5 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 to clean or rinse the machine. 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 clearance on both sides of the freezer. It is recommended to place the rear of the unit against the wall to prevent the recirculation of warm air. Minimum air clearances must be met to assure adequate air flow for optimum performance. Failure to allow adequate clearance can reduce the refrigeration capacity of the freezer and possibly cause permanent damage to the compressor. Electrical Connections This equipment is supplied with a 3-wire cord and grounding type plug, for connection to a single phase, 60 cycle, branch circuit supply. This unit must be plugged into a properly grounded receptacle. The cord and plug provided are 20 A for 115/60/1, or 15 A for /60/1; therefore, the wall outlet must also be 20 A for 115/60/1 or 15 A for /60/1. Check the data label, located on the side panel for electrical specifications. Note: The following procedures should be performed by a trained service technician. 5. Connect two power supply leads. Attach ground (earth) wire to the grounding lug inside the electrical box. 6. Be sure unit is properly grounded before applying power. In the United States, this equipment is intended to be installed in accordance with the National Electrical Code (NEC), ANSI/NFPA 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 of the freezer. Permanent wiring may be employed, if required by local codes. Instructions for conversion to permanent wiring are as follows: 1. Be sure the freezer is electrically disconnected. 2. Remove the appropriate panel and locate the small electrical box at the base of the freezer. 3. Remove the factory installed cord and strain relief bushing. 4. Route incoming permanent wiring through 7/8 (22 mm) hole in base pan. Figure 1 To correct rotation on a single-phase unit, change the leads inside the beater motor. (Follow the diagram printed on motor.) To the Installer

6 Section 2 To the Operator The freezer you have purchased has been carefully engineered and manufactured to give you dependable operation. The Taylor, 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, sit down together and go through these procedures 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. Note: Constant research results in steady improvements; therefore, information in this manual is subject to change without notice. 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, 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 To the Operator 2

7 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 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. S DO NOT operate the freezer unless it is properly grounded. S DO NOT attempt any repairs unless the main power supply to the freezer has been disconnected. S DO NOT operate the freezer with larger fuses than specified on the freezer data label.

13 Section 6 Operating Procedures The freezer is designed to produce shake or slush product at the desired thickness. This unit has a 7 quart freezing cylinder. 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 brush 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 point in our instructions, turn to page 16, Disassembly, and start there. Note: To ensure that the mix does not leak out of the back of the freezing cylinder, the middle section of the boot seal should be convex or extend out from the seal. If the middle section of the boot seal is concave or extending into the middle of the seal, invert the seal. Assembly Note: When lubricating parts, use an approved food grade lubricant (example: Taylor Lube). Step 1 Slide the o--ring into the groove on the drive shaft. Lubricate the o-ring and shaft portion that comes in contact with the bearing. DO NOT lubricate the square end of the drive shaft. Figure 5 Step 2 Lubricate the boot seal groove and slide the boot seal over the shaft and groove until it snaps into place. Fill the inside portion of the seal with 1/4 more lubricant. Install the drive shaft. Figure 4 Figure 6 9 Operating Procedures

14 Step 3 Insert the drive shaft into the rear shell bearing and engage the square end firmly into the female socket of the drive unit. Be certain that the drive shaft fits into the drive coupling without binding. Step 5 Holding the blades in position, insert the beater assembly into the freezing cylinder, and slide the assembly into position over the drive shaft. Turn the beater slightly to be certain that the beater is properly seated. When in position, the beater will not protrude beyond the front of the freezing cylinder. Figure 7 Step 4 Install the beater assembly. First check scraper blades for any nicks or signs of wear. If any nicks are present or if the blade is worn, replace both blades. Figure 9 Step 6 Install the white plastic guide bearing on the short end of the torque rotor. Slide the o-ring into the groove on the long end of the torque rotor and lubricate the o-ring. Do not lubricate the guide bearing. Figure 8 If blades are in good condition, install the scraper blade clip over the scraper blade. Place the rear scraper blade over the rear holding pin (knife edge to the outside). Holding the blade on the beater, turn it over and install the front blade the same way. Figure 10 Operating Procedures 10

15 Step 7 Insert the torque rotor end with the guide bearing into the pilot hole in the center of the drive shaft. The hole in the torque rotor shaft should be rotated to the 12 o clock position. Figure 13 Step 10 Rotate the draw valve so the flats on the top of the draw valve are perpendicular to the door face. Figure 11 Step 8 Assemble the freezer door with the Ice Buster (door spout clearing device). To assemble the door with the ice buster, install the o-rings on the draw valve and lubricate. Figure 14 Step 11 Insert the ice buster through the door spout and into the slot located just above the lower o-ring. Figure 12 Step 9 Insert the draw valve into the door, leaving approximately 1/2 of the valve sticking out the top of the door. Figure Operating Procedures

