INSTALLATION

Check the Electrical Grounding (See Fig 7 )

WARNING

Proper electrical grounding of every part of your system is essential. For your safety , read the warning section, FIRE, EXPLOSION, OR ELECTROSTATIC SHOCK HAZARD , on page

3.Ground the system as explained there. Then check your system as explained below.

1.Completely turn off the air and fluid supplies to the gun.

2.Have a qualified electrician check the electrical grounding continuity of the spray gun and air hose.

a.With the electrically conductive air hose con- nected and properly grounded, use a

megohmmeter to measure the resistance between the gun manifold and a true earth ground. Use an applied voltage of 500 minimum to 1000 volts maximum.

and be sure the air supply hose ground wire is connected to a true earth ground. If the resis- tance is still greater than 2 megohms*, replace the air supply hose.

*If you are using the red colored hose, resis- tance should not exceed 100 ohms.

Install the Fabric Cover (See Fig 8 )

1.Install a fabric cover over the front of the gun and slide it back to cover the exposed tubing and hoses at the back of the manifold. See ACCESSORIES sec- tion.

2.Cut a small slit in the cover and route the two exhaust tubes outside the robot arm or reciprocator. This en- ables you to monitor the exhaust tubes for the pres- ence of any paint or solvent. See Check for Fluid Leakage on page 12. Strap down the exhaust tubes to prevent them from moving around.
