Disconnect Switch
If the unit has no plug, a separate disconnect switch
must be installed, or another alternate means to
disconnect power must be implemented.
Water Connections
(Water Cooled Units, Only)
An adequate cold water supply must be provided
with a hand shut-off valve. The water inlet and drain
connections are located on the right side or the
underside of the base. These connections are either
3/8” or 1/2” FTP, depending on the model of the unit.
(Refer to “Model Specifications”.)
Flexible lines are recommended, if local codes
permit. In Europe, hose sets for connection of
appliances to the water mains must comply to the
international IEC 61770 standard.
The water expansion valve setting should be set at
255 PSIG (1758 kPa).
Depending on local water conditions, it may be
advisable to install a water strainer to prevent
foreign substances from clogging the automatic
water valve. There will be only one water “in” and
one water “out” connection.
DO NOT install a hand shut-off valve on the water
“out” line! Water should always flow in this order:
first, through the automatic water valve; second,
through the condenser; and third, through the outlet
fitting to an open trap drain.
A back flow prevention device is
required on the incoming water connection side.
Please refer to the applicable National, State, and
local codes for determining the proper configuration.
Refrigeration
In consideration of our environment, Taylor uses
only earth friendly HFC refrigerants. The HFC
refrigerant used in this unit is R404A. This
refrigerant is generally considered nontoxic and
nonflammable, with an Ozone Depleting Potential
(ODP) of zero (0).
However, any gas under pressure is potentially
hazardous and must be handled with caution.
NEVER fill any refrigerant cylinder completely with
liquid. Filling the cylinder to approximately 80% will
allow for normal expansion.
Use only R404A refrigerant that conforms
to the AHRI standard 700 specification. The use of
any other refrigerant may expose users and
operators to unexpected safety hazards.
Refrigerant liquid sprayed onto the skin may
cause serious damage to tissue. Keep eyes and skin
protected. If refrigerant burns should occur, flush
immediately with cold water. If burns are severe,
apply ice packs and contact a physician
immediately.
Taylor reminds technicians to be cautious of
government laws regarding refrigerant recovery,
recycling, and reclaiming systems. If you have any
questions regarding these laws, please contact the
factory Service Department.
WARNING: R404A refrigerant used in
conjunction with polyolester oils is extremely
moisture absorbent. When opening a refrigeration
system, the maximum time the system is open must
not exceed 15 minutes. Cap all open tubing to
prevent humid air or water from being absorbed by
the oil.
Main Compressor:
Air cooled units: 40 oz (1,134 g) of R404A.
Water cooled units: 38 oz (1,077g) of R404A.
Gear Alignment and Rear Shell Bearing
1. Make certain the drive shaft(s) can easily slide
in and out of the female socket on the gear
unit(s).
2. If a drive shaft is binding, the gear unit could be
out of alignment (loose). Check the bolts on the
gear unit to be sure they are tight.
3. Inspect the rear shell bearing for tightness. Be
sure the locking tab has been folded over to
prevent the nut from loosening.

Models C712/C713 Introduction
Compressor Warranty Disclaimer
The refrigeration compressor(s) on this machine are
warranted for the term indicated on the warranty
card accompanying this machine. However, due to
the Montreal Protocol and the U.S. Clean Air Act
Amendments of 1990, many new refrigerants are
being tested and developed, thus seeking their way
into the service industry. Some of these new
refrigerants are being advertised as drop-in
replacements for numerous applications. It should
be noted that in the event of ordinary service to this
machine's refrigeration system, only the refrigerant
specified on the affixed data label should be used.
The unauthorized use of alternate refrigerants will
void your compressor warranty. It will be the owners'
responsibility to make this fact known to any
technicians they employ.
It should be noted that Taylor does not warrant the
refrigerant used in its equipment. For example, if the
refrigerant is lost during the course of ordinary
service to this machine, Taylor has no obligation to
either supply or provide its replacement either at
billable or unbillable terms. Taylor does have the
obligation to recommend a suitable replacement if
the original refrigerant is banned, obsoleted, or no
longer available during the five year warranty of the
compressor.
Taylor will continue to monitor the industry and test
new alternates as they are being developed. Should
a new alternate prove, through our testing, that it
would be accepted as a drop-in replacement, then
the above disclaimer would become null and void.
To find out the current status of an alternate
refrigerant as it relates to your compressor, call the
local Taylor Distributor or the Taylor Factory. Be
prepared to provide the model/serial number of the
unit in question.

