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 Accesso-
ries, available from your Graco distributor. If you supply
your own accessories, be sure they are adequately
sized and pressure-rated for your system.
F . 1 is only a guide for selecting and installing system
IG
components and accessories. Contact your Graco dis-
tributor 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 operation of all system components as well as the
proper handling of all fluids. All operators must thor-
oughly read all instruction manuals, tags, and labels
before operating the equipment.

Prepare the Site

Ensure that you have an adequate compressed air
supply.
Bring a compressed air supply line from the air com-
pressor to the pump location. Be sure all air hoses are
properly sized and pressure-rated for your system. Use
only electrically conductive hoses. The air hose should
have a 3/8 npt(m) thread. A quick disconnect coupling is
recommended.
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.

Wall Mount Packages

1. Be sure the wall can support the weight of the
pump, bracket, hoses and accessories, as well as
the stress caused during operation.
2. Position the wall bracket about 1.2-1.5 m (4-5 ft)
above the floor. For ease of operation and service,
make sure the pump air inlet, fluid inlet, and fluid
outlet ports are easily accessible.
3. Using the wall bracket as a template, drill 10 mm
(0.4 in.) mounting holes in the wall. Wall mounting
dimensions are shown on page 48.
4. Attach the bracket to the wall. Use 3/8 in. (9 mm)
screws that are long enough to keep the pump from
vibrating during operation.
NOTE: Be sure the bracket is level.

Components

See F . 1. Components vary by package ordered, but
IG
may include:
• The red-handled bleed-type master air valve (E) is
required in your system to relieve air trapped
between it and the air motor and gun when the valve
is closed. Do not block access to the valve.
• The pump air regulator (H) controls pump speed
and outlet pressure by adjusting the air pressure to
the pump.
• The air relief valve (not shown) opens automatically
to prevent overpressurization of the pump.
• The gun air regulator (D) adjusts the air pressure to
the air-assisted spray gun (L).
• The air-assisted or airless spray gun (L) dispenses
the fluid. The gun houses the spray tip (not shown),
which is available in a wide range of sizes for differ-
ent spray patterns and rates of flow. Refer to gun
manual for tip installation.
