temperatures, if it is
out of range, change
the sensor.

5. There is air
inside the
refrigerant
system or
refrigerant
volume is too
high.
1. If the error displays before the
compressor starts, it means high pressure
switch error. Please reconnect high
pressure switch or change the switch. If
the error displays when water temp is
about 104°F, please check if the high
pressure switch or mid pressure switch is
misconnected by mistake. Refer to the
wiring diagram.
2. Clean and purge the air from the water
circuit.
3. Clean the Water circuit filter or add a
bigger water pump if water flow is not
enough.
4. Open the thermostatic expansion valve
360~180°,
5. Measure the refrigerant pressure, re-
vacuum the system and recharge the
refrigerant.
