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.

• Reference numbers and letters in parentheses

in the text refer to the callouts in the figures

and the parts drawing.

• Always use

Genuine 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.
