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 25.
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.
FIG. 3
ti8250a
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 pressure
in the displacement pump, hose, and gun/valve. Trig-
gering 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
312371 for system accessory installation instruc-
tions.
For use with all other systems, use this section for
accessory installation instructions.

Installation
312376A 9
•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. 1
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 fluid outlet,
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 movement.

Setup

Setup
Wet Cup
Before starting, fill the wet cup (AD) 1/3 full with Graco
Throat Seal Liquid (TSL) or compatible solvent.
Torque Wet Cup
The wet cup is torqued at the factory; however, throat
packing seals on Severe Duty pumps may relax over
time. Check wet cup torque frequently after initial
start-up and periodically after the first week of produc-
tion. Maintaining proper wet cup torque is important to
extending seal life.
To torque the wet cup, use the following steps.
1. Follow Pressure Relief Procedure on page 11.
2. Use the packing nut wrench (supplied) to torque the
wet cup; see the following table for torque values.
Do this whenever necessary. Do not overtighten the
wet cup.
The enclosed wet cup has a fill port in the cover.
MaxLife pumps use a special u-cup throat seal that
is non-adjustable.
