Grounding
This 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.

Pump: Loosen the ground screw and attach a
ground wire. Tighten the ground screw securely.
Connect the other end of the ground wire to a
true earth ground.
NOTE:
NOTE:
NOTE: Both pumps are connected to a common
control module and must be grounded to the
same ground point. Different ground points
(unequal potential) may cause current to flow
through component cables, causing incorrect
signals.

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 immediately

Before using the equipment, open the fill cap (P) and
add Graco Part No. 16W645 ISO 220 silicone-free
synthetic gear oil. Check the oil level in the sight glass
(K). Fill until the oil level is near the halfway point of
the sight glass. The oil capacity is approximately 1.5
