Air Cooled Units

DO NOT obstruct air intake and discharge openings:

Air cooled units require a minimum of 6” (152 mm) of clearance on both sides of the freezer. It is recommended to place the rear of the unit against the wall to prevent recirculation of warm air. Failure to allow adequate clearance can reduce the refrigeration capacity of the freezer and possibly cause permanent damage to the compressors.

Water Connections

(Water Cooled Units Only)

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. Please contact your local authorities.

FOLLOW YOUR LOCAL ELECTRICAL CODES!

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 electrical box for proper power connections.

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 opentrapdrain.

A back flow prevention device is required on the incoming water connection side.

Please refer to the applicable National, State, and local codes for determining the proper configuration.

CAUTION: THIS EQUIPMENT MUST BE PROPERLY GROUNDED! FAILURE TO DO SO CAN RESULT IN SEVERE PERSONAL INJURY FROM ELECTRICAL SHOCK!

This unit is provided with an equipotential grounding lug that is to be properly attached to the rear of the frame by the authorized installer. The installation location is marked by the equipotential bonding symbol (5021 of IEC 60417-1) on both the removable panel and the equipment's frame.

S Stationary appliances which are not

equipped with a power cord and a plug or another 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.

110328

Model 490To the Installer

S 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.

S Supply cords used with this unit shall be

oil-resistant, sheathed flexible cable not lighter than ordinary polychloroprene or other equivalent synthetic elastomer-sheathed cord (Code designation 60245 IEC 57) installed with the proper cord anchorage to relieve conductors from strain, including twisting, at the terminals and protect the insulation of the conductors from abrasion.

Beater Rotation

Refrigerant

In consideration of our environment, Taylor proudly uses only earth friendly HFC refrigerants. The HFC refrigerant used in this unit is R404A. This refrigerant is generally considered non-toxic and non-flammable, with an Ozone Depleting Potential (ODP) of zero (0).

However, any gas under pressure is potentially hazardous and must be handled with caution.

NEVER fill any refrigerant cylinder completely with liquid. Filling the cylinder to approximately 80% will allow for normal expansion.

Refrigerant liquid sprayed onto the skin may cause serious damage to tissue. Keep eyes and skin protected. If refrigerant burns should occur, flush immediately with cold water. If burns are severe, apply ice packs and contact a physician immediately.

Beater rotation must be clockwise as viewed

looking into the freezing cylinder. Note: The following procedures must be performed

by an authorized Taylor service technician. To correct the rotation on a three-phase unit,

interchange any two incoming power supply lines at freezer main terminal block only.

To correct rotation on a single-phase unit, change the leads inside the beater motor. (Follow the diagram printed on the motor.)

Electrical connections are made directly to the terminal block provided in the main control box.

Taylor reminds technicians to be cautious of government laws regarding refrigerant recovery, recycling, and reclaiming systems. If you have any questions regarding these laws, please contact the factory Service Department.

WARNING: R404A refrigerant used in conjunction with polyolester oils is extremely moisture absorbent. When opening a refrigeration system, the maximum time the system is open must not exceed 15 minutes. Cap all open tubing to prevent humid air or water from being absorbed by the oil.

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.

The Operator's Manual should be read before operating or performing any maintenance on your equipment.

The Model 490 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 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: 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.

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, 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 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 is 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 Taylor Distributor or the Taylor Factory. Be prepared to provide the Model/Serial Number of the unit in question.

Section 5 Important: To the Operator

Indicator Lights: “Add Mix” / “Mix Out”

The “Mix Low” light is located on the front of the machine. When the light is flashing, it indicates that the mix hopper has a low supply of mix and should be refilled as soon as possible. The Model 490 utilizes a “Mix Out” light. When flashing, it indicates there is no mix in the hopper and the compressor stops running until mix is replenished. This eliminates possible damage to the beater, blades, drive shaft and door.

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.

Note: If an overload condition occurs while the unit is operating in the “AUTO” mode, the unit will not return to the “AUTO” mode once the overload has reset. The draw handle must be lifted before the unit will return to AUTO. Likewise, if power is restored to a unit following a power interruption, it is necessary to raise the draw handle to resume “AUTO” operation.

The overload is inherent in the beater motor. There is no manual reset.

Model 490 Important: To the Operator

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.

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.

The following procedures will show you how to assemble the parts into the freezer, sanitize them, and prime the freezer with fresh mix in preparation to serve your first product.

