Fault Analysis
6. Refrigerant system is mixed with
air, maybe the vacuum is not enough.
1. The connection between low
pressure switch and main board is
poor.
2. There is something wrong with low
pressure switch.
3. Main board is broken.
4. Poor evaporation effect.
4.1 Improper installation position.
4.2 Dust, foreign body blockage on
the finned heat exchanger, etc.
4.3 Low ambient temp..
4.4 Fan motor failure causes
abnormal air inlet.
5. Refrigerant road blockage, may
appear in the throttle part.
6. Leakage happen,and refrigerant is
not enough.
1. The connection between wire
controller and main board is poor.
2.Wire controller fault.
3. Main board fault (Er 10 appears
only for this reason).
4. Communication wire and strong
electricity wire put together, resulting
in power interference
communication.
1. Temp. sensor fault.
2. Water flow switch fault.
3. Leakage happen, and refrigerant
is not enough.
4. Low water flow.
4.1 The water system is blocked.
4.2 Water pump is not suitable.
4.3 Water pipe is small.
4.4 The water flow switch is stuck
and cannot be reset.
5. No water flow.
5.1 The valve is not open.
5.2 The water pump is not working.
5.3 Water pump is broken.
1. Reconnect the low pressure
switch cable.
2. Replace the low pressure switch.
3. Replace the main board.
4.1 Readjust the position, the
distance of the device from the wall
should not be too close.
4.2 Clean up the dust and dirty
matter on the finned heat
exchanger.
4.3 Operate within the allowable
ambient temp. range.
4.4 Replace the fan motor.
5. Replace the blocked part.
6. Repair the leakage, and refill the
refrigerant according to the
nameplate.
1. Reconnect the wire controller
cable.
2. Replace the wire controller.
3. Replace the main board.
4. Communication wire is placed
separately from the strong electricity
wire.
1.Replace the temp. sensor.
2. Replace the water flow switch.
3. Repair the leakage, and refill the
refrigerant according to the
nameplate.
4.1 Clean or replace the blocked
part.
4.2 Change the pump according to
the water flow and water head.
4.3 Change the water pipe.
4.4 Reset the water flow switch
manually.
5.1 Open the valve.
5.2 Turn on the pump.
5.3 Replace the water pump.
