Section 2
Your freezers have been carefully engineered and
manufactured to give you dependable operation.

Compressor Warranty Disclaimer

These units, when properly operated and cared for,
will produce a consistent quality product. Like all
mechanical products, they will require cleaning and
maintenance. A minimum amount of care and
attention is necessary if the operating procedures
outlined in this manual are followed closely.

The refrigeration compressors 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
owner’s responsibility to make this fact known to any
technician he employs.

This Operator’s Manual should be read before
operating or performing any maintenance on your
equipment.
Your Taylor freezer will NOT eventually compensate
for and correct any errors during the set-up or filling
operations. Thus, the initial assembly and priming
procedures are of extreme importance. It is strongly
recommended that personnel responsible for the
equipment’s operation, both assembly and
disassembly, go through these procedures together
in order to be properly trained and to make sure that
no confusion exists.

It should also 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.

In the event you should require technical assistance,
please contact your local authorized Taylor
Distributor.

If the crossed out wheeled bin symbol is
affixed to this product, it signifies that this product is
compliant with the EU Directive as well as other
similar legislation in effect after August 13, 2005.
Therefore, it must be collected separately after its
use is completed, and cannot be disposed as
unsorted municipal waste.

The Taylor Company 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 warranty, call the local Taylor Distributor
or the Taylor Factory. Be prepared to provide the
Model/Serial Number of the unit in question.

The user is responsible for returning the product to
the appropriate collection facility, as specified by
your local code.
For additional information regarding applicable local
laws, please contact the municipal facility and/or
local distributor.

Safety

Section 3
We at Taylor Company are concerned about the
safety of the operator when he or she comes in
contact with the freezer and its parts. Taylor has
gone to extreme efforts to design and manufacture
built-in safety features to protect both you and the
service technician. As an example, warning labels
have been attached to the freezer to further point
out safety precautions to the operator.

DO NOT allow untrained personnel to
operate this machine.
S DO NOT operate the freezer unless all
service panels and access doors are
restrained with screws.
S DO NOT remove the door, beater and
blades, or drive shaft unless the control
switch is in the OFF position.
S DO NOT put objects or fingers in door
spout.
Failure to follow these instructions may result in
contaminated product or personal injury from
hazardous moving parts.

IMPORTANT - Failure to adhere to the
following safety precautions may result in
severe personal injury. Failure to comply with
these warnings may also damage the machine and
its components. Component damage will result in
part replacement expense and service repair
expense.

To Operate Safely:

The freezer must be placed on a level
surface. Failure to comply may result in personal
injury or equipment damage.

DO NOT operate the freezer without reading
this operator’s manual. Failure to follow this
instruction may result in equipment damage, poor
freezer performance, health hazards, or personal
injury.

USE EXTREME CAUTION when removing
the beater assembly. The scraper blades are very
sharp and may cause injury.
DO NOT obstruct air intake and discharge openings:
C708: A minimum of 6” (152 mm) air space is
required on both sides and 0” on the rear.

DO NOT operate the freezer unless it is
properly grounded.
S DO NOT operate the freezer with larger
fuses than specified on the freezer data
label.
S DO NOT attempt any repairs unless the
main power supply to the freezer has been
disconnected.
Failure to follow these instructions may result in
electrocution or damage to the machine. Consult
your electrician.

C716: A minimum of 3” (76 mm) air space is
required on all sides.
Failure to follow these instructions may cause poor
freezer performance and damage to the machines.
These freezers are designed to operate indoors,
under normal ambient temperatures of 70°-75°F
(21°-24°C). The freezers have successfully
performed in high ambient temperatures of 104°F
(40°C) at reduced capacities.

Symbol Definitions

When placed in the ON position, the power switch
allows control panel operation.

To better communicate in the International arena,
symbols have replaced words on many of our
operator switches, function, and fault indicators.
Your Taylor equipment is designed with these
International symbols.

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 the hopper.

The following chart identifies the symbol definitions.

Important: To the Operator

If the beater motor is turning properly, touch the
WASH symbol

Operating Screen Descriptions

to cancel the cycle. Touch the

AUTO symbol
to resume normal operation. If the
freezer shuts down again, contact your authorized
service technician.

The fluorescent display located in the center of the
control panel is normally blank during the daily
operation of the machine. The display is activated
when the SEL symbol or the Manager’s Menu is
selected. The display screen will also alert the
operator of specific faults detected by the control.

Air/Mix Pump Reset Mechanism

Note: The displays illustrated in this section are
those seen on the Models C708/C709. The Model
C716/C717 versions may vary slightly.

This reset button 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.

Power Up Memory (Initializing)
The seven segment display should display “00”
during the initializing sequence.

WARNING: Do not use metal objects to
press the reset button. Failure to comply may
result in severe personal injury or death.

When the machine is powered, the control system
will initialize to perform a system check. The screen
will display “INITIALIZING”. There will be four types
of data the system will check: LANGUAGE,
SYSTEM DATA, CONFIG DATA, and LOCKOUT
DATA.

