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. 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.

Y

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.

Hydraulic power supply: 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.

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.

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 thor­oughly before connection to the motor.

2. Plug hydraulic inlets, outlets, and line ends when
disconnecting them for any reason.

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., 37° flare. Use a minimum 1/2 in. (13
mm) ID hydraulic supply line (L).

• For Viscount II motors, use a minimum 13 mm (1/2
in.) ID supply line (L). The motor has a 3/4 npt(f)
hydraulic oil supply fitting.

• For Viscount II motors, use a minimum 22 mm (7/8
in.) 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.

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.

• 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 on page 9.

• Fluid filter: with a 60 mesh (250 micron) stainless
steel element to filter particles from the fluid as it
leaves the pump.

relieve fluid pressure in the hose and gun.

• Fluid shutoff valve (D): shuts off fluid flow.

• 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 over­pressurizing 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.

Operation

Operation

Pressure Relief Procedure

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.

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
overpressurizing the motor or its seals. When starting
the hydraulic system, open the return line shutoff
valve first.

7. 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.

8. 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
motor changes over.

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 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 tight­ened securely.

4. Start the hydraulic power supply.

5. Open the return line shutoff valve (R), then the sup­ply 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.

IG

. 4 on page 13.

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.

Shutdown

Follow Pressure Relief Procedure, page 11.

Always flush the pump before the fluid dries on the dis­placement rod. See Flushing on page 12.

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.

Mix Tank Volume

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.

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.

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 manufac­turer's recommendations on reservoir and filter cleaning,
and periodic changes of hydraulic fluid.

12 3A0537G

Maintenance

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

. 4.

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.
