8. Maintenance and Trouble Shooting
9. Manometer Instruction
The manometer is a kind of high pressure equipment, when the heat pump is on, the manometer pointer
would point to the pressure value of refrigerant, the max. value of protection is 42kg/Cm2. When the heat
pump is off, the pointer would point to the same value as actual ambient temperature (e.g. 28°C) and related
air pressure (e.g.18kg/ Cm2 ).
Please check the manometer when you restart the heat pump after not using for a long time, if it shows
ambient temperature valve is smaller than 2C° (When the ambient temp. is higher than 2C° ), it means that
refrigerant has leaked a lot, and you need to confirm with professional engineer as soon as possible.
Maintenance
The heat pump water heater is an advanced
equipment with high automization. The
reliability and operation life of the heat pump
can be expectedly gurranteed and even
increased by regular inspection and
effective maintenance.
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.
The external water filter should be
cleaned regularly to ensure the
cleanness of the water in the system and
avoid damage caused by blockage in the
filter.
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.
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.
Users should call the installer or the
seller every time when there is an error
on the heat pump controller.
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.
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.
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 connectors.
Keep the surrounding of the heat pump
dry,
Clean the inside of the water tank
after being used for a period(usually
two months, and according to local
water quality.)
