Ventilate the Spray Booth

WARNING

Flammable or Toxic Vapor Hazard

Provide fresh air ventilation to avoid the buildup of flammable or toxic vapors. Do not operate the gun unless ventilation fans are operating.

Check and follow all National, State, and Local codes regarding air exhaust velocity requirements.

High velocity air exhaust will decrease the operating effi- ciency of the electrostatic system. The minimum allow- able air exhaust velocity is 60 linear ft/min (18.3 linear meters/minute).

Connect the Air Line

WARNING

Electric Shock Hazard

To reduce the risk of electric shock or other serious injury, you must use the red-colored Graco Electrically Conductive Air Hose for the gun air supply hose, and you must con-

nect the hose ground wire to a true earth ground. Do not use the black or grey-colored Graco air hoses.

1.Install an air line filter/water separator (M) on the main air supply line to ensure a dry, clean air supply to the gun. Dirt and moisture can ruin the appear- ance of your finished workpiece and can cause the gun to malfunction.

2.Install a bleed-type air regulator (N) on the gun air line (P).

3.Connect the red-colored Graco Grounded Air Sup- ply Hose (P) between the gun air regulator (N) and the gun's air inlet. The gun air inlet fitting has a left-hand thread. Connect the air supply hose ground wire (Q) to a true earth ground.

Installation

4.Connect the main air supply line (A) to the bleed-type air valve (B). The bleed valve shuts off all air to the system. Install an additional bleed-type air valve (B) upstream of the air filter (M) to isolate the filter for servicing.

WARNING

Pressurized Equipment Hazard

The bleed-type air valve (B) is required in your system to relieve air trapped between

the valve and the fluid supply unit after the air regulator (D) is shut off. Trapped air can cause the fluid supply unit to cycle unexpectedly, which can result in serious injury, including splashing fluid in the eyes or on the skin.

Ground the Cabinet

Connect the main ground wire (V) to a true earth ground.

Connect the Waterborne Fluid Hose

Always use a Graco waterborne fluid hose between the voltage isolation system fluid outlet and the gun fluid inlet. See FIG. 3.. The waterborne fluid hose (101) con- sists of an inner PTFE tube (T) and an abrasion-resis- tant outer jacket (J). Shielded hose 245252 also has a conductive layer (C), The conductive layer is connected to ground at the gun fitting bracket (104).

Before connecting the waterborne fluid hose to the gun, blow it out with air and flush with water to remove con- taminants. Flush the gun before using it.

WARNING

Electric Shock Hazard

To reduce the risk of electric shock, install only one continuous Graco waterborne hose between the isolated fluid supply and the gun. Do not splice hoses together.
