Care of Stainless Steel Waukesha Cherry-Burrell
Page 6 95-03057 11/2012
Care of Stainless Steel
Stainless Steel Corrosion Corrosion resistance is greatest when a layer of oxide film is
formed on the surface of stainless steel. If film is disturbed or
destroyed, stainless steel becomes much less resistant to
corrosion and may rust, pit or crack.
Corrosion pitting, rusting and stress cracks may occur due to
chemical attack. Use only cleaning chemicals specified by a
reputable chemical manufacturer for use with 300 series stainless
steel. Do not use excessive concentrations, temperatures or
exposure times. Avoid contact with highly corrosive acids such as
hydrofluoric, hydrochloric or sulfuric. Also avoid prolonged
contact with chloride-containing chemicals, especially in
presence of acid. If chlorine-based sanitizers are used, such as
sodium hypochlorite (bleach), do not exceed concentrations of
150 ppm available chlorine, do not exceed contact time of 20
minutes, and do not exceed temperatures of 104°F (40°C).
Corrosion discoloration, deposits or pitting may occur under
product deposits or under gaskets. Keep surfaces clean,
including those under gaskets or in grooves or tight corners.
Clean immediately after use. Do not allow equipment to set idle,
exposed to air with accumulated foreign material on the surface.
Corrosion pitting may occur when stray electrical currents come
in contact with moist stainless steel. Ensure all electrical devices
connected to the equipment are correctly grounded.
Elastomer Seal
Replacement Following
Passivation
Passivation chemicals can damage product contact areas of
WCB equipment. Elastomers (rubber components) are most
likely to be affected. Always inspect all elastomer seals after
passivation is completed. Replace any seals showing signs of
chemical attack. Indications may include swelling, cracks, loss of
elasticity or any other noticeable changes when compared with
new components.

Installation
Site Selection
Considerations Foundation & Drainage
The Votator II should be located on a firm foundation, angled to
allow liquids to drain away from the unit.
Clearances •Therear and sides of the unit, or unit cluster, should have
adequate clearance to provide easy access for maintenance.
•The
front of the Horizontal unit should have the following
minimum clearances to allow for removal of the mutator
shaft:
6 x 84 Votator II - 102 in (259 cm)
6 x 72 Votator II - 90 in (230 cm)
6 x 48 Votator II - 71 in (180 cm)
6 x 36 Votator II - 59 in (150 cm)
6 x 24 Votator II - 40 in (102 cm)
•The
bottom of the Vertical unit should have the following
minimum clearances to allow for removal of the mutator
shaft:
6 x 84 Votator II - 96 in (244 cm)
6 x 72 Votator II - 84 in (214 cm)
6 x 48 Votator II - 66 in (168 cm)
6 x 36 Votator II - 54 in (137 cm)
6 x 24 Votator II - 48 in (122 cm)
Leveling the Unit The Horizontal Votator II should be leveled lengthwise (along the
length of the cylinder) and crosswise by adjusting the feet on the
legs.
For units that will perform CIP, set the level for a forward pitch of
0.3 degrees (1/16 inch per foot).
If CIP is not required, set the level to what will give the best
drainage for the cylinder.
Electrical Power
Connections The following electrical components for the Votator II require
connection in accordance with the electrical schematics in this
manual, tagged vendor specifications, and local regulations:
DANGER: The Votator II operates
with high voltage. Electrical work
should be performed by a
Licensed Electrician in
accordance with local regulations.
• Drive Motor
Each cylinder is furnished with a 3-phase, multi-voltage gear
motor with a horsepower rating per the application:
Std. Votator II accepts 7-1/2 HP (5.5 kW), 10 HP (7.5 kW), 15
HP (11kw) or 20 HP (15 kW); Extra Heavy Duty Votator II
accepts 25HP (18.8 kW), 30 HP (22.5 kW) or 40 HP (30 kW).
Motor is fixed speed and suitable for use with a variable fre-
quency controller.
•Hydraulic Pump Motor (Vertical units only)
A 3/4 (0.5 kW) horsepower, fixed speed motor. A variable fre-
quency controller should not be used for this motor.

