Supplied Components
Refer to Fig. 1 on page 9.
WARNING
A red-handled bleed-type master air valve (11h)
and a fluid drain valve (D) are supplied. These
components help reduce the risk of serious injury,
including splashing of fluid in the eyes or on the
skin, and injury from moving parts if you are adjusting or repairing the pump.
The bleed-type master air valve relieves air trapped
between this valve and the pump after the air is
shut off. Trapped air can cause the pump to cycle
unexpectedly. Locate the valve close to the pump.
The fluid drain valve assists in relieving fluid pressure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient.
The red-handled bleed-type master air valve
(11h) is required in your system to relieve air
trapped between it and the air motor when the
valve is closed (see the WARNING above). Be sure
the bleed valve is easily accessible from the pump,
and is located downstream from the pump air
filter/regulator (11a).
The pump air filter/regulator (11a) controls pump
speed and outlet pressure by adjusting the air
pressure to the pump. It includes an air filter with a
40 micron polypropylene element, to remove harmful dirt and moisture from the compressed air
supply. Locate close to the pump, but upstream
from the bleed-type master air valve (11h).
The air line lubricator (11b) provides automatic
lubrication of the air motor.
The air relief valve (11j) opens automatically to
prevent overpressurization of the pump.
Fluid is supplied to the pump through the suction
hose (16) and tube (50 or 109). On Circulation
Packages 232–089 and 232–091, the suction tube
(109) is installed in the shaft of the agitator (102).
See Fig. 1.
The fluid filter (5) includes a 60 mesh (250 micron) stainless steel element to filter particles from
the fluid as it leaves the pump.
The fluid drain valve (D), is mounted in the bottom of the fluid filter bowl, and is required in your
system to relieve fluid pressure in the hose and gun
(see the WARNING at left).
The back pressure regulator (12) controls back
pressure to the gun and maintains proper circulation pressure.
The back-geared agitator (102) keeps the fluid in
suspension and also includes a suction tube (109)
to draw fluid from a 55 gallon drum. Included with
Circulation Packages 232–089 and 232–091 only.
The air-operated elevator (150) allows you to
raise the drum cover and agitator from an empty
drum, replace the drum, and lower the agitator into
the new drum. Included with Circulation Packages
232–089 and 232–091 only.

Operation
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or
moving parts, follow the Pressure Relief Procedure whenever you:
D
D
D
D
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray nozzle.
1. Close the red-handled bleed-type master air valve
(11h, required in your system). See Fig. 5 on page
15.
2. Place the drain hose (42) into a waste container.
Turn the 3-way recirculation valve (19) to the drain
position.
3. Trigger the gun at the last gun station to relieve
fluid pressure. Maintain firm metal-to-metal contact
between the gun and a grounded waste pail.
Repeat for all gun stations.
4. Open the drain valve (D) to relieve fluid pressure
which may be trapped in the pump or hose.
12
308-768
If you suspect that pressure is not fully relieved after
following the steps above, wrap a fitting near the pump
outlet with a rag, and slowly and carefully loosen the
fitting to relieve pressure. Be careful to protect your
eyes from splashing.
Packing Nut
Before starting, fill the packing nut (H) 1/3 full with
Graco Throat Seal Liquid (TSL) or compatible solvent.
See Fig. 5 on page 15.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
The packing nut is torqued at the factory and is ready
for operation. If it becomes loose and there is leaking
from the throat packings, relieve pressure, then torque
the nut to 34–40 NSm (25–30 ft-lb). Do this whenever
necessary. Do not overtighten the packing nut.
Flush the Pump Before First Use
The pump is tested with lightweight oil, which is left in
to protect the pump parts. If the fluid you are using
may be contaminated by the oil, flush it out with a
compatible solvent. See Flushing on page 16.
Operation
Starting and Adjusting the Pump
9. One at a time, open any other guns in the system
to purge air from the lines.
1. Open all fluid shutoff valves (14, 15). Refer to Fig.
1 on page 9, and to Fig. 5.
2. Open the back pressure regulator (12). Turn the
3-way recirculation valve (19) to the circulation
position.
3. Open the spray gun at the last gun station and
keep it open while starting the pump.
4. Open the bleed-type master air valves (11h, B).
5. Slowly open the air filter/regulator (11a) until the
pump starts. The air filter/regulator controls the
pump speed and fluid outlet pressure.
6. Adjust the fluid pressure to the lowest setting
necessary to get the desired results. Higher pressures may not improve the spray pattern and will
cause premature component wear. Use the air
filter/regulator (11a) and the back pressure regulator (12) to adjust the pump speed and fluid pressure until the spray is completely atomized. Refer
to the back pressure valve manual (supplied) for
adjustment procedures.
7. To adjust the spray pattern, follow the complete
instructions in your gun manual.
8. When you have achieved the desired spray pattern, release the gun trigger. The pump will continue to cycle as long as air is supplied and the back
pressure regulator (12) is open.
NOTE: In a circulating system, the pump will continue
to cycle as long as air is supplied and the back pressure regulator is open. In a direct supply system, the
pump starts when the gun is opened, and stops when
the gun is closed.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause
component rupture and serious injury,
never exceed the specified maximum air input
pressure to the pump (see Technical Data on
page 24).
CAUTION
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If your
pump is running too fast, stop it immediately and
check the fluid supply. If the container is empty and
air has been pumped into the lines, refill the container and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.

