How to Stop, Before Starting, Check Valve

Check Valve: When the air compressor is operating, the check valve is “open”, allowing compressed air to enter the air tank. When the air compressor reaches “cut-out” pressure, the check valve “closes”, allowing air pressure to remain inside the air tank.

Check 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 15 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.
