INSTALLATION

Mount the Gun

Mount the gun on a stationary support or on a reciprocat- ing arm. The mounting rod must be properly grounded.

Mount the gun so the front of the gun is 254 to 300 mm (10 to 12 in.) from the work piece.

Connect the Air Line (Refer to the Typical Installation Drawing)

WARNING

To reduce the risk of electric shock or other serious bodily injury, the air supply hose must be electrically connected to a true earth ground. Use Only Graco Electrically Conductive Air Supply Hose. This hose, and the gun, have special threads which pre- vent using any other type of hose with the gun. See the ACCESSORIES section to order the hose.

1.Install an air line filter (K) and an air and water sepa- rator (B) on the main air line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the ap- pearance of your finished workpiece and can cause the gun to malfunction.

2.Install an air line lubricator (D) close to the pump air inlet.

3.Install a normally closed, 3-way air solenoid (P) or manual valve on the turbine, cylinder and remote fan air supply lines. (The remote fan line is optional.)

4.Install a bleed-type air regulator (E) on the pump, turbine, atomizing, cylinder, and remote fan (option- al) air supply lines to control air pressure to the pump and gun.

5.Install a bleed-type air shutoff valve (A) on the main air line, the pump line, and each gun air supply line to shut off air to the pump and gun.

WARNING

The bleed±type air shutoff valve (A) 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 unexpectedly, which could result in serious bodily injury, including splashing in the eyes or on the skin and injury from moving parts.

6.Connect the cylinder air line to the gun's cylinder air inlet (marked CYL).

7.Connect the atomizing air line to the gun's atomizing air inlet (marked ATOM).

8.Connect the turbine air supply line to the gun's air in- let (marked ES). The gun air inlet fitting has a left hand thread. Connect the air supply hose ground wire to a true earth ground.

9.A remote fan air adapter is available to control the fan air at the control booth. See Installing the Optional Remote Fan Air Adapter, on page 8.

Connect the Fluid Line (Refer to the Typical Installation Drawing)

1.Before connecting the fluid line, blow it out with air and flush it with solvent. Use solvent which is com- patible with the fluid to be sprayed.

2.Install a fluid regulator (L) on the fluid line to control fluid pressure to the gun.

3.Install a fluid filter (G) and drain valve (H) at the pump outlet.

WARNING

The fluid drain valve (H) is required in your system to assist in relieving fluid pressure in the displace- ment pump, hose and gun; triggering the gun to relieve pressure may not be sufficient. Install a drain valve close to pump's fluid outlet. The drain valve reduces the risk of property damage or seri- ous bodily injury, including splashing in the eyes or on skin and contamination from hazardous fluids.

4. Connect the fluid line to the gun fluid inlet.

CAUTION

Do not use metal fittings at the gun barrel. For cir- culation systems, use plastic fittings.
