Installation
Grounding
Pump: use ground wire and clamp (supplied). Loosen
grounding lug locknut (W) and washer (V). Insert one
end of a 12 ga (1.5 mm
2
) minimum ground wire (Y) into
the slot in lug (Z) and tighten the locknut securely. Con-
nect the other end of the wire to a true earth ground.
Order Part No. 237569 Ground Wire and Clamp.
Hydraulic Hoses and Fluid Outlet Hoses: use only
electrically conductive hoses.
Hydraulic Power Supply and Air Compressor: follow
manufacturer’s recommendations.
Any pails used when flushing: use only metal
grounded pails when flushing. Make firm metal-to-metal
contact between a metal part of the dispense valve and
the pail. Use the lowest possible pressure.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
