Installation
NOTES:
D Reference numbers and letters in parentheses in
the text refer to the callouts in the figures and
drawings.
D Always use Genuine Graco Parts and Accessories,
available from your Graco distributor. If you supply
your own accessories, be sure they are adequately
sized and pressure-rated to meet the system’s
requirements.
D Fig. 2 is only a guide for selecting and installing
system components and accessories. Contact your
Graco distributor for assistance in designing a
system to suit your particular needs.
Prepare the Operator
All persons who operate the equipment must be
trained in the safe, efficient operation of all system
components as well as the proper handling of all fluids.
All operators must thoroughly read all instruction
manuals, tags, and labels before operating the
equipment.
Prepare the Site
Ensure that you have an adequate compressed air
supply. Refer to the performance chart on page 15 to
find the air consumption of your pump.
Keep the site clear of any obstacles or debris that
could interfere with the operator’s movement.
Have a grounded, metal pail available for use when
flushing the system.
Mounting the Pump
Screw the bung adapter (B) tightly into the drum bung
hole and tighten the thumbscrew to hold the pump
about 13 mm (0.5 in.) off the bottom of the drum.
Loosen the drum vent plug to prevent forming a
vacuum. The pump dimensions are shown on page 13.
Grounding
WARNING
FIRE AND EXPLOSION HAZARD

system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 4.
D Pump: Use a ground wire and clamp. See Fig.1.
Loosen the grounding lug locknut (W) and washer
(X). Insert one end of a 12 ga (1.5 mm
@) minimum
ground wire (Y) into the slot in lug (Z) and tighten

D Air and fluid hoses: Use only electrically conductive
hoses with 150 m (500 ft) maximum combined hose
length to ensure grounding continuity.
D Air compressor: Follow manufacturer’s
recommendations.
D Spray gun or dispensing valve: Connect to a
properly grounded fluid hose and pump.
D Object being sprayed: Follow your local code.
D Fluid supply container: Follow your local code.
D Solvent pails used when flushing: Follow your local
code. Use only metal pails, which are conductive,
placed on a grounded surface. Do not place the
pail on a nonconductive surface, such as paper or
cardboard, which interrupts the grounding
continuity.
D To maintain proper grounding continuity when
flushing or relieving pressure, always hold the metal
part of the spray gun/dispense valve firmly to the
side of a grounded metal pail, then trigger the
gun/valve.
