Installation
Grounding
Pump: use a ground wire and clamp. See FIG. 1 Loosen
the locknut (W) of the grounding lug (Z). Insert one end
of the wire (Y) in the ground lug and tighten the locknut
securely. Connect the ground clamp to a true earth
ground. Order Part No. 237569, 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 total resistance to
ground exceeds 25 megohms, replace hose immedi-
ately.
Hydraulic power supply: follow manufacturer’s recom-
mendations.
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, then
trigger the gun or open the valve.
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.

83A3381E
Accessories
Install the following accessories in the order shown in
FIG. 2, using adapters as necessary.
Hydraulic Power Supply
Be sure the power supply can provide sufficient power to
the motor. Be sure the power supply is equipped with a
suction filter to the hydraulic pump.
Hydraulic Supply Line
• For Viscount I Plus motors, the hydraulic inlet on the
motor is 3/4 in. (20mm), 37° flare. Use a minimum
1/2 in. (13 mm) ID hydraulic supply line (L).
• For Viscount II motors, use a minimum 1/2 in.
(13 mm) ID supply line (L). The motor has a 3/4in.
3/4 in. (20mm) npt(f) hydraulic oil supply fitting.
•Supply line shutoff valve (S): isolates the motor
when servicing the system.
•Hydraulic fluid pressure gauge (P): monitors the
hydraulic oil pressure to the motor to avoid
over-pressurizing the motor or lower.
•Pressure- and temperature-compensated flow
control valve (T): prevents the motor from running
too fast, which can damage it. Pressure reducing
valve (N), which has a drain line (M) running to
the return line (K): controls the hydraulic pressure
to the motor.Hydraulic Return Line
• For Viscount I Plus motors, the hydraulic outlet on
the motor is 7/8 in.(22 mm), 37° flare. Use a mini-
mum 5/8 in. (16 mm) ID hydraulic return line (K).
• For Viscount II motors, use a minimum 7/8 in.
(22 mm) ID return line (K). The motor has a 1 in. npt
(f) hydraulic oil return fitting.
•Return line shutoff valve (R): isolates the motor
when servicing the system.
•Return fluid filter (J): removes residue from the
hydraulic fluid to help keep the system running
smoothly (10 micron size).
Fluid Line
For typical installation, see FIG. 2.
•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 (U): required in your system, to
relieve fluid pressure in the hose and gun.
•Fluid shutoff valve (D): shuts off fluid flow.
NOTICE
The hydraulic power supply must be kept clean at all
times to avoid damage to the motor and hydraulic
power supply.
1. Blow out hydraulic lines with air and flush thor-
oughly before connection to the motor.
2. Plug hydraulic inlets, outlets, and line ends when
disconnecting them for any reason.
NOTICE
To avoid damage to the pump, never use the return
line shutoff valve to control the hydraulic flow. Do not
install any flow control devices on the hydraulic return
line.

Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure when-
ever you see this symbol.
1. Shut off the hydraulic supply line valve (S) first, then
the return line valve (R).
2. Open the dispensing valve, if used.
3. Open all fluid drain valves (U) 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 wet cup with Throat Seal Liquid (TSL).
NOTE: Sealed 4 ball lowers with bellows do not require
TSL.
2. Close the flow control valve (T) by turning knob
counterclockwise reducing pressure to zero. Close
the supply line shutoff valve (S) and the return line
shutoff valve (R). Also verify that all drain valves (U)
are closed.
3. Check that all fittings throughout system are tight-
ened securely.
4. Start the hydraulic power supply.
5. Open the return line shutoff valve (R), then the sup-
ply line shutoff valve (S). Slowly turn the flow control
valve (T) clockwise, increasing pressure until pump
starts.
6. Cycle pump slowly until all air is pushed out and
pump and hoses are fully primed.
7. 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.
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
motor changes over.
Shutdown
Follow the Pressure Relief Procedure, page 11.
Always flush the pump before the fluid dries on the dis-
placement rod. See Flushing on page 12.
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
When shutting down the hydraulic system, always
shut off the hydraulic supply line shutoff valve (S) first,
and then the return line shutoff valve (R) to prevent
over pressurizing the motor or its seals. When starting
the hydraulic system, open the return line shutoff
valve first.
NOTICE
Failure to stop the pump at the bottom of its stroke
allows fluid to dry on the piston rod, which can dam-
age the throat packings when the pump is restarted.

Maintenance
12 3A3381E
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.
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 con-
nectors for leaks and tighten as necessary.
• Flush with a fluid that is compatible with the fluid
being dispensed and the equipment wetted parts.
Mix Tank Volume
Don't 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.
Hydraulic Power Supply Check
Carefully follow the hydraulic power supply manufac-
turer's recommendations on reservoir and filter cleaning,
and periodic changes of hydraulic fluid.
Stall Test
Perform a stall test periodically to ensure the piston seal
is in good working condition and prevent system pres-
surization:
Close the fluid shutoff valve (D) closest to the pump on
the down stroke 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.
Stop the pump on the down stroke, before the air motor
changes over.
Changing the TSL On Wet Cup
Models
On Wet Cup Models check the condition of the TSL and
the level in the reservoir every week, minimum. TSL
should be changed at least every month.
To avoid fire and explosion, always ground equipment
and waste container. To avoid static sparking and
injury from splashing, always flush at the lowest pos-
sible pressure.
NOTICE
Do not allow the pump to run quickly for a long period
of time as this may damage the packings.
NOTICE
Failure to stop the pump at the bottom of its stroke
allows fluid to dry on the piston rod, which can dam-
age the throat packings and the TSL pump piston seal
when the pump is restarted.

torque to 75-80 ft-lb (102-109 N•m).
f. Continue to step 2.
2. Assemble the coupling nut (5) over the piston rod
(R).
3. Orient the lower (2) to the motor (1). Position the
lower on the tie rods (3).
4. If you are reusing lock nuts (4) and the nylon of the
lock nut is worn or cut, add blue thread locker to the
tie rod threads.
5. Screw the lock nuts (4) onto the tie rods. Leave the
lock nuts (4) loose enough to allow the lower to
move so that it can be aligned correctly.
6. Tighten the mounting plate screws.
• Viscount I Plus motors: Torque the screws (13)
to 15-17 ft-lb (20-23 N•m)
• Viscount II motors: Torque the screws (13) to to
50-55 ft-lb (68-75 N•m).
7. Insert the collars (6) into the coupling nut (5).
Tighten the coupling nut onto the coupling adapter
(8). Torque to 90-100 ft-lb (122-135 N•m) to allow
the pump rod to align the lower on the tie rods.
8. Tighten the lock nuts and torque to 50-60 ft-lb
(68-81 N•m).
9. Models with Sealed Lowers: Install the shields (9)
by engaging the bottom lips with the groove in the
top plate. Snap the two shields together.
10. Flush and test the pump before reinstalling it in the
system. Connect hoses and flush the pump. While it
is pressurized, check for smooth operation and
leaks. Adjust or repair as necessary before reinstall-
ing in the system.
11. Reconnect the pump ground wire before operating.