16 Step 12 With the ice buster in place, rotate the draw valve to allow installation of the draw handle. This will lock the ice buster in place. Install the draw handle pin, and close the draw valve by moving the handle to the left. Step 14 Install the freezer door. Position the freezer door on the 4 studs on the front of the freezing cylinder. Install the handscrews. Tighten equally in a criss-cross pattern to insure the door is snug. Do not over-tighten. Step 15 Position the torque arm by inserting it through the slot in the torque switch arm and down into the hole in the torque rotor which protrudes from the door. Verify proper installation by moving the torque rotor back and forth to be sure it moves freely and easily. Figure 16 Step 13 Place the large rubber gasket into the groove on the back side of the freezer door. Slide the white, plastic front bearing onto the bearing hub, making certain that the flanged end of the bearing is resting against the freezer door. DO NOT lubricate the door gasket or front bearing. Figure 18 Step 16 Install the front drip pan. Slide the long drip pan into the hole in the front panel. Figure 17 Figure 19 Operating Procedures 12

17 Step 17 Install the front drip tray and splash shield beneath the door spout. Figure 20 Step 18 With sanitized hands, or a plastic sanitized glove, lay the air/mix feed tube (optional) in the bottom of the mix hopper. Figure 22 Step 3 While the solution is flowing into the freezing cylinder, brush clean the mix hopper, air/mix feed tube (optional) and mix inlet hole. Step 4 Place the power switch in the WASH position. This will agitate the sanitizing solution in the freezing cylinder. Allow the solution to agitate for five minutes. Figure 21 Sanitizing Step 1 Prepare two gallons (7.6 liters) of an approved 100 PPM sanitizing solution (example: Kay-5R). USE WARM WATER AND FOLLOW THE MANUFACTUR- ER S SPECIFICATIONS. Step 2 Pour the two gallons (7.6 liters) of sanitizing solution into the hopper and allow it to flow into the freezing cylinder. Figure Operating Procedures

18 Step 5 Place an empty mix pail beneath the door spout and move the draw handle to the right. Draw off all the sanitizing solution. When the sanitizer stops flowing from the door spout, move the draw handle to the left and place the power switch in the OFF position. Step 2 When the mix has stopped bubbling down into the freezing cylinder, install the air/mix feed tube (optional) in the mix inlet hole with the hole side down. Figure 24 Step 6 Stand the air/mix feed tube (optional) in the corner of the hopper. Figure 26 Step 3 Place the power switch in the AUTO position. When the unit cycles off, the product will be at serving viscosity. The viscosity (thickness) of the product can be adjusted by turning the viscosity adjustment screw on the upper right side under the display light. Turn the viscosity adjustment screw clockwise for a thicker product, or counterclockwise for a thinner product. After making an adjustment, allow the refrigeration system to cycle 2 or 3 times to accurately evaluate the viscosity. Figure 25 Priming Step 1 With a pail beneath the door spout, move the draw handle to the right. Pour two gallons (7.6 liters) of FRESH mix into the hopper and allow it to flow into the freezing cylinder. This will force out any remaining sanitizing solution. When full strength mix is flowing from the door spout, move the draw handle to the left. Figure Operating Procedures 14

19 Step 4 Place the mix hopper cover in position. For proper operation, there must be a substantial amount of mix in the hopper. If the ADD MIX light illuminates, refill the mix hopper as soon as possible. Step 4 If local health codes permit, empty the rerun into the rerun can. Cover the container and place it in the walk-in cooler. ALWAYS FOLLOW LOCAL HEALTH CODES Rinsing Figure 28 Closing Procedure Step 1 Pour two gallons (7.6 liters) of cool, clean water into the mix hopper. With the brushes provided, scrub the mix hopper and the mix inlet hole. To disassemble this unit, the following items will be needed: S Two cleaning pails S Necessary brushes (provided with freezer) S Cleaner S Single service towels Draining Product From The Freezing Cylinder Step 1 Place the power switch in the OFF position as far ahead of cleaning time as possible to allow frozen product to soften for easier cleaning. Step 2 Remove the hopper cover and the air/mix feed tube (if the unit is equipped with an air/mix feed tube). Take these parts to the sink for cleaning. Step 3 With a sanitized pail beneath the door spout, place the power switch in the WASH position and move the draw handle to the right. When product stops flowing from the door spout, move the draw handle to the left and place the power switch in the OFF position. Figure 29 Step 2 With a pail beneath the door spout, place the power switch in the WASH position and move the draw handle to the right. Drain all the rinse water from the freezing cylinder. When the rinse water stops flowing from the door spout, move the draw handle to the left and place the power switch in the OFF position. Repeat this procedure until the rinse water being drawn from the freezing cylinder is clear. 15 Operating Procedures

