Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Static electricity is created by the high
velocity flow of fluid through the pump
and hose. If your system is not properly
grounded, sparking may occur and the
system may become hazardous.
To reduce the risk of static sparking
which can result in a fire or explosion
and cause serious injury, follow these
recommendations for providing electrical
continuity throughout your system.
Also read the WARNING section, FIRE
AND EXPLOSION HAZARD on page 2.
1. Pump: Loosen the grounding lug locknut (A) and
washer. Insert one end of a 12 ga (1.5 m
mum ground wire (B) into the slot in the lug (C).
Tighten the locknut securely. See Fig. 3. Connect
the other end of the ground wire to a true earth
ground. Order a Grounding Wire and Clamp, P/N
(

25 feet (7.6 m) long, 12 ga.)
2. Air and fluid hoses: Use only electrically conduc-
tive hoses with a maximum of 500 feet (150 m)
combined hose length to ensure grounding conti-
nuity.
3. Air compressor: follow the air compressor
manufacturer's recommendations.
Installation
4. Spray gun or dispensing valve: Obtain grounding
through connection to a properly grounded fluid
hose and pump.
5. Fluid supply container: according to your local
code.
6. Object being sprayed: according to local code.
7. All solvent pails used when flushing, according to
local code. Use only metal pails which are con-
ductive, placed on a positively grounded surface.
Do not place the pail on a non–conductive 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
gun or dispensing valve firmly to the side of a
grounded metal pail, then trigger the gun.
