Installation

Connect the Air Line

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

2.Install an air pressure regulator (L) on the gun air supply line to control the air pressure to the gun.

3.Install an air pressure regulator (D) on the pump air supply line to control air pressure to the pump.

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

WARNING

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

NOTE: The gun air inlet has a 1/4±18 npsm (R1/4±19) compound male thread that is compatible with NPSM and BSP female swivel connectors.

5.Install an air shutoff valve (X) on each gun air supply line, downstream of the gun air regulator, to shut off air to the gun(s).

6.Connect the air hose (K) from the air supply to the gun air inlet.

Connect the Fluid Line

WARNING

INJECTION HAZARD

To reduce the risk of property damage or serious injury, including fluid injection, which could be caused by component rupture or unrelieved fluid pressure,

DA fluid drain valve(s) (E) is required in your system to assist in relieving fluid pressure in the displacement pump, hose and gun; triggering the gun to relieve pressure may not be suffi- cient.

DA fluid pressure regulator (Q) must be installed in the system if the pump's maximum working pressure exceeds the gun's maximum fluid working pressure of 950 psi (66 bar).

1.Install a fluid filter (G) and drain valve(s) (E) close to the pump's fluid outlet. The drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun. See Fig. 1.

2.Install a fluid pressure regulator (Q) to control fluid pressure to the gun.

NOTE: Some applications require fine-tuned control of fluid pressure. You can control fluid pressure more accurately with a fluid pressure regulator than by regulating the air pressure to the pump.

3.Install a fluid shutoff valve (F) to shut off the fluid supply to the gun.

4.Install fluid drain valve(s) (E) close to the pump's fluid outlet.

NOTE: The gun fluid fitting (W) has a 1/4±18 npsm (R1/4±19) compound male thread that is compatible with NPSM and BSP female connectors.

5.Install an in-line fluid filter (N) on the gun fluid fitting (W) to avoid clogging the spray tip with particles from the fluid.

6.Connect the grounded fluid hose (H) to the gun fluid fitting (W) or optional in-line filter (N).
