Installation - Graco A Series Instructions-Parts List Manual

NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawings.
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 to meet the system's
requirements.
Fig. 2 is only a guide for selecting and installing sys-
tem 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
Ensure that you have an adequate compressed air
supply. Refer to the performance chart on page 22 to
find the air consumption of your pump.
Mount the pump (V) to suit the type of installation
planned. Fig. 2 shows the pump mounted on a wall
bracket (U). The pump dimensions and mounting hole
layout are shown on page 23.
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.

Installation

Grounding
1. 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
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. For a ground wire and
clamp, order Part No. 237569.

2. Air and fluid hoses: use only electrically conductive
hoses.
3. Air compressor: follow manufacturer's recommen-
dations.
4. Spray gun: ground through connection to a prop-
erly grounded fluid hose and pump.
5. Fluid supply container: follow your local code.
6. Object being sprayed: follow your local code.
7. 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.
8. 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.
