Models 8751/8754 Table of Contents Section 1 To the Installer Electrical Connections This machine is designed for indoor use only. Each freezer requires one power supply for each data label. Check the data label(s) 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. DO NOT install the machine in an area where a water jet could be used to clean or rinse the machine. Failure to follow this instruction may result in serious electrical shock. 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! 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 for both single-head and double-head units. 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 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 of any model freezer. Note: The following procedures should be performed by a trained service technician. Air Cooled Units To correct rotation on a three-phase unit, interchange any two incoming power supply lines at freezer main terminal block only. Air cooled units require a minimum of 3” (76 mm) of clearance around all sides of the freezer to allow for adequate air flow across the condenser(s). Failure to allow adequate clearance can reduce the refrigeration capacity of the freezer and possibly cause permanent damage to the compressor. To correct rotation on a single-phase unit, change the leads inside the beater motor. (Follow diagram printed on motor.) Electrical connections are made directly to the terminal block provided in the main control box located behind the service panel. 050415 Models 8751/8754 1 To the Installer Section 2 To the Operator The freezer you have purchased has been carefully engineered and manufactured to give you dependable operation. The Taylor Company soft-serve models covered in this manual consist of the 8751 and 8754. 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 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. 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. 050818 To the Operator 2 Models 8751/8754 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.

Your Taylor equipment is designed with these International symbols. When the MIX REF key is pressed, the light comes on indicating the mix hopper refrigeration system is operating. For the Model 8754 the MIX REF is controlled by the left side of the freezer as viewed from the operator end. The MIX REF function cannot be cancelled unless the AUTO or STANDBY modes are cancelled first. The following chart identifies the symbol definitions. = OFF STANDBY Key = ON = MIX The Separate Hopper Refrigeration System (SHR) and the Cylinder Temperature Retention System (CTR) are standard features. The SHR incorporates the use of a separate small refrigeration system to maintain the mix in the hopper below 40_(4.4_C) to assure bacteria control. The CTR works with the SHR to maintain a good quality product. During long “No Sale” periods, it is necessary to warm the product in the freezing cylinder to approximately 35_F to 40_F (1.7_C to 4.4_C) to prevent overbeating and product breakdown. = STANDBY = WASH = AUTO = PUMP Power Switch To activate the SHR and CTR, press the STANDBY key. Remove the air orifice and place the air tube (end without the hole) into the mix inlet hole. When placed in the ON position, the power switch allows SOFTECH control panel operation. When the STANDBY key is pressed, the light comes on, indicating the CTR (Cylinder Temperature Retention System) has been activated. In the STANDBY mode, the WASH and AUTO functions are automatically cancelled. The MIX REF function is automatically locked in to maintain the mix in the hopper. Indicator Lights Located on the front of the machine is a mix level indicating light. When the light begins to flash, it indicates that the mix hopper has a low supply of mix and should be refilled as soon as possible. Always maintain at least 3” (76 mm) of mix in the hopper. If you neglect to add mix, a freeze-up may occur. This will cause eventual damage to the beater, blades, drive shaft, and freezer door. Models 8751/8754 To resume normal operation, press the AUTO key. When the unit cycles off, the product in the freezing cylinder will be at serving viscosity. At this time, place the air tube (end with the hole) into the mix inlet hole and install the air orifice. 11 Important: To the Operator WASH Key If the beater motor is turning properly, press the WASH key to cancel the cycle. Press the AUTO key to resume normal operation. If the freezer shuts down again, contact a service technician. (For the Model 8754 press the AUTO key on both sides of the unit to resume normal operation.) When the WASH key is pressed, the light comes on. This indicates beater motor operation. The STANDBY or AUTO modes must be cancelled first to activate the WASH mode. AUTO Key Air/Mix Pump Reset Mechanism When the AUTO key is pressed, the light comes on. This indicates that the main refrigeration system has been activated. In the AUTO mode, the WASH or STANDBY functions are automatically cancelled. The MIX REF function is automatically locked in to maintain the mix in the mix hopper. 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. Note: An indicating light and an audible tone will sound whenever a mode of operation has been pressed. To cancel any function, press the key again. The light and mode of operation will shut off. Adjustable Draw Handle These units feature an adjustable draw handle to provide the best portion control. The draw handle should be adjusted to provide a flow rate of 5 to 7-1/2 oz. (148 to 222 ml) of product per 10 seconds. To INCREASE the flow rate, turn the screw COUNTERCLOCKWISE. Turn the screw CLOCKWISE to DECREASE the flow rate. During “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 place the restrictive bar on the bottom. Pump Key When the PUMP key is pressed, the light comes on, indicating the air/mix pump will operate as required. Reset Button The reset button is located in the service panel on the front of the machine. The reset protects the beater motor from an overload condition. If an overload occurs, the reset mechanism will trip. To properly reset the freezer, press the AUTO key to cancel the cycle. Turn the power switch to the OFF position. Press the reset button firmly. Do not use metal objects to press the reset button. Failure to follow this instruction may result in electrocution. Turn the power switch to the ON position. Press the WASH key and observe the freezer’s performance. Open the side access panel. Make sure the beater motor is turning the drive shaft in a clockwise direction (from the operator end) without binding. Important: To the Operator Figure 1 IMPORTANT: Once the draw rate is set, tighten the lock nut with a wrench. 12 Models 8751/8754 Feed Tube (Back--up Option) If the air/mix pump has become inoperable because of a missing or damaged part, the operator can temporarily operate the unit using the feed tube. The product ejection rate will be slower when the feed tube is used instead of the air/mix pump. The feed tube serves two purposes. One end of the tube has a hole and the other end does not. 1. Normal Operation During normal operation, the end of the feed tube with the hole is placed into the mix inlet hole. Every time the draw handle is raised, new mix and air from the hopper flow into the freezing cylinder. This keeps the freezing cylinder properly loaded and maintains overrun. 2. Long “No Sale” Periods During long “No Sale” periods, the unit can be placed into the Standby mode. This maintains product temperatures below 40_F (4.4_C) in both the hopper and the freezing cylinder, and helps prevent overbeating and product breakdown. To place the unit into the Standby mode, press the STANDBY key. Remove the air orifice. Lubricate the o--rings located on the end of the feed tube without the hole. Place that end of the tube into the mix inlet hole.This will prevent any mix from entering the freezing cylinder.

