Installation and Operation 7
Mounting the Pump
Select a location that allows the operator easy
access to the pump and air controls, sufficient room
to change supply containers, and a secure mount-
ing platform.
If you are mounting the pump directly on the supply
container, be sure it is positioned so the pump’s
intake tube is no more than 1 in. (25 mm) from the
bottom of the container. Mount the pump to the
cover or other suitable mounting device.
Grounding
Proper grounding is essential to maintaining a safe sys-
tem.
To reduce the risk of static sparking, ground the pump.
Check local electrical codes for detailed grounding
instructions for your area and equipment type. Be sure
the following equipment is properly grounded:
Pump: See F
IG. 2
Air and Fluid hoses: Use only electrically conductive
hoses.
Air compressor: Follow manufacturer’s recommen-
dations.
Dispensing valve: Obtain grounding through con-
nection to a properly grounded fluid hose and pump.
Fluid supply container: Follow your local code.
Object being lubricated: Follow your local code.
Any pails used when flushing: Use only metal,
grounded pails when flushing. Make firm
metal-to-metal contact between a metal part of the
dispensing valve and the pail. Use the lowest possi-
ble pressure.
To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
dispensing valve firmly to the side of a metal pail
and then open the dispensing valve.
To maintain grounding continuity when flushing or reliev-
ing 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, remove the ground screw (Z) and
insert through the eye of the ring terminal at end of
ground wire, (Y). Fasten the ground screw back onto the
pump and tighten securely. Connect the other end of the
ground wire to a true earth ground. See F
IG. 2. To order
a ground wire and clamp order Part No. 222011.

ing operation. Failure to do so could result in personal
injury or equipment damage.

ment from the bottom of the container before
