5. MAINTENANCE AND INSPECTION
5.1 Maintenance
Check the water supply device and the release often. You should avoid the condition of no water or
air entering into system, as this will influence unit's performance and reliability. You should clear the
pool/spa filter regularly to avoid damage to the unit as a result of the dirty of clogged filter.
The area around the unit should be dry, clean and well ventilated. Clean the side heating
exchanger regularly to maintain good heat exchange as conserve energy .
The operation pressure of the refrigerant system should only be serviced by a certified
technician .
Check the power supply and cable connection often,.Should the unit begin to operate
abnormally, switch it off and contact the qualified technician.
Discharge all water in the water pump and water system ,so that freezing of the water in the
pump or water system does not occur. You should discharge the water at the bottom of water
pump if the unit will not be used for an extended period of time. You should check the unit
thoroughly and fill the system with water fully before using it for the first time after a
prolonged period of no usage.
