MAINTENANCE AND INSPECTION
Check the water supply device and the release often. You should avoid the condition of no
water or air entering the system, as this will influence the 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 or
a 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 and 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 the
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
Semi-annual maintenance.
Evaporator cleaning (wash with water. Do not use pressure washer).
Clean the tray or base, taking special care in the drainage holes.
Check contactors (visual inspection and correct contactor engagement).
Check capacitors (visual inspection and capacitance measurement with the equipment
disconnected from the power supply, having to discharge before removing the connections).
Annual maintenance Check refrigerant pressure.
