The fault and exclude way of the dryer
Cannot start
Check the power supply voltage is normal or not; refrigerant pressure is normal or not
(normal is stop state 5-12kg); 220V/12V transformer, 12V is normal or not; the start and
stop button on the panel is normal or not, AC contactor coil of contact point is normal
or not; the pressure switch, thermal relay is reset or not, the above fault is AC contactor
can not pull
The AC contactor can pull but can not start and run
Check the compressor connection line, the contact of wiring plug is normal or not,
capacitor is damaged or decreased capacity, the overload protector is damaged or not;
compressor coil is open or short circuit Above shall confirm the damaged parts and
replace with the new parts
Can start but stop a little late
Low pressure fault: not enough refrigerant, check the leak point, after confirm the leak
point and repair it and then reevacuated and filling the refrigerant
High pressure fault, too dust on the condenser, or the condition temperature is too high,
it should wash the condenser and improve the ventilation condition
The gas is reduced or not by the compressed air
Ice block or too much dust, the reason of ice block: the load is reduced, the pressure
controller to be failure. Remedy is to readjust the temperature controller or pressure
switch., the method is：start, watching the pressure meter gauge, when reach 4 kg, the
machine should be stopped, watch several times. If can not be adjusted. It should be
replaced the dust should be cleaned.
Not cooling (the drainage has a long time without water discharge) but can hear the
compressor running sound. Owing to the damage to the compressor valve plate, it
should replace the compressor, it is not compress the refrigerant (the refrigerant
pressure gauge pointer does not move)
The head frost
Remedy should accord to the article 3 ice block fault (adjust the fan control switch)
Fault exclude
The fault of air dryer and external factors, the way of fault exclude is as following
The air pressure to be reduced too much
