NOTE
Grounding of equipment is a means to provide a conductive path into the
ground so a static charge isn’t trapped on the surface of the equipment
where it could discharge as a spark.
Extreme care must be taken to prevent injury to fingers or hands when driv-
ing the ground rods. Do not place hands between the ram and drive collar.
Cloves should be worn. Be sure all connections are tight so as to avoid a
possible spark between the units and ground rod.
Drive Grounding Rod (12) into ground to the required depth. (see Table 2-1, Required depths
for grounding rods.) Grounding Rod (12) can be used as a nozzle hanger and/or a grounding
rod.
DEATH or serious injury may result if proper grounding procedures are not
followed prior to operating the equipment.
Remove Pumping Assembly (6) and Filter Separator (7) Grounding Rod (15) from Filter Sep-
arator— Frame. Drive Grounding Rod (15) into ground to the required depth. (See Table 2-1,
Required Depths For Grounding Rod.) Connect grounding cables (16) from Pumping As-
sembly (6) and Filter Separator (7) to grounding Rod (15). The Refueler and System are now
grounded and the fueling process may begin.
