Check the place of installation (blockage of
air inlet & outlet)
Check the excess gas
Check the power voltage
(230V)
-
Method of check
Turn off the power supply, wait for about
3 minutes, then power up again
Check loose cable connections and
contacts of reactor
Check the resistance by tester
Check the resistance by tester
Check temperature difference of
Outgoing/Return water (see Monitor
display function)
Large difference means flow rate is too
low
Check the voltage of Pump
Check the pump and water circuit
Check loose cable connections and
contacts
Check the resistance by tester
Check the service valve and refrigerant
circuit (pipe)
Check the electric continuity of Fuse
CF1 by tester
Check the resistance of 4way valve by
tester
Check the resistance of Defrost heater
by tester
Check the blockage of air inlet & outlet
Check the resistance by tester
Check the service valve and refrigerant
circuit (pipe)
Check temperature difference of
Outgoing/Return water (see Monitor
display function)
Large difference means flow rate is too
low

If excess gas is observed, collect all
refrigerant once, then recharge with
prescribed mass
Confirm the power supply voltage
(230V)
Restart operation
Troubleshooting
If the same error code appears,
Main PCB should be replaced
If the sensor is faulty, it should be
replaced
If the sensor is faulty, it should be
replaced
Make sure the position doesn't block the
air inlet and outlet
Remove the blockage, then restart
operation
If the voltage is normal, Pump should be
replaced
If the voltage is abnormal, Main PCB
should be replaced
Remove the blockage, then restart
operation
If the same error code appears, high
pressure switch should be replaced
If the compressor overheat protection
relay is blown, it should be replaced
Correct refrigerant once, then recharge
with prescribed mass
If CF2 is blown,it should be replaced and
check the resistance of 4way valve and the
resistance of Defrost heater by tester
If 4way valve is blown,it should be
replaced
If Defrost heater is blown,it should be
replaced
Ensure the installation position to avoid
blockage of air inlet & outlet
If any of these sensors is faulty, it should be
replaced
After fixing the leakage point,collect the
refrigerant once,then recharge with
prescribed mass
Remove the blockage,then restart
operation
