Grounding
Proper grounding is an essential part of maintaining a
safe system.
To reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment.
Ground all of this equipment:
D Pump: Use a ground wire and clamp as shown
in Fig. 1.
D Air and fluid hoses: Use only electrically conductive
hoses.
D Air compressor: Follow the manufacturer’s
recommendations.
D Fluid supply container: Follow the local code.
D To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
valve firmly to the side of a grounded metal pail,
then trigger the valve.
To ground the pump, loosen the grounding lug locknut
(W) and washer (X). Insert one end of a 12 ga (1.5
mm@) minimum ground wire (Y) into the slot in lug (Z),
and tighten the locknut securely. Connect the other
end of the wire to a true earth ground. To order a
ground wire and clamp, order Part No. 222011.

Mounting
WARNING
Mount the pump securely so that it cannot move
around during operation. Failure to do so could
result in personal injury or equipment damage.
1. Plan the mounting layout for easy operator access
to the pump air controls, sufficient room to change
drums and a secure mounting platform.
2. If using a follow plate (H), remove the drum cover.
Scoop the material to the center of the drum to
make the surface concave. Place the plate on the
material. Guide the pump foot valve through the
plate.
3. Mount the pump to the drum cover or other
suitable mounting device.
4. For ease in changing drums, install a pump
elevator.
