As with all heat pump pool heaters, compared to other types of heaters such as gas or oil-fired, this heat pump pool heater has lower heating capacity on a BTUH/hr basis. As a result, it will be required to operate longer to accomplish the desired results. It may, at certain times, operate as much as 24 hours per day. However, this should not be of concern to the owner, because the unit is designed to operate continuously. Even though it may operate continuously for many hours, it will still hea

Always satisfy applicable codes and standards. • In sizing power wiring, be especially aware of up- sizing requirements necessary due to wiring distances. Always satisfy applicable codes and standards. • Electrical installation should be done by a licensed electrician only. This unit is pre-wired to work with external control systems, heat-on-demand options and other external time clock overrides. Refer to the external control system’s instructions, and page 19 of this manual, for installation i

Freeze Protection If the unit is installed in a location subject to freezing conditions, it is important to protect the water circuit from freezing, just as should be done for the pump and filter. System Drain-Down 1. Turn the unit circuit breaker or disconnect switch to OFF. 2. With the pool pump OFF, close the external shutoff valves and loosen the inlet and outlet water unions to allow water to drain. Use a Wet/Dry Vac or air pressure to remove excess water. 3.
