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.

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.

Air Cooled Units

DO NOT obstruct the unit’s air intake and discharge openings:

Model 702 units require a minimum of 3” (76 mm) clearance on both sides, and 6” (152 mm) on the back.

Model 772 units require a minimum of 3” (76 mm) clearance around all sides of the freezer. This is necessary 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.

Note:

This chart applies to units using 502 or 404A refrigerant.

Water Cooled:

High side pressure for water cooled units is determined by the water valve. The water valve is factory set to maintain a high pressure of 235 PSI

(1,620 kPa.). To adjust the high pressure, place the gauge on the high side access port. Turn the adjustment knob on the water valve clockwise to lower the high side pressure and counterclockwise to raise the pressure.

The high side pressure switch is factory set at 440 PSI

(3,034kPa) for 404A/HP62. In the event of a water loss, this switch will sense a rise in pressure and deactivate the freezer.

Check Out

Once the unit is installed, it is advisable to check the following controls and mechanical operations of the freezer and to make any necessary adjustments. If applicable, repeat these checks for the second freezing cylinder on double head units.

Controls

Place the control switch in the “AUTO” position. The main refrigeration system will operate (compressor, beater motor, and the condenser fan). The dial light and the mix low indicator will be lit.

Figure 1

If the freezer is water cooled, the automatic water valve will begin to open and cold water will flow into the condenser. This will remove heat from the refrigerant.

As the water flows into the open trap drain, it should be warm to the touch. Place the control switch in the

“OFF” position.

Beater Rotation

Beater rotation must be clockwise as viewed looking into the freezing cylinder.

Beater rotation must be clockwise as viewed looking into the freezing cylinder.

To correct rotation on a three- phase unit, interchange any two incoming power supply lines at the freezer main terminal block only.

To correct rotation on a single- phase unit, exchange 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 located behind the upper left side panel for the Model 702, and behind the service panel for the Model 772.

Note:

Electrical connections should be performed by a trained service technician.

Gear Alignment

To prevent costly parts damage and to prevent excessive mix leakage, the gear unit must be perfectly aligned. To check gear alignment, insert the drive shaft through the rear shell bearing and into the gear unit.

Move the drive shaft in and out of the gear unit, using all positions of the hex end. If any binding of the drive shaft occurs, the gear unit could be out of alignment.

Inspect the bolts which mount the gear unit. make sure they are tightened down.

To prevent excessive mix leakage, check the rear shell bearing. The locking tab should be folded over the nut to prevent the nut from working loose.

Thermistor Probe (Part # 038061- BLK)

The resistance value of the thermistor probe corresponds with the product temperature in the freezing cylinder. As the product becomes colder, the probe resistance increases. As the product becomes warmer, the probe resistance decreases.

Approximate probe resistance readings:

1. 10,000 ohms at room temperature (78

Thermistor Control

Operation

The thermistor probe is positioned in the bulb- well located at the front of the freezing cylinder. The thermistor control becomes operational when powered by the 24 VAC transformer.

When the desired product is achieved (control set- point) the thermistor control relay opens and discontinues the power sent to the compressor relay coil.

When the product in the freezing cylinder reaches 2

_

F.

(1

_

C.) above the control set- point, the thermistor relay closes, sending L1 power to the compressor relay coil.

The refrigeration system will run until the control set- point is achieved.

Anticipator

The anticipator signals the thermistor control to activate the refrigeration system whenever product is drawn. As the draw valve is raised (freezer draw switch closes), continuity is created between the thermistor control anticipator terminals. The thermistor control relay will close within 1 second to start the refrigeration system.

Upon completing the draw, the thermistor control recognizes the loss of continuity between the anticipator terminals, but will continue refrigeration for at least 25 seconds. This allows for additional blending and freezing of the warmer mix which has entered the freezing cylinder. After approximately 25 seconds have elapsed, the thermistor control returns to normal operation and cycles off the refrigeration system when the set- point temperature is achieved.

