Air Conditioning Contractors of America (ACCA) is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage. These instructions and any instructions packaged with any separate equipment, required to make up the entire air conditioning system should be carefully read before beginning the installation. Note particularly any tags and/ or labels attached to the equipment. Design the duct work according to methods given by the Air Conditioning Contractors of America (ACCA). When duct runs through unheated spaces, it should be insulated with a minimum of one inch of insulation. Use insulation with a vapor barrier on the outside of the insulation. Flexible joints should be used to connect the duct work to the equipment in order to keep the noise transmission to a minimum. A 1/4 inch clearance to combustible material for the first three feet of duct attached to the outlet air frame is required. See Wall Mounting Instructions and Figures 3 and 3A for further details. Ducts through the walls must be insulated and all joints taped or sealed to prevent air or moisture entering the wall cavity. Some installations may not require any return air duct. A metallic return air grille is required with installations not requiring a return air duct. The spacing between louvers on the grille shall not be larger than 5/8 inch. NOTE: If no return air duct is used, applicable installation codes may limit this cabinet to installation only in a single story structure. Any grille that meets with 5/8 inch louver criteria may be used. It is recommended that Bard Return Air Grille Kit RG2 through RG5 or RFG2 through RFG5 be installed when no return duct is used. Contact distributor or factory for ordering information. If using a return air filter grille, filters must be of sufficient size to allow a maximum velocity of 400 fpm. CONDENSATE DRAIN A plastic drain hose extends from the drain pan at the top of the unit down to the unit base. There are openings in the unit base for the drain hose to pass through. In the event the drain hose is connected to a drain system of some type, it must be an open or vented type system to assure proper drainage. FILTERS WA6022 AND WA4822 ONLY A one inch throw away filter is supplied with each unit. The filter slides into position making it easy to service. This filter can be serviced from the outside by removing the service door. A one inch washable filter and a two inch pleated filter are also available as optional accessories. The internal filter brackets are adjustable to accommodate the two inch filter by bending the metal tabs holding the 1 inch filter down. There are two tabs on each side of the filter. NOTE: WA6023 and WA4823 models require the use of a return air filter grille. Manual 2100-348 Page 6 INSTALLATION INSTRUCTIONS WALL MOUNTING INFORMATION 1. Two holes for the supply and return air openings must be cut through the wall as shown in Figure 1 or 2. Figure 1 is for models WA4823, and WA6023. Figure 2 is for Models WA4822 and WA6022. 2. On wood frame walls, the wall construction must be strong and rigid enough to carry the weight of the unit without transmitting any unit vibration. WARING Fire hazard can result if 1/4 inch clearance to combustible materials for supply air duct is not maintained. See Figure 3. 3. Concrete block walls must be thoroughly inspected to insure that they are capable of carrying the weight of the installed unit. WA4822 AND WA6022 ONLY These units are equipped with adjustable return and supply air flanges. The flanges are adjustable side to side in 1” increments. This allows these units to be adjusted so that in side by side applications these units can replace two 2 Ton units using the same wall openings. MOUNTING THE UNIT 1. These units are secured by wall mounting brackets which secure the unit to the outside wall surface at both sides. A bottom mounting bracket is provided for ease of installation, but is not required. 2. The unit itself is suitable for 0 inch clearance, but the supply air duct flange and the first 3 feet of supply air duct require a minimum of 1/4 inch clearance to combustible material. If a combustible wall use a minimum of 30-1/2” x 10-1/2” dimensions for sizing. However it is generally recommended that a 1 inch clearance is used for ease of installation and maintaining the required clearance to combustible material. The supply air opening would then be 32” x 12”. See Figures 2 and 3 for details. WARNING Failure to provide the 1/4 inch clearance between the supply duct and a combustible surface for the first 3 feet of duct can result in fire causing damage, injury or death. 3. Locate and mark lag bolt locations and bottom mounting bracket location. See Figure 2. 4. Mount bottom mounting bracket. 5. Hook top rain flashing under back bend of top. Top rain flashing is shipped secured to the right sid...
