Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the

system as explained below. Also read

the section FIRE AND EXPLOSION

HAZARD on page 4.

1. Pump: loosen the grounding lug locknut (W) and

washer (X). Insert one end of a 12 ga (1.5 mm2)

minimum ground wire (Y) into the slot in lug (Z)

and tighten the locknut securely. See Fig. 1. Con-

nect the other end of the wire to a true earth

ground. Order Part No. 237569, Ground Wire and

Clamp.

2. Air and fluid hoses: use only electrically conductive

hoses with a maximum of 500 ft (150 m) combined

hose length to ensure grounding continuity.

3. Air compressor: follow manufacturer’s recommen-

dations.

4. Spray gun: grounding is obtained through connec-

tion to a properly grounded fluid hose and pump.

5. Object being sprayed: according to your local

code.

6. Fluid supply container: according to your local

code.

7. All solvent pails used when flushing, according to

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.

8. To maintain grounding continuity when flushing or

relieving pressure, always hold a metal part of the

spray gun firmly to the side of a grounded metal

pail, then trigger the gun.
