You know that the cooling system is working when air is being expelled.
Air Compressor Pump (not shown): Compresses air into the air tank. Working
air is not available until the compressor has raised the air tank pressure above that
required at the air outlet.
Drain Valve: The drain valve is located at the base of the
Drain
Valve
air 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
the air tank. When the air compressor reaches "cut-out"
pressure, the check valve "closes", allowing air
Check Valve
pressure to remain inside the air tank.
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.
HOW TO USE YOUR UNIT
How to Stop
1. Set the On/Off switch to "Off".
Before Starting
Do not operate this unit until you read and understand this
instruction manual for safety, operation and maintenance instructions.
Break-in Procedure
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/Off switch 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 pre-
vent air pressure build up in the air tank during the break-in period.
4. Move the On/Off switch to "On" 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.
Before Each Start-Up
1. Set the On/Off switch to "Off".
2. Turn the regulator knob counter-clockwise to set the outlet pressure to zero.
3. Attach hose and accessories.
Risk of unsafe operation. Firmly grasp air hose in hand when
installing or disconnecting to prevent hose whip.
Risk of unsafe operation. Do not use damaged or worn
