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 Acces-

sories, available from your Graco distributor. If you
supply your own accessories, be sure they are ade-
quately sized and pressure rated for your system.

Figure 2 is only an example 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 equip-
ment.

Prepare the Site

The pump requires 12 scfm (0.34 m

/min) of com-

pressed air while operating at 400 kPa (4 bar, 60 psi)
air pressure and a flow rate of 3.8 liters/min (1.0 gpm).
Ensure that you have an adequate compressed air
supply.

Refer to Figure 2. Bring a compressed air supply line
(B) from the air compressor to the pump location. Be
sure all air hoses are properly sized and pressure-
rated for your system. Use only electrically conductive
hoses.

Install a bleed-type shutoff valve (G) in the air line to
isolate the air line components for servicing. Install an
air line moisture trap and drain valve (A) to help re-
move moisture from the compressed 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 or draining the fluid filter.

Grounding

WARNING

FIRE AND EXPLOSION HAZARD

Before operating the pump, ground the
system as explained below. Also read
the section

 FIRE OR EXPLOSION

HAZARD

 on page 4.

1.

Pump (for pumps without pre–installed ground
wire): use the ground wire and clamp (supplied).
See Fig. 1. Loosen the grounding lug locknut (W)
and washer (X). Insert one end of the ground wire
(Y) into the slot in lug (Z) and tighten the locknut
securely. Connect the other end of the wire to a 
true earth ground.

2.

Air and fluid hoses: use only electrically conductive
hoses.

3.

Heater, if used: refer to heater manual 307–805.

4.

Air compressor: follow manufacturer’s recommen-
dations.

5.

Spray gun: ground through connection to a prop-
erly grounded fluid hose and pump.

6.

Fluid supply container: follow your local code.

7.

Object being sprayed: follow your local code.

8.

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 continu-
ity.

9.

To maintain grounding continuity when flushing or
relieving pressure, hold a metal part of the spray
gun firmly to the side of a grounded 

metal pail,

then trigger the gun.
