can be field fabricated to support the unit. See Table II for wall opening guide size. This instruction is based on the use of a sub-base with or without louver frame. both are optional. 1. Remove cabinet from shipping crate. Check cabinet for square and re-square as necessary. 2. Remove sub-base from shipping carton and install as described in sub-base instructions. 3. If louver frame is used, install as shown in frame instructions or per plans and specs. 4. Position cabinet into wall opening. Cabinet rear face maybe recessed up to 2" when optionai louver frame is used. Normally, outside edge of louver would be flush with outside of wall or louver frame when used. Cabinet may be installed to project outside of wall up to a maximum of 4-7/8". See Step 6 as it may be necessary to predrili cabinet holes on nght hand side. Check for proper electrical and/ or piping penetration of sleeve. 5. Level cabinet/wall sleeve and sub base with leveling bolts provided in sub-base. Check each side to level cabinet left to right, and front to back, using top of cabinet. NEVER PITCH TO INSIDE - Level to slight pitch to outside. 6. Secure cabinet to wall by drilling two holes in each side of cabinet (2" from top and bottom) and anchor with lag bolts or fasteners. (See Figure 3). Check final plans and specifications as curtain walls may require a case flange (by others) on inside wall or an alternate method to secure cabinet to wall. 7. Caulk exterior joint on all four sides between cabinet and panel wall or louver frame if used. (See Figure 3). Do NOT permit caulking to block weep holes at bottom rear of cabinet. 8. Cut shipping carton as necessary to cover the installed cabinet until ready for use. Allow 6" for front panel. B - Masonry and Thick Wall Applications Cabinet may be installed in a masonry wall or in brick veneer walls. The size of wall opening will be dependent on use of optional wall sleeve extension, and louver frame. TABLE ll Wall Opening Guide Cabinet only /4 x 16 1 /4 With sleeve extension /16 x 16 1 /2 With louver frame /16 x 16 3 /4 Check final plans and specifications for size which may vary with type of construction. 1. The wall sleeve cabinet may be floor-mounted with or without sub-base, or wall-mounted above the floor. Consideration for electrical and hot water/steam heating must be given in each type of mounting. A lintel must be used to support any brick or masonry work above the cabinet. 2. Remove cabinet from shipping crate. 3. Thick walls may require wall sleeve extension. See extension assembly instructions. 4. Sub-base - when used install as described in sub-base instructions. 5. When optional louver frame is used it must be installed prior to or at same time as sleeve assembly. See louver frame installation instructions. 6. Set room cabinet/wall sleeve assembly on soft mortar and position in wall opening (all-masonry walls). Cabinet rear face may be recessed up to 2" when optional louver frame is used. Normally, outside edge of louver would be flush with outside of wall or louver frame when used. Center of gravity of the conditioner is 9" from rear face of cabinet. For wall mounted units, center of gravity must be within the load bearing portion of the wall. 7. Level room cabinet/wall sleeve assembly. When subbase is used, leveling bolts are provided in sub-base. Check each side to level cabinet left to right and front to back or a slight pitch to the outside. Use top of cabinet for leveling. Securely fasten room cabinet in wall by drilling two holes in each side of cabinet and anchor with lag bolts or fasteners. (See Figure 3.) NEVER pitch to inside. 8. Mortar and caulk as required between cabinet and wall opening (or louver frame) on sides, top and bottom. Do not permit caulking to block weep holes. Recaulk seam between cabinet and extension as required. 9. Cut shipping carton as necessary to cover the installed cabinet until ready for use. Allow 6" for front panel. EXISTING BUILDINGS - For existing masonry construction wall, openings must be made. A lintel should be used to support masonry above cabinet. The cabinet must be anchored to the wall. Shims and fiberglass to stuff wall cavities - top and both sides -should be considered. The bot-

4 tom of the opening must be covered with a layer of mortar and adhesive to form a water and air tight seal. Generally, follow instructions for masonry and thick wall applications. 10. Room cabinet sleeve has a protective film wrap on sides and top. This film is to be removed after construction and all finishing. Score film at finished wall line and peel off. Hot Water or Steam Heat Units which are ordered with steam or hot water coils - field installation of coil, valves, and piping are made within cabinet as shown in Piping Instructions. Rough in of piping must be made before the cabinet sleeve is installed or per plans and specifications. NOTE - Make sure all internal cabinet seals are in place and sealed to cabinet surface on completion of cabinet installation. 1. See figure 2 for wiring entering wall sleeve knockout location. 2. Connect metallic power cable to proper knockout in rear face of box or in base of cabinet within box area. Knockouts outside of box location are for cable passage. The metallic cable is used as a ground to the box. If metallic cable is larger than the 7/8 dia. holes, the passage of cable will be through a field enlarged knockout or the local code approved use of the rectangular hole or knockout in the base of cabinet. 3 Standard box - connect power wires to the RED and BLUE receptacle leads. See Figure 5. Auxiliary Voltage Box - Connect per standard box, main power to L.H. receptacle, auxiliary power to R.H. receptacle. Fused Box - connect incoming power to fuse holder connection, use wire nuts supplied. 4. Secure box to base of sleeve with screws. Base of sleeve forms bottom of box. Flange of electrical box is to be placed under flange of hole cover plate. 5. Auxiliary Power - when auxiliary power is used, red wire is to the left hand side receptacle in knockout of box. The incoming power lines are connected to the leads of the auxiliary power plug. The green wire is connected to the ground screw. Rough in of electrical power supply must be made before the cabinet sleeve is installed. Also electrical contractor must advise cabinet installers of use of knockouts for sleeve installation.

8 Hot Water or Steam Heat Instructions Units which are ordered with steam or hot water coils - Field installation of coil, valves, and piping are made within cabinet as shown in Figure 8. Piping may be recessed in wall or floor for floor mounted units. Units with sub-base will provide concealment to the underside of cabinet. Method should be checked on final plans before installation of cabinet. Pre-piping in sub-base area may be necessary. Coil mounting and piping is shown in Figures 8 and 9 NOTE: Piping must be no lower than 1-7/l6" from top of cabinet forward of piping compartment as shown in Figure 8. Electrical control box of chassis must pass under piping with clearance. Electrical control box must also pass over piping in forward section of sleeve. When this area is used the piping should be no higher than top of electrical box. Before the coil is mounted, the piping to the valves or other connection points should be made to the coil. No brazing should take place in the underside of the cabinet, as cabinet seals will be destroyed. Shield cabinet on final braze. The prepiped coil, with mounting brackets is then placed in cabinet channel and pulled forward so RH tab projects through slot in cabinet flange. The back of mounting brackets are secured to the cabinet channel with screws provided. See Figure 9. See Figure 10 for valve plug-in point on bottom of control box. WARNING: Unit must be disconnected before installation of any hydronic kit. This kit is to be used only with a Model unit for which it is intended. Figure 8
