1. Heat exchanger cover is not removed. Remove it.
2. Heat exchanger is dirty or something is block on the surface.
Clean the heat exchanger or remove the obstruction.
3. There is no enough space around the unit for heat
exchanging.
4. fan motor is broken, replace a new one.
1.The water inlet/outlet sensor wire connector is loosen.
Reconnect it.
2.The water inlet/outlet

sensor is broken,
Change a new sensor.
3. Four-way valve is blocked. Restart the unit again to let the
valve change the direction.
4.Four-way valve is broken, change a new valve.
Unit will return to the normal operation automatically.
Clean the fines. If the fin is clean, contact your local dealer.
DC generatrix voltage is too
low
1. Check the power supply.
2. If the power supply is OK,and check if LED light is OK,
check the voltage PN, if it is 380V, the problem usually comes
from the main board. And if the light is OFF, disconnect the
power, check the IGBT, check those dioxides, if the voltage is
not correct, the inverter board is damaged, change it.
3. And if those IGBT are OK, which means the inverter board is
OK, power form rectifier bridge is not correct, check the bridge.
(Same method as IGBT, disconnect the power, check those
dioxides are damaged or not).
4. Usually if F1 exist when compressor start, the possible
reason is main board. If F1 exist when fan start, it may be
because of inverter board.
