General Information
NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.
NOTE: Always use Genuine Graco Parts and
Accessories, available from your Graco distributor.
Grounding
Pump: use a ground wire and clamp as shown in FIG. 1.
Loosen the grounding lug locknut (A) and washer (B).
Insert one end of a 12 ga (1.5 mm
2
) minimum ground
wire (C) into the slot in lug (D) and tighten the locknut
securely. Connect the other end of the wire to a true
earth ground.
Model No. 206078: remove the ground screw (Z) and
insert through the eye of the ring terminal at end of
ground wire (Y). Fasten the ground screw back onto the
pump and tighten securely. Connect the other end of
the ground wire to a true earth ground. See F
IG. 2. To
order a ground wire and clamp, order Part No. 222011.
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.
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/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun.
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.