Adjustable Draw Handle
These units feature an adjustable draw handle(s) to
provide the best portion control, giving a better,
consistent quality to your product and controlling
costs. The draw handle(s) 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. To
DECREASE the flow rate, turn the screw
COUNTERCLOCKWISE . (See Figure 10.)

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.

10354

Initializing
Language

Note: If there is a language initialization fault, the
machine 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
machine should not ask for a language unless there
is another language initialization fault. English is the
factory default setting.

System Data

If Lockout Data is corrupted, all lockout history data
is cleared. A “LOCKOUT CRC ERR” fault is
displayed.

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
machine is in, lockout status, serving counters, fault
codes, and others. While System Data is being
checked the following screen is displayed.

After the memory integrity has been tested, the
Safety Timeout screen will be displayed.
Heat Cycle Data
Heat cycle data is checked separately from the rest
of the data in memory. Each individual Heat Cycle
Data record is monitored for corruption individually.
At the start of a heat cycle, the next Heat Cycle data
record is cleared and data for the heat cycle is
written to it. The current Heat Cycle Data is
displayed as the first heat cycle record in the HEAT
CYCLE DATA menu option.

Initializing
System Data

If the System Data is corrupted, the machine 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.

The heat cycle data records are checked for integrity
when the record is accessed, presently only through
the HEAT CYCLE DATA menu option. (For
additional Heat Cycle Data information,
see page 24.)

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 Configuration Data is being checked
the following screen is displayed.

Once the system has initialized, the number of days
until brush cleaning is required is indicated on the
control panel. The SAFETY TIMEOUT screen will
be displayed with the alarm on for 60 seconds or
until any control symbol is touched.

Initializing
Config Data
SAFETY TIMEOUT
ANY KEY ABORTS

If 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.

Power Switch OFF
Lockout Data
After the safety timeout has been completed and the
power switch is OFF, the following screen is
displayed.

Lockout data is protected separately from the rest of
the data in the memory. While the Lockout Data is

DO NOT DRAW
UNIT CLEANED

When the temperature of the mix is above 130°F
(54.4°C) the screen will display a message
indicating that HOT PRODUCT is in the machine.

International Models Only:
HOT PRODUCT

Some International models will continuously display
the temperature of the mix hopper when the power
switch is in the ON position.

UNIT CLEANED

In the HEAT cycle, the mix temperature in the
hopper and freezing cylinder must be raised to
151°F (66.1°C) within 90 minutes.
When the heating phase is complete, the freezer
goes into the holding phase of the cycle. The holding
phase will keep the temperature above 151°F
(66.1°C) for a minimum of 35 minutes.

If the control is set for international configuration, the
following screen will appear when the heat symbol is
touched.

The final phase of the heat treatment cycle is the
cooling phase. The freezer must cool the mix below
41°F (5°C) within 90 minutes.

immediately start a heat cycle.

To comply with health codes, heat treatment system
freezers must complete a heat treatment cycle
daily, and must be disassembled and brush cleaned
a minimum of every 14 days. Brush cleaning is the
normal disassembly and cleaning procedure found in
the Operator Manual. Failure to follow these
guidelines will cause the control to lock the freezer
out of the AUTO mode.

Note: The machine must be in AUTO or STANDBY
and have sufficient mix in the hopper before the
machine can successfully enter the HEAT mode of
operation.

FREEZER LOCKED

If the machine has hard locked and an attempt is
made to enter AUTO, the machine will enter the
STANDBY mode and display the following message.

Freezer Locks
There are two types of freezer lock conditions that
can occur: Hard Lock or Soft Lock. A Hard Lock
requires the machine be disassembled and brush
cleaned. A Soft Lock can be corrected by either
disassembling and brush cleaning the machine, or
by starting another heat treatment cycle.

FREEZER LOCKED

To restore the message that identified the reason for
the hard lock, turn the power switch OFF for five
seconds and then return the power switch to the ON
position. The original message with the reason for
the Hard Lock will be displayed.

Hardlock
There are two causes of a hard lock failure. The
freezer will hardlock if either the Brush Clean Timer
has elapsed or if a Thermistor Failure (Freezing
Cylinder or Hopper) occurred during a Heat cycle.

Soft Lock
If a heat treatment cycle has not been initiated within
the last 24 hours, a soft lock failure will occur. A soft
lock allows the operator to correct the cause of the
soft lock. The operator has the option of either
starting another heat cycle or brush cleaning the
machine. When a soft lock occurs, the machine will
go into the STANDBY mode. The following message
is displayed on the screen. The reason for the soft
lock is indicated on the second line.

Operating Procedures

The C708 stores mix in a hopper and has a 3.4
quart (3.2 liter) capacity freezing cylinder with a
single spout door. The C716 stores mix in two
hoppers and has two 3.4 quart (3.2 liter) capacity
freezing cylinders with a three spout door.

Step 3
Heavily lubricate the inside portion of the boot seal
and also lubricate the flat end of the boot seal that
comes in contact with the rear shell bearing.
Step 4
Apply an even coat of lubricant to the shaft. DO
NOT lubricate the hex end. (See Figure 13.)

