Section 2To the Operator
Your freezers have been carefully engineered and
manufactured to give you dependable operation.
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.
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.
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 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.
Compressor Warranty Disclaimer
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.
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.
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.

Section 3Safety
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.
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.
SDO NOT allow untrained personnel to
operate this machine.
SDO NOT operate the freezer unless all
service panels and access doors are
restrained with screws.
SDO NOT remove the door, beater and
blades, or drive shaft unless the control
switch is in the OFF position.
SDO 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.

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.
SDO NOT operate the freezer unless it is
properly grounded.
SDO NOT operate the freezer with larger
fuses than specified on the freezer data
label.
SDO 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.
DO NOT use a water jet to clean or rinse the
freezer. Failure to follow this instruction may result in
serious electrical shock.
The freezer must be placed on a level
surface. Failure to comply may result in personal
injury or equipment damage.
USE EXTREME CAUTION when removing

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.
NOISE LEVEL: Airborne noise emission does not
exceed 78 dB(A) when measured at a distance of
1.0 meter from the surface of the machine and at a
height of 1.6 meters from the floor.
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.
The following chart identifies the symbol definitions.

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.

product is hot and under extreme pressure.
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.
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.
When the entire heat cycle has been completed, the
HEAT symbol will no longer be illuminated. The
machine will enter the STANDBY mode (STANDBY
symbol illuminates). The machine can be placed in
AUTO or left in STANDBY.
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.

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.
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

to activate the five minute timer on the display
screen. Once the timer counts down to zero, the
lockout is cleared.
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

Section 6Operating 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.
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.

film is removed. Be sure to brush all surfaces and
holes, especially the holes in the pump components
and the draw valve hole in the freezer door.
Rinse all parts with clean, warm water. Place the
parts on a clean, dry surface to air dry overnight.
Step 3
Return to the freezer with a small amount of
cleaning solution. Using the black brush, clean the
rear shell bearing at the back of the freezing
cylinder. (See Figure 60.)

Models C708 & C716Operating Procedures
Section 7Important: Operator Checklist
During Cleaning and Sanitizing
ALWAYS FOLLOW LOCAL HEALTH CODES.
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.
CLEANING AND SANITIZING MUST BE
PERFORMED EVERY TWO WEEKS.
Troubleshooting Bacterial Count
j 1. Thoroughly clean and sanitize the machine
regularly, including complete disassembly and
brush cleaning.
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.
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 6. The temperature of the mix in the mix hopper
and walk-in cooler should be below 40_F
(4.4_C).
j 7. Discard remaining mix from the freezer during
“Cleaning Procedures”.
Regular Maintenance Checks
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.
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 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.
j 4. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
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.
Caution: Always disconnect
electrical power prior to cleaning the
condenser. Failure to follow this instruction
may result in electrocution.
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.

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