10 312376L
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 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.
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
for system accessory installation instructions.
