Installation

Installation

CAUTION

Do not hang the air control unit directly off a pump air motor inlet, which could be damaged by the weight of the unit and operating stress.

Before installing air line components, blow out the pipe line to remove debris. Be sure air to the regulator is clean. Erratic operation or loss of regulation is usually caused by dirt in the regulator.

Use pipe compound or tape sparingly and only on male threads. Locate the regulator as close as possible to the equipment it serves.

Install a main air shutoff valve upstream from the air controls to isolate them for service.

Operation

Operation

Pressure Adjustment

WARNING

Do not exceed the Maximum Incoming Air Pressure of the equipment. Over pressurizing can cause component rupture and serious injury.

Turn clockwise to increase air pressure. Turn counterclockwise to decrease air pressure.

Pressure Relief Procedure

WARNING

To avoid injury, relieve air and fluid pressure before checking, cleaning, or repairing the equipment.

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.

You can push the piston stem on the bottom of the bowl to manually drain it.
