Section 1 |
To the Installer |
This machine is designed for indoor use only.
DO NOT install the machine 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 rear of the base pan, two 3/8” I.P.S. (for single-head units) or two 1/2” I.P.S. (for double-head units) water connections for inlet and outlet have been 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.
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.

Section 2 |
To the Operator |
|
|
The freezer you have purchased has been carefully engineered and manufactured to give you dependable operation. The Taylor Models PH71/PH84, freezers, when properly operated and cared for, will produce a consistent quality product. Like all mechanical products, this machine 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 and correct for 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 all personnel responsible for the equipment’s operation review these procedures in order to be properly trained and to make sure that there is no confusion.
In the event that 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 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 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 or death. Failure to comply with these warnings may damage the machine and its components. Component damage will result in part replacement expense and service repair expense.

Symbol Definitions
To better communicate in the International arena, the words on many of our operator switches and buttons have symbols to indicate their functions. Your Taylor equipment is designed with these International symbols.
The following chart identifies the symbol definitions used on the operator switches.
= AUTO
= ON
= OFF
= WASH
= PUMP
= MENU
= MIX LOW
= MIX OUT
= HEAT MODE
= CLEAN MANUALLY/BRUSH CLEAN
= POWER
Power Switch
When placed in the ON position, the power switch allows softech control panel operation.
Liquid Crystal Display
The Liquid Crystal Display (LCD) is located on the front control panel. The LCD is used to show the current mode of operation, and whether or not there is sufficient mix.
Indicator Lights
MIX LOW - When the MIX LOW light begins to flash, it indicates the mix hopper has a low supply of mix and should be refilled as soon as possible. On double head units, the word “LOW” will also display on the LCD indicator next to the word “MIX”.
MIX OUT - When the MIX OUT light begins to flash, it indicates 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 press the AUTO key. The freezer will automatically begin operation.
HEAT MODE - When the HEAT MODE light is flashing, it indicates that the freezer is in the process of a heat cycle.
CLEAN MANUALLY - When the CLEAN MANUALLY light is flashing, it indicates that the machine must be disassembled and brush cleaned within 24 hours.
When the MIX LOW, MIX OUT, HEAT MODE, and CLEAN MANUALLY indicator lights are all flashing, this signifies a locked condition.
Reset Mechanism
The reset button is located in the service panel. The Model PH84 has two reset mechanisms, one for each side of the freezer.
The reset mechanism 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. Clear the fault. Press the WASH key and observe the freezer’s performance. Open the side access panel to check if the beater motor is turning the drive shaft in a clockwise (from operator end) direction without binding.
Warning: Do not use metal objects to press the reset button. Failure to comply may result in severe personal injury or death.
If it is turning properly, press the WASH key to cancel cycle. Press the AUTO key on both sides of the machine to resume normal operation. If the freezer shuts down again, contact your authorized service technician.

Air/Mix Pump Reset Mechanism
The reset button for the pump is located in the service 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. The Model PH84 has two pump reset mechanisms, one for each side of the freezer.
Warning: Do not use metal objects to press the reset button. Failure to comply may result in severe personal injury or death.
Adjustable Draw Handle
This unit features an adjustable draw handle to provide the best portion control, giving a better, consistent quality to your product and controlling costs. The draw handle should be adjusted to provide a flow rate of 5 to 7-1/2 oz. of product by weight per 10 seconds. To INCREASE the flow rate, turn the screw COUNTERCLOCKWISE, and CLOCKWISE to DECREASE the flow rate. In addition, for purposes of SANITIZING and RINSING, the flow rate can be increased by removing the pivot pin and placing the restrictive bar on the TOP. When drawing product, always have the restrictive bar on the BOTTOM.
IMPORTANT: Once the draw rate is set, tighten the lock nut with a wrench.
Operating Screen Descriptions
When the machine is powered the system will initialize. The screen will display “INITIALIZING”. There will be four types of data the system will check: LANGUAGE, SYSTEM DATA, CONFIG DATA, and LOCKOUT DATA. During the INITIALIZING... LANGUAGE screen, the alarm will be on. If the system data, configuration data, or lockout history data has become corrupt, the following screen will alert the operator that the system settings may have been changed.

Once the system has initialized the SAFETY TIMEOUT screen is displayed and the alarm is turned on.
SAFETY TIMEOUT
ANY KEY ABORTS
This screen will be displayed, with the alarm on, for 60 seconds or until any key is pressed.
After the safety timeout has been completed, and the power switch is OFF, one of the following screens is displayed.
The first screen is displayed if the machine is not in a brush clean state. If any of the requirements for a brush clean have not been met, the time displayed will remain at 5:00 minutes.

The mix temperature must be raised above 151_F (66.1_C) within 90 minutes or the freezer will be locked in STANDBY, and the cycle failure display will appear.
In the example, the hopper temperature is 140_F (60_C). The phase shows that the machine is in the heat phase of the heat treatment cycle.
When the heating phase is complete, the freezer goes into the holding phase of the cycle. The holding phase will hold the temperature above 151_F (66.1_C) for a minimum of 30 minutes.
In this example, the hopper temperature is 151_F (66.1_C).
