Pressure Release Valve

Drain Valve: The
drain valve is located		Drain
at the base of the air
		Valve
tank and is used to
drain condensation at
the end of each use.
Check Valve: When the air
compressor is
operating, the
check valve
is "open",
allowing
compressed
air to enter	Check Valve
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 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 after the unit reaches "cut-out" pressure.

Motor Overload Protector (not shown): The motor has an automatic reset thermal overload protector. If the motor overheats for any reason, the overload protector will shut

Off the motor. The motor must be allowed to cool down before restarting. The compressor will automatically restart after the motor cools.

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 First Start Up

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

3.Open the drain valve (counter- clockwise) 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 drain valve is open and there is minimal air pressure build-up in tank.

6.After 15 minutes, close the drain valve by turning clockwise. The air receiver will fill to "cut-out" pressure and the motor will stop.

The compressor is now ready for use.
