Installation
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 displacement pump manuals 311825, 311827, and 312745.
See F
IG. 1. Connect the suction hose (P) between the
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.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid contaminating 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 FIG. 1. Air Controls are included with all packages.
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 unexpectedly,
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.
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 Wall Mounting
Bracket Diagram, 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.

Grounding
Although water generally provides a natural electrical
ground, the following equipment must be grounded if the
cleaning chemicals are volatile.
The equipment must be grounded. Grounding reduces
the risk of static and electric shock by providing an
escape wire for the electrical current due to static build
up or in the event of a short circuit.
When cleaning in enclosed areas, such as storage
tanks, locate the pump and air compressor outside the
area and well away from it. Provide adequate ventilation.
If the area you are cleaning has stored flammable materials. take appropriate precautions to avoid static sparking. Consult your local codes.
Pump: use supplied ground wire and clamp. See F
Use the ground screw (GS) and lockwasher (LW) to
attach the ground wire (U) at the rear of the air motor.
Tighten the screw securely. Connect the other end of the
ground wire to a true earth ground.
IG. 2.
Air and fluid hoses: use only electrically conductive
hoses.
Air compressor: follow manufacturer’s recommendations.
Spray gun / Dispense valve: ground through connec-
tion to a properly grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray
gun/dispense valve firmly to the side of a grounded
metal pail, then trigger the gun/valve.

Operation
Operation
Pressure Relief Procedure
Trapped air can cause the pump to cycle unexpectedly,
which could result in serious injury from splashing or
moving parts.
1. Engage the trigger lock.
2. Close the bleed-type master air valve to shutoff the
pump.
3. Disengage the trigger lock.
4. Hold a metal part of the gun firmly to a grounded
metal pail. Trigger the gun to relieve pressure.
5. Engage the trigger lock.
6. Open all fluid drain valves in the system, having a
waste container ready to catch drainage. Leave the
drain valve(s) open until you are ready to spray
again.
7. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after following the steps above, VERY SLOWLY loosen the tip
guard retaining nut or hose end coupling to relieve
pressure gradually, then loosen completely. Clear
the hose or tip obstruction.
Cleaning Solutions
Prepare the cleaning solution according to the manufacturer’s instructions. Be sure to observe all warnings. If
you are using powdered cleaners, mix them thoroughly
in a separate pail before adding them to a supply drum.
Undissolved powders are extremely abrasive and may
damage pump parts.
Wear appropriate protective clothing, such as waterproof outerwear and eye goggles, according to the
cleaner manufacturer’s recommendations. Cleaning
chemicals may be toxic, and cause serious irritation to
your eyes or skin.
Flushing
To reduce the risk of fluid injection injury, static sparking, or splashing, relieve the pressure, and remove the
spray tip (spray guns only) before flushing.
Hold a metal part of the gun/valve firmly to the side of a
grounded metal pail and use the lowest possible fluid
pressure during flushing.
