|
|
Section 1 |
To the Installer |
The Model C300NP 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.
Air Cooled Units
Air cooled units require a minimum of 3” (76 mm) of air space on the rear and left side to the top of the unit, 0” on the right side, and 12” (305 mm) to the ceiling. This is required to allow for adequate air flow through the condenser(s). Failure to allow adequate clearance can reduce the refrigeration capacity of the freezer and possibly cause permanent damage to the compressor(s).
Water Cooled Refrigeration Units
(Water Cooled Units Only)
On the back of the unit, two additional 3/8” (9.5 mm) F.P.T. water connections for condenser inlet and outlet have been provided for easy hook-up. 3/8” (9.5 mm) inside diameter water lines should be connected to the machine. Flexible lines are recommended if local codes permit. Failure to use adequate size water lines may cause the unit to go on high head pressure and shut down.
Depending on local water conditions, it may be advisable to install a water strainer to prevent foreign substances from clogging the automatic water valve.
DO NOT INSTALL A HAND SHUT-OFF VALVE ON THE “OUT” LINE! Water cooled units are counter flow and the water should flow in this order: First through the automatic water valve. Second, through the inlet located at the bottom of the condenser. Third, through the outlet fitting located at the top of the condenser to an open trap drain.
IMPORTANT: Water pressures are pre-set at the factory. Do not adjust the water pressure.
Improper water adjustments may cause operation discrepancies.
Water Connections
An adequate cold water supply must be provided with a hand shut-off valve. On the back of the unit, a 3/8” (9.5 mm) male flare water connection has been provided for easy hook-up. A flexible line is recommended, if local codes permit. A minimum of 25 psi water pressure is required to avoid having the unit cut out the low water pressure switch. A booster pump must be provided if this pressure is not available. It is always a good practice to have a filter system to improve the quality of the water and to avoid clogging the operating components.
Note: Water lines beyond 200 ft. (61 m) require 1/2” (13 mm) water lines.
INSTALL POTABLE WATER CONNECTION WITH ADEQUATE BACK-FLOW PROTECTION TO COMPLY WITH APPLICABLE NATIONAL, STATE AND LOCAL CODES.
It is always a good practice to have a filter system to improve the quality of the water and to avoid clogging the operating components.
IMPORTANT: The water filter (064422-SER) must be thoroughly flushed with water before connecting it to the machine. This removes any loose particles present from the manufacture of the filter that could clog the flow control. To flush the filter, connect the inlet end of the filter to the water supply. Position the outlet end of the filter over an empty pail. Open the water supply. Allow water to flow through the filter until the water exiting the filter is clear. Close the water supply. Attach the outlet end of the filter to the machine. Reopen the water supply.

Electrical Connections
Each unit requires one power supply for each data label on the unit. Check the data label(s) on the freezer for branch circuit overcurrent protection or fuse, circuit ampacity, and other electrical specifications. Refer to the wiring diagram provided inside of the control 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.
Figure 2
The following procedures should be performed by a trained service technician:
To correct rotation on a single-phase unit, change the leads inside the beater motor. Follow the diagram printed on the motor. (Note: Three-phase units have single-phase motors.)

Section 2 |
To the Operator |
|
|
The freezer you have purchased has been carefully engineered and manufactured to give you dependable operation.
The Model C300NP, when properly operated and cared for, will produce a consistent quality product. Like all mechanical products, this machine will require cleaning and scheduled 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 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 study these procedures together in order to be properly trained and to make sure that no misunderstandings exist.
In the event you should require technical assistance, please contact your local authorized Taylor Distributor.
Warranty is valid only if the parts are authorized Taylor parts, purchased from an authorized Taylor Distributor, and the required service work is provided by an authorized Taylor service technician. Taylor reserves the right to deny warranty claims on equipment or parts if non-approved parts or refrigerant were installed in the machine, system modifications were performed beyond factory recommendations, or it is determined that the failure was caused by neglect or abuse.
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.
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 warranty, call the local Taylor Distributor or the Taylor Factory. Be prepared to provide the Model/Serial Number of the unit in question.

Control Switch
The control switch is located at the top left corner of the control channel. When placed in the ON position, allows SLUSHTECH operation.
Liquid Crystal Display
The Liquid Crystal Display (LCD) is located on the front control panel. The LCD is used to show the current operating mode of the freezing cylinders. The LCD also indicates whether there is enough syrup, CO2, and water being supplied to the freezer. If an error in the machine operation occurs, a warning tone will sound and the word “FAULT” will flash on the third line of the display.
Operational Mode Display
The displays below illustrate the Operational Mode Displays. This information appears on the LCD during normal operation.
When the unit is plugged into the wall receptacle and the control switch is in the ON position, this screen appears.
SAFETY TIMEOUT
ANY KEY ABORT
This display will remain on the LCD for 60 seconds unless a key is pressed. If any key is pressed (or 60 seconds passes) then the next screen appears.

Line 1 indicates the operating mode for each freezing cylinder.
Line 2 indicates the status of the syrup systems in each freezing cylinder. As long as syrup is available, the word “OK” will appear on the LCD. When the syrup supply is insufficient, the word “OUT” will flash on the LCD. The same rules apply to the fourth line which indicates the status of the CO2 and the H2O.
The third line of this display is a fault indicator. If an error in machine operation occurs, the word “FAULT” will be displayed on the LCD.

Operator Menu Timeout
If the display is left in the operator menu or any of the operator menu selections, except for Current Conditions, the display will return to the system mode screen 60 seconds after the last keypress. The Current Conditions screen will be displayed until manually changed.
Finding Current Fault Conditions
Screen B is FAULT DESCRIPTION. The fault description will indicate if there is a fault in one of the freezing cylinders. When the actual fault is corrected, the warning tone will stop. Only item 9 requires pressing the OFF (<- -) key to clear the fault message and the warning tone.