The Model C708 has been selected to illustrate the
step-by-step operating procedures. Duplicate the
procedures, where they apply, for the second
freezing cylinder on the Model C716.

We begin our instructions at the point where we
enter the store in the morning and find the parts
disassembled and laid out to air dry from the
previous night’s cleaning.
These opening procedures will show you how to
assemble these parts into the freezer, sanitize them,
and prime the freezer with fresh mix in preparation
to serve your first portion.
If you are disassembling the machine for the first
time or need information to get to this starting point
in our instructions, turn to page 41, “Disassembly”,
and start there.

Figure 13
Note: To ensure the mix does not leak out of the
back of the freezing cylinder, the middle section of
the boot seal should be convex or extend out from
the seal. If the middle section of the boot seal is
concave or extending into the middle of the seal,
turn the seal inside out.

Freezing Cylinder Assembly

Step 5
Insert the beater drive shaft through the rear shell
bearing in the freezing cylinder and engage the hex
end firmly into the drive coupling. (See Figure 14.)

Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).

MAKE SURE THE POWER SWITCH IS IN
THE “OFF” POSITION! Failure to follow this
instruction may result in severe personal injury from
hazardous moving parts.
Step 1
Before installing the beater drive shaft, lubricate the
groove on the beater drive shaft.
Step 2

Important: Operator Checklist
j 7. Discard remaining mix from the freezer during
“Cleaning Procedures”.

During Cleaning and Sanitizing

ALWAYS FOLLOW LOCAL HEALTH CODES.

Regular Maintenance Checks

Cleaning and sanitizing schedules are governed
by your State or local regulatory agencies and
must be followed accordingly. The following
check points should be stressed during the
cleaning and sanitizing operations.

j 1. Replace scraper blades that are nicked or
damaged. Before installing the beater
assembly, be certain that scraper blades are
properly attached to the helix.

CLEANING AND SANITIZING MUST BE
PERFORMED EVERY TWO WEEKS.

j 3. Using a screwdriver and cloth towel, keep the
rear shell bearing and the female hex drive
socket clean and free of lubricant and mix
deposits.

Troubleshooting Bacterial Count

j 4. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.

j 2. Check the rear shell bearing for signs of wear
(excessive mix leakage in rear drip pan) and
be certain it is properly cleaned.

j 1. Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.

j 5. Follow all lubricating procedures as outlined in
“Assembly”.
j 6. If your machine is air cooled, check the
condensers for accumulation of dirt and lint.
Dirty condensers will reduce the efficiency
and capacity of the machine. Condensers
should be cleaned monthly with a soft brush.
Never use screwdrivers or other metal probes
to clean between the fins.
Note: For machines equipped with an air
filter, it will be necessary to vacuum clean the
filters on a monthly schedule.

j 2. Use all brushes supplied for thorough
cleaning. The brushes are specially designed
to reach all mix passageways.
j 3. Use the white bristle brush to clean the mix
inlet hole which extends from the mix hopper
down to the rear of the freezing cylinder.
j 4. Use the black bristle brush to thoroughly
clean the rear shell bearing located at the rear
of the freezing cylinder and the drive hub
opening in the rear wall of the mix hopper. Be
sure there is a generous amount of cleaning
solution on the brush.

Caution: Always disconnect
electrical power prior to cleaning the
condenser. Failure to follow this instruction
may result in electrocution.

j 5. Properly prepare the cleaning and sanitizing
solutions. Read and follow the label directions
carefully. Too strong of a solution may
damage the parts and too weak of a solution
will not do an adequate job of cleaning or
sanitizing.

j 7. If your machine is water cooled, check the
water lines for kinks or leaks. Kinks can occur
when the machine is moved back and forth for
cleaning or maintenance purposes.
Deteriorated or cracked water lines should be
replaced only by an authorized Taylor
distributor.

j 6. The temperature of the mix in the mix hopper
and walk-in cooler should be below 40_F
(4.4_C).

Important: Operator Checklist

Your local Taylor Distributor can perform this winter
storage service for you.

Winter Storage
If the place of business is to be closed during the
winter months, it is important to protect the freezer
by following certain precautions, particularly if the
building is subject to freezing conditions.

Wrap detachable parts of the freezer such as
beater, blades, drive shaft, and freezer door, and
place them in a protected dry place. Rubber trim
parts and gaskets can be protected by wrapping
them with moisture-proof paper. All parts should be
thoroughly cleaned of dried mix or lubrication which
attract mice and other vermin.

Disconnect the freezer from the main power source
to prevent possible electrical damage.
On water cooled freezers, disconnect the water
supply. Relieve pressure on the spring in the water
valve. Use air pressure on the outlet side to blow out
any water remaining in the condenser, and then add
a liberal amount of permanent type auto anti-freeze.
This is extremely important. Failure to follow this
procedure may cause severe and costly damage to
the refrigeration system.

Important: Operator Checklist

It is recommended that an authorized service
technician perform winter storage draining, to insure
all water has been removed. This will guard against
freezing and rupturing of the components.
