Maintenance & Troubleshooting
Common error/protection and maintenance
Code Error
Low pressure protection/
PF pressure valve break
down/Refrigerant leak
E4 High pressure protection
P3 Water temp sensor error
P1 Coil temp sensor error
P2 Discharge air sensor error
Discharge temp protection
E3
(Discharge temp is too high)
PD Water flow switch error
Remark：the machine off code ：
1- Power off 2- meet set temperature
5- Defrosting preparation 6- Defrosting off 7-Mode change 8- Exhaust air temp is too high, then stop the machine.
9-Low-pressure switch cutting
12-Pipe-temperature resistance's breakdown 13-ambientl temperature resistance's breakdown
The manometer instruction
After off season before restart the unit, the user is advised to check this manometer,
if ambient temperature valve is smaller than 2℃ which the pointer points to, it means
that refrigerant has leaked a lot, and need to confirm with professional engineer asap.
1 The ambient temperature is too low
2 The expansion valve can not open.
3 Refrigerant leak.
1 The ambient temperature is too
high.
2 Too high water temperature setting.
3 Refrigerant overcharge.
1 The sensor is damaged.
2 The sensor is not well connected
with the circuit board.
1 The sensor is damaged.
2 The sensor is not well connected
with the circuit board.
1 The sensor is damaged.
2 The sensor is not well connected
with the circuit board.
1 No water flow through the heat
exchanger
2 Refrigerant leak
3 The expansion valve can not open.
3- Water-switch breakdown 4-anti-frozen finishing. then stop the machine
10- High-pressure switch cutting
This manometer is a kind of high pressure equipment
when unit is on, the pointer would point to high
pressure of refrigerant, the max protection value
is 42kg/cm
point to same value as actual ambient
temperature(e.g.28℃)and related
pressure(18kg/cm

Cause
1 Wait until ambient is higher than
2 Change the expansion valve.
3 Check out and mend the leak,
1 Wait until ambient is lower than
2 Set the water temp lower .
3 Discharge some refrigerant.
1 Change the sensor.
2 Reconnected the sensor with the
