Installation

Connect Air Line

1.Install an air/water separator and an air line filter to ensure a clean, dry air supply to the gun. Dirt and moisture in the line can ruin the appearance of your finished piece.

2.Install an air pressure regulator on each gun air sup- ply line.

3.For manifolds with separate fan and atomization ports, the gun cylinder, fan, and atomization air must be supplied and regulated separately. For manual valve manifolds, only one supply line is required for both atomization and fan air.

A minimum of 50 psi (0.34 MPa, 3.4 bar) air pres- sure must be supplied to the cylinder for proper operation. Set the atomization air as needed for complete atomization of the entire pattern. The tip size is the primary controller of the pattern size. Use the fan air only as needed to slightly adjust the pattern size.

4.Install a bleed-type master air shutoff valve on the main air line. Install an additional bleed-type valve on each pump air supply line, downstream of the pump air regulator, to relieve air trapped between this valve and the pump after the air regulator is shut off.

The bleed-type air shutoff valve is required in your sys- tem to relieve air trapped between this valve and the pump after the air regulator is closed. Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury.

5.Install a bleed-type air shutoff valve on each gun air supply line, downstream of the gun air regulator, to shut off air to the gun.

6.For manifolds with separate fan and atomization ports, connect a separate air supply line to the gun atomizing air inlet (D) and cylinder air inlet (C). Con- nect an air supply line to the fan air inlet (E) if desired. See FIG. 6. For manifolds with a manual fan valve, only one supply line is required for both atom- ization and fan air.

The gun atomizing and fan air inlets are 3/8 in. (9.5 mm) O.D. tubing compatible. The cylinder air inlet accepts 1/4 in. (6.3 mm) O.D. tubing.
