Connect the Air Line

To reduce the risk of electric shock or other serious injury, the air supply hose must be electrically con- nected to a true earth ground. Use only Graco

Grounded Air Supply Hose.

1.Connect the Graco Grounded Air Supply Hose (R) between the air supply line and the gun's air inlet (V) (FIG. 2). The gun air inlet fitting has a left-hand thread. Connect the air supply hose ground wire (Q) to a true earth ground.

2.Install an air line filter/water separator (O) on the gun air line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the appearance of your finished workpiece and can cause the gun to malfunction.

3.Install a bleed-type air regulator (G) on the pump and gun air supply lines to control air pressure to the pump and gun.

4.Install a bleed-type air valve (E) on the pump air line to shut off air to the pump. Install an additional bleed-type air valve (C) on the main air line (A) to isolate the accessories for servicing.

The bleed-type air valve (E) is required in your sys- tem to relieve air trapped between the valve and the pump after the air regulator is shut off. Trapped air can cause the pump to cycle unexpectedly, which can result in serious injury, including splashing fluid in the eyes or on the skin.

Installation

5.Install an air shutoff valve (P) on each gun air supply line to shut off air to the gun(s).
