The typical installation shown above is only a guide to
selecting and installing required and optional accesso-
ries. For assistance in designing a system to suit your
needs, contact your Graco distributor.
Mount the pump to suit the type of installation planned.
The pump mounting hole layout and dimensions are
shown on pages 18 and 19.
WARNING
A bleed-type master air valve (C) and a fluid drain
valve (D) are required in your system. These
accessories help reduce the risk of serious injury,
including fluid injection and splashing of fluid 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
unexpectedly. Locate the valve close to the pump.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient.
Connect a fluid suction hose (G) to the 2 in. npt(f)
intake of the pump if it is not immersed.
Next, install a bleed-type master air valve (C) to relieve
air trapped between the valve and the pump, an air
regulator (K) to control pump speed, an air filter (B) to
remove harmful dirt and moisture from the compressed
air supply, and another bleed-type air valve to isolate
the accessories for servicing.
On the fluid supply line, install a fluid drain valve (D) to
assist in relieving pressure.
Be sure all air and fluid accessories are properly sized
for your system, and are compatible with the fluid you
are pumping.