Installation Waukesha Cherry-Burrell
Page 10 95-03057 11/2012
•Refrigeration Valves:
liquid feed solenoid valve
dual pressure regulating valve
level switch
hot gas pressure regulating valve
hot gas solenoid valve
•Freeze Protection Components (if furnished):
current sensing relay
instrument current transformer
digital current indicator
Mutator Rotation Check Correct mutator shaft rotation is counterclockwise when looking
down the unit from the drive end (indicated by a sticker located
near the motor). To check for correct rotation, momentarily start
the drive motor and observe the rotation of the shaft in the back
of the unit.
If rotation of the shaft is incorrect, the drive motor is wired
incorrectly. Have a Licensed Electrician change the wiring so the
rotation of the shaft is correct.
Mechanical Seals
Figure 2 - Single Mechanical Seal
Figure 3 - Double Mechanical Seal
The Votator II is furnished with either a single or double
mechanical seal on both ends of the mutator shaft. Units
furnished before 2005 were installed with either a single or
double mechanical seal configuration. See “2005 Mechanical
Seal Design” on page 11 for units furnished between 2005 and
2012. See “2012 Mechanical Seal Design” on page 11 for
standard units finished from 2012 to the present. Certain
Votator II units have also been supplied with a special "Ball-lock
Mechanical Seal" or a "Packing Gland" instead. Consult your
order documentation to verify the specific seal configuration for
each Votator II unit.
Single Mechanical Seal
The single mechanical seal is normally not flushed but it can be. It
is shipped with a lip seal (See Figure 2) designed to contain water
or a liquid flush. The spring in the seal must be removed and the
seal reinstalled with the lip in the relief position to allow flushing.
This will minimize any damage to the contact surface on the stub
end of the shaft.
When the single mechanical seal is rotating, there must be
product or water flow to provide cooling to the rotating surfaces to
avoid permanent damage to the seal assembly.
If the seal is flushed, the fluid flow should be in the range of 5 to
10 gallons per hour and not exceed 5 psig. Piping to seals should
be in the bottom of head and out the top and with parallel flow,
never in series.
Double Mechanical Seal
The double mechanical seal is furnished with a primary seal for
product and a secondary seal to contain a steam or water flush.

Waukesha Cherry-Burrell Installation
11/2012 95-03057 Page 11
2005 Mechanical Seal Design
Units furnished between 2005 and 2012 have a one-piece
chrome-oxide coated rotating body running against a stationary
ceramic head insert. It can easily be converted to a double
mechanical seal by adding secondary components to contain a
steam or water flush.
Figure 5 - Double Mechanical Seal
2012 Mechanical Seal Design
Standard units furnished starting in 2012 have removable rotary
seal faces in solid carbon, silicon carbide, tungsten carbide, and
narrow-face tungsten carbide materials. The stationary seal faces
are made of solid ceramic or silicon carbide. Like the 2005
design, the 2012 single mechanical seal can be converted to a
double mechanical seal by adding secondary components to
contain a water or steam flush.

