7.Trouble shooting guide
Malfunction
Unit not
running
Heating
Capacity is low
Compressor
not running
Water pump
not running
Compressor
ruinning
noisily
Fan not
running
Exhaust
Pressure is too
high
Compressor is
running,but the
unit is not
heating
Note: after-sales service and warranty must be appropriately qualified
professional and technical staff under the technical services provided
by the Division I manual operation, not to their own operations to avoid
unnecessary losses and damage.
Reason
1.Power Failure
2.Unit power cable loose
3.Unit control power fuse is fusing
1.Water filter is clogging
2.Insufficient refrigerant
3.water system insulation is not
well
4.Dry filter clogging
5. Bad air heat exchanger cooling
1. Power Failure
2Compressor contactor damage
3.Connection loose
4.The compressor thermal
protection
5. The water outlet temperature is
too high
6.Compressor capacitor failure
1. Power Failure
2.Connection loose
3.Pump motor burned
1Liquid refrigerant entering the
compressor
2.Compressor internal parts is
damage
1.The Fan screws is loose
2. Fan motor burned
1.Refrigerant excessive
2.There is non-condensable gases
is the Fluoro system
1. All the refrigerant is leaks
2. Compressor failure
3.Four-way valve is leakage
Resolution
1. Disconnect the power switch, check the
power supply, power supply for the three-
phase, check the correct phase sequence
2.To connect the loose power cord
3.Identify the cause and replace the same
fuse
1.clean the filters
2.leak detection and fill the refrigerant
3.Strengthen the water system insulation
4.Replace the filter drier
5.Clean the air heat exchanger
1. Identify the cause and resolve faults
2. Replace the contactor
3To identify and repair the loose points
4.start the unit after identify the reasons
and solved
5.To re-set the water temperature
6. Replace the compressor capacitor
1.Identify the cause and resolve faults
2.To identify and repair the loose points
3. Replace the water pump
1.Check the expansion valve
2.Replace the compressor
1.Tighten the screws
2.Replace the fan
1.Emit excess refrigerant
2. Discharge non-condensable gases
1.leak detection and fill the refrigerant
2.Replace the compressor
3.Replace the four-way valve
