Grounding
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
Pump: use the ground wire and clamp (supplied). See
F
IG. 1. Use the ground screw (GS) and lock washer
(LW) to attach the ground wire (N) at the rear of the air
motor. Tighten the screw securely. Connect the other
end of the ground wire to a true earth ground (P).
Air and fluid hoses: use only electrically conductive
hoses.
Air compressor: follow manufacturer’s recommenda-
tions.
Spray gun / Dispense valve: ground through connec-
tion to a properly grounded air or fluid hose and pump.
Air hose is conductive and used to ground gun. If adding
lengths to hose be sure to use conductive hoses.
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 sur-
face, 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/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
Flush Before Using Equipment
The equipment was tested with water. To avoid contami-
nating your fluid with water, flush the equipment with a
compatible solvent before using the equipment. See
your pump manual. See Related Manuals, page 2.
