5.1 Maintenance and Inspection
You should eliminate causes of prime loss and ensure unrestricted water flow. Clear debris from the pool/spa and pump
baskets regularly to avoid damage to the heat pump. Ensure the area around the heat pump is well ventilated and free
from debris and flooding. The evaporator/condenser should be well maintained at all times with no obstructions that will
affect the heat pumps performance.
WARNING: If debris such as leaves accumulate inside the unit, they could block the drain hole and cause corrosion to the
heat pump.
A refrigeration mechanic should be employed to do periodic maintenance to the heat pump, including cleaning the
condenser, checking gas levels and removing debris from inside the unit.
NOTE:
Should the heat pump start working abnormally, switch it off and contact your authorized Poolrite technician.
If the heat pump is not to be used for an extended period of time then isolate power to the unit, and empty the heat
exchanger of water. This will avoid internal damage to the heat exchanger. It is advised to flush the heat exchanger with
non chlorinated fresh water or town water.
NOTE:
The heat pump must be fully charged with water before power is restored, to avoid any damage to the unit.
