MAINTENANCE AND TROUBLESHOOTING
MAiNTENANCE
The heat pump is an advanced piece of equipment with
high automation. The reliability and operation life of the
heat pump can be guaranteed and even increased by
regular inspection and effective maintenance.
The external water filter should be cleaned regularly to
ensure the cleanness of the water in the system and avoid
damage caused by a blockage in the filter.
All protective settings in the unit have been set before
ex-factory. Users must not adjust it when the heat pump
unit is in use.
Regular inspection is required for the power source and
the wiring connection of the electric system. Loose wiring
connection and electric components should be repaired
in time.
The water supply system, relief valve of the water tank,
water level control device and air discharge device need
to be checked regularly in case of low circulation water
volume caused by air entering the system, to ensure
enough capacity and reliability of the heat pump.
Check the water pump and the valves on the pipes if
they work well, and make sure there is no leakage from
connector.
Keep the surrounding of the heat pump dry, clean and
ventilated. Regularly clean the evaporator to keep high heat
exchanging efficiency.
Check the inside pipe connectors and refrigerant service
port is dirty with oil. Make sure there is no refrigerant
leakage.
Before stopping the heat pump for long time, drain out
all water in the pipes, and shut off the power supply, and
put it into a shield. Full inspection of the system is required
before next operation.
Users should call the installer or the seller every time when
there is an error on the heat pump controller.
Clean the condenser with phosphoric acid of 15%
consistence under temperature of 50C-60C. Run the
circulation pump for 3 hours, and then flush with fresh
water for 3 times. When installing the pipes, add a 3 way
valve on the pipes and closed on outlet of it, for cleaning
use. Corrosive washing liquid is forbidden to clean the
condenser.
Clean the inside of the water tank after being used for a
period (usually two months, and according to local water
quality).
