Installation

Connect the Fluid Line

Filter the Fluid

1.Before connecting the fluid line (N), blow it out with air and flush it with solvent. Use solvent which is compatible with the fluid to be sprayed.

2.Install a fluid regulator (M) on the fluid line to con- trol fluid pressure to the gun.

WARNING

Fluid Injection Hazard

The fluid drain valve (U) 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 sufficient. Install a drain valve close to the pump's fluid outlet. The drain valve reduces the risk of serious injury, including fluid injection and splash- ing in the eyes or on the skin.

3.Install a drain valve (U) near the pump outlet.

4.Connect the fluid line to the 1/4 npsm gun fluid inlet (W).

5.Before running any paint through the spray gun, flush it out with a compatible solvent.

Install a fluid filter (K) at the pump outlet to remove particles and sediment which could clog the spray tip.

The gun includes an inline fluid filter (1) for additional filtration.

Select a Spray Tip

WARNING

Fluid Injection Hazard

To reduce the risk of a fluid injection injury, always follow the “Pressure Relief Proce- dure”, page 25, before removing or install- ing the spray tip, air cap, or tip guard.

The fluid output and pattern width depend on the size of the spray tip, the fluid viscosity, and the fluid pres- sure. Use the “Spray Tip Selection Chart”, page 48, as a guide for selecting the appropriate spray tip for your application.

Refer to the gun operation manual to install the spray tip.
