Installation
General Information
•
A typical installation is shown in
. It is only a
guide for selecting and installing system
components. Contact your Graco distributor for
assistance in planning a system to suit your needs.
•
Always use genuine Graco parts and accessories.
•
Reference numbers and letters in parentheses refer
to the callouts in the figures.
Before First Use
After you unpack the equipment, and before you use it
for the first time, check and torque all external fasteners.
, page 29. After the first day of
operation, retorque the fasteners.
Check and tighten all air and fluid connections before
operating the equipment. Replace worn or damaged
parts as needed.
Grounding
Pump:
Connect a ground wire and clamp (Y) as shown
in F
IG
. 2. To order a ground wire and clamp, order part
number 238909. Loosen the grounding screw (W). Insert
one end of a 12-gauge (1.5 mm
2
) or thicker ground wire
behind the grounding screw and tighten the screw
securely. Connect the clamp end of the ground wire to a
true earth ground.
•
Air and fluid lines:
Use only conductive lines with a
maximum of 500 ft (150 m) combined line length to
ensure grounding continuity. Check electrical
resistance of lines. If total resistance to ground
exceeds 29 megohms, replace line immediately.
•
Air compressor:
Follow manufacturer’s
recommendations.
•
Fluid supply container:
Follow local codes and
regulations.
•
Solvent pails used when flushing:
Follow local
codes and regulations. Use only conductive metal
pails, placed on a grounded surface. Do not place
the pail on a nonconductive surface, such as paper
or cardboard, which interrupts grounding continuity.
NOTICE
Firmly tighten all connections to avoid air or fluid
leaks. To avoid equipment damage, do not
over-torque the fasteners on the equipment.
See
, page 29.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current. Follow local codes and
regulations.
