Grounding
WARNING
FIRE AND EXPLOSION HAZARD
When pumping flammable fluids, this
leak detector must be grounded. Before
pumping, ground the system as ex-
plained below. Also read the section
FIRE OR EXPLOSION HAZARD on
page 3.
The polypropylene leak detectors are not
conductive. Attaching the ground wire to the lug
(15) grounds only the clamp (see Fig. 2). When
pumping conductive flammable fluids, always
ground the entire fluid system by making sure the
fluid has an electrical path to a true-earth ground.
To reduce the risk of static sparking, ground the leak
detector and all other equipment in the pumping area.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment.
Ground all of this equipment:
D Leak detector: Attach a ground wire to the
grounding lug (15) as shown in Fig. 2. Connect the
clamp end of the ground wire to a true earth
ground. To order a ground wire and clamp, order
Part No. 222011.
NOTE: To connect the ground wire to the leak
detector, first remove the copper connector from
the non-clamp end of the ground wire and discard
it, then push the bare wire through the grounding
lug on the leak detector.

D Fluid supply container: Follow your local code.
NOTE: When pumping conductive flammable
fluids, always ground the entire fluid system. See
the WARNING at left. Fig. 3 shows a
recommended method of grounding fluid containers
during filling. This is only a guide; contact your
Graco distributor for assistance in grounding your
system.
D Air compressor: Follow the manufacturer's
recommendations.
D Solvent pails used when flushing: Follow your local
code. Use only grounded metal pails, which are
conductive. Do not place the pail on a
non-conductive surface, such as paper or
cardboard, which interrupts the grounding
continuity.
