Installation/Operation

CAUTION

The Premier air motor is designed for intermittent duty cycle applications, such as spraying of corrosion control materials, or adhesive and sealant applica- tions. It is not recommended for continuous duty circulating systems. Contact your Graco distributor for further application information.

NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawings.

NOTE: Always use Genuine Graco Parts and Acces- sories, available from your Graco distributor. If you supply your own accessories, be sure they are ade- quately sized and pressure rated for your system.

System Accessories

WARNING

A bleed-type master air valve and a fluid drain valve are required in your system. These accesso- ries help reduce the risk of serious injury, including fluid injection and splashing of fluid in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

The bleed-type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump.

The fluid drain valve assists in relieving fluid pres- sure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient.

Mounting Accessories

Mount the motor to suit the type of installation planned. Motor dimensions and the mounting hole layout are shown on page 27.

If you are mounting the motor on an elevator or a cart, refer to the separate manuals supplied with those components for installation and operation instructions.

Air Line Accessories

The following air line accessories are available from Graco. Contact your Graco distributor for help in designing a system to suit your particular needs.

DA bleed-type master air valve is required in your

system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING

at left). Be sure the bleed valve is easily accessible from the motor, and is located downstream from the air regulator. Order Part No. 113163.

DAn air regulator controls pump speed and outlet

pressure by adjusting the air pressure to the motor. Locate the regulator close to the motor, but up- stream from the bleed-type master air valve.

DAn air line filter removes harmful dirt and moisture from the compressed air supply.

DAn air line lubricator adds oil to the compressed air supply at an adjustable rate, to automatically lubricate the air motor.

DA pump runaway valve senses when the pump is running too fast and automatically shuts off the air to the motor. A pump which runs too fast can be seriously damaged. Install closest to the motor air inlet.
