2.0 GENERAL INFORMATION 2.1 IMPORTANT INFORMATION ABOUT EFFICIENCY & INDOOR AIR QUALITY Central cooling and heating equipment is only as efficient as the duct system that car- ries the cooled or heated air. To maintain efficiency, comfort and good indoor air qual- ity, it is important to have the proper balance between the air being supplied to each room and the air returning to the cooling and heating equipment. -

Page 12: Importance Of Proper Indoor/Outdoor Match-Ups
2.8 IMPORTANCE OF PROPER INDOOR/OUTDOOR MATCH-UPS To assure many years of reliable operation and optimum customer comfort and to assure the outdoor unit warranty remains valid, an air-handler model should be selected that is properly matched to the outdoor unit. This is especially critical for heat pump systems to assure proper refrigerant charge balance between the cooling and heating modes. -

Page 14: Applications & Orientation
3.2 APPLICATIONS & ORIENTATION IMPORTANT: The air-handler is suitable for indoor applications only. 3.2.1 HORIZONTAL DISCHARGE The air-handler may be installed in the horizontal discharge configuration with either a vertical or horizontal return duct as shown in Figure 2. For a vertical return duct, relo- cate the return air panel on top of the air-handler to cover the side return air opening. -
Page 15: Applications Requiring Electric Heat
3.2.3 APPLICATIONS REQUIRING ELECTRIC HEAT For applications that require resistance electric heat, field installed heater kits are avail- able that attaches to the discharge side of the air-handler. See Figure 4. The heater kit is compatible for both horizontal and vertical discharge applications. The supply duct must be attached to the discharge end of the heater kit. -
Page 16: Auxiliary Overflow Pan
3.3 AUXILIARY OVERFLOW PAN In compliance with recognized codes, an auxiliary overflow pan must installed under all equipment containing evaporator coils that are located in any area of a structure where damage to the building or building contents may occur as a result of an overflow of the coil drain pan or a stoppage in the primary condensate drain piping. -
Page 17: Refrigerant Line Connections & Charging
3.7 REFRIGERANT LINE CONNECTIONS & CHARGING 3.7.1 PREPARATION The coil is shipped with a low pressure (5-10 psig) charge of dry nitrogen which will be released when the rubber plugs are removed. Leave the rubber plugs in the refrigerant connection stubs on the air-handler until the refrigerant lines are ready to be brazed to the refrigerant connection stubs to prevent contaminants from entering the coil. -
Page 18: Refrigerant Lines
3.7.3 REFRIGERANT LINES The following will be of help in accomplishing a successful installation. 1. Size liquid line for no more than 50 PSIG pressure drop. 2. Size suction lines for no more than 2°F loss which corresponds to approximately 5 PSIG pressure drop. -
Page 19: Brazing
3.7.5 BRAZING Air inside the tubing and coil should be displaced with dry nitrogen prior to the brazing process to prevent the formation of harmful copper oxide inside the tubing. It is very important not to pressurize the system with nitrogen while brazing or pin-hole leaks will form in the braze joint. -
Page 20: Condensate Drain
3.9 CONDENSATE DRAIN Two drain connections are provided, one on each side of the unit. Plug the unused drain connection using the plug provided in the parts bag. Consult local codes or ordinances for specific requirements. IMPORTANT: When making drain fitting connections to the drain pan, use a thin layer of Teflon paste, silicone or Teflon tape and install hand tight. -

3.11 ELECTRICAL WIRING Field wiring must comply with the National Electric Code (C.E.C. in Canada) and any applicable local ordinance. 3.11.1 POWER WIRING It is important that proper electrical power is available for connection to the unit model being installed. See the unit nameplate, wiring diagram and electrical data in the instal- lation instructions. -
