Grounding
Pump:
use ground wire and clamp (Graco P/N 222011,
not supplied), as shown in F
1.
Connect the ground wire (Y) to the ground screw (Z)
located on the bottom of the air motor.
2.
Connect the other end of the ground wire (Y) to a
true earth ground.
Air and fluid hoses:
use only electrically conductive
hoses.
Air compressor:
follow manufacturer’s
recommendations.
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/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.
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.