Setting Temperature

1. Position the thermistor fine adjustment at mid- range. This will limit the fine adjustment temperature range to



2

_

F. (



1

_

C.).

2. Turn the coarse adjustment clockwise to the coldest setting.

3. With the freezer correctly primed, place the control switch in the “AUTO” position.

4. After the appropriate freezing time, test the product temperature. When a sample portion temperature is approximately 1

_ above the desired temperature setting, slowly turn the coarse adjustment counterclockwise (warmer) until the refrigeration system cycles off.

5. Allow the refrigeration system to cycle through at least two “off” cycles. After the unit cycles off, draw a sample of product and check the temperature. Readjust the coarse adjustment as required, but make only small adjustments.

Note:

The anticipator automatically activates the refrigeration system 0 - 1 second after the draw valve is opened. If several small samples are drawn, the temperature may drift lower. To accurately set the control, let the product temperature stabilize by allowing the thermistor control to cycle the freezer on and off by the control set point instead of the anticipator.

Service Tips

If a problem arises with the thermistor control assembly, identify and replace only the faulty component. For example, if the probe is defective, replace only the probe.

A varistor must be connected to the thermistor control’s 24 VAC terminals in order to protect the control from voltage spikes (varistor part number

X31547).

Fill the bulb- well with automotive antifreeze before installing the thermistor probe, and be sure the probe is installed completely into the bottom of the bulb- well.

Note:

Lower the probe to the point where the wires extend from the probe and a resistance is felt. This indicates the probe is installed completely in the bottom of the bulb- well.

If the thermistor relay which

starts

the compressor will not close, check the following items:

ELECTRICAL SHOCK AREA! USE CAUTION!

1. Make sure power is being supplied to the freezer and that all operating switches are in the correct position.

2. Using a voltmeter, check the voltage supply to the thermistor control. The control requires 24 volts to operate.

3. Using an ohmmeter, check probe resistance.

(Refer to the thermistor curve chart on page 7 for proper readings.)

If the thermistor relay which

deactivates

the compressor will not open, check the following items:

ELECTRICAL SHOCK AREA! USE CAUTION!

1. Make sure the thermistor relay opens when the freezer control switch is in the “OFF” position.

2. Make sure the thermistor probe is connected to the correct probe terminals.

3. Using an ohmmeter, check the thermistor probe for proper resistance. (Refer to the thermistor curve chart on page 7 for proper readings.)

4. Disconnect one wire to an anticipator terminal.

If the thermistor relay opens after approximately 25 seconds, the problem is in the anticipator wiring circuit.

When problems such as erratic product quality occur, it is of utmost importance to determine if the thermistor components are defective before replacing them.

See page 34 for Troubleshooting Thermistor

Components.

Section 4

The freezer you have purchased has been carefully engineered and manufactured to give you dependable operation. The Taylor freezer, when properly operated and cared for, will produce a consistent quality product.

Like all mechanical products, this machine 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 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 review these procedures in order to be properly trained and to make sure that there is no confusion.

In the event that you should require technical assistance, please contact your local authorized

Taylor Distributor.

Note:

Your Taylor warranty is valid only if the parts are authorized Taylor parts, purchased from the local authorized Taylor Distributor, and only if all required service work is provided by an authorized Taylor service technician. Taylor reserves the right to deny warranty claims on units or parts if non- Taylor approved parts or incorrect refrigerant were installed in the unit, system modifications were performed beyond factory recommendations, or it is determined that the failure was caused by abuse, misuse, neglect, or failure to follow all operating instructions. For full details of your Taylor Warranty, please see the Limited

Warranty section in this manual.

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.

Models 702 & 772

13

To the Operator

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 unit are warranted for the term stated in the Limited Warranty section in this manual. 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 unit’s refrigeration system,

only the refrigerant specified on the affixed data label should be used

. The unauthorized use of alternate refrigerants will void your Taylor compressor warranty. It is the unit 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.

