VII. Heat Pump Running Time
1. Determine the length of pump and heat pump operating time necessary for your particular
requirements. Minimum run time should be the required hours to attain proper water filtration.
Maximum run time obviously is 24 hours per day, or as required to reach desired water
temperature, and depends on such things as weather, pool/spa size, covering, shading, etc.
2. If cooler or warmer water is desired, simply adjust the water temperature control and/or the
pump and heat pump operating time accordingly, until the desired water temperature is
reached.
NOTE: At the beginning of the heating season, or whenever the pool/spa water
temperature is to be raised several degrees, the pool pump and heat pump may
need to operate continuously for several days. During summer months, only a few
hours per day may be necessary, or none at all.
VIII. Summer Shutdown
If you do not plan to use the heat pump during the summer months, secure and protect it
as follows:
1. From the control panel, turn the control switch to Remote (OFF).
2. Turn the heat pump circuit breaker or disconnect switch to OFF.
3. Leave the valves set the way they are unless additional circulation is required. DO NOT stop
all flow through the heat pump.
4. IMPORTANT: Remember to reset the valves before the next heating season, or the heat pump
will not operate properly.
IX. Freeze Protection
If the heat pump 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 heat pump circuit breaker or disconnect switch to OFF.
2. From the control panel, turn the control switch to
Remote (OFF).
3. With the pool pump OFF, close the external shutoff valves and loosen the inlet and outlet
water unions to allow water to drain.
4. Leave the drains open until the unit is started in the spring.
5. Cover the heat pump with a waterproof cover.
Continuous Pump Operation
It is also possible in some areas to prevent heat pump freeze damage by operating the pump
continuously during freezing weather. However, this results in significantly higher pump
operating cost. Further, if a sustained power failure occurs, the heat pump MUST be drained
anyway, or freeze damage could result.
