Regular Maintenance of water module
Power off outdoor unit and water module
before Regular Maintenance.
Check the followings once at least every year:
(1) Water pressure
Check water pressure before startup.
Supplement water if lower than 0.1MPa.
(2) Filter
Clean water filter
(3) Safety valve
①
Operate safety valve to check whether
water flows out;
②
If no water flows out, contact local dealer.
③ If water continuously flows out, firstly close
valve on water pipeline and contact local
dealer
.
(4) Drainage hose in safety valve
Check safety valve hose drains water smoothly.
(5) Electrical box
Check electrical box is loosened or not.
(6) Water module heater
Check heater is wrapped tightly by thermal
The filter is not blocked.
There is no air in the system.
The water flow is sufficient and the temperature
is within the normal range, otherwise, the plate
heat exchanger will be freezed.
Stop the operation of the water module if a freezing occurs
inside the plate heat exchanger; do not restart the unit
before the cause of the failure is fixed; because this will lead
to a severer freezing, which will destroy the inner part of the
heat exchanger, if so, the refrigerant will leak or mix with the
water.
Regularly check water module as required
in section 14.1 “Check Before Test Run”.

③
Check the following items
