NOTE: Reference numbers and letters in parentheses

parts drawings.
1. Mount the pump to suit the type of installation
planned. The pump dimensions and mounting hole
layout are shown on page 11.
2. The Typical Installation shown above is only a
guide. Contact your Graco distributor for assis-
tance in designing a system to suit your needs.
3. Install the accessories as explained in the following
steps. If you supply your own accessories, be sure
they are adequately sized for you system.
WARNING
Two accessories, the bleed-type master air
valve (D), and the fluid drain valve (K) are required
in your system to reduce the risk of serious injury
from moving parts or splashing fluid in the eyes or
on the skin when shutting off the pump.
The Bleed-T ype Master Air V alve relieves air
trapped between the valve and the pump, after the
pump is shut off. Trapped air can cause the pump
to cycle unexpectedly and result in serious bodily
injury if you are adjusting or repairing the pump.
The Fluid Drain V alve helps relieve fluid pressure in
the displacement pump, hose, and gun/dispensing
valve when shutting off the pump. Triggering the
gun/dispensing valve may not be sufficient, espe-
cially if there is a clog in the hose, gun/dispensing
valve, or tip/nozzle.

4. Install the air line accessories in the approximate
order shown. To reduce stress on the air inlet
fitting, do not mount any accessories directly at the
air inlet fitting. Mount accessories on a bracket or
other fixture and use a hose between the accesso-
ries and air inlet. Use the shortest practical length
of hose.
The pump runaway valve (B) stops the supply of
air to the pump if the pump begins to run too fast,
which usually indicates a depleted fluid supply.
The air motor lubricator (C) automatically lubri-
cates the motor. Adjust the lubricator to dispense
about one drop of lubricant per minute.
The air regulator and gauge (E) controls pump
speed and fluid pressure.
The air filter (F) removes dirt and moisture from
the compressed air supply. Damp or dirty air can
damage the air motor.
Use electrically conductive air hoses. Connect an
electrically conductive air supply hose (G) to the
main air supply line. Read the Fire and Explosion
Hazard on page 3.
5. Install a fluid drain valve (K) close to the pump fluid
outlet. Read the Warning to the left. Use a fluid
filter (not shown), if needed.
6. Connect an electrically conductive fluid outlet hose
(J) to the pump. Read the warning section Fire
and Explosion Hazard on page 3.
