INSTALLATION

WARNING

Installing and servicing this equipment requires access to parts which may cause electrostatic shock or other serious bodily injury if work is not performed properly.

DDo not install or service this equipment unless you are trained and qualified.

DBe sure your installation complies with National, State and Local codes for the installation of elec- trical apparatus in a Class
, Group D Hazardous Location.

DCheck and follow all local safety and fire codes, NFPA 33, NEC 504 and 516, and OSHA standard 1910.107.

Ventilate the Spray Booth

WARNING

To prevent hazardous concentrations of toxic and/or flammable vapors, spray only in a properly venti- lated spray booth. Never operate the spray gun unless ventilation fans are operating.

Electrically interlock the gun air supply with the ventila- tors to prevent gun operation without ventilating fans op- erating. 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 feet/minute (19 linear meters/minute).

Install the Gun Mounting Bracket

Attach the mounting bracket to the robot or reciprocator. See the ACCESSORIES section for the mounting brack- et and mount extension options and refer to Fig 3 and Fig 4 for mounting positions.

Install the Gun and Manifold (See Fig 5 )

1.Remove the air cap nut/air cap assembly and slide the shroud off the gun.

2.Connect the gun to the manifold by tightening the three socket head cap screws; use the ball end wrench (46), supplied. Make sure the o-ring is in place on the manifold.

3.Slide the gun and manifold along the dovetail until the

button head screw bottoms against the mounting bracket.

4.Secure the gun to the mounting bracket with the but- ton head screw , using the ball end wrench (46). Tighten the two mounting bracket setscrews.

5.Slide the shroud onto the gun and secure it by tight- ening the air cap nut onto the gun barrel. Tighten the nut just enough so that the air cap is snug but can still be turned.

Connect the Air, Fluid, and Optional Fiber Optic Lines (See Fig 6 )

WARNING

To reduce the risk of electrostatic shock or other serious injury, the turbine air supply hose must be electrically connected to a true earth ground. Use

Only Graco Electrically Conductive Air Supply Hose and connect the hose ground wire to a true earth ground.

See the ACCESSORIES section to order Graco Electri- cally Conductive Air Supply Hose. This hose and the gun have special left-hand threads to prevent connecting another type of air supply hose to the gun turbine air inlet.

Connect the air, fluid, and optional fiber optic lines to the gun manifold as shown in Fig 6 . Before connecting the fluid line, blow it out with air and flush it with solvent. Use solvent that is compatible with the fluid being sprayed.
