Drain connections must be made
before the dryer can be operated. The
dryers are fully automatic and require
no auxiliary controls.

dryer. Reference dryer indentations
and instruction tag for appropriate
inlet and outlet connections.
. Route drain connections to a
condensate separator or approved
collection point.
3. Turn the on/off switch to on. Double
check connections.
4. After the dryer has been running for
30 minutes:
a. Check that on/off lighted
switch is glowing. If light is
not glowing, unplug unit and
refer to Field Service Guide for
additional information or call
your local distributor.
b. Confirm that condensate is
discharging from the drain. This
can only be done when there is
air flow through the dryer.
Reference Serial Number Tag for
appropriate power requirement/connection
rating. Make other dryer connections prior
to connecting power source.
The dryer is designed to run continuously.
Let the dryer run even when the demand
for compressed air is interrupted; the dryer
will not freeze up.