Maintenance
Preventive Maintenance Schedule
The operating conditions of your particular system
determine how often maintenance is required. Establish a preventive maintenance schedule by recording
when and what kind of maintenance is needed, and
then determine a regular schedule for checking your
system.
Flushing
WARNING
FIRE AND EXPLOSION HAZARD
Before flushing, read the section FIRE
AND EXPLOSION HAZARD on page
5. Be sure the entire system and flushing pails are properly grounded. Refer to
Grounding on page 11.
Flush the pump:
Before the first use
When changing colors or fluids
3. Remove the filter element from the fluid filter (5).
Reinstall the filter bowl.
4. Open the back pressure regulator (12). Set the
3-way recirculation valve (19) to the circulation
position.
5. Place the suction tube (50) in a container of solvent, or lower the agitator (102) into a container of
solvent. Start the agitator and run it slowly.
6. Hold a metal part of the gun firmly to the side of a
grounded metal pail.
7. Start the pump. Always use the lowest possible
fluid pressure when flushing.
8. Trigger the gun. Flush the system until clear
solvent flows from the gun.
9. Release the gun trigger and lock the trigger safety.
The pump will continue to cycle as long as air is
supplied and the back pressure regulator (12) is
open.
10. Direct the drain hose (42) into a waste container.
Set the 3-way recirculation valve (19) to the drain
position. Continue flushing until clear fluid comes
from the hose.
Before fluid can dry or settle out in a dormant pump
(check the pot life of catalyzed fluids)
11. Relieve the pressure.
Before storing the pump.
12. Clean the air cap, spray tip, and fluid filter element
separately, then reinstall them.
Flush with a fluid that is compatible with the fluid you
are pumping and with the wetted parts in your system.
Check with your fluid manufacturer or supplier for
recommended flushing fluids and flushing frequency.
CAUTION
If you have a carbon steel pump, never leave water
or water-base fluid in the pump overnight. If you are
pumping water-base fluid, flush with water first, then
with a rust inhibitor such as mineral spirits. Relieve
the pressure, but leave the rust inhibitor in the pump
to protect the parts from corrosion.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 12.
1. Relieve the pressure.
2. Remove the air cap and spray tip from the gun.
See the gun manual.

Air Filter Service
Repair Kits are available. Refer to page 17.
Every day, drain contaminants from the bowl before
reaching the baffle level by opening the drain (P) at the
bottom of the bowl (N).
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 12.
Clean the air filter regularly to maximize filtering efficiency and to avoid excessive pressure drop. Fully
relieve pressure to remove the bowl (N).
Clean the filter element (211) and bowl using household soap and water or denatured alcohol. Use compressed air to blow out the filter body. Blow the filter
element out from the inside.
Clean the sight glass (209) thoroughly. Do not leave
solvent residue in the sight glass as it may attack or
weaken the glass. If the sight glass appears damaged,
replace it immediately.
