Air Supply Line
1. See Fig. 12. Install an air line filter/water
separator (M) on the main air supply 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.
2. The WB3000 system includes a bleed-type air
regulator (N) on the gun air supply line (P), to
control air pressure to the gun.
To reduce the risk of electric shock or other
serious injury, you must use the red-colored
Graco Electrically Conductive Air Hose for the
gun air supply, and you must connect the hose
ground wire to a true earth ground. Do not use
the black or gray-colored Graco air hoses.
3. Connect the red-colored Graco Electrically
Conductive Air Hose (P) between the gun air
regulator (N) and the gun’s air inlet. The gun air
inlet fitting has a left-hand thread. Connect the
air supply hose ground wire (Q) to a true earth
ground.
Trapped air can cause the fluid supply unit to
cycle unexpectedly, which can result in serious
injury, including splashing fluid in the eyes or
on the skin. Do not operate the equipment
without the bleed-type air valve (B) installed.
4. The WB3000 system includes a bleed-type air
valve (B). The bleed-type air valve is required
to shut off all air to the system and relieve air
trapped between the valve and the fluid supply
unit after the air regulator is shut off. Connect the
main air supply line (A) to the bleed valve.
5. Install an additional bleed-type air valve (CC)
upstream of the air filter (M) to isolate the filter
for servicing.
Ground the Cabinet
Connect the main ground wire (V) to a true earth
ground.