These models, for all practical purposes of operation, are the same. Fill the inside portion of the seal with 1/4” more lubricant and lubricate the flat side of the seal that fits onto the rear shell bearing. Each unit stores mix in a hopper. The mix is pumped into the freezing cylinder. They have 3.4 quart (3.2 liter) capacity freezing cylinders and 20 quart (18.9 liter) mix hoppers. Duplicate the following procedures, where they apply, for the second freezing cylinder on the Model 8754. 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. Figure 3 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 26, “Disassembly”, and start there. Insert the drive shaft into the freezing cylinder, hex end first, and into the rear shell bearing until the seal fits securely over the rear shell bearing. Engage the hex end firmly into the drive coupling. Be sure the drive shaft fits into the drive coupling without binding. Assembly Note: When lubricating parts, use an approved food grade lubricant (example: Taylor Lube). MAKE SURE POWER SWITCH IS IN THE “OFF” POSITION! Failure to follow this instruction may result in severe personal injury from hazardous moving parts. Step 1 Install the drive shaft. Lubricate the groove and shaft portion that comes in contact with the bearing on the beater drive shaft. Slide the seal over the shaft and groove until it snaps into place. DO NOT lubricate the hex end of the drive shaft. Figure 4 050201 Operating Procedures 14 Models 8751/8754 Repeat steps 1 and 2 for the other side of the freezer on the Model 8754.

Properly prepare the cleaning and sanitizing solutions. Read and follow 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. 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. WE RECOMMEND SANITIZING. DAILY CLEANING j 8. The temperature of the mix in the mix hopper and walk-in cooler should be below 40_F. (4.4_C.). AND Regular Maintenance Checks ALWAYS FOLLOW LOCAL HEALTH CODES. 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. Troubleshooting Bacterial Count 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 machine regularly, including complete disassembly and brush cleaning. 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 2. Use all brushes supplied for thorough cleaning. The brushes are specially designed to reach all mix passageways. j 4. Dispose of o-rings and seals if they are worn, torn, or fit too loosely, and replace with new ones. 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 5. Follow all lubricating procedures as outlined in “Assembly”. j 4. Use the black bristle brush to thoroughly clean the rear shell bearing located at the rear of the freezing cylinder. Be sure to have a generous amount of cleaning solution on the brush. 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 5. IF LOCAL HEALTH CODES PERMIT THE USE OF RERUN, make sure the mix rerun is stored in a sanitized, covered stainless steel container and used the following day. DO NOT prime the machine with rerun. When using rerun, skim off the foam and discard. Mix the rerun with fresh mix in a ratio of 50/50 during the days operation. j 6. On a designated day of the week, run the mix as low as feasible and discard it after closing. This will break the rerun cycle and reduce the possibility of high bacteria and coliform counts. Caution: Always disconnect electrical power prior to cleaning the condenser. Failure to follow this instruction may result in electrocution. 051215 Models 8751/8754 27 Important: Operator Checklist Winter Storage j 7. If your machine is equipped with an auxiliary refrigeration system, check the auxiliary condenser for accumulation of dirt and lint. Dirty condensers will reduce the refrigeration capacity of the mix hopper. Condensers must be cleaned monthly with a soft brush. Never use screwdrivers or other metal probes to clean between the fins. 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. Caution: Always disconnect electrical power prior to cleaning the condenser. Failure to follow this instruction may result in electrocution. Disconnect the freezer from the main power source to prevent possible electrical damage. j 8. 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. 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. The Air/Mix Pump Checklist j 1. Dispose of o-rings and check bands if they are worn, torn or fit too loosely. Replace them with new ones. Your local Taylor Distributor can perform this winter storage service for you. j 2. Follow lubricating procedures carefully. Do not lubricate check bands. 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. j 3. Handle plastic pump parts with care to avoid nicks and cracks. j 4. Be sure the air/mix pump is properly attached to the drive hub, or severe and costly damage may occur.
