Haier 309292L Connect the Fluid Line, Filter the Fluid, Select a Fluid Nozzle and Air Cap

Installation

Connect the Fluid Line

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 control fluid pressure to the gun.

3.Install a fluid filter (K) and drain valve (U) at the pump outlet.

WARNING

Pressurized Equipment 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 splashing in the eyes or on the skin.

4.Connect the fluid line to the 3/8 npsm gun fluid inlet

(W).

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

WARNING

Pressurized Equipment Hazard

To reduce the risk of an injury, follow the Pressure Relief Procedure on page 24 before removing or installing a fluid nozzle and/or air cap.

Filter the Fluid

Install a fluid filter (K) to remove particles and sediment which could clog the spray nozzle.

Select a Fluid Nozzle and Air Cap

The gun is supplied with Part No. 197266 Nozzle and 197477 Air Cap. If you require a different size, refer to Table 1 and Table 2 , and instruction manual 309419, or consult with your Graco distributor. See Air Cap/Nozzle Replacement on page 26.
