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.
WARNING
A bleed-type master air valve (D) and a fluid drain
valve (E) are required in your system, to help re-
duce 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.
Air Line Accessories
Install the following accessories in the order shown in
the Typical Installation, using adapters as necessary:
DAn air line lubricator (B) provides automatic air
motor lubrication.
DA 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.
DAn 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.
DAn air line filter (C) removes harmful dirt and
moisture from the compressed air supply.
DA 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).

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. 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 sys-
tem) to relieve all fluid pressure, having a contain-
er 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 com-
patible 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.

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/dispens-
ing 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 acceler-
ates 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.

Operation
Corrosion Protection for 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 or oil-based
solvent, relieve pressure, and leave the mineral spir-
its in the pump. Be sure to follow the Pressure Re-
lief Procedure Warning at left.
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
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 7.
1. Relieve the pressure.
2. Check all other possible remedies before disas-
sembling the pump.
