Installation
Grounding
Pump:
use a ground wire and clamp (Y). See F
. 1.
Loosen the grounding lug locknut (W) and washer.
Insert one end of the ground wire into the slot in the lug
and tighten the locknut securely. Connect the ground
clamp to a true earth ground. Order Part No. 237569,
Ground Wire and Clamp.
Air and fluid hoses:
use only electrically conductive
hoses
with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check the
electrical resistance of hoses. If total resistance to
ground exceeds 25 megohms, replace hose immedi-
ately.
Air compressor:
follow manufacturer’s recommenda-
tions.
Surge tank:
use a ground wire and clamp.
Dispense valve:
ground through a connection to a
properly grounded fluid hose and pump.
Fluid supply container:
follow local code.
Object being sprayed:
follow local code.
Solvent pails used when flushing:
follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a non-conductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure:
hold metal part of the spray gun or
valve firmly to the side of a grounded metal pail, then
trigger the gun or open the valve.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
