Section 1 To the Installer The following are general installation instructions. For complete installation details, please see the check out card. This unit has many sharp edges that can cause severe injuries. Installer Safety Site Preparation In all areas of the world, equipment should be installed in accordance with existing local codes. Please contact your local authorities if you have any questions. Review the area where the unit will be installed before uncrating the unit.
Air Cooled Units Electrical 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. In all other areas of the world, equipment should be installed in accordance with the existing local codes.
S S Refrigerant Appliances that are permanently connected to fixed wiring and for which leakage currents may exceed 10 mA, particularly when disconnected or not used for long periods, or during initial installation, shall have protective devices such as a GFI, to protect against the leakage of current, installed by the authorized personnel to the local codes.
Section 2 To the Operator The freezer you have purchased has been carefully engineered and manufactured to give you dependable operation. The Taylor Model 490, when properly operated and cared for, will produce a consistent quality product. Like all mechanical products, it 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.
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.
Cleaning and sanitizing schedules are governed by your state or local regulatory agencies and must be followed accordingly. Please refer to the cleaning section of this manual for the proper procedure to clean this unit. S DO NOT allow untrained personnel to operate this machine. S DO NOT operate the freezer unless all service panels and access doors are restrained with screws. S DO NOT remove any internal operating parts (example: freezer door, beater, scraper blades, etc.

Section 5 Important: To the Operator Indicator Lights: “Add Mix” / “Mix Out” Overload Mechanism The overload mechanism protects the beater motor from an overload condition. Should an overload occur, the overload mechanism will discontinue machine operation. To properly reset the freezer, place the control switch in the “OFF” position. Allow the unit to cool. Place the control switch in the “WASH” position and observe the freezer's performance. The “Mix Low” light is located on the front of the machine.
Section 6 Operating Procedures The Model 490 stores 20 quarts (18.9 liters) of mix in the hopper. The mix flows by gravity through an air tube down into the freezing cylinder. Insert the drive shaft through the rear shell bearing in the freezing cylinder and engage the hex end firmly into the gear box coupling. Instructions begin when we enter the store in the morning and find the parts disassembled and laid out to air dry from the previous night's cleaning.
If blades are in good condition, install the scraper blade clips on the scraper blades. Place the rear scraper blade over the rear holding pin on the beater (knife edge to the outside). Holding the rear blade on the beater, slide the assembly into the freezing cylinder halfway, tail end first. Install the front scraper blade over the front holding pin. Slide the beater assembly completely into the freezing cylinder. Step 3 Install the draw valve.
Step 4 Install the freezer door. Place the freezer door gasket into the groove on the back of the freezer door. Slide the front bearing over the baffle rod so the flanged edge is against the door. DO NOT LUBRICATE THE GASKET OR BEARING. Rotate the draw valve bracket to the left and center it into position by raising the draw arm and placing it into the slotted groove of the draw valve bracket. Note: The draw valve bracket must be positioned with the notch to the left.
Step 6 Slide the center drip pan into the hole in the front panel. Sanitizing Step 1 Prepare an approved 100 PPM sanitizing solution (examples: 2-1/2 gal. [9.5 liters] of Kay-5R or 2 gal. [7.6 liters] of Stera-SheenR). USE WARM WATER AND FOLLOW THE MANUFACTURER'S SPECIFICATIONS. Step 2 Pour the sanitizing solution into the hopper, and allow it to flow into the freezing cylinder. Figure 14 Step 7 Install the front drip tray and splash shield under the door spout.
Step 4 Place the control switch in the “WASH” position. This will cause the sanitizing solution in the freezing cylinder to agitate. Allow the solution to agitate for five minutes. Priming Prime the machine as close to the time of first product draw as possible. Step 1 With a mix pail beneath the door spout, raise the draw arm. Pour two gallons (7.6 liters) of FRESH mix into the hopper and allow it to flow down into the freezing cylinder. This will force out any remaining sanitizing solution.
Step 4 Place the control switch in the “AUTO” position. Rotate the draw valve and lift the draw arm to start the compressor. When the unit cycles off, the product will be at serving temperature. Draining Product from the Freezing Cylinder Step 1 Place the control switch in the “OFF” position. Step 2 Remove the hopper cover, gasket, and air tube. Take these items to the sink for cleaning.
Rinsing Disassembly Step 1 Pour two gallons (7.6 liters) of cool, clean water into the mix hopper. With the brushes provided, scrub the mix hopper, mix inlet hole, and mix level sensing probes. Note: Failure to remove, brush clean and air dry these items, will result in damage to the related components. Step 1 BE SURE THE CONTROL SWITCH IS PLACED IN THE “OFF” POSITION. Step 2 With a mix pail beneath the door spout, place the control switch in the “WASH” position and raise the draw arm.
Step 4 Remove the draw valve from the freezer door. Remove the two o-rings from the draw valve. Step 6 Return to the freezer with a small amount of cleaning solution. With the black bristle brush, brush clean the rear shell bearing at the back of the freezing cylinder. Note: To remove o-rings, use a single service towel to grasp the o-ring. Apply pressure in an upward direction until the o-ring pops out of its groove.
Section 7 Important: Operator Checklist j 6. 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 solution may not do an adequate job of cleaning or sanitizing. During Cleaning and Sanitizing ALWAYS FOLLOW LOCAL HEALTH CODES. Cleaning and sanitizing schedules are governed by federal, state, or local regulatory agencies, and must be followed accordingly.
j 7. Follow all lubricating procedures as outlined in “Assembly”. Winter Storage To protect the freezer during the winter months when the place of business is closed, it is important that certain precautions be followed; 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. On water-cooled units, disconnect the water supply.
