Loosen the grounding lug locknut (W) and washer
(X). Insert one end of the ground wire (Y) into the

2.

Air and fluid hoses: use only electrically conductive
hoses.

3.

Air compressor: follow manufacturer’s recommen-
dations.

4.

Dispense valve: ground through connection to a
properly grounded fluid hose and pump.

5.

Fluid supply container: follow your local code.

6.

Container being dispensed into: 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 dis-
pense valve firmly to the side of a grounded 

metal

pail, then trigger the valve.

General Information

NOTE: Reference numbers and letters in parentheses
in the text refer to the callouts in the figures and the
parts drawing.

NOTE: Always use Genuine Graco Parts and Acces-
sories, available from your Graco distributor. Refer to
the Product Data Sheet for the pump, Form No.
304–410. If you supply your own accessories, be sure
they are adequately sized and pressure rated for your
system.

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.

Mounting the Pump

Mount the pump to suit the type of installation planned.
The pump dimensions are shown on page 14.

When mounting the pump in a 2 in. bung type drum,
use the accessory bung adapter 205–573. Remove the
intake valve as explained on page 10, slide the bung
adapter onto the cylinder, and replace the intake valve.
Screw the bung adapter tightly into the drum bung hole
and tighten the thumbscrew to hold the pump about
0.5” (13 mm) off the bottom of the drum. Loosen the
drum vent plug to prevent a vacuum from forming.

When mounting the pump in an open container, use
the accessory pump clamp 204–858 and bung adapter
205–573.

Screw the air exhaust muffler (A) into the 3/4 npt(f)
outlet (B) in the motor base.

WARNING

To avoid contaminating the fluid with lubricants, air
line scale, rust, etc., pipe the exhaust air outside of
the fluid product area. Vent the exhaust to a safe
place, away from people, animals or food handling
areas.
