Protection Circuit
Time Delay for Restarting
Compressor Air Delivery
Auto Drain
Cleaning of Ventilation Area
Since the auto drain is designed in such a way that the valve
remains open unless the air pressure rises to 0.15MPa or higher,
air will blow out from the drain discharge port when the air
compressor starts up until the pressure increases. Therefore, if an
air compressor has a low air delivery, the pressure may not be
sufficient.
The auto drain may not function properly, depending on the quality
of compressed air. Check its operation once a day.
Remove dust from the ventilation area once a month using a
vacuum cleaner or an air blow nozzle.
Allow at least three minutes
before restarting the dryer. If
the air dryer is restarted within
three minutes after being
stopped, the protection circuit
will be activated, the operating
light goes off and the dryer will
not be activated.
Please wait
three minutes!

When the air dryer is operated under the following conditions, the
protection circuit is activated, the light goes off and operation
stops.
When compressed air
temperature is too high
When compressed air flow
rate is too high
When ambient temperature
is too high (40
C or higher)
When power supply is
beyond rated voltage by
10%
When ventilation port is obstructed by a wall or clogged with dust
Use an air compressor of 100
l
/min or greater air delivery.
Strainer, attached as air dryer's accessories, must be installed to
the inlet to prevent the foreign particles from flowing into air dryer,
which leads to the choking air dryer.
