Installation
System Accessories
Refer to Fig. 2 and the Accessories section.
NOTE: To ensure maximum pump performance, be sure
that all accessories used are properly sized to meet your
system’s requirements.
Air Line Accessories
Install the following accessories in the order shown in the
Typical Installation, using adapters as necessary:
•An air line lubricator (B) provides automatic air
motor lubrication.
•A bleed-type master air valve (D) 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
air regulator.
•An air regulator (A) 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.
•An air line filter (C) removes harmful dirt and
moisture from the compressed air supply.
•A second bleed-type air valve (D) isolates the air
line accessories for servicing. Locate upstream from
all other air line accessories.
Fluid Line Accessories
A fluid drain valve (E) is required in your system to
relieve fluid pressure in the hose and gun (see the
WARNING at left). Install the drain valve pointing down,
but so the handle points up when the valve is opened.
CONNECT THE HOSES
Connect a grounded air supply hose (G) to supply air to
the pump’s 1/4 npt(f) air inlet (K). Connect a grounded fluid
hose (H) to the 1/2 npt(f) fluid outlet (M). In a circulating
system, remove the pipe plug and connect a fluid return
line to the 3/8 npt(f) return port (F). See Fig. 3 and the
Typical Installation drawing, Fig. 2.
To use Model 223954 in a fixed mounting, connect a
supply line to the 3/4 npt fluid inlet (J).
Fig. 3
WARNING
A bleed-type master air valve (D) and a fluid drain valve
(E) are required in your system, to help reduce the risk
of serious injury, including splashing 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 (D) relieves air trapped
between this valve and the pump after the pump is shut
off. Trapped air can cause the pump to cycle
unexpectedly and result in serious injury, including
amputation. Locate the valve close to the pump.
The fluid drain valve (E) helps relieve pressure in the
displacement pump, hose, and dispensing valve when
shutting off the pump. Actuating the dispensing valve to
relieve pressure may not be sufficient, especially if there
is a clog in the hose or the dispensing valve.

Operation
Pressure Relief Procedure
1. Shut off the air to the pump.
2. Close the bleed-type master air valve (required in
your system).
3. Hold a metal part of the dispensing valve firmly to the
side of a grounded metal pail, and trigger the valve to
relieve pressure.
4. Open the fluid drain valve (required in your system) to
relieve all fluid pressure, having a container ready to
catch the drainage.
5. Leave the drain valve open until you are ready to
dispense again.
If you suspect that the nozzle or hose is completely
clogged, or that pressure has not been fully relieved after
following the steps above, very slowly loosen the hose
end coupling and relieve pressure gradually, then loosen
completely. Now clear the nozzle or hose.
Flush the Pump Before Using
The pump was tested in lightweight oil, which was left in to
protect pump parts. To prevent contamination of the fluid
you are pumping, flush the pump with a compatible solvent
before using it.
To flush the pump, connect a short hose to the pump
outlet, insert the pump intake into a pail of compatible
solvent, direct the hose into a pail, and start the pump as
explained at right.
Cycle the pump slowly for at least 5 minutes, then stop and
disconnect the air hose. Push up on the ball of the intake
valve (J) to drain the lower part of the pump. See Fig. 4.
Turn the pump over to drain the upper part of the pump.
Fig. 4
Starting and Adjusting the Pump
1. Mount the pump and connect to a fluid supply as
explained on page 5.
2. See the INSTALLATION on page 6. Be sure the air
regulator (A) and bleed-type master air valve (D) are
closed.
3. Hold a metal part of the spray gun/dispensing valve
firmly to the side of a grounded metal pail and hold
the trigger open. Then open the pump’s bleed-type
master air valve (D). Now slowly open the air
regulator (A) until the pump starts.
4. Run the pump slowly until all the air is pushed out of
the pump and hose. Always use the lowest pressure
necessary to get the desired results. Higher
pressures waste fluid and cause premature system
wear.
5. After all the air is purged, release the gun/dispensing
valve trigger. In a direct supply system, the pump will
start and stop as the gun/valve is opened and closed.
In a circulating system, the pump will run continuously
and will speed up or slow down as supply demands,
until the air supply is shut off.
Never allow the pump to run dry of the fluid being pumped.
A dry pump will quickly accelerate to a high speed,
possibly damaging itself. If your pump accelerates quickly,
or is running too fast, stop it immediately and check the
fluid supply. If the supply container is empty and air has
been pumped into the lines, refill the container and prime
the pump and the lines with fluid, or flush and leave it filled
with a compatible solvent. Be sure to eliminate all air from
the fluid system.
Shutdown and Care of the Pump
For overnight shutdown, follow the Pressure Relief
Procedure Warning at left. Always stop the pump at the
bottom of the stroke to prevent the fluid from drying on the
exposed displacement rod and damaging the throat
packings.
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:
• are instructed to relieve the pressure,
• stop spraying,
• check or service any of the system equipment,
• or install or clean the spray nozzle.

Operation
Corrosion Protection for Pump Lubrication
If you are not using an accessory air line lubricator,
manually lubricate the motor daily. Disconnect the air
regulator, place about 15 drops of light machine oil in the
pump air inlet, reconnect the regulator and turn on the air
supply to blow oil into the motor.
Troubleshooting
1. Relieve the pressure.
2. Check all other possible remedies before
disassembling the pump.
CAUTION
Water, or even moist air, can cause your pump to
corrode. To help prevent corrosion, NEVER leave the
pump filled with water or air. After normal flushing, flush
the pump again with mineral spirits solvent (also called
white spirits) or oil-based solvent, relieve pressure, and
leave the mineral spirits solvent (also called white
spirits) in the pump. Be sure to follow the Pressure
Relief Procedure Warning at left.
WARNING
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 7.
