Pool Heat Pump
OPERATION OF YOUR POOL HEAT PUMP
Initial Heating
Atmospheric conditions as well as the pool water temperature should not be below the
minimum operating temperatures as stated below in order to obtain efficiency and avoid
codes from appearing on the electronic control temperature display ; these codes are not
generally a problem with the pool heat pump at these conditions and is not covered by the
warranty.
If temperatures are below the minimum temperatures listed the pool heat pump should not
be operated and must be switched off.
For Electroheat SubZero and Reversible (XLR) units, they will automatically stop without
human intervention.

The speed of heating is dependent upon five basic factors:
1. Size of the pool.
2. How many degrees the water is to be heated.
3. Ambient air temperature - the warmer the air, the less time required to heat.
4. Use of a solar blanket .
5. The size of the pool heat pump.
To achieve initial heating, your pool heat pump and the pool pump may work up to 24 hours
per day until desired temperature is achieved. The initial heating time may vary depending
upon the above five factors. After initial heating, operating time may be reduced to match
daily heat loss.
Pool Heat Pump Running Time
Most units should be sized to operate during the pool filtering cycle time of 8-12 hours
daily, providing an even, steady flow of warm water. On warmer days the pool heat pump
will run less because the heat loss will be less. Pool heat pumps are able to operate 24
hours per day when necessary.