Power Switch
When placed in the ON position, the power switch
allows control panel operation.
Fluorescent Display
The fluorescent display is located on the front
control panel. During normal operation, the display is
blank. The display is used to show menu options
and notifies the operator if a fault is detected. On
International models, the display will indicate the
temperature of the mix in each hopper.
Indicator Lights
MIX LOW ‐When the MIX LOW symbol is
illuminated, the mix hopper has a low supply of mix
and should be refilled as soon as possible.
MIX OUT ‐When the MIX OUT symbol is
illuminated, the mix hopper has been almost
completely exhausted and has an insufficient supply
of mix to operate the freezer. At this time, the AUTO
mode is locked out and the freezer will be placed in
the STANDBY mode. To initiate the refrigeration
system, add mix to the mix hopper and touch the
AUTO symbol . The freezer will automatically
begin operation.
Adjustable Draw Handle
This equipment features an adjustable draw
handle(s) to provide the best portion control, giving a
better, consistent quality to your product and
controlling food costs. The draw handle should be
adjusted to provide a flow rate of 5 to 7‐1/2 oz (142
to 213 g) of product by weight per 10 seconds. To
INCREASE the flow rate, turn the screw
CLOCKWISE, and COUNTERCLOCKWISE to
DECREASE the flow rate. (See Figure 1.)

Beater Motor Overload
The beater motor overloads are located in the rear
panel.
The beater motor overload protects the beater motor
from an overload condition. Should an overload
occur, the reset mechanism will trip. To properly
reset the freezer, place the power switch in the OFF
position. Press the reset button firmly. Turn the
power switch to the ON position. Touch the WASH
symbol and observe the freezer's performance.
WARNING: Do not use metal objects to
press the reset button. Failure to comply may result
in severe personal injury or death from electrical
shock.
If the beater motor is turning properly, touch the
WASH symbol to cancel the cycle. Touch the AUTO
symbol to resume normal operation. If the freezer
shuts down again, contact your authorized service
technician.
Air/Mix Pump Reset Mechanism
(C712 Only)
The reset buttons for the pumps are located in the
rear panel.
The reset protects the pump from an overload
condition. Should an overload occur, the reset
mechanism will trip. To reset the pump, press the
reset button firmly.
WARNING: Do not use metal objects to
press the reset button. Failure to comply may result
in severe personal injury or death.
Condenser Fan Motor
The condenser fan motor is driven by the software.
The L1 to the fan is connected to the interface board
at J6-6. The condenser fan is programmed to run
any time the compressor is on and to stay running
for 30 seconds after the compressor cycles off.

Universal Control Programming
Operating Screen
Descriptions
______________________________
The fluorescent display located in the center of the
control panel is normally blank during the daily
operation of the unit. The display is activated when
the SEL key or the Manager's Menu is selected. The
display screen will also alert the user of specific
faults detected by the control.
Power Up Memory (Initializing)
The seven segment display should display “00”
during the initializing sequence.
When the unit is powered, the control system will
initialize to perform a system check. The screen will
display “INITIALIZING”. There will be three types of
data the system will check: LANGUAGE, SYSTEM
DATA, and CONFIG DATA.
Language Initialization
The UVC platform supports multiple languages by
keeping specific strings in battery backed RAM.
After power-up or a CPU reset, the strings are
tested to see if the language strings are present and
not corrupted. If the strings are present and not
corrupted, initialization continues. Otherwise, the
operator is prompted to select a language. While
language strings are being checked for integrity, the
following screen is displayed.
Initializing
Language
Note: If there is a language initialization fault, the
unit will force a language selection prior to the
initializing sequence. The standard menu LED's
should light, as if it were in a menu. If a language
has been selected, the unit is powered down. The
unit should not ask for a language unless there is
another language initialization fault. English is the
factory default setting.
System Data
System data is protected separately from the rest of
the data in memory. System data includes variables
that change frequently, such as the mode the unit is
in, lockout status, serving counters, fault codes, and
others. While System Data is being checked the
following screen is displayed.
Initializing
System Data
If the System Data is corrupted, the unit is set to
OFF, the serving counters are set to zero, and the
faults are cleared. A “SYSTEM CRC ERR” fault is
set and displayed on the VFD. An acknowledgement
(SEL key) is required.
Configuration Data
Configuration data is separate from the rest of the
data in the memory. Configuration data is
information entered through operator and service
menus. While the Configuration Data is being
checked, the following screen is displayed.
Initializing
Config Data
If the Configuration Data is corrupted, all user and
service settings are set to defaults. A “CONFIG
CRC ERR” fault is set and displayed on the VFD.
The system will continue to operate in its previous
mode, but according to default settings.
After the memory integrity has been tested, the
Safety Timeout screen will be displayed.