Installation Waukesha Cherry-Burrell
Page 12 95-03057 11/2012
Flush Fluid Requirements
The double mechanical seal must be flushed, using the
threaded flush ports, anytime the mutator shaft is rotated. Failure
to do this will result in rapid seal failure due to excessive
contaminate and heat buildup.
The fluid flow should be in the range of 5 to 10 gallons per hour,
at a typical temperature of 80°F - 120°F (25°C - 49°C). Fluid
composition and temperature should be selected to dissolve or
suspend any product leakage and cool the mechanical seal
faces, and should also be compatible with the sealing o-ring
material. Piping to seal cavities for horizontal units should be in
the bottom of head and out the top, piped with parallel flow, never
with multiple seal cavities in series flow.
Piping Guidelines for Piping
Refer to the general assembly drawings in this manual for jacket
connection sizes and locations, and suggested media piping
drawings.
• Support ALL piping independently.
• Provide for line expansion and contraction.
• Install a safety valve to protect jacket.
• Provide temperature indicators on both sides of Votator II
unit.
• Provide pressure gauge on discharge side of pump.
• When using liquid coolant, provide a method to introduce
heating media into jacket to thaw overcooled product.
• Provide liquid coolant system bypass line around unit to allow
coolant system to be brought down to operating temperature
without circulating coolant through jacket.
Suggested Media Piping
for Steam The steam solenoid is opened, which lets pressure controlled
steam from the boiler into the jacket. A temperature sensor
monitors the temperature of the product and regulates the steam
flow to achieve the required temperature. Heating of the product
takes place when the steam condenses into water from the
transfer of heat through the jacket.
CAUTION: The safety valve
should be installed on the
discharge side of product pump
for safety and equipment
protection.
DANGER: Do not install any
positive shutoff valves
downstream of the Votator II unit.
WARNING: Do not allow a
volume of liquid to become
isolated in the jacket without
relief protection. Thermal
expansion created as liquid
warms can generate enough
force to crush tube, causing
damage to internal components
and drive system.

Suggested Media Piping
for Water or Liquid The media piping should flow counter-current to the product flow,
and should be circulating at a rate of 50 gpm. The suggested
arrangement automates the source flow to the actual heat
exchange requirements to provide maximum control of the
process.

Refrigeration Piping
Installation Analyze plant refrigeration load capacity thoroughly. The system
must be sized to adequately support the additional capacity of
this cylinder. All pipes must be clean and free of oil, chips and
sealant residue. Excessive residue in plant piping can foul and
clog cylinder refrigeration valves and components, causing costly
delays in start-up. Refer to appropriate piping schematic in this
manual for Liquid Overfeed (LOF) or Gravity Refrigeration
System.
WARNING: Ammonia or Freon
lines should be installed by fully
trained and qualified Refrigeration
Piping Specialists.
Liquid Line Installation
The liquid line should be installed to provide a constant and
steady flow of liquid. Check with system requirements and plant
capacities to ensure that refrigeration piping is sized properly.
Suction Line Installation
All Votator II refrigeration units operate best when provided with
constant suction pressure. To ensure constant pressure do the
following:
• Size suction header for at least 50% above rated capacity of
cylinder.
• Do not connect to a header already in use by other
equipment with widely varying loads.
CAUTION: A suction trap or
auxiliary receiver should be
installed in the line to prevent
carry-over back to compressor.
• Insulate any suction line that passes through a cold room to
prevent condensate formation. Install a trap or auxiliary
receiver in the line.
• Keep suction pressure at compressor as low as possible.
(Lower pressure allows greater cooling capacity.)
Hot Gas Line (if required)
Review the following guidelines when connecting a hot gas line to
the system:
• Connection of a hot gas line should be from compressor high
side of line past oil trap or separator to minimize drawing in
oil.
• DO NOT run line through a cold room or beside a cold
suction line.
• Slope line away from equipment at 1/8 inch per foot (1 mm
per 100 mm) minimum.
• Install a strainer or filter in addition to recommended shut-off
valves and pressure gauge.
DANGER: Never install a shut-off
valve on this line. Never vent or
connect relief line back to suction
line.
Pressure Relief Line
The pressure relief line MUST be exhausted to the outside of the
building.
CAUTION: The relief valve is
factory set for appropriate
pressure and never needs
adjusting.
Never cap relief line or tie back to suction line.

