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 displace-  
ment pump manuals 311825, 311827, and 312745.  
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.  
See FIG. 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.  
Integrated Air Control Module  
See FIG. 1. The integrated air control module (C) is  
included with all packages. It includes the following (see  
311239 for detailed information):  
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.  
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.  
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.  
Trapped air can cause the pump to cycle unexpectedly,  
which could result in serious injury from splashing or  
moving parts.  
2. Ensure that the mounting location has sufficient  
clearance for easy operator access.  
Pump air regulator (E): adjusts air pressure to the  
motor and fluid outlet pressure of pump. View the  
gauge (F) to read air pressure.  
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.  
Safety relief valve (G): automatically opens to  
relieve air pressure, to prevent pump overpressur-  
ization.  
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  
Air filter (H): removes harmful contaminants from  
entering the air control module and air motor.  
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.

Installation  
Air and fluid hoses: use only electrically conductive  
hoses.  
Grounding  
Air compressor: follow manufacturer’s recommenda-  
tions.  
Spray gun / Dispense valve: ground through connec-  
tion to a properly grounded fluid hose and pump.  
Although water generally provides a natural electrical  
ground, the following equipment must be grounded if the  
cleaning chemicals are volatile.  
Fluid supply container: follow local code.  
Object being sprayed: follow local code.  
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.  
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 sur-  
face, such as paper or cardboard, which interrupts  
grounding continuity.  
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 mate-  
rials. take appropriate precautions to avoid static spark-  
ing. Consult your local codes.  
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.  
Pump: use supplied ground wire and clamp. See FIG. 2.  
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.

Pressure Relief Procedure  
Cleaning Solutions  
Prepare the cleaning solution according to the manufac-  
turer’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.  
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.  
Wear appropriate protective clothing, such as water-  
proof 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.  
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.  
Flushing  
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.  
To reduce the risk of fluid injection injury, static spark-  
ing, or splashing, relieve the pressure, and remove the  
spray tip (spray guns only) before flushing.  
7. If you suspect the spray tip or hose is clogged or  
that pressure has not been fully relieved after follow-  
ing 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.  
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.
