Connect the Air Line
1. Connect the Graco Grounded Air Supply Hose (R)
between the air supply line and the gun's air inlet (V)
(F
IG. 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.
5. Install an air shutoff valve (P) on each gun air supply
line to shut off air to the gun(s).
Connect the Charging Probe
1. Apply dielectric grease to probe socket.
2. Press electrode on in Connect/Disconnect position
shown in F
IG. 4.
3. Rotate electrode to spray position.

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.

IG. 2
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.