The freezer you have purchased uses refrigerants 404a and 134a. These “ozone friendly” refrigerants comply with the U.S. Clean

Air Act of 1990.

Section 7 Important: To the Operator

Indicator Light “Mix Low”

The Models 702 and 772 are equipped with a “MIX

LOW” light located on the front of the machine. When the light begins to flash, it indicates that the mix hopper has a low supply of mix. At this time, the hopper should be filled with mix. If you neglect to add mix when the light begins to flash, eventual damage to the beater, blades, drive shaft, and freezer door may occur.

Control Switch

The center position is “OFF”. The

right

position is

“AUTO”, which activates the beater motor and the refrigeration system. The

left

position is “WASH” which activates the beater motor only.

Figure 2

Symbol Definitions

The following chart identifies the symbol definitions used on the operator switches.

= The “WASH” keypad.

= The “OFF” keypad.

Figure 3

Reset Button

On a Model 702, the reset button is located under the left upper side panel. On the Model 772, the reset button is located on the lower front panel.

The reset button protects the beater motor from an overload condition. If an overload occurs, the reset mechanism will trip. To properly reset the freezer, place the control switch in the “OFF” position. Press the reset button firmly. Place the control switch in the

“WASH” position and observe the freezer’s performance. Once satisfied, place the control switch back in the “AUTO” position.

not

be used in lieu of daily disassembly, cleaning, and sanitizing. Follow your local health codes regarding this issue.

Important: To the Operator

Section 8

The Model 702 has been selected to show you the pictured step- by- step operating procedures for both models contained in this manual. These two models, for practical purposes of operation, are the same.

They both store 20 quarts (18.9 liters) of mix in the hopper. The mix then flows

by gravity

through a mix feed tube down into the freezing cylinder.

Locate your model number below to determine the characteristics of your freezer:

702: (1) 4 quart (3.8 liter) freezing cylinder.

772: (2) 7 quart (6.6 liter) freezing cylinders.

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.

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 portion.

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 27, “Disassembly” and start there.

Operating Procedures

Assembly

Figure 6

Step 2

Install the beater assembly. First check the scraper blade(s) for any nicks or signs of wear. If any nicks are present, replace the blade(s).

MAKE SURE THE CONTROL SWITCH IS IN

THE “OFF” POSITION TO ELIMINATE THE

CHANCE OF MOVING PARTS.

Note:

When lubricating parts, use an approved food grade lubricant (example: Taylor Lube).

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 fits 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.

090303


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 that the drive shaft seal should be replaced or was improperly lubricated.



Step 4

Remove the front drip tray and the splash shield.

Brush Cleaning

Step 1

Prepare a sink with an approved cleaning solution

(examples: Kay- 5

R or Stera- Sheen

R

). USE WARM

WATER AND FOLLOW THE MANUFACTURER’S

SPECIFICATIONS

If an approved cleaner other than Kay- 5

R or

Stera- Sheen

R is used, dilute it according to the label instructions.

IMPORTANT:

Follow the label directions.

Too STRONG of a solution can cause parts damage.

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 seal(s) from the drive shaft(s).

Step 3

From the freezer door(s) remove:

S the gasket(s)

S the front bearing(s)

S the design cap(s)

S the draw valve(s)

Remove all o- rings.

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. 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 rings without falling into the open grooves.

Step 4

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(s). Place all the cleaned parts on a clean dry surface to air dry overnight.

Step 5

Return to the freezer with a small amount of cleaning solution. With the black bristle brush, brush clean the rear shell bearing(s) at the back of the freezing cylinder(s).

During Cleaning and Sanitizing


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.

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. The temperature of the mix in the mix hopper and walk- in cooler should be below 40

_

F.

(4.4

_

C.).

