Fault P2: High pressure fault

Check the heat exchanger of the outdoor unit

and indoor unit. Are the heat exchangers

clean?

Clean the heat exchangers.

YES

Are the corner shut-off valves open?

Open corner shut-off valves

YES

Refrigerant cannot circulate. Possibly due to

internal contamination or kinked lines.

Fault P3: Refrigerant level low

Are the corner shut-off valves open?

Clean the heat exchangers.

YES

Check the joints of the refrigerant circuit for

leaks. Are oily areas present?

YES

Perform an overpressure leak test. Is the

cooling circuit tight?

Rectify the leak. Adjust the refrigerant quan-

tity.

YES

Extract the refrigerant and check the refrig-

erant fill quantity. Refill the refrigerant to the

appropriate fill quantity.

Fault P4: Outdoor unit heat exchanger probe overtemperature

Check the heater exchanger of the outdoor

unit. Is the heat exchanger clean?

Clean the heat exchangers.

YES

Is the fan motor working correctly?

Check fan motor.

YES

Refrigerant cannot circulate. Possibly due to

internal contamination or kinked lines.
