NOTE: The reference numbers and letters in parenthe-
ses in the text refer to the callouts in Figures 1–6
and the Parts Drawing.
The Typical Installation shown above is only a
guide to selecting and installing required and op-
tional accessories. For assistance in designing a
system to suit your particular needs, contact
your Graco representative.
The dimensional drawing on page 26 gives measure-
ments needed for installing the pump on a custom de-
signed mounting.
Accessories
Refer to the TYPICAL INSTALLATION drawing, above,
and ACCESSORIES on page 18–20 for assistance in
setting up your system. If you supply your own accesso-
ries, be sure they are adequately sized to meet the sys-
tem's requirements. If your pump is mounted in a ram or
an elevator, refer to the manual supplied with it for instal-
lation and operation instructions.
Install the accessories in the order shown in the Typical
Installation drawing. The pump runaway valve (R)
senses when the pump is running too fast and shuts off
the air supply to the motor. The air line lubricator (F) pro-
vides automatic air motor lubrication. The bleed–type
master air valve (G) relieves air trapped between it and
the pump when it is closed. Be sure the valve is easily ac-
cessible from the pump. The air regulator (H) controls
pump speed and outlet pressure. The air line filter (E) re-
moves harmful dirt and moisture from the compressed air
supply.

WARNING
Two accessories are required in your system: a
bleed–type master air valve (G) and a fluid drain
valve (J). These accessories help reduce the risk of
serious bodily injury including fluid injection, splash-
ing in the eyes or on the skin, and injury from moving
parts if you are adjusting or repairing the pump.
The bleed–type master air valve relieves air trapped
between this valve and the pump after the air is shut
off. Trapped air can cause the pump to cycle unex-
pectedly. Locate the valve close to the pump.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose and spray gun;
triggering the spray gun to relieve pressure may not
be sufficient.
Using a suitable adapter, connect a fluid drain valve (J)
near the 1 in. npt(f) fluid outlet of the pump. Then connect
a grounded fluid supply hose (K). For more flexible spray
gun movement, use a shorter 13 mm (1/2 in.) ID hose (L)
between the spray gun and the main hose.
GROUNDING
WARNING
Before operating the pump, ground the system as
explained under FIRE OR EXPLOSION HAZARD
and Grounding on page 5.
