Installation
Install the Air Line Accessories
Install a bleed-type master air valve (X) on the main air
supply line (W) to shut off all the air to the gun. See
Fig. 1, page 8.
To ensure a dry, clean air supply to the gun, install an
air line filter and an air and water separator on the air
lines. Dirt and moisture can ruin the appearance of
your finished workpiece and can cause the gun to mal-
function.
Install an air regulator (M) on each of the air supply
lines (B, C, D, E, Y) to control the air pressure to the
gun.
Install a solenoid valve (K) on the fan and atomization
air lines (C, D) to actuate the gun and shut off the fan
and atomization air to the gun. The solenoid valves
must have a quick exhaust port.
PRESSURIZED EQUIPMENT HAZARD
Trapped air can cause the gun to spray
unexpectedly, which could result in a
serious injury, including splashing in the
eyes or on the skin. The solenoid valves (K) must
have a quick-exhaust port so trapped air will be
relieved between the valve and the gun when the
solenoids are shut off.
WARNING

bolts (103) and slide the mounting bracket onto a
