16.5.27 Outdoor High Pressure Switch Activate (F12)

Malfunction Decision Conditions:

During operation of cooling and heating, when pressure 4.5 MPa and above is detected by outdoor high pressure
switch.

Malfunction Caused:

1 Dust accumulation on the outdoor unit heat exchanger.
2 Air short circuit at outdoor unit.
3 Faulty

water

pump.

4  Insufficient water flow rate in system.
5  Water leak in system.
6  2/3 way valve closed.
7  Clogged expansion valve or strainer.
8 Excessive

refrigerant.

9 Faulty outdoor high pressure sensor and switch.
10 Faulty outdoor unit PCB.

Abnormality Judgment:

Continue 4 times in 20 minutes.

Check the system water pump.

Is the water pump working?

Check the system water passage.

- Readjust the water pump
speed
- Replace outdoor high
pressure sensor

Is the water pump speed

adjusted according to system

hydraulic external static pressure?

- Replace the faulty water
pump
- Replace outdoor high
pressure sensor

Yes

Check the system water

flow rate.

Is there any water leakage?

- Fix the system water
leakage
- Replace outdoor high
pressure sensor

Yes

- Replace the outdoor unit
PCB (main)
- Replace the outdoor high
pressure sensor and switch

Check refrigerant amount.

Is the additional refrigerant

amount filled correctly?

- Reclaim and recharge with
correct amount of refrigerant
- Replace outdoor high
pressure sensor

Yes

Check for clogged

expansion valve or strainer.

Is the expansion valve or

strainer clogged (ice formed)?

- Replace the expansion valve
and/or strainer
- Reclaim and recharge
refrigerant
- Replace outdoor high
pressure sensor

Yes

Check the dust accumulation on the

outdoor unit heat exchanger.

Is the outdoor unit heat

exchanger dirty?

Check the outdoor air

passage.

Provide sufficient air

passage.

Is there any short circuit?

Clean the heat exchanger.
