Page 7: Positioning Equipment
1.1 Positioning Equipment Failure to heed the following may result in damage to equipment. NOTICE Do not install equipment inside of a building. Outdoor Use Only Do not install equipment inside of a room or building. Heat Pumps require unobstructed airflow for proper operation. Heat Pumps should never be installed indoors or in a location where airflow is restricted. -
Page 8: Clearances
1.2 Clearances Proper air circulation is required for the heat pump to operate efficiently. The following diagrams show the minimum clearances required for the proper operation of the heat pump.

Page 16: In-Line Chlorine Feeders
1.4.d In-Line Chlorine Feeders Place in-line chlorinators downstream from the heat pump and as low in elevation as possible. If an erosion type feeder is used, it is recommended that a Hartford Loop be installed to protect internal heat pump components. A Hartford Loop is not necessary with a Salt Chlorine Generator. - Page 17 flow rates. This requires the filter to be cleaned or back-washed. Keep baskets free of debris. A large quantity of debris in the pump and skimmer baskets can reduce water flow. Check for improper valve settings. A partially closed valve after the filter, or a full-open bypass around the heat pump, will cause insufficient water flow through the heat pump.
