6.1 Maintenance and Cleaning for User
It is good practice to inspect your heat pump regularly. Maintenance should be carried out at least
annually to maintain a good lifespan of your heat pump.
1. Regularly clean the Y type filters every 6 months to ensure that the system is clean and to
avoid blockage to the system.
2. Units should be kept clean (no leaves or dirt) and no obstructions should be placed in front of
or behind the unit. Good ventilation and regular cleaning (3-6 months) of the evaporator will
help maintain efficiency.
3. Ensure the unit has power in the winter whether the unit is used or not.

not leaking.
