Operation
Pressure Adjustment
Turn clockwise to increase air pressure. Turn
counterclockwise to decrease air pressure.
Pressure Relief Procedure
The following is a basic pressure relief procedure. Be
sure to follow the specific pressure relief procedure in
your spray gun and/or fluid supply equipment manuals.
1. Close the main air shutoff valve.
2. Trigger the gun or dispense valve and open any
drain valves to relieve pressure.
Maintenance and Repair
Air Filter
Follow the Pressure Relief Procedure before
performing any of the following procedures.
Wash the filter element and bowl with household soap
and water or denatured alcohol. Use compressed air to
blow dirt and contaminants out of the filter body. Blow
out the filter element from the inside.
Clean the air filter regularly to maximize filtering
efficiency and to avoid excessive pressure drop. Fully
relieve pressure before removing the bowl.
Auto Drain
When the filter bowl is pressurized, the piston travels
down against the spring and closes the drain opening.
When the bowl is depressurized (i.e., overnight when
system is shut down), the spring lifts the piston from the
seal, allowing the bowl to drain.
Air Regulator
See Air Regulator Manual 309924 for maintenance and
repair procedures.
Do not exceed the Maximum Incoming Air Pressure of
the equipment. Over pressurizing can cause compo-
nent rupture and serious injury.
To avoid injury, relieve air and fluid pressure before
checking, cleaning, or repairing the equipment.
You can push the piston stem on the bottom of the
bowl to manually drain it.
