Valve

Pressure Release Valve: The pressure release valve, located on the side of the pressure switch, is designed to automatically release compressed air from the compressor head and the outlet tube when the air compressor reaches “cut-out” pressure or is

shut off. The pressure release valve allows the motor to restart freely. When the motor stops running, air

will be heard escaping from this valve for a few

seconds. No air should be heard leaking when the motor is running, or continuous leaking after unit reaches “cut-out” pressure.

Air Intake Filter (not shown) This filter is designed to clean air coming into the pump. This filter must always be clean and ventilation openings free from obstructions. See "Maintenance".

How to Use Your Unit

How to Stop:

1.Set the On/Auto/Off lever to “OFF”.

Before Starting

Break-in Procedure

Serious damage may result if the following break-in instructions are not closely followed.

This procedure is required before the air compressor is put into service and when the check valve or a complete compressor pump has been replaced.

1.Make sure the On/Auto/Off lever is in the "OFF" position.

2.Recheck all wiring. Make sure wires are secure at all terminals connections. Make sure all contacts move freely and are not obstructed.

3.Open the globe valve fully to permit air to escape and prevent air pressure build up in the air tank during the break-in period.

4.Move the On/Auto/Off lever to "ON/AUTO" position. The compressor will start.

5.Run the compressor for 20 minutes. Make sure the globe valve is open and there is minimal air pressure build-up in tank.

6.Check all air line fittings and connections/piping for air leaks by applying a soap solution. Correct if necessary. NOTE: Minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance.

7.Check for excessive vibration. Readjust or shim air compressor feet, if necessary.

8.After 20 minutes, close the globe valve.The air receiver will fill to “cut-out” pressure and the motor will stop.
