Installation
Grounding
The equipment must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for the electrical current
due to static build up or in the event of a short circuit.
Pump: use a ground wire and clamp (Y). See FIG. 1.
Loosen the grounding lug locknut (W) and washer.
Insert one end of the ground wire into the slot in the lug
and tighten the locknut securely. Connect the ground
clamp to a true earth ground. Order Part No. 237569,
Ground Wire and Clamp.
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 nonconductive surface, 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
firmly to the side of a grounded metal pail, then trigger
the gun.
Stand Mount
Order Part No. 253692 Pump Stand Kit (accessory).
Mount the pump in the pump stand and secure with the
four screws and lockwashers supplied in the kit.
See Mounting Hole Layouts on page 17. Secure the
stand to the floor with M19 (5/8 in.) bolts which engage
at least 152 mm (6 in.) into the concrete floor to prevent
the pump from tipping.
F
IG. 1. Ground Wire
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 total resistance to
ground exceeds 25 megohms, replace hose immediately.
Air compressor: follow manufacturer’s recommendations.
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.
Wall Mount
Order Part No. 255143 Wall Bracket Kit (accessory).
1. Ensure the wall is strong enough to support the
weight of the pump assembly and accessories, fluid,
hoses, and stress caused during pump operation.
2. Ensure that the mounting location has sufficient
clearance for easy operator access.
3. Position the wall bracket at a convenient height,
ensuring that there is sufficient clearance for the
fluid suction line and for servicing the lower.
4. Drill four 7/16 in. (11 mm) holes using the bracket as
a template. Use either of the two mounting hole
groupings in the bracket. See Mounting Hole Lay-
outs, page 17.
5. Bolt the bracket securely to the wall using bolts and
washers designed to hold in the wall’s construction.
6. Attach the pump assembly to the mounting bracket.
7. Connect air and fluid hoses.

Installation
Plumbing
See FIG. 2. Install a fluid shutoff valve (D) between the
mix tank (A) and the pump.
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 contaminating your fluid with oil, flush the equipment with a
compatible solvent before using the equipment. See
Flushing, page 9.
Accessories
Install the following accessories in the order shown in
F
IG. 2, using adapters as necessary.
Air Line
• Pump air regulator (L): to control pump speed and
outlet pressure. Locate close to the pump.
• Air line filter (K): removes harmful dirt and moisture from compressed air supply.
• Second bleed-type air valve (H): isolates air line
accessories for servicing. Locate upstream from all
other air line accessories.
Fluid Line
• 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.
• Fluid shutoff valve (D): shuts off fluid flow.
• 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.
Trapped air can cause the pump to cycle unexpectedly, which could result in serious injury from splashing 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 overpressurization, do not
exceed the maximum air inlet pressure rating to the
air motor (see page 2). 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
Operation
Pressure Relief Procedure
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. Leave
drain valve(s) open until you are ready to pump
again.
Prime the Pump
1. Fill the TSL reservoir to the Maximum fill line with
Throat Seal Liquid (TSL). See F
NOTE: During operation the TSL level in the reservoir
will fluctuate slightly at pump changeover.
2. Close pump air regulator (L) by turning knob counterclockwise reducing pressure to zero. Close
bleed-type air valve (M). Also verify that all drain
valves (N) are closed.
3. Connect air line (J) to bleed type air valve (M).
4. Check that all fittings throughout system are tightened securely.
IG. 3 on page 10.
9. Verify that pump actuations are priming the pump
wet-cup. If not, confirm that the TSL pump piston is
being depressed at bottom changeover, and that
reservoir check valves are not stuck closed.
10. Close the fluid shutoff valve (D) downstream of the
pump. The pump should stall against pressure.
NOTE: In a circulation system, the pump operates continuously until the power supply is shut off. In a
direct-supply system, the pump starts when the dispense valve is opened, and stops when the dispense
valve is closed.
Stop the Pump at the Bottom of Its Stroke
Relieve the pressure when you stop the pump for any
reason. Stop the pump on the downstroke, before the air
motor changes over.
NOTICE
Failure to stop the pump at the bottom of its stroke
allows fluid to dry on the piston rod, which can damage the throat packings and the TSL pump piston seal
when the pump is restarted.
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.
7. Open bleed-type air valve (M). Slowly turn pump air
regulator (L) clockwise, increasing pressure until
pump starts.
8. Cycle pump slowly until all air is pushed out and
pump and hoses are fully primed.
8 3A1450D
Shutdown
Follow Pressure Relief Procedure, page 8.
Always flush the pump before the fluid dries on the displacement rod. See Flushing on page 9.
Maintenance
Maintenance
Preventive Maintenance Schedule
The operating conditions of your particular system
determine how often maintenance is required. Establish
a preventive maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your system.
Your maintenance schedule should include the following:
Flushing
• Flush before changing colors, before fluid can dry in
the equipment, at the end of the day, before storing,
and before repairing equipment.
• Flush at the lowest pressure possible. Check connectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
Stall Test
Perform a stall test periodically to ensure the piston seal
is in good working condition and prevent system overpressurization:
Close the fluid shutoff valve (D) closest to the pump on
the downstroke and be sure that the pump stalls. Open
the fluid shutoff valve to restart the pump. Close the fluid
shutoff valve (D) closest to the pump on the upstroke
and be sure that the pump stalls.
NOTICE
Do not allow the pump to run quickly for a long period
of time as this may damage the packings.
Air Line Filter
Drain and clean as necessary.
Mix Tank Volume
Do not let the mix tank run dry. When the tank is empty,
the pump demands more power as it tries to suck in
some fluid. This causes the pump to run too fast, which
can seriously damage the pump.

Changing the TSL
Check the condition of the TSL and the level in the reservoir every week, minimum. TSL should be changed at
least every month.
Part No. 206995 Throat Seal Liquid (TSL) carries residue from the pump rod into the reservoir. Discoloration
of the TSL fluid is to be expected during normal operation. After some time the TSL will thicken and darken,
and must be replaced. Thick, dirty TSL will not pump
through the lines and will harden in the pump wet-cup.
How long TSL lasts depends on which chemicals are
used, how much is used, what pressure, and condition
of the pump seal and rod.
A drop in the level of TSL in the reservoir indicates that
the throat packings are starting to wear. Add TSL to the
reservoir and keep the level above the Minimum fill line.
Monitor the usage and condition of the TSL. If pumped
material bypasses the throat packings and enters the
TSL reservoir, replace the packings.
To change the TSL:
1. Shut off the pump.
To avoid the buildup of static charge, do not rub the
plastic bottle with a dry cloth while it is attached to the
pump. Remove the bottle to clean, if needed.
2. Remove and empty the reservoir bottle. Clean any
residue.
3. Clean screen (Z) of inlet check valve (VI). If check
valves are not sealing and dirty TSL is getting into
the wet-cup, replace the check valves (VI, VO). See
F
IG. 3.
4. Fill the reservoir to the Maximum fill line with Throat
Seal Liquid (TSL).
5. Run pump. Each time pump rod reaches bottom of
stroke, check that some TSL is pumped from reservoir through wet-cup and back to reservoir.
