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.

 

 

 

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

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.

 

 

 

 

 

How to Use Your Unit

How to Stop:

1.Set the On/Auto/Off lever to "OFF".

Before Starting

Break-in instructions

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.

NOTE: If quick connect is installed, pull coupler back until it clicks to prevent air from escaping through the quick connect.

2.Plug the power cord into the correct branch circuit receptacle. (Refer to Voltage and Circuit Protection paragraph in the Installation section of this manual.)

On/Auto/Off Switch

Regulator

3.Open the drain valve fully (counter-clockwise) to permit air to escape and prevent air pressure build up in the air tank during the break-in period.

NOTE: Always drain tank on a washable surface or in a suitable container to prevent damaging or staining surfaces.

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 drain valve is open and there is minimal air pressure build-up in tank.
