Compressor Warranty Disclaimer

The refrigeration compressor(s) on this machine arewarranted for the term indicated on the warrantycard accompanying this machine. However, due tothe Montreal Protocol and the U.S. Clean Air ActAmendments of 1990, many new refrigerants arebeing tested and developed; thus seeking their wayinto the service industry. Some of these newrefrigerants are being advertised as drop-inreplacements for numerous applications. It shouldbe noted that in the event of ordinary service to thismachine's refrigeration system, only the refrigerantspecified on the affixed data label should be used.The unauthorized use of alternate refrigerants willvoid your compressor warranty. It will be the owners'responsibility to make this fact known to anytechnicians they employ.

It should be noted that Taylor does not warrant therefrigerant used in its equipment. For example, if therefrigerant is lost during the course of ordinaryservice to this machine, Taylor has no obligation toeither supply or provide its replacement, either atbillable or unbillable terms. Taylor does have theobligation to recommend a suitable replacement ifthe original refrigerant is banned, obsoleted, or nolonger available during the five year warranty of thecompressor.

Taylor will continue to monitor the industry and testnew alternate refrigerants as they are beingdeveloped. Should a new alternate prove, throughour testing, that it would be accepted as a drop-inreplacement, then the above disclaimer wouldbecome null and void. To find out the current statusof an alternate refrigerant as it relates to yourcompressor, call the local Taylor Distributor or theTaylor Factory. Be prepared to provide themodel/serial number of the unit in question.

Thermistor Control

Function

The thermistor control maintains producttemperature in the freezing cylinder by monitoringthe resistance of the thermistor probe.

Thermistor Probe (038061--20)

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

Approximate probe resistance readings:

S 10,000 OHMS at room temperature(77°F/25°C)

S 46,012 OHMS at product temperature(20°F/-6.6°C)

Operation

The thermistor probe is positioned in the bulb-welllocated at the front of the freezing cylinder. Thethermistor control becomes operational whenpowered by the 24 VAC transformer.

When the desired product is achieved (controlset-point), the thermistor control relay relaxes anddiscontinues sending L1 power to the compressorrelay coil.

When the product in the freezing cylinder warms up.5°F (.3°C) above the control set-point, thethermistor control relay closes, sending L1 power tothe compressor relay coil. The refrigeration systemwill run until the control set-point is achieved.

Anticipator

The anticipator signals the thermistor control toactivate the refrigeration system whenever productis drawn. As the draw valve is raised and the freezerdraw switch closes, continuity is created betweenthe thermistor control anticipator terminals. Thethermistor control relay will close within .5 secondsto start the refrigeration system. The control setpoint will shift 8°F (4.4°C) approximately 5 secondsafter the draw switch is released. The set point shiftwill change 3.5°F (2°C) and remain in that state for20 seconds. The set point will then return to itsoriginal setting.

Setting Temperature

1. Position the thermistor fine adjustment atmid-range. This will limit the fine adjustmenttemperature range to ±2_F (±1_C).

2. Turn the coarse adjustment clockwise to thecoldest setting.

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

4. After the appropriate freezing time, test theproduct temperature. When a sample portiontemperature is approximately 1_ above thedesired temperature setting, slowly turn thecoarse adjustment counterclockwise (warmer)until the refrigeration system cycles off.

5. Allow the refrigeration system to cycle throughat least two “off” cycles. After the unit cyclesoff, draw a sample of product and check thetemperature. Readjust the coarse adjustmentas required, but make only small adjustments.

Note: The anticipator automatically activates therefrigeration system within 5 seconds after the drawvalve is opened. If several small samples are drawn,the temperature may drift lower. To accurately setthe control, let the product temperature stabilize byallowing the thermistor control to cycle the freezeron and off by the control set-point, not theanticipator.


Service TipsIf a problem arises with the thermistor controlassembly, identify and replace only the faultycomponent. For example, if the probe is defective,replace only the probe.

