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 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 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 your qualified technician.
• Discharge all water in the water pump and water system, so that freezing of the water-inlet 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 after a prolonged period of no usage.
5.2 Trouble Shooting Guide
Malfunction
LED
Controller
Reason Resolution
Water-inlet temperature sensor
failure
PP1
The sensor is open or there is a
short circuit
Check or change the sensor
Water-outlet temperature sensor
failure
PP2
The sensor is open or there is a
short circuit
Check or change the sensor
Coil sensor failure PP3
The sensor is open or there is a
short circuit
Check or change the sensor
Ambient sensor failure PP5
The sensor is open or there is a
short circuit
Check or change the sensor
The temperature difference between
the water-inlet and water-outlet is
too large
PP6
Water flow volume is not enough,
water pressure difference is too
low/too large
Check the water flow volume, or
system obstruction.
Defrost cycle PP7 Outlet water is too low
Check the water flow volume or
outlet water temperature sensor
First level frost protection in winter PP7
Ambient or inlet water temperature
is too low
Second level frost protection in
winter
PP7
Ambient or inlet water temperature
is even lower
High pressure protection EE1
Gas System pressure is too high,
or water flow rate is too low, or
evaporator is clogged, or air flow
is too low
Check the high pressure switch and
the gas system pressure to see
whether the gas loop is blocked.
Check the water flow volume. Check
that the evaporator coil is clean.
Check the fan rotation speed
Low pressure protection EE2
Gas System pressure is too low, or
air flow is too low or evaporator coil
is clogged
Check the low pressure switch and
the gas system pressure to see
whether there is a leak
Flow switch failure EE3
No water/little water in water
system
Check the water flow volume, check
if the water pump and flow switch
has failed
PP6 alarm code occurred 3 times in
30 minutes
EE5 Water flow rate not enough
Check the water flow rate, check if
the water system is jammed
Defrosting cycle
Defrost Code
Display
Communication failure EE8
LED controller or PCB connection
failure
Check the wire connection