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 inlet hole which extends from the mix 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 there is 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 is used the following day. DO

NOT prime the machine with rerun. When using rerun, skim off the foam and discard, then mix

j

1. Rotate 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 nicked, damaged or worn.

j

3. Before installing the beater, be certain that scraper blades are properly attached over the pins.

j

4. Check the rear shell bearing for signs of wear

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

j

5. 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.

090303

Important: Operator Checklist

j

6. Dispose of o- rings and seals if they are worn, torn, or fit too loosely, and replace with new ones.

j

7. Follow all lubricating procedures as outlined in

“Assembly”.

j

8. 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

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 technician.

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 subject to freezing conditions.

Disconnect the freezer from the main power source to prevent possible electrical damage.

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.

This is extremely important.

Failure to follow this procedure may 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, blades, drive shaft, and freezer door. Place these parts 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.

Troubleshooting Thermistor

Components

Step 1

Power Switch in the “AUTO” Position

Using a voltmeter, check the two terminals connecting the transformer wires to the controller. There should be a reading of 24 volts (

¦

15%); if not, the transformer is not receiving line voltage or the transformer is faulty and should be replaced. If a proper reading is obtained, proceed to the next step.

Step 2


Using a voltmeter, make certain L1 power is being supplied to the common terminal of the controller. A reading of line voltage should be obtained. To accomplish this, measure voltage between the common terminal and any L2 power source. If a proper reading is not obtained, make sure there is line voltage at the incoming power supply. If there is incoming power, back track from the common terminal (L1) and determine where L1 is being interrupted and correct accordingly. If a proper reading is obtained, proceed to the next step.

Step 3


Remove the probe wires from the controller. Place a wire between the two probe terminals of the controller to short the component. This should activate the compressor. If this procedure does not activate the compressor, check for line voltage. If there is line voltage at the compressor contactor coil, the controller is acceptable.

Step 4

Power Switch in the “OFF” Position

Check the probe resistance. Disconnect both the yellow and black wires at the control, and measure their resistance with an ohmmeter. At room temperature, a reading of approximately 10,000 ohms should be obtained. If these readings are not obtained, replace the probe. When replacing the probe, fill the bulb- well with antifreeze. Connect the yellow wire to the white terminal and the black wire to the black terminal.

Step 5

Power Switch in the “OFF” Position

Check the anticipator microswitch by removing the wires connecting the switch to the controller, and check for continuity. If switch continuity exists when the draw handle is raised, the switch is effective.

Continuity should break when the draw handle is lowered.

FUNCTION

Provides circulation of refrigerant.

Condenses refrigerant from a vapor to a liquid by removing heat from the refrigerant.

Removes foreign matter and moisture from the refrigerant.

Meters liquid refrigerant from the liquid line into the insulated shell evaporator.

Insulated evaporator providing freezing and storage of product.

Controls pressure in the hopper evaporator.

When the coil is energized, the relay closes. This permits power to flow to the overload relay, then to the beater motor.

When the coil is energized, the relay closes. This permits power to flow to the compressor.

When in “WASH”, the control switch permits power to travel to the beater line starter. When in “AUTO”, it permits power to travel to the thermistor control.

Monitors product in the freezing cylinder. When the product begins to get warm, the thermistor control allows power to flow to the compressor relay.

Powers the thermistor control.

Activates the “MIX LOW” light when the mix level in the hopper becomes inadequate.

When the draw arm is raised, a micro switch closes and sends a signal to the thermistor control.

Controls the flow of water to the condenser by sensing the increasing and decreasing pressures at the high side of the compressor.

Senses high head pressure at the compressor. In the event of a high pressure situation, the switch breaks power to the control switch and the freezer shuts down.

Dissipates heat from the interior of the freezer.

Circulates air across the condenser.

Drives the gear unit which in turn rotates the beater assembly.

Removes impurities from the refrigerant prior to the dryer.

Used on high voltage units to reduce incoming voltage down to 230 volts to power the control circuitry.