If you are disassembling the machine for the first time, or need information to get to this starting point in our instructions, turn to the “Disassembly” instructions in this manual and start there.

Assembly

Note: When lubricating parts, use an approved food

grade lubricant (Example: Taylor Lube).

Step 1 Install the drive shaft. Slide the o-ring into the first

groove on the drive shaft. Lubricate the groove and the 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. Fill the inside portion of the seal with 1/4” more lubricant and evenly lubricate the flat side of the seal that comes in contact with the bearing.

Insert the drive shaft through the rear shell bearing in the freezing cylinder and engage the hex end firmly into the gear box coupling.

Step 2

With a mix pail beneath the door spout, place the control switch in the “WASH” position and raise the draw arm. Drain all the rinse water from the freezing cylinder. When the rinse water stops flowing from the door spout, lower the draw arm and place the control switch in the “OFF” position.

Repeat this procedure until the rinse water being drawn from the freezing cylinder is clear.

Cleaning

Step 1

Prepare an approved 100 PPM cleaning 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.

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

Remove the handscrews, freezer door, gasket, front bearing, beater, scraper blades, and drive shaft from the freezing cylinder. Take these items to the sink for cleaning.

Step 3

Remove the drip pan from the machine. Note: If the drip pan is filled with an excessive

amount of mix, this indicates that the drive shaft seal and o-ring should be replaced or was improperly lubricated.

Step 4

Remove the front drip tray and splash shield.

Brush Cleaning

Step 2

Pour the 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, mix inlet hole and mix level sensing probes.

Step 4

Place the control switch in the “WASH” position. This will cause the cleaning solution in the freezing cylinder to agitate.

Model 490Operating Procedures

Step 4

Remove the draw valve from the freezer door. Remove the two o-rings from the draw valve.

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. With the other hand, push the top of the o-ring forward, and it will roll out of the groove and can be easily removed. If there is more than one o-ring to be removed, always remove the rear o-ring first. This will allow the o-ring to slide over the forward o-rings without falling into the open grooves.

Step 5

Thoroughly brush clean all disassembled parts in the cleaning solution, making sure all lubricant and mix film is removed. Take particular care to brush clean the draw valve core in the freezer door. Place all the cleaned parts on a clean dry surface to air dry overnight.

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.

Model 490 Operating Procedures

Section 7 Important: Operator Checklist

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. If the unit has a “Standby mode”, it must not be used in lieu of proper cleaning and sanitizing procedures and frequencies set forth by the ruling health authority. The following check points should be stressed during the cleaning and sanitizing operations.

CLEANING AND SANITIZING MUST BE

PERFORMED DAILY.

Troubleshooting Bacterial Count

j 1. Thoroughly clean and sanitize the 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 up to the rear of the freezing cylinder.

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.

j 7. The temperature of the mix in the mix hopper

and walk-in cooler should be below 40_F. (4.4_C.).

Regular Maintenance Checks

j 1. Rotate the scraper blades to allow both sides

of the knife edge to wear evenly. This will contribute to self-sharpening and help maintain fast, efficient freezing.

j 2. Replace scraper blades that are bent,

damaged, or worn down.

j 3. Before installing the beater, be certain that the

scraper blades are properly attached over the beater pins, and into the blade clip.

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 4. Dispose of o-rings and seals that are worn,

torn, or fit too loosely, and replace with new ones.

j 5. Check the rear shell bearing for signs of wear

(excessive mix leakage in rear drip pan) and be certain it is properly cleaned.

j 6. Using a screwdriver and cloth towel, keep the

female drive socket and the rear shell bearing free of lubricant and mix deposits.

Model 490Important: Operator Checklist

j 7. Follow all lubricating procedures as outlined in

“Assembly”.

j 8. On air-cooled units, check the condenser for

an accumulation of dirt and lint. Dirty condensers will reduce the efficiency and capacity of the machine. The condensers should be cleaned monthly. Remove the side panels to gain access to the condensers. Use a soft brush to clean between the fins of the condenser. 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 9. On water-cooled units, 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 mechanic.

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. Use air pressure to blow out any remaining water in the condensers. This is extremely important. Failure to follow this procedure can cause severe and costly damage to the refrigeration system.

Your local Taylor Distributor can perform this service for you.

Wrap detachable parts of the freezer such as the beater assembly 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 accumulations which attract mice and other vermin.
