Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE OR EXPLOSION HAZ-
ARD on page 4.
D Pump: Use a ground wire and clamp as shown in
Fig. 1. Loosen the grounding lug locknut (W) and
washer (X). Insert one end of a 12 ga (1.5 mm@)
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 num-
ber 237569 Grounding Clamp and Wire.
D Fluid and hydraulic hoses: Use only grounded
hoses with a maximum of 500 ft (150 m) combined
hose length to ensure grounding continuity.
D Hydraulic Power Supply: Follow the manufacturer’s
recommendations.
D Spray gun: Ground through connection to a prop-
erly grounded fluid hose and sprayer.
D Object being sprayed: Follow the local code.
D Fluid supply container: Follow the local code.
D Solvent pails used when flushing: Follow the 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 continu-
ity.
D 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.
