Setup
Connect Air Line
1. For manifolds with a separate ATOM and FAN port,
the gun cylinder, fan, and atomization air must be
supplied and regulated separately. For the manual
fan valve manifold, only one supply line is required
for both atomization and fan air.
2. Connect each air hose (D) to a regulated air supply
line (H).
Connect Fluid Hose
1. Connect the fluid supply hose (J) to the gun fluid
inlet (S) 1/4 npsm thread. See F
IG . 10.
2. Connect the other end of the fluid hose (J) to a regu-
lated fluid supply outlet (M). See F
IG . 9.
3. In a circulating system, connect a grounded fluid
return hose to the gun fluid outlet (T). See F
IG . 10.
In a non-circulating system, remove the gun fluid
outlet fitting (T) and plug the outlet port with the pipe
plug supplied. See F
IG . 10.
You must install an air pressure regulator (F) on
each gun air line to control air pressure to the gun.
See F
IG . 8.
If your regulated air source does not have a filter,
install an air filter (G) on each air line to ensure a
dry, clean air supply to the gun. Dirt and moisture
can ruin the appearance of your finished work-
piece. See F
IG . 8.
Install a bleed type air shutoff valve (E) on each
gun air supply line, downstream of the gun air regu-
lator, to shut off air to the gun.
The gun atomizing and fan air inlets are 3/8 in. O.D.
tubing. The cylinder air inlet accepts 1/4 in. (6.3
mm) O.D. tubing. Use 3/8 in. (9.5 mm) O.D. tubing
for fan and atomization air to minimize excessive
pressure drop in the hoses.

Before connecting the fluid line, blow it out with air
and flush it with solvent. Use solvent that is compat-
ible with the fluid to be sprayed.
Install a fluid regulator (L) on the fluid line to control
fluid pressure to the gun. See F
IG . 9.
Install a fluid shutoff valve (M) to shut off the fluid
supply to the gun. See F
IG . 9.
Filter the fluid line of coarse particles and sediment
to avoid clogging the fluid nozzle and causing fin-
ishing defects.
