one of the packages listed in this manual, select a site
with at least 5 ft (1.5 m) overhead clearance for the
wall mounted systems and at least 7 ft (2.1 m) for the
floor mounted systems.
Ensure that the wall is strong enough to support the
weight of the circulation package and accessories,
fluid, hoses, and stress caused during pump operation.
Bring a hydraulic supply line from the facility hydraulic
supply (Z) to the circulation package location. Be sure
all lines are properly sized and pressure-rated for the
system. Use only electrically conductive hoses.
Install a hydraulic supply line shutoff valve (W) in the
hydraulic line to isolate the line components for servic-
ing.
Keep the site clear of any obstacles or debris that
could interfere with the operator’s movement.
Have a grounded, metal pail available for use when
flushing the system.
Supplied Components
Refer to Fig. 1.
WARNING
A master hydraulic valve (W) and a fluid drain valve
(F) 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 master hydraulic valve shuts off the hydraulic
supply from the facility.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, fluid filter, hose,
and gun. Triggering the gun to relieve pressure
may not be sufficient.
DThe hydraulic supply line shutoff valve (W) is
required in your system to isolate the line compo-
nents for servicing. (See the preceding WARNING.)
DThe fluid drain valve (F), is mounted on the
bottom of the fluid filter bowl. The fluid drain valve
is required in your system to relieve fluid pressure
in the displacement pump, fluid filter, and surge
tank. (See the preceding WARNING.)
DThe pump (N), run by a hydraulic motor, circulates
fluid throughout the system. See pump manual
309136 and hydraulic motor manual 308048 for
further details.
DThe fluid filter (D) includes a 60 mesh (250 mi-
cron) stainless steel element to filter particles from
the fluid as it leaves the pump.
DThe fluid surge tank (J) protects against surges in
the fluid lines during gun use and system operation.
DThe fluid regulator and gauge (V) controls fluid
back pressure. The gauge provides a readout of
the circulation system fluid pressure. See manual

Operation
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The system pressure must be manually relieved to
prevent the system from starting or spraying acci-
dentally. To reduce the risk of an injury from acci-
dental spray from the gun, splashing fluid, or
moving parts, follow the Pressure Relief Proce-
dure whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray nozzle.
1. Fig. 4. Relieve the pressure of the entire system
following applicable system pressure relief proce-
dures. Ensure that system pressure is relieved
before proceeding with step 2.
2. Close hydraulic supply line shutoff valve (W).
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 fluid drain valve (2) to relieve fluid pres-
sure which may be trapped in the pump, plumbing,
or hose.
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
Fig. 4. Before starting, fill the packing nut (AA) 1/3 full
with Graco Throat Seal Liquid (TSL) or compatible
solvent.
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 Circulation Package Before First
Use
The circulation package is tested with lightweight oil,
which is left in to protect the circulation package parts.
If the fluid you are using may be contaminated by the
oil, flush it out with a compatible solvent. See Flush-
ing on page 13.

Operation
Starting and Adjusting the Pump
1. Fig. 4. Open all fluid shutoff valves (4–two) (36).
2. Open the spray gun at the last gun station and
keep it open while starting the pump.
3. Open the hydraulic supply line shutoff valve (W).
4. Run the pump until all air is purged from the fluid
lines.
5. Count the cycle rate of the pump.
6. Close the flow control valve until the cycle rate and
fluid pressure start to drop.
7. Open the flow control valve slightly until the cycle
rate and fluid pressure return to the desired level.
This method of setting the hydraulic controls
ensures proper pump operation and will prevent
pump runaway and damage if the fluid supply runs
out.
8. Adjust the fluid pressure to the lowest setting
necessary to get the desired results. Higher pres-
sures may not improve the spray pattern and will
cause premature component wear.
9. To adjust the spray pattern, follow the complete
instructions in your gun manual.
10. One at a time, open any other guns in the system
to purge air from the lines.
NOTE: In a circulating system, the pump will continue
to cycle as long as hydraulic fluid is supplied. 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 serious injury, in-
cluding splashing in the eyes or on the
skin, and property damage, never ex-
ceed the maximum air/hydraulic and fluid working
pressure of the lowest rated component in your
system. See EQUIPMENT MISUSE HAZARD,
System Pressure, on page 3 and Technical Data
on page 22.
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 con-
tainer and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.
Shutdown
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
For overnight shutdown, stop the pump at the bottom
of its stroke to prevent fluid from drying on the ex-
posed displacement rod and damaging the throat
packings. Relieve the pressure.
Always flush the pump before the fluid dries on the
displacement rod. See Flushing on page 13.

310570 13
Maintenance
Preventive Maintenance Schedule
The operating conditions of your particular system
determine how often maintenance is required. Estab-
lish a preventive maintenance schedule by recording
when and what kind of maintenance is needed, and
then determine a regular schedule for checking your
system.
