Grounding
Proper grounding is an essential part of maintaining a
safe system.
Pump:
use ground wire and clamp (supplied) as shown
in F
IG
. 2.
Air compressor:
follow manufacturer’s
recommendations.
Object being dispensed to:
follow local code.
Fluid supply container:
follow local code.
To maintain grounding continuity when flushing or
relieving pressure:
hold metal part of thedispense
valve firmly to the side of a grounded metal container,
then trigger the valve.
To ground the pump,
remove the ground screw (Z) and
insert through eye of the ring terminal at the end of the
ground wire (Y). Fasten the ground screw back onto the
pump and tighten securely. Connect the other end of the
wire to a true earth ground. To order a ground wire and
clamp, order Part No. 222011.

Required Accessories
•
Bleed-type master air valve (E):
required in your
system to relieve air trapped between it and the air
motor after the air supply is shut off. Trapped air can
cause the air motor to cycle unexpectedly, causing
serious injury if you are adjusting or repairing the
pump. As an alternative, use a quick-disconnect
couple fitting. Install them near the pump air inlet
within easy reach from the pump.
•
Fluid drain valve (N):
assists in relieving fluid
pressure in the displacement pump, hoses and
dispensing valve. Triggering the valve to relieve
pressure may not be sufficient.
•
Grounding wire (G):
reduces the risk of static
sparking.
Additionally, for permanent installations, a thermal relief
kit is required.
•
Thermal Relief Kit (R):
assists in relieving pressure
in the pump, hose and dispensing valve due to heat
expansion.
Other Accessories
•
Extension Tubes:
Pump models 222103 and
222104 have extension tubes. An extension tube
may be added to the Universal pump for use in sub-
merged applications. To install, apply PTFE tape to
the female threads at the top of the tube. Thread the
tube tightly into the intake housing of the Universal
pump. Also install a bung adapter. To order a stan-
dard 2-inch bung adapter, order Part No. 222308.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.

Three accessories are required in your system to help
reduce the risk of serious bodily injury, including fluid
injection, splashing of fluid in eyes or on skin, injury
from moving parts when you are adjusting or repairing
the pump, and explosion from static sparking.
