Comments
The unit will not run or
cycles off and on.
Excessive ambient temperature
Designed conditions and cor-
rection factors are described
in dryer . Be sure that dryer is
working lower than design
conditions.
A high ambient temperature may cause the refrigerant
system to operate at higher than normal pressures.
Results will be a higher than normal evaporator
temperature.
Important: there should be adequate air circulation
around the dryer, and proper ventilation in the
equipment room should guarantee a low enough
ambienttemperature.
Clogged condenser fins
Clear fins of all obstructions.
The clogged fins in the condenser will restrict the air
passage and reduce the refrigeration capacity,
causing high temperature in the evaporator.
Fins should be periodically checked and cleaned.
Shortage of refrigerant
Fix the leak and add a charge
of refrigerant.
Loss of refrigerant will cause improper functioning.
Dryers are equipped with a temperature switch which
maintains the amount of refrigerant to maintain
proper cooling of the compressor.
A shortage of refrigerant may cause suction line to
become very hot, causing the temperature switch
to trip. A qualified refrigeration specialist should
perform the necessary repairs.
Error sign occurs on
digital temperature
control device
The dew point is too low or too high.
Check refrigerant gas and
make sure that the working
conditions are within the cor-
rect range.
If there is not enough refrigerant gas or if the working
temperature and inlet temperatures are very high,
the dew point will increase.
