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.

washer (X). Insert one end of the ground wire (Y)

Air and fluid hoses: Use only grounded hoses with
500 ft (150 m) maximum combined hose length to
ensure grounding continuity.
Air compressor: Follow manufacturer’s
recommendations.
Spray gun or dispensing valve: Connect to a
properly grounded fluid hose and pump.
Object being sprayed: Follow your local code.
Fluid supply container: 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 proper grounding continuity when
flushing or relieving pressure, always hold the metal
part of the spray gun firmly to the side of a
grounded metal pail, then trigger the gun.
