HAZARDOUS FLUIDS
To reduce the risk of serious injury,
splashing in the eyes or on the skin, and
toxic fluid spills,
never
move or lift a
pump under pressure. If dropped, the fluid section
may rupture. Always follow the
Pressure Relief
Procedure Warning
on page 9 before moving or
lifting the pump.
WARNING
D
The pump is very heavy. If it must be moved, have
two people lift the pump by grasping the outlet
manifold (103) securely. See Fig. 3 on page 7.
Tightening Screws Before First Use
After you unpack the pump, and before you use it for
the first time, check and retorque external fasteners.
Retorque the fluid cover screws first, then the manifold
screws. This keeps the manifolds from interfering with
tightening the fluid covers. See the
Service
section for
torque specifications.
After the first day of operation, check and retorque the
fasteners again. Although the recommended
frequency for retorquing fasteners varies with pump
usage, a general guideline is to retorque fasteners
every two months.
Grounding
FIRE AND EXPLOSION HAZARD
This pump must be grounded. Before
operating the pump, ground the system
as explained below. Also, read the
section
FIRE AND EXPLOSION
HAZARD,
on page 3.
WARNING
To reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of equip-
ment.
Ground all of this equipment:
D
Pump
: Connect a ground wire and clamp as shown
in Fig. 1. Loosen the grounding screw (W). Insert
one end of a 12 ga (1.5 mm
@
) minimum ground wire
(Y) behind the grounding screw and tighten the
screw securely. Connect the clamp end of the
ground wire to a true earth ground. Order Part No.

Air and fluid hoses
: Use only grounded hoses with
a maximum of 500 ft (150 m) combined hose
length to ensure grounding continuity.
D
Air compressor
: Follow the manufacturer’s recom-
mendations.
D
All solvent pails used when flushing:
Follow the
local code. Use only metal pails, which are conduc-
tive. Do not place the pail on a non-conductive
surface, such as paper or cardboard, which inter-
rupts the grounding continuity.
D
Fluid supply container:
Follow the local code.
