INSTALLATION 
Check the Electrical Grounding
WARNING
Proper electrical grounding of every part of your system is essential. For your safety, read the warn- ing section, FIRE OR EXPLOSION HAZARD, on page 5. Ground the system as explained there. Then check your system as explained below.
1.Shut off all air lines to the gun.
2.Shut off the fluid supply to the gun.
3.Have a qualified electrician check the electrical grounding continuity of the spray gun and air hose.
a.With the electrically conductive air hose (BB) connected and properly grounded, use a megohmmeter (AA) (shown in ACCESSORIES section) to measure the resistance between the gun body (Y) and a true earth ground (Z). Use an applied voltage of 500 volts minimum to 1000 volts maximum. See Fig 1.
b.If the resistance is greater than 2 megohms, check the tightness of the ground connections, 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.
Installing Optional Remote Fan Air Adapter
NOTE: See ACCESSORIES to order the Remote Fan Air Adapter 181±053 and 90_ Elbow 108±234.
1.Place a wrench on the flats of the valve housing (55) and remove the fan air valve assembly from the gun body (1). See Fig 20, page 23.
