installing system components and accessories. Contact
your Graco distributor for assistance in designing a sys-
tem 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.
NOTICE
The compressed air supply to the gun must be
clean and dry, to prevent damage to the finish. Use
a coalescing air filter in the main air supply line.
Bring a compressed air supply line from the air com-
pressor to the pump location. Refer to the performance
charts in your pump assembly manual to find the air
consumption of your pump. 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.
Install a bleed-type shutoff valve (A) in the air line to iso-
late the air line components for servicing. Install an air
line filter (B) and a moisture trap and drain valve (C) to
help remove moisture and contaminants from the com-
pressed air supply.

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.

Mount the Pump

Mount the pump directly to the wall or to a Graco cart.
See page 37 for mounting kits.
Wall-Mounted Pumps
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 4-5 ft (1.2-1.5 m)
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 0.4 in. (10
mm) mounting holes in the wall. Wall mounting
dimensions are shown on page 41.
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.
Cart-Mounted Pumps
Kit 24E885 is available if you plan to bolt your cart to the
floor. It includes two spacers that keep the legs stable.
Bolts not included.
