DO NOT install these machines in an area where a water jet could be used. Failure to follow this instruction may result in serious electrical shock.
Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided with a hand shut-off valve. On the underside of the base pan or on the right side, two 3/8” I.P.S. water connections for inlet and outlet are provided for easy hook-up. 1/2” inside diameter water lines should be connected to the machine. (Flexible lines are recommended, if local codes permit.) 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.
Air Cooled Units
Model C708: Requires a minimum of 6” (152 mm) of clearance on both sides and 0” in the rear of the unit.
Model C716: Requires a minimum of 3” (76 mm) of clearance on all sides.
This will allow for adequate air flow across the condensers. Failure to allow adequate clearance can reduce the refrigeration capacity of the freezers and possibly cause permanent damage to the compressors.
Electrical Connections
Each freezer requires one power supply for each data label. Check the data label on the freezer for fuse, circuit ampacity and electrical specifications. Refer to the wiring diagram provided inside of the electrical box, for proper power connections.
In the United States, this equipment is intended to be installed in accordance with the National Electrical Code (NEC), ANSI/NFPA 70-1987. The purpose of the NEC code is the practical safeguarding of persons and property from hazards arising from the use of electricity. This code contains provisions considered necessary for safety. Compliance therewith and proper maintenance will result in an installation essentially free from hazard!
In all other areas of the world, equipment should be installed in accordance with the existing local codes. Please contact your local authorities.
Stationary appliances which are not equipped with a power cord and a plug or other device to disconnect the appliance from the power source must have an all-pole disconnecting device with a contact gap of at least 3 mm installed in the external installation.
CAUTION: This equipment must be properly grounded! Failure to do so can result in severe personal injury from electrical shock!
Beater rotation must be clockwise as viewed looking into the freezing cylinder.
Note: The following procedures should be

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 3 |
Safety |
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.
To Operate Safely:
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.
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.
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 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.
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.
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.

Operating Screen Descriptions
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.
Note: The displays illustrated in this section are those seen on the Models C708/C709. The Model C716/C717 versions may vary slightly.
Power Up Memory (Initializing)
The seven segment display should display “00” during the initializing sequence.
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.
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 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
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.
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.
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.
Initializing
Config Data
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.
Lockout Data
Lockout data is protected separately from the rest of the data in the memory. While the Lockout Data is being checked, the following screen is displayed.
Initializing
Lockout Data
If Lockout Data is corrupted, all lockout history data is cleared. A “LOCKOUT CRC ERR” fault 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.
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.)
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.

Heat Cycle
The HEAT symbol on the control panel is illuminated throughout the heat treatment cycle. Two warning messages will be displayed on the screen. “DO NOT DRAW” will be displayed when the mix temperature is below 130°F (54.4°C).
DO NOT DRAW
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.
HOT PRODUCT
DO NOT attempt to draw product or disassemble the unit during the HEAT cycle. The 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.

If the Heat Treatment Cycle fails, the screen will display a failure message and return the freezer to the STANDBY mode.
Always comply with local guidelines for the maximum number of days allowed between brush clean cycles. (See the Manager’s Menu for setting the Brush Clean interval.)
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 Cylinder or Hopper) occurred during a Heat cycle.
1.The following screen will be displayed if a Brush Clean Cycle Time has occurred.

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 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.
The FREEZER LOCKED message will remain on the display until the brush clean requirements are fulfilled. The freezer must be disassembled in order 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 lock is indicated on the second line.
NO HEAT CYCLE START
REASON
>HEAT CYCLE BRUSH CLEAN
If the reason for the soft lock has been corrected, selecting HEAT CYCLE initiates a Heat Cycle immediately. Selecting BRUSH CLEAN when the previous message is displayed will hard lock the machine and brush cleaning will be necessary.

>HEAT CYCLE BRUSH CLEAN
When one of these messages appears, automatic freezer operation cannot take place until the freezer is disassembled and brush cleaned, or has completed a heat treatment cycle.
Once the freezer is unlocked by starting a heat treatment cycle the HEAT symbol will illuminate and the following message will be displayed on the screen.
DO NOT DRAW
If BRUSH CLEAN is selected to clear the lockout by brush cleaning the machine, the FREEZER LOCKED message will remain on the display until the brush clean requirements are fulfilled. The freezer must be disassembled in order to activate the five minute timer on the display screen. Once the timer counts down to zero, the lockout is cleared.
