Installation
Grounding
Pump: use a ground wire and clamp (not included). See
FIG. 2. Remove the green ground screw (Z) from the
bottom of the air motor. Insert the screw through the
loop on the end of the ground wire (Y) and reattach the
screw to the air motor. Connect the ground clamp to a
true earth ground. Order Part No. 244524, Ground Wire
and Clamp.
Air and fluid hoses: use only electrically conductive
hoses with a maximum of 500 ft. (150 m) combined
hose length to ensure grounding continuity. Check the
electrical resistance of hoses. If the total resistance to
ground exceeds 25 megohms, replace hose immedi-
ately.
Air compressor: follow manufacturer’s recommenda-
tions.
Surge tank: use a ground wire and clamp.
Dispense valve: ground through a connection to a
properly grounded fluid hose and pump.
Fluid supply container: follow local code.
Object being sprayed: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a non-conductive sur-
face, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of the spray gun or
valve firmly to the side of a grounded metal pail, and
then trigger the gun or open the valve.
Mounting
The pump can be mounted using one of the following
options:
• Stand mount: Kit 253692
• Wall mount: Kit 255143
• Floor mount:
• Kit 19Y313—Complete kit
• Kit 19Y286—Plate for mounting to an existing
floor mount
Pump Mounting Kits manual 311619 describes the
mount parts and how to install each.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.

Installation
83A6938D
Plumbing
Install a fluid shutoff valve (D) between the mix tank (A)
and the pump (F).
When using a stainless steel pump, use stainless steel
plumbing to maintain a corrosion-resistant system.
Flush Before Using Equipment
The equipment was tested with lightweight oil, which is
left in the fluid passages to protect parts. To avoid con-
taminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Flushing the Fluid Supply Lines, page 11.
Accessories
Install the following accessories in the order shown in
FIG. 1, page 6, using adapters as necessary.
Fluid Line
See FIG. 1, page 6.
•Fluid shutoff valve (D): shuts off fluid flow.
•Fluid filter: with a 60 mesh (250 micron) stainless
steel element to filter particles from the fluid as it
leaves the pump.
•Fluid drain valve (N): required in your system, to
relieve fluid pressure in the hose and gun.
Air Line
See FIG. 1, page 6.
•Second bleed-type air valve (H): isolates air line
accessories for servicing. Locate upstream from all
other air line accessories.
•Air line filter (K): removes harmful dirt and mois-
ture from compressed air supply.
•Pump air regulator (L): to control pump speed and
outlet pressure. Locate close to the pump.
•Bleed-type master air valve (M): required in your
system to relieve air trapped between it and the air
motor when the valve is closed.
NOTICE
To prevent a bellows failure in a sealed 4-ball pump:
• Do not exceed fluid inlet pressure of 15 psi (0.1
MPa, 1.0 bar).
• Do not use a ball check pump on the inlet side of
this pump.
• Do not use a suction tube with a check valve on
the inlet side of this pump.
Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from splash-
ing or moving parts. Be sure the valve is easily
accessible from the pump and located downstream
from the air regulator. Be sure the air bleed hole
points away from the operator.
To help prevent fluid over pressurization, do not
exceed the maximum air inlet pressure rating to the
air motor (see page 27). If you can apply more than
the maximum air input pressure to the system, install
a safety relief valve between the bleed-type master
air valve and the air motor. The safety relief valve
must be set to open if the air inlet pressure to the
motor exceeds the motor rating.

Operation
3A6938D 9
Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
1. Close the bleed-type master air valve (M).
2. Open the dispensing valve, if used.
3. Open all fluid drain valves (N) in the system, having
a waste container ready to catch drainage.
4. Leave drain valve(s) open until you are ready to
pump again.
Prime the Pump
1. Fill the wet cup with Throat Seal Liquid (TSL).
NOTE: Sealed 4-ball lowers with bellows do not
require TSL.
NOTE: During operation the TSL level in the wet cup will
fluctuate slightly at pump changeover.
2. Close pump air regulator (L) by turning the knob
counterclockwise, reducing pressure to zero. Close
the bleed-type air valve (H). Also verify that all drain
valves (N) are closed.
3. Connect air line (J) to bleed type air valve (H).
4. Check that all fittings throughout system are tight-
ened securely.
5. Connect the fluid supply line (C) from the mix tank
shutoff valve (D) to the pump.
6. Connect the fluid line (E) to the pump outlet or surge
suppressor outlet (G), if used.
NOTE: If your pump has DataTrak, see your separate
XL air motor manual for DataTrak instructions.
7. DataTrak equipped units with runaway protection
only: enable the prime/flush function by pushing the
prime/flush button on the DataTrak.
8. Open bleed-type air valve (H). Slowly turn pump air
regulator (L) clockwise, increasing pressure until
pump starts.
9. Cycle pump slowly until all air is pushed out and
pump and hoses are fully primed.
10. DataTrak equipped units with runaway protection
only: disable the prime/flush function by pushing the
prime/flush button on the DataTrak.
11. Close the fluid shutoff valve (D) downstream of the
pump. The pump should stall against pressure.
NOTE: In a circulation system, the pump operates con-
tinuously until the power supply is shut off. In a
direct-supply system, the pump starts when the dis-
pense valve is opened, and stops when the dispense
valve is closed.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
splashing fluid and moving parts, follow the Pressure
Relief Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
NOTICE
Do not allow the pump to run quickly for a long period
of time as this may damage the packings.

Operation
10 3A6938D
Stop Pump at Bottom of Stroke
Relieve the pressure when you stop the pump for any
reason. Stop the pump on the down stroke, before the
air motor changes over.
Shutdown
Follow the Pressure Relief Procedure, page 9.
Always flush the pump before the fluid dries on the dis-
placement rod. See Flushing the Fluid Supply Lines
on page 11.
NOTICE
Failure to stop the pump at the bottom of its stroke
allows fluid to dry on the piston rod (R), which can
damage the throat seal.