Refrigeration Valves Liquid Feed Solenoid Valve
Liquid Feed Solenoid Valve is for on/off control of liquid
refrigerant flow. Valve is closed when de-energized.
Dual Pressure Regulating Valve
Dual Pressure Regulating Valve is shipped loose for installation
in vapor line on discharge side of refrigeration piping. Valve
regulates high-pressure for internal relief and low-pressure with
on/off solenoid valve for process control. It can be furnished for
manual regulating, pneumatic control with clean, dry, and oil free
air from 0-60 psig, or with a 115 volt motor mounted on the
regulating pilot that responds to a 4-20 milliamp electrical signal.
When using air, a decrease in pressure will lower the inlet
pressure producing a lower temperature.
Sporlan Level Master Control (LMC) or Level
Switch
Gravity Systems with Accumulator are furnished with a Sporlan
Level Master Control (LMC) or a Level Switch.
The LMC is a thermostatic expansion valve with a 15-watt heater
element. As the level in the accumulator drops, the electrically
added heat increases the pressure within the thermostatic
element and opens the valve. As the liquid level rises, the
electrical input is balanced by the heat transfer from the bulb to
the liquid refrigerant and modulates or shuts off the liquid flow.
Minor adjustments in the level response can be made by
adjusting the spring tension of the expansion valve seat.
If a refrigerant level float switch is provided, single or double
depending upon specifications, it is used to control the
accumulator level by opening or closing a solenoid operated
refrigeration valve. These systems contain that valve and an
expansion valve with a flow indicating scale.
Refrigerant Return Valve
Some Horizontal Votators have a solenoid operated Refrigerant
Return Valve that is in the closed position when the solenoid is
de-energized. This valve is used to stop the cooling process and
is closed if hot gas is applied.
High capacity freon systems have two solenoid valves: one for
hot gas to activate the return valve, the other to bleed the gas to
the suction line.
Flow Control Valves
Liquid Overfeed (LOF) or Pumped Refrigeration Systems have a
manually adjusted Flow Control Valve with setting scale for
refrigerant flow to each Votator cylinder. This valve maintains a
constant flow of liquid to the Votator and can serve as a check
valve to prevent back flow of liquid during hot gas.
The indicator scale on the valve corresponds to the refrigeration
tonnage. The regulator is set by multiplying the tonnage load by
the desired re-circulation rate. For example, if the refrigeration
load is 10 tons and 200% (3:1) overfeed is desired, the valve
should be set at 30 on the scale reading.

Hot Gas Pressure Regulating Valve
Systems with hot gas include a solenoid-operated Pressure
Regulating Valve for introducing and maintaining constant
downstream pressure for hot gas inlet.
Pumped Refrigeration Systems include a solenoid operated Hot
Gas Purge Valve for each Votator hot gas discharge line.
Pressure Relief Valve
DANGER: Never install a shutoff
valve in a relief line. This valve is located on the accumulator and should be
exhausted to outside the building. The valve is factory set to
relieve at the design pressure of the accumulator.
Suggested Media Piping
for Liquid Over Feed
Refrigeration
The liquid feed solenoid valve, when opened, allows liquid
refrigerant to flow into the jacket of the heat exchanger. The flow
is regulated by a manually set flow control valve. Cooling is
achieved when the pressure control valve is opened, causing the
pressure in the jacket to be reduced. This causes the liquid
refrigerant to change phase, absorbing heat from the heat
exchanger tube and product. The cooling rate is controlled by the
back pressure on the system and stops when the valve is closed.
Hot gas is used to push all of the remaining liquid from the
system into the ammonia low pressure receiver and quickly warm
the system. The low pressure receiver in the compressor room is
designed to separate the liquid from the vapor before re-
compressing.

Suggested Media Piping
for Gravity Refrigeration Liquid refrigerant from the receiver is stored in a surge drum
located above the Votator II. The level in the surge drum is
automatically controlled by the level system provided with the
equipment. Gravity forces the refrigerant into the cooling jacket
where it comes into contact with the heat transfer tube. The warm
product causes a portion of the liquid refrigerant to change
phase, causing the heat transfer tube and the product to be
cooled. The cooling rate is controlled by the refrigerant back
pressure, and hot gas can be used to push the liquid refrigerant
from the Votator cylinder and rapidly warm the system.
NOTE: Set high pressure regulating valve 5 to 10 psi higher than
outlet pressure of hot gas pressure reducing valve and lower than
the relief setting.
