Installation
Grounding
Pump:
use ground wire and clamp (supplied). Remove
the ground screw (Z) and insert through eye of ring
terminal at the end of ground wire (Y). Fasten ground
screw back onto pump and tighten securely. Connect
the other end of the wire to a true earth ground. Order
Part 222011 Ground Wire and Clamp.
Air and fluid hoses:
use only electrically conductive
hoses.
Air compressor:
follow manufacturer’s
recommendations.
Dispense valve:
ground through connection to a
properly grounded fluid hose and pump.
Fluid supply container:
follow local code.
Solvent pails used when flushing:
follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure:
hold metal part of the dispense
valve firmly to the side of a grounded metal pail, then
trigger the dispense valve.
Accessories
Install the following accessories in the order shown in
F
. 2, page 7, using adapters as necessary.
Air and Fluid Hoses
Be sure all air hoses (H) and fluid hoses (N) are properly
sized and pressure-rated for your system. Use only
electrically conductive hoses.
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.

A main air bleed valve (C), pump air bleed valve
(E), and fluid drain valve (M) are required. These
accessories help reduce the risk of serious injury,
including fluid injection and splashing of fluid in the
eyes or on the skin, and injury from moving parts if
you are adjusting or repairing the pump.
The main air bleed valve (C) shuts off the air to the
pump and ram. The pump air bleed valve (E)
relieves air trapped between this valve and the
pump after the air is shut off. Trapped air can
cause the pump to cycle unexpectedly. Locate the
valve close to the pump. Order Part 107141.
The fluid drain valve assists in relieving fluid pressure
in the displacement pump, hose, and dispense valve.
Triggering the dispense valve to relieve pressure may
not be sufficient. Order Part 235992.
