Filter Maintenance
To remove filter element: twist the filter bowl 1/8 turn clockwise
(CW). Then pull the bowl down to expose the filter element.
To remove the filter element, unscrew the baffle (this will
allow element removal).
To clean filter element use soap and water.

Note
When replacing the filter element bowl, care must
be taken to ensure that the O-Ring does not get
pinched.
Regulator Operation
The adjustment knob simply acts upon a spring rest located
on the spring and directly compresses the spring as it is
adjusted. A non-rising low torque adjustment screw is used
on this type of filter and regulator. The upper spring rest is
located on top of the regulator spring and transmits force
from the adjustment screw to the spring. Regulators use
simple wire coil springs for controlling the downstream
regulator pressure. The bonnet houses the adjustment
spring and is used to help retain the diaphragm. The
diaphragm moves up when the downstream pressure
reaches its preset pressure level, which in turn closes the
valve. A self-relieving regulator is designed to automatically
relieve overpressure in the secondary side of the regulator.
Note
This self-relieving feature is not designed to bleed
the downstream pressure.
Dryer must be provided with a clean, dry, and regulated
80 psi +/- 10 psi (5.51 bar +/- 0.68 bar) air supply (equivalent
volume = 11 cfh [0.31 cmh]).
The regulator should be set at 80 psi +/- 10 psi (5.51 bar
The regulator should be set at 80 psi +/- 10 psi (5.51 bar
+/- 0.68 bar). To set pressure, pull the adjusting knob up and
either turn the knob clockwise (CW) to increase the pressure
or counterclockwise (CCW) to decrease the pressure.
The dryer is equipped with a pneumatically operated heat
The dryer is equipped with a pneumatically operated heat
reclaimer damper, which when opened, will recirculate
approximately fifteen percent (15%) of the dryers exhaust air.
The heat reclaimer dampener is closed until ignition of flame
The heat reclaimer dampener is closed until ignition of flame
has been established. Then, the damper piston is
actuated, opening the damper and recirculating fifteen percent
(15%) of the exhaust air back over the gas burner
and into the tumbler. The damper remains open for the rest
of the drying cycle. On cool down, the damper closes,
exhausting all of the 13,000 cfm which ensures a fast cool
down of the load.
Note
Gas Dryers must have a "Y" dimension of 1-3/16".

Varistor (MOV [Metal Oxide Varistor])
Description
The varistor (MOV) is used to suppress any inductive electrical
spikes produced by the energizing and coil voltage.
Varistor (MOV) Replacement
1. Discontinue electrical service to the dryer.
2. Loosen the screws marked A1 and A2 on the contactor.
3. Verify that no additional wires were inadvertently
2. Loosen the screws marked A1 and A2 on the contactor.
3. Verify that no additional wires were inadvertently
removed.
4. Reverse above procedure to install new varistor.
Filter/Regulator Assembly ___________
The purpose of the filter is to remove bulk liquids and solid
particles from the compressed air stream. The filter element
provides mechanical separation of solids. Centrifugal force
inside the filter bowl separates bulk liquids and larger solid
particles.
The filter consists of a louver, which causes a centrifugal
The filter consists of a louver, which causes a centrifugal
spinning action to separate contaminants. A filter, which
mechanically separates contaminants is also present. The
filter bowl collects the contaminants and a baffle prevents
turbulence from picking up contaminants at the bottom of the
bowl and returning them to the air stream.
