CAUTION
Risk of equipment damage! Do not install your CT
Unit where it is subject to sudden depressurization
cycles exceeding 20 PSIG. Quick relieving air
solenoid valves, typical in some spray booths, will
eventually produce desiccant dusting.
To minimize sudden depressurization effect, replace
the existing solenoid with a "slow closing solenoid
valve". (One source; Automatic Switch Co.) Or, install
an air adjusting valve at the existing solenoid outlet.
Choose a location in your existing air piping as close to
the point of use, such as inside the spray booth and as
far from your compressor as possible. The air entering
the dryer must not exceed 100oF. You can check this
by putting your hand on the compressed air line where
you want to install the dryer, if the pipe is not
uncomfortably hot the temperature is satisfactory. Install
at a height so that the top flange can be easily removed
to replace the desiccant.
With your air compressor shut off and locked out in
accordance with OSHA regulations, and your
compressed air system depressurized, install into the
compressed air line. The installation of a manual bypass
or a 1/2" NPT ball valve before the dryer is
recommended.
Mount the dryer to the wall using the brackets and pipe
the dryer into the air system. Do not depend on the pipe
to support the dryer.
If you have a pressure regulator at the same location as
the dryer, it should be mounted after the dryer.
Complete the piping of the dryer and you are ready to
enjoy moisture free, particle free and oil free compressed
air at your chosen point of use application.
Your dryer is completely automatic and requires only
periodic draining of the water separator. Open the drain
valve daily to drain off collected water. If you drain off
more than a cup of water, open the drain more often.
Risk of injury. Components are under pressure.
Relieve air pressure before performing any
maintenance.
Replace the Desiccant Cartridge when the humidity
indicator turns yellow.
Shut off the air compressor, lock it out in accordance
with OSHA regulation and depressurize the
compressed air line serving the dryer by opening the
drain on the dryer.
Remove the top flange.
The built in humidity indicator should turn back to
green within 12 hours. If it doesn't, this means liquid
water has gotten on the indicator and washed away
the litmus solution that allows the indicator to change
color, if this happens you will need to replace the
humidity indicator with a new one.

Warning
Risk of injury. Only use a socket wrench to
remove the humidty indicator from the desiccant
tank. Immediately replace the humidity indicator if
damaged.
Take out the used Desiccant Cartridge and dispose of
properly. Inspect and/or replace the bushing located on
the inside of the tank at the outlet port. Be sure to
press it into place before installing a new desiccant
cartridge. Install new cartridge.

Put DeVilbiss gun lube on the screw threads and
reinstall the top flange on the desiccant tank,
torque screws to 25-30 ft. lbs. You are now ready to
place the dryer back into service.
