Grounding the System
WARNING
FIRE AND EXPLOSION HAZARD Before operating the fluid pressure regulator, ground the system as explained below.
Pump: Use a ground wire and clamp. Loosen the grounding lug locknut (W) and washer (X). Insert one end of a 1.5 mm@ (12 ga) minimum ground wire (Y) into the slot in lug (Z) and tighten the locknut securely. Connect the other end of the wire to a true earth ground. Order Part 237569 Ground Wire and Clamp.

Heaters, if used: See the heater instruction manual.
Air compressor: Follow manufacturer’s recommendations.
Spray gun: Ground through connection to a properly grounded fluid hose and pump.
Fluid supply container: Follow your local code.
Object being sprayed: Follow your local code.
Solvent pails used when flushing: Follow your local code. Use only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.
To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the spray gun firmly to the side of a grounded metal pail, then trigger the gun.
