Positioning the Unit
WARNING
Select a convenient location for the unit. The air
valves for the pump (37) and agitator (5) must be fully
accessible.
System Accessories
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 4.
WARNING
Proper grounding is an essential part of maintaining a
safe system.
A bleed-type master air valve (N) and a fluid drain
valve (K) are required in your system. These
accessories 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 adjust-
ing or repairing the pump or agitator.
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. A red–handled bleed–type ball valve is
supplied to relieve air trapped in the air motor.
The fluid drain valve assists in relieving fluid pres-
sure in the displacement pump, hose, and gun.
Triggering the gun to relieve pressure may not be
sufficient. Order Part No. 210071.
To reduce the risk of static sparking, the mounting
cover and all electrically conductive objects or devices
in the spray area must be properly grounded. Check
your local electrical code for detailed grounding
instructions for your area and type of equipment.
Agitator and drum cover: Connect one end of the
ground wire (Y) to the ground connector (X) on the rim
of the drum cover. See Fig. 1. Connect the other end
of the ground wire to a true earth ground. See the
pump instruction manual (307986 for 230992, 307985
for model 230993, or 308793 for model 220575) for
instructions on grounding the pump.

Air and fluid hoses: Use only electrically conductive
hoses with 500 ft. (150 m) maximum combined hose
length to ensure grounding continuity.
Air compressor: Follow manufacturer’s recommenda-
tions.
Spray gun or dispensing valve: Ground through con-
nection to a properly grounded fluid hose and pump.

tested with lightweight oil, which is left in to protect the
pump parts. If the fluid you are using may be contami-
nated by the oil, flush it out with a compatible solvent.
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:
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
D are instructed to relieve the pressure,
D stop spraying,
To clean any settled particles out of the system, flush
the entire system at least once each 90 days or less. If
possible, circulate the solvent and leave it in the lines
for two days, such as over the weekend, to help loosen
any dried paint.
D check or service any of the system equipment,
D or install or clean the spray nozzle.
1. Relieve the pressure.
1. Lock the gun trigger safety.
2. Shutdown the system as explained in Shutdown
and Care of the Pump on page 9.
2. Shut off the air supply to the pump.
3. Close the bleed-type master air valve (required in
your system). On Model 230992, this is the red–
handled ball valve, assembled next to the air
regulator.
3. Start the pump and operate it at about 30 cycles
per minute.
4. Lubricate the agitator, if you haven’t already done
so, and then close its air valve to stop agitation.
4. Unlock the gun trigger safety.
5. Hold a metal part of the gun firmly to the side of a
grounded metal pail, and trigger the gun to relieve
pressure.
WARNING
Failure to shut off the agitator before raising the
pump assembly may result in serious injury from
splashing paint in the eyes or contact with the
blades of the agitator.
6. Lock the gun trigger safety.
7. Open the drain valve (required in your system),
and have a container ready to catch the drainage.
8. Leave the drain valve open until you are ready to
spray again.
5. Raise the pump out of the paint while it is still
running and let it run itself dry to force the paint
back into the drum. Shut off the pump.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, very slowly loosen the
tip guard retaining nut or hose end coupling and relieve
the pressure gradually. Then loosen it completely.
Then clear the tip or hose.
CAUTION
Never leave water or water-based fluid in the pump
overnight. Flush with a compatible solvent to protect
the parts from corrosion.
Flushing
WARNING
6. Remove the paint drum and place a 55 gallon
drum, containing enough solvent to thoroughly fill
and flush the system, under the pump. Lower the
pump.
FIRE AND EXPLOSION HAZARD
Before flushing, read the section FIRE
AND EXPLOSION HAZARD on page
4. Be sure the entire system and
flushing pails are properly grounded.
Refer to Grounding on page 5.
7. Start the pump again and allow the solvent to
circulate for at least one hour.

Operation
8. Shut off the air to the pump, open the bleed–type
5. When the paint returns through the return line in a
steady stream, turn on the air to one gun, open
both fluid shutoff valves (C) near the gun, and
adjust the fluid regulator (B). See the manuals
supplied with these components for pressure
range and adjustment . Repeat for all gun stations.
master air valve, and open the drain valve (K).
Leave the solvent in the system overnight or, if
possible, all weekend.
9. Start the pump and circulate it again for 30 min-
utes. Raise the pump out of the solvent and let it
dry to force out the solvent. Drain solvent from all
outlet loops and filters.
6. Paint line pressure is controlled by the back pres-
sure regulator (203). This regulator restricts flow of
paint in the line so there is sufficient paint pressure
at all gun stations. Turn the regulator handle
clockwise to increase and counter–clockwise
to decrease pressure.
10. Place the paint supply drum under the pump,
agitate the paint, install the gun and hoses.
11. Reset the air and fluid pressure regulators to
complete the system flushing.
Adjust the regulator so there is about 10 psi
(0.6 bar) more fluid pressure at the regulator
than is required at the last gun in the line.
Adjusting the Unit
Install supply drum under cover/pump. Make sure that
the cover is supported by the drum.
NOTE: As you increase fluid line pressure, you must
also increase air pressure to the pump, so the pump
can handle the heavier load. However, never increase
the pressure so much that you exceed the maximum
working pressure of any component in the system.
7. As you start to spray, adjust the air and fluid
pressures to the gun to obtain the best results.
CAUTION
Shortened or recycled drums may cause the pump
or agitator to bottom out in the drum, causing
damage. Contact your fluid supplier to order a
standard size drum.
1. Unscrew the filter bowl and remove the filter
screen. Replace the bowl. Flush the unit until
clear solvent comes from the gun, then reinstall
the filter screen.
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.
2. Before operation, ensure that all fasteners and
tube connections are tightened securely.
Starting and Adjusting the Pump
1. Close the air regulator (204).
2. Start the agitator (3). Agitate the paint just fast
enough to keep all paint particles suspended.
Over–agitating causes air bubbles in the paint
which can cause poor gun performance and poor
surface finish.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your system, which could cause compo-
nent rupture and serious injury, never
exceed the specified Maximum Incoming Air Pres-
sure to the pump. (see Technical Data on
page 15.)
3. Open the red–handled ball valve. Open the pump’s
bleed-type master air valve (N).
4. Slowly open the air regulator until the pump starts.
Adjust it until the pump cycles slowly – about 50
cycles per minute.

4. Open the bleed–type master air valve (N), and the
Shutdown and Care of the Pump
pump air regulator (204) to restart the pump.
Circulate the paint to remove all trapped air before
shutting down.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 7.
5. Disconnect the gun’s fluid hose from the gun and
the fluid regulator. Plug the regulator outlet. Blow
compressed air and compatible solvent through
the hose to clean it. Clean the gun according to the
instructions supplied with it. Each month remove
and clean the fluid regulator.
Never allow paint to dry in the pump and lines.
To shutdown the system
1. Relieve the pressure. Stop the agitator, and
lubricate it.
6. If you are not using an air line lubricator, manually
lubricate the motor at least once a day.
2. If using a Graco fluid pressure regulator at the
gun, reverse its regulating key and thread it into
the regulator cap as far as it will go.
7. Circulate the fluid in the lines often enough during
the shutdown to prevent the paint from drying.
3. Loosen the spray gun air cap about three turns,
hold a rag over the front of the air cap and fully
trigger the gun. This forces paint in the gun, hose
and regulator back into the circulating line. Close
the fluid shutoff valves (C) at that gun station,
Repeat for the other gun stations.
NOTE: To drain the circulating lines and flush the
system, see Flushing on page 7.
