Grounding
Pump:
use a ground wire and clamp. See F
IG
. 1.
Loosen the locknut (W) of the grounding lug (Z). Insert
one end of the wire (Y) in the ground 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.
Hydraulic power supply:
follow manufacturer’s recom-
mendations.
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.
To maintain grounding continuity when flushing or
relieving pressure:
hold metal part of the spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
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.
