Installation
The Graco warranty will not apply if cleaning solutions
other than those recommended by Graco are used in
these units. Only use solutions that are not harmful to
the wetted parts. See the Technical Data in the dis-
placement pump manuals 311825, 311827, and
312745.

. 1. Connect the suction hose (P) between the
IG
pump fluid inlet and the suction tube (R), using thread
sealant on the male threads. Screw on the suction tube
strainer. Place the suction tube in the supply drum, and
adjust it so it is 1 in. (25 mm) off the bottom of the drum.
Tighten the thumbscrew of the pipe hanger onto the
drum.
Connect the spray hose (S) to the pump outlet manifold.
For two gun spraying, remove the plug in the manifold
and connect another spray hose. Connect the spray gun
(T) to the hose (S). Use thread sealant on the male
threads.
Wall Mount Packages
1. Ensure the wall is strong enough to support the
weight of the pump assembly and accessories, fluid,
hoses, and stress caused during pump operation.
2. Ensure that the mounting location has sufficient
clearance for easy operator access.
3. Position the wall bracket at a convenient height,
ensuring that there is sufficient clearance for the
fluid suction line and for servicing the displacement
pump.
4. Drill four 7/16 in. (11 mm) holes using the bracket as
a template. Use any of the three mounting hole
groupings in the bracket. See Dimensions, page
22.
5. Bolt the bracket securely to the wall using bolts and
washers designed to hold in the wall's construction.
6. Attach the pump assembly to the mounting bracket.
7. Connect air and fluid hoses.

Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
your respective pump manual. See Related Manuals
on page 3.
Air Controls
See F
. 1. Air Controls are included with all packages.
IG
The following parts are included (see 3A0293 for
detailed information):
•
Bleed-type master air valve (D): required in your
system to relieve air trapped between it and the air
motor when the valve is closed.
Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from splashing
or moving parts.
•
Pump regulator assembly (E): The regulator
adjusts air pressure to the motor and fluid outlet
pressure of pump. View the gauge (F) to read air
pressure. The filter removes harmful contaminants
from entering the air control module and air motor.
•
Safety relief valve (G): automatically opens to
relieve air pressure, to prevent pump overpressur-
ization.
