The
Typical Installation
above is only a guide to
selecting and installing accessories. For assistance in
designing a system to meet your needs, contact your
Graco distributor.
The
Dimensional Drawings
on page 25 provide
necessary measurements for installing the pump on a
custom designed mounting.
System Accessories
Refer to the
Typical Installation
drawing, above for
assistance in setting up your system. If you supply
your own accessories, be sure they are adequately
sized to meet the system’s requirements. If your pump
is mounted in a ram or elevator, refer to the manual
supplied with it for installation and operation instruc-
tions.
Install the accessories in the order shown in the Typi-
cal 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) provides 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 accessible from the pump. The air
regulator (H) controls pump speed and outlet pressure.
The air line filter (E) removes harmful dirt and moisture
from the compressed air supply.
WARNING
A bleed-type master air valve (G) and a fluid drain
valve (J) are required in your system. These acces-
sories help reduce the risk of serious injury includ-
ing fluid injection, splashing in the eyes or on the
skin, and injury from moving parts if you are adjust-
ing 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
unexpectedly . Position 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.
