WARNING

TOXIC FLUID HAZARD
To prevent hazardous concentrations of
toxic and/or flammable vapors, spray
only in a properly ventilated spray booth.

Never operate the spray gun unless ventilation
fans are operating.

Check and follow all of the national, state and local
codes regarding air exhaust velocity requirements.

Check and follow all local safety and fire codes.

Installation Procedure

NOTE: See Accessories section for information on
recommended accessories.

1.

Install an air filter (G) in the gun air supply line to
ensure a clean dry air supply to the gun. See
Fig. 1. Dirt and moisture in the air line can affect
the appearance of your finished workpiece.

2.

Install an air regulator (F) downstream from the air
filter to control atomizing air pressure to the gun.

3.

Install an air shut-off valve (E).

4.

Connect the atomizing air hose (D) to the 1/4 npsm
air inlet (C) of the gun.

5.

Connect the fluid supply hose, siphon cup gravity
cup (see Fig.  2) to the 3/8 npsm fluid inlet (B) of
the gun.

NOTE: If you use a fluid supply line, install a fluid regu-
lator in the gun fluid supply line to control fluid pressure
to the gun.
