Grounding the System
Junction Box Panel (H): connect the electrical supply
ground wire to the ground lug. See Connecting Power
to the Junction Box on page 22.
Pump: use a ground wire and clamp. Verify that the
ground screw (GS) is attached and tightened securely to
the air motor. Connect the clamp (U) of the static ground
cable assembly to a true earth ground. For a ground
wire and clamp, order Part No. 244524.
Air and fluid hoses: use only electrically conductive
hoses.
Air compressor: follow manufacturer’s
recommendations.
Spray gun / Dispense valve: ground through
connection to a properly grounded fluid hose and Pump.
Fluid supply container: follow local code.
Object being sprayed: 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 spray gun
firmly to the side of a grounded metal pail, then trigger
the gun.
Checking the Resistance
Between the Pumps and the
True Earth Ground
Check the resistance between each Pump and the true
earth ground. If the resistance is greater than 1.0 ohms,
a different ground site may be required. Do not operate
the system until the problem is corrected.
NOTE: Use a meter that is capable of measuring
resistance at this level.
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.

To reduce the risk of fire, explosion, or electric shock,
the resistance between the Supply Unit components
and true earth ground must be less than 1.0 ohms.
