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, FIG. 2) is shipped loose. Screw the muf-
fler into the muffler port before installing the pump.
Air and Fluid Hoses
See FIG. 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.

you supply your own accessories, be sure they
are adequately sized and pressure-rated for
your system.
