Install the Air Line Accessories

1. Install an air line filter and an air and water separa-
tor 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. Install a bleed-type air shutoff valve (Q) on the
main air supply line to shut off all the air to the gun.
3. Install a bleed-type air regulator (M) on each of the
gun air supply lines to control the air pressure to
the gun. See Fig. 2, page 10.
4. Install a bleed-type air shutoff valve (L) on the fan
(C) and atomization (D) air lines to shut off the fan
and atomization air to the gun.
WARNING
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 bleed-type air shutoff
valve is required on the fan and atomization air
lines so trapped air will be relieved between the
valve and the gun after the valves are closed.
5. Install a check valve (S) in the pilot air line (R) to
prevent fluid from backing up into the air controls.

CAUTION
To avoid electrical breakdown damage to the fluid
regulator and other gun components, do not have
