Check your pump package’s identification (ID) plate (located on side of air
motor) for the 6-digit part number of your pump package. Use the following
matrix to define the construction of your pump package, based on the six dig
its. For example, pump package P29RSM represents the pump package (P); a
pressure ratio of 29:1 with an NXT3400 motor and a 250cc displacement pump
(29); a low noise motor with remote DataTrak (R); and a displacement pump
constructed of stainless steel (S) with MaxLife®coatings, packings, and
enclosed wet cup (M).
To order replacement parts, see Parts section starting on page 22. The digits in the matrix do not correspond to the
Ref. Nos. in the Parts drawings and lists.
Some configurations in the following matrix cannot be built.

Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama
tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back
to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where
applicable.
WARNING
SKIN INJECTION HAZARD
High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just
a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
• Do not point gun at anyone or at any part of the body.
• Do not put your hand over the spray tip.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Do not spray without tip guard and trigger guard installed.
• Engage trigger lock when not spraying.
• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,
checking, or servicing equipment.
MOVING PARTS HAZARD
Moving parts can pinch or amputate fingers and other body parts.
• Keep clear of moving parts.
• Do not operate equipment with protective guards or covers removed.
• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,
follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent
fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop
cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Ground all equipment in the work area. See Grounding instructions.
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.

Installation
Grounding
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.
Pump: use a ground wire and clamp. Loosen the
grounding lug locknut and washer. Insert one end of a
1.5 mm2(12 ga) minimum ground wire into the slot in
lug and tighten the locknut securely. Connect the other
end of the wire to a true earth ground. Order Part
237569 Ground Wire and Clamp.
Air and fluid hoses: use only electrically conductive
hoses.
Air compressor: follow manufacturer's recommenda
tions.
Spray gun/dispense valve: ground through connection
to a properly grounded fluid hose and pump.
Fluid supply container: follow your local code.
Object being sprayed: follow your 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 sur
face, 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.

System Accessories
Be sure all air lines (T) and fluid lines (S) are properly
sized and pressure-rated for your system. Use only
electrically conductive hoses. Fluid hoses must have
spring guards on both ends.
Mounting Accessories
Mount the pump package to suit the type of installation
planned. Pump dimensions are shown on page 30.
Refer to Check-Mate Displacement Pump manual
312375 for mounting hole layout.
Air Line Accessories
Install the following accessories as listed. Refer to FIG. 1
to see air line accessories represented in a typical sup
ply unit installation.
•Main air shutoff valve (W) isolates the air line
accessories for servicing. Locate upstream from all
other air line accessories.
•Air line filter (V) removes harmful dirt and moisture
from the compressed air supply. Also, install a drain
valve at the bottom of each air line drop, to drain off
moisture.
•Air regulator (G and AH) controls pump speed and
outlet pressure by adjusting the air pressure to the
pump. Locate the regulator close to the pump, but
upstream from the bleed-type master air valve.
•Air motor valve (AJ) is required in your system to
shut off the air supply to the pump (see WARNING).
When closed, the valve will bleed off all air in the
pump. Be sure the valve is easily accessible from
the pump.
•Pump runaway valve (AK) senses when the pump
is running too fast and automatically shuts off the air
to the motor. A pump which runs too fast can be
seriously damaged. Locate in the position shown.
•Pump bleed valve (P) is required in your system to
relieve fluid pressure in hose and gun (see WARN
ING).
Fluid Line Accessories
Install the following accessories as listed. Refer to FIG. 2
to see fluid line accessories represented in a typical
supply unit installation.
• Install a fluid shutoff valve at each gun/valve drop,
to isolate the gun/valve and fluid accessories for
servicing.
• Install a fluid drain valve near the pump fluidoutlet,
and at each gun/valve station. The drain valves are
required in your system to relieve fluid pressure in
the displacement pump, hose and gun/valve (see
WARNING). Drain valves at the gun/valve stations
may be mounted in the base of a fluid regulator,
using an adapter.
•Fluid regulator controls fluid pressure to the
gun/valve, and dampens pressure surges.
•Gun or dispense valve dispenses the fluid.
•Gun/valve swivel allows freer gun/valve move
ment.
A main air bleed valve and pump bleed valve (P) are
required. These accessories help reduce the risk of
serious injury, including fluid injection and splashing of
fluid in the eyes or on the skin, and injury from moving
parts if you are adjusting or repairing the pump.
The main air shutoff valve shuts off the air to the pump
and ram. The air motor valve relieves air trapped
between this valve and the pump after the air is shut
off. Trapped air can cause the pump to cycle unexpect
edly. Locate the valve close to the pump.
The pump bleed valve assists in relieving fluid pres
sure in the displacement pump, hose, and gun/valve.
Triggering the gun/valve to relieve pressure may not be
sufficient.
If using Check-Mate pump with Graco Supply Sys
tems, refer to Supply Systems Operation manual
for system accessory installation instructions.
For use with all other systems, use this section for
accessory installation instructions.
