NOTES:
Be sure that all operators read and understand this
entire manual and the separate manuals supplied
with components and accessories before using this
equipment.
Reference numbers and letters in parentheses refer
to the figures and parts lists.
Accessories are available from your Graco distribu-
tor. If you supply your own accessories, be sure the
are adequately sized to meet your system's require-
ments.
The Typical Installation on page 6 is only an
example. For assistance in designing a system to
meet your particular needs, contact your Graco
distributor.
System Accessories
WARNING
Two required components are supplied with your
pump, to help reduce the risk of serious injury
including fluid injection, splashing in the eyes or on
the skin, or injury from moving parts if you are
adjusting or repairing the pump.
The bleed-type master air valve (B) relieves air
trapped between this valve and the pump. Trapped
air can cause the pump to cycle unexpectedly. To
bleed air from the pump, the pump air regulator
(F) must be open when you close this valve.
The fluid drain valve (H) assists in relieving fluid
pressure in the displacement pump, hose, and gun;
triggering the gun to relieve pressure may not be
sufficient.
Install an air line filter (E) in the main air line, to re-
move harmful dirt and moisture from the compressed
air supply. To provide automatic lubrication of the air
motor, install an air line lubricator (P) downstream from
the pump air regulator (F). Install a second master air
valve (D) in the main air line, to isolate the accessories
for servicing.
Installation
Mounting the Pump
Mount the wall bracket 5 ft (1.5 m) above the floor. Be
sure the wall is strong enough to support the weight of
the pump and accessories, fluid, hoses, and stress
caused during pump operation. See Fig. 2 for a brack-
et mounting hole pattern.
Fig. 2
A pump runaway valve is available. The runaway valve
senses when the pump is running too fast and auto-
matically shuts off the air to the motor. A pump which
runs too fast can be seriously damaged. Install the
runaway valve (R) at the location shown in the Typical
Installation.
Hose and Gun Connections
Refer to the Typical Installation. Apply thread sealant
and screw the suction hose (J) into the fluid intake
elbow (S).
Connect one end of the fluid hose (L) to the filter (K)
outlet and the other to the fluid inlet of the spray gun
(N). Do not install the spray tip in the gun yet.
Close the bleed-type master air valve (B) and the air
regulators (F and G). Connect a grounded air hose (M)
between the outlet of the gun air regulator (G) and the
air inlet of the spray gun (N). The pump ar regulator
(F) is connected to the pump (A) with a hose (C).
