Page 11: Ductwork
3.0 DUCTWORK Ductwork should be sized and installed by the installing contractor in accor- dance with the Manual D from the Air Conditioning Contractors of America, and all national, state and local codes. NOTE On ductwork exposed to outside air space, use at least 2” of insulation and a vapor barrier. -
Page 12: Filters
5.0 FILTERS Units are shipped without a filter or filter racks. It is the responsibility of the installer to secure a filter in the return air ductwork or install a filter/frame Kit. Filter must always be used and must be kept clean. Dirty filters may cause insufficient air delivery, decreasing unit efficiency and increasing operation costs and wear-and tear on the unit and controls. -

Page 24: System Operation
8.0 SYSTEM OPERATION 8.1 COMPRESSOR CRANKCASE HEATER(OPTIONAL) Refrigerant migration during the off cycle can result in a noisy start up. Add a crankcase heater to minimize refrigeration migration, and to help eliminate any start up noise or bearing “wash out”. All heaters are located on the lower half of the compressor shell. -
Page 25: Defrost Mode
Low pressure protection When low pressure is ＜21PSIG,the compressor and the outdoor fan motor will stop running. When low pressure is ＞44PSIG,the compressor and the outdoor fan motor will resume running(3 minutes delay necessary ). In stand-by status, if low pressure protection was detected, the compressor will not start. -