20 Cleaning Step 1 Prepare two gallons (7.6 liters) of an approved cleaning solution (example: Kay-5R). USE WARM WATER AND FOLLOW THE MANUFACTURER S SPECIFICATIONS. Step 2 Pour the two gallons (7.6 liters) of cleaning solution into the hopper and allow it to flow into the freezing cylinder. Step 3 While the solution is flowing into the freezing cylinder, brush-clean the mix hopper and mix inlet hole. Step 4 Place the power switch in the WASH position. This will agitate the cleaning solution in the freezing cylinder. Step 5 Place an empty pail beneath the door spout and move the draw handle to the right. Draw off all the cleaning solution. When the solution stops flowing from the door spout, move the draw handle to the left, and place the power switch in the OFF position. Disassembly BE SURE THE POWER SWITCH IS IN THE OFF POSITION. Failure to follow this instruction may result in severe personal injury from hazardous moving parts. Brush Cleaning Step 1 Prepare a sink with a cleaning solution (example: Kay-5R). USE WARM WATER AND FOLLOW THE MANUFACTURER S SPECIFICATIONS. (If another approved cleaner is used, dilute according to label instructions. IMPORTANT: Follow the label directions. Too STRONG of a solution can cause parts damage, while too MILD of a solution will not provide adequate cleaning.) Make sure all brushes provided with the freezer are available for brush cleaning. Step 2 Remove the o-ring and seal from the drive shaft. Remove the o-ring and the bearing from the torque rotor. Step 3 Remove the draw valve, ice buster, front bearing, and gasket from the freezer door. Remove all o-rings. Note: To remove the o-ring, use a single service towel to grasp the o-ring, and apply pressure in an upward direction until the o-ring pops out of its groove. With the other hand, push the top of the o-ring forward until it rolls out of the groove and can be removed easily. Step 4 Thoroughly brush-clean all disassembled parts in the cleaning solution, making sure all lubricant and mix film is removed. Place all the cleaned parts on a clean, dry surfacetoairdry. Step 5 Return to the freezer with a small amount of cleaning solution. Brush-clean the rear shell bearing at the back of the freezing cylinder with the black bristle brush. Step 1 Remove the torque arm, handscrews, freezer door, torque rotor, beater assembly, scraper blades and drive shaft from the freezing cylinder. Take these parts to the sink for cleaning. Step 2 Remove the front drip tray and the splash shield. Take these parts to the sink for cleaning. Step 3 Remove the rear drip pan from the front panel. Note: If the drip pan is filled with an excessive amount of mix, it is an indication the drive shaft seal should be replaced or properly lubricated. Figure 30 Step 6 Wipe clean all exterior surfaces of the freezer. Operating Procedures 16

21 Section 7 Important: 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. WE RECOMMEND DAILY CLEANING AND SANITIZING. Troubleshooting Bacterial Count: j 1. Thoroughly clean and sanitize 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 feed tube, which extends from the 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. Be sure to have a generous amount of cleaning solution on the brush. 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, then mix the rerun with fresh mix in a ratio of 50/50 during the day s operation. j 6. On a designated day of the week, run the mix as low as feasible and discard after closing. This will break the rerun cycle and reduce the possibility of high bacteria and coliform counts. j 7. 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. j 8. Temperature of mix in mix hopper and walk-in cooler should be below 40_F. (4.4_C.). Regular Maintenance Checks: j 1. Replace scraper blades that are nicked, damaged or worn down. j 2. Before installing beater, be certain the scraper blade is properly attached. j 3. Check rear shell bearing for signs of wear (excessive mix leakage in drip pan) and be certain it is properly cleaned. j 4. Using a screwdriver and cloth towel, keep the rear shell bearing and the female square drive socket clean and free of lubricant and mix deposits. j 5. Dispose of o-rings and seals if they are worn, torn, or fit too loosely, and replace with new ones. j 6. Follow all lubricating procedures as outlined in Assembly. j 7. Check the condenser(s) 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. 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 to be left unheated and subject to freezing conditions. Disconnect the freezer from the main power source to prevent possible electrical damage. Your local Taylor Distributor can perform this service for you. Wrap detachable parts of the freezer such as beater, blades, drive shaft, and freezer door, and place in a protected dry place. Rubber trim parts and gaskets can be protected by wrapping with moisture-proof paper. All parts should be thoroughly cleaned of dried mix or lubrication accumulations which attract mice and other vermin. 17 Important: Operator Checklist
