Check the power supply and the electrical system, make sure the electrical components are
good, and the wiring is well. If there is a damaged part or a strange smell, please replace it in
time.
If the heat pump is not used for a long time, please drain out all the water from the unit and seal
the unit to keep it good. Please drain the water from the lowest point of the boiler to avoid
freezing in winter. Water recharge and full inspection on the heat pump is required before it is
restarted.
Do not turn the power 'OFF' when you use the unit continuously, or the water in the pipe will
freeze and split the pipe.

It is recommended to clean the tank and e-heater regularly to keep an efficient performance.
Generally no maintenance is required by the operator, except below: It is recommended to set
a lower temperature to decrease the heat release, prevent scale and save energy if the outlet
water is sufficient. Keep the unit clean by means of soft damp cloth.
