Pump:
use a ground wire and clamp (Y). See F
IG
. 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 nonconductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.

Ensure the wall is strong enough to support the
weight of the pump assembly and accessories, fluid,
hoses, and stress caused during pump operation.

Connect air and fluid hoses.
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical current
due to static build up or in the event of a short circuit.
