Installation
The pump is designed to supply hydraulic oil to the
accumulators in an oil rig blow-out prevention system.
The Typical Installation shown in F
IG
. 1, page 4 is only a
guide. Contact your Graco representative for assistance
in designing a system to meet your needs.

Grounding
The following instructions refer to F
IG
. 2.
To ground the pump:
1. Loosen the grounding lug locknut (N) and washer
(P).
2. Insert one end of a 12 gauge (1.5 mm
2
) minimum
ground wire (R) into the slot in lug (S) and tighten
the locknut securely.
3. Connect the other end of the wire to a true earth
ground such as a steel building column or water
pipe. Check local code.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
• Proper hose and plumbing line grounding
continuity is essential to maintaining a grounded
system. Check the electrical resistance of your air
and fluid hoses or plumbing line at least once a
week.
• If you hose does not have a tag on it which
specifies the maximum electrical resistance,
contact the hose supplier or manufacturer for the
maximum resistance limits.
• Use a resistance meter in the appropriate range
for your hose to check the resistance. If the
resistance exceeds the recommended limits,
replace it immediately.
• An ungrounded or poorly grounded hose or
plumbing line can make your system hazardous.
