Connect Air Line

You must install an air pressure regulator (F) on each gun air line to control air pressure to the gun. See FIG. 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 FIG. 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.

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.

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.

2.Connect each air hose (D) to a regulated air supply line (H).

Connect Fluid Hose

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 FIG. 9.

Install a fluid shutoff valve (M) to shut off the fluid supply to the gun. See FIG. 9.

Filter the fluid line of coarse particles and sediment to avoid clogging the fluid nozzle and causing fin- ishing defects.

1.Connect the fluid supply hose (J) to the gun fluid inlet (S) 1/4 npsm thread. See FIG. 10.

2.Connect the other end of the fluid hose (J) to a regu- lated fluid supply outlet (M). See FIG. 9.

3.In a circulating system, connect a grounded fluid return hose to the gun fluid outlet (T). See FIG. 10.

In a non-circulating system, remove the gun fluid outlet fitting (T) and plug the outlet port with the pipe plug supplied. See FIG. 10.
