Page 3: Installation And Operating
The importance of proper installation cannot be overemphasized. The best designed unit wll appear to operate poorly if installed improperly. Unlike the small appliance where quality of operation can usually be determined as it leaves the factory, the performance of a heat pump depends, to a large extent, on its installation. -

• It is very important that the ducts for a serf-contained system be properly sized, installed, sealed, and insulated for the best performance of the system. It is recommended that both the supply and the retum duct be insulated (2") when installed in an unconditioned area. Where the supply duct is exposed to the outdoor temperatures, vapor barrier material should be used. -

Normally, the unit is installed outdoors either on the roof or ground, where practical. In normal roof installation, the unit is placed on an angle iron frame, and where required in some instances, isolated from the frame with rubber, cork or spdng mounts. These mounts are to help eliminate vibration and noise. -

COMPONENTS WITH SPECIAL SCROLL COMPRESSOR: Units equipped with scroll compressors do not have crankcase heaters and do not require hard start kits. However, they do have a 3 minute anti-short cycle timer. On three phase compressor, incorrect phase sequence will result in the compressor running backwards. CAUTION: Never use the scroll compressor to pump itself down (create a vacuum) by closingoff the suction line. - Page 8 In areas where the winter temperatures are low, a 30 minute setting is recommended. The heat pump is equipped with an electronic defrost control. This solid state defrost control operates in conjunction with an extemal sensor located at a "cold"spot on the outdoor coil. The control operates on a "Time/Temp"...
