6.Maintenance and Repair
6.1 Maintenance
Check the water supply and air vent frequently, to avoid lack of water or air in the water
loop. Clean the water filter in a certain period to keep good water quality. Lack of water
and dirty water can damage the unit. The heat pump will start the water pump per 72 hours
when it is not running, to avoid freezing.
Keep the unit in a place which is dry and clean, and has good ventilation. Clean the heat
exchanger in 1 or 2 month and keep good heat exchange rate and save energy.
Check each part of the unit and the pressure of the system. Replace the failure part if
there is any, and recharge the refrigerant if it is needed.
If the heat pump is not used for a long time, please drain out all the water in the unit and
seal the unit to keep it good. Please drain the water from the lowest point of the heat
exchanger to avoid freezing in winter. Water recharge and full inspection on the heat
pump is needed before it is restarted.
Check the power supply and the electrical system, make sure the electrical components
are good, the wiring is well. If there is any part failed with wrong action or smell, please
replace in time.
Don't power off the unit when you use it incontinuity, or the water in the pipe will freeze and
split the pipe. We will not answer for this damage.
Check magnesium anode every 12 months and replace as soon as possible if needed.
