Should any problem occur, inspect the following table, and if the problem cannot be solved, shut off the power supply and
then contact one of our sales offices for further instructions.
Problem Probable
Causes
Remedy
Power cord or plug is in loosening state
or completely pulling out.
Perform proper connection on the power cord and plug.
Air dryer does not
operate and running
lamp does not light on,
even switch is ON.
Circuit breaker is OFF.
Confirm whether the proper capacity of the circuit
breaker is used.
It is not possible to restart the air dryer within 3
minutes after shutdown. Wait for 3 minutes before
restarting.
Resume the operation after resetting the circuit
breaker to ON. If the circuit breaker still trips to OFF,
failure of electrical insulation may have occurred.
Remove the power supply and contact one of our
agents for further instructions.
Installation place is poorly
ventilated. Ambient temperature
is too high.
Improve the ventilation system to lower the ambient
temperature.
The ventilation grilles are
obstructed by wall or clogged
with dust.
Install the air dryer more than 40cm away from the
wall.
Clean the ventilation grilles once a month.
Temperature of the compressed
air is too high.
Improve the ventilation system around air
compressor or make ambient temperature around air
compressor low to lower the temperature of
discharge from compressor.
Reduce the temperature of the compressed air by
installing an additional after-cooler after air dryer.
Running lamp
extinguishes and
compressor stops
during operation but
resumes normal
operation
illuminating the
lamp after a
period of time.
Supply voltage is not in the
following range:
100VAC: 90V ~ 110V/90V ~
121V (50/60Hz)
200VAC: 180V ~ 220V/180V ~
242V (50/60Hz)
Set the voltage to a proper value by installing a
transformer or review the electrical wiring.
Installation place is poorly
ventilated. Ambient temperature
is too high.
Improve the ventilation system to lower the ambient
temperature.
The ventilation grilles are
obstructed by wall or clogged
with dust.
Install the air dryer more than 40cm away from the
wall.
Clean the ventilation grilles once a month.
Evaporation
thermometer indicates
higher than green zone.
Temperature of the compressed
air is too high.
Improve the ventilation system around air
compressor or make ambient temperature around air
compressor low to lower the temperature of
discharge from compressor.
Reduce the temperature of the compressed air by
installing an additional after-cooler after air dryer.
Bypass valve of air dryer is not
fully closed.
Close the valve completely.
Drain is not discharged from auto
drain properly.
Check if the drain pipe has been raisen up or bent.
Check auto drain.
Check auto drain strainer.
Moisture occurs
downstream of the
compressed air
lines.
Confluence of piping with another
unit without air dryer.
Install air dryer on the line that does not have it.
Separate two lines not to converge.
Large pressure drop
IN / OUT valve on the air dryer
side is not fully opened.
Open IN/OUT valve thoroughly.
