GETTING TO KNOW YOUR UNIT
Pressure Switch - Auto/Off Switch - In the auto position, the compressor shuts off automatically when tank
pressure reaches the maximum preset pressure. After air is used from the tank and drops to a preset low
level, the pressure switch automatically turns the motor back on. In the off position, the compressor will not
operate. This switch should be in the off position when connecting or disconnecting the power from the
unit.
When the pressure switch turns the motor off you will hear air leaking out of the pressure switch unloader
valve for a short time. This releases the air pressure from the discharge tube and allows the compressor to
restart easier.
ASME Safety Valve - This valve automatically releases air if the tank pressure exceeds the preset maximum.
Discharge Tube - This tube carries compressed air from the pump to the check valve. This tube becomes very
hot during use. To avoid the risk of severe burns, never touch the discharge tube.
Check Valve - One-way valve that allows air to enter the tank, but prevents air in the tank from flowing
back into the compressor pump.
Belt Guard - Covers the belt, motor pulley and flywheel.
Tank Drain Valve - This valve is located on the bottom of the tank. Use this valve to drain moisture from the
tank daily to reduce the risk of corrosion.
Tank Pressure Gauge - Indicates amount of air pressure stored in tank.
Air Filter - Keeps large particulates out of the air flowing into the compressor.
Breather - Vent for crankcase.
Oil Fill Port - Port used to refill the oil in the pump after oil changes or when oil is low.
Pump - Cast Iron 2-Stage air compressor pump that generates compressed air.
Motor - Power source that drives the pump to create compressed air.
Tank Outlet - This is where you plumb into to get compressed air from the pressure vessel. An isolation
valve should be installed here to be able to shut off the air supply from the tank.
INSTALLATION INSTRUCTIONS
Disconnect, tag and lock out power source then release all pressure from the system before
attempting to install, service, relocate or perform any maintenance.
Do not lift or move unit without appropriately rated equipment. Be sure the unit is securely
attached to lifting device used. Do not lift unit by holding onto tubes or coolers. Do not use unit
to lift other attached equipment.
Never use the wood shipping skids for mounting the compressor.
This compressor is not intended for outdoor installation.
Preparation
