General Information
Grounding
1. Pump: use Part No. 238909 Ground Wire and
Clamp (supplied). See F
IG . 1. Insert one end of the
ground wire (Y) into the pump’s grounding clamp (X)
and tighten the screw (W) securely. Connect the
other end of the wire to a true earth ground.
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 properly
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 card-
board, which interrupts the grounding continuity.
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.
Install the Muffler
The muffler (C, F IG . 2) is shipped loose. Screw the muf-
fler into the muffler port before installing the pump.
Air and Fluid Hoses
See F IG . 2. Be sure all air hoses (A, P) and fluid hoses
(R, U) are properly sized and pressure-rated for your
system. Use only electrically conductive hoses. Fluid
hoses must have spring guards on both ends. Use a
swivel (S) between the fluid hose (R) and the gun (T) to
allow easier gun movement.
• Reference numbers and letters in parentheses
in the text refer to the callouts in the figures
and the parts drawing.
• Always use G enuine Graco Parts and Acces-
sories, available from your Graco distributor. If
you supply your own accessories, be sure they
are adequately sized and pressure-rated for
your system.
• F IG . 2 is a guide for selecting and installing
system components and accessories. It is not
an actual system design. Contact your Graco
distributor for assistance in designing a system
to suit your particular needs.
