To reduce the risk of electric shock or other serious
injury, you must:
• Use the electrically conductive red-colored
Graco Grounded Air Hose for the gun air supply.
• Do not use the black or gray-colored Graco air
hoses.
• Connect the hose ground wire to a true earth
ground.
1.
Install an air line filter/water separator (AS) on
the main air supply line to ensure a dry, clean air
supply to the gun.
Note
Dirt and moisture can ruin the
appearance of your finished workpiece
and can cause the gun to malfunction.

.
2.
Install a bleed type air shut-off valve (AB) and
air regulator (PR) on the gun air supply line to
control air pressure to the gun.
3.
Connect the red-colored Graco Electrically
Conductive Air Hose (HG) between the gun air
regulator (PR) and the gun’s air inlet. The gun
air inlet fitting has a left-hand thread. Connect
the air supply hose ground wire (GND) to a true
earth ground.
Note
Some isolation systems provide controls
to regulate the air to the spray gun.
Consult the isolation system manual for
proper installation.