S A varistor must be connected to thethermistor control 24 VAC terminals in orderto protect the control from voltage spikes(varistor part number X31547).

S Fill the bulb-well with antifreeze beforeinstalling the thermistor probe.

S Be sure the probe is installed completelyinto the bottom of the bulb-well.

Note: Lower the probe to the point where the wiresextend from the probe and a resistance is felt. Thisindicates the probe is installed completely in thebottom of the bulb-well.

If the thermistor relay which starts the compressorwill not close, check the following items:

ELECTRICAL SHOCK AREA! USE CAUTION!

1. Make sure power is being supplied to thefreezer and that all operating switches are inthe correct position.

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

3. Using an ohmmeter, check probe resistance.(Refer to the thermistor curve chart on page 14for proper readings.)

If the thermistor relay which deactivates thecompressor will not open, check the following items:

ELECTRICAL SHOCK AREA! USE CAUTION!

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

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

3. Using an ohmmeter, check the thermistor probefor proper resistance. (Refer to the thermistorcurve chart on page 14 for proper readings.)

4. Disconnect one wire to an anticipator terminal.If the thermistor relay opens afterapproximately 25 seconds, the problem is in theanticipator wiring circuit.

When problems such as erratic product qualityoccur, it is of utmost importance to determine if thethermistor components are defective beforereplacing them.

Maintaining Quality

Operation Tips

To achieve the highest quality product, the followingare key operation procedures:

1. The machine should be primed with 2 gallons(7.6 liters) of fresh mix. Rerun should be addedto the machine only before a rush period. Onepart rerun mix should be mixed with two partsfresh mix. Always skim the foam off the top ofthe rerun. In addition, make certain that allrerun is completely liquid before use; frozenparticles in the mix may plug the feedassembly. To minimize beating time, start themachine as close to opening time as possible.

2. Freeze down will take approximately 7 minutes.Afterwards, the product should be 20_F(-6.7_C) ± 1_.

3. It is possible to “outdraw” this unit. If the unit isoutdrawn, it should be given a chance torecover, or inferior product will be served.Outdrawing the unit can starve the cylinder ofmix and can cause mechanical damage.Always make certain there is mix in the hopper.

4. If the unit is air cooled, the condenser must bekept clean. A clogged condenser will result inexcessively long run times. The condensershould be inspected regularly and brushedclean when dirty.

5. Sharp and proper size scraper blades are ofcritical importance. If the blades are nicked orworn, they must be replaced, or poor scrapingand inefficient freezer operation will result.

6. O-rings and plastic scraper blades should bereplaced every three months. If at any time thescraper blades are worn to less than 15/16”,they should be replaced.

Troubleshooting Thermistor Components

Figure 4Step 1Power Switch in the “AUTO” Position

Using a voltmeter, check the two terminalsconnecting the transformer wires to the controller.There should be a reading of 24 volts (¦15%); ifnot, the transformer is not receiving line voltage orthe transformer is faulty and should be replaced. If aproper reading is obtained, proceed to the next step.

Step 2Power Switch in the “AUTO” Position

Using a voltmeter, make certain L1 power is beingsupplied to the common terminal of the controller. Areading of the line voltage should be obtained. Toaccomplish this, measure the voltage between thecommon terminal and any L2 power source. If aproper reading is not obtained, make sure there isline voltage at the incoming power supply. If there isincoming power, back track from the commonterminal (L1) and determine where L1 is beinginterrupted and correct accordingly. If a properreading is obtained, proceed to the next step.

Step 3Power Switch in the “AUTO” Position

Remove the probe wires from the controller. Place awire between the two probe terminals of thecontroller to short the component. This should

activate the compressor. If this procedure does notactivate the compressor, check for line voltage. Ifthere is line voltage at the compressor contactorcoil, the controller is acceptable.

Step 4Power Switch in the “OFF” Position

Check the probe resistance. Disconnect both thewhite (yellow) and black wires at the control, andmeasure their resistance with an ohmmeter. At roomtemperature, a reading of approximately 10,000ohms should be obtained. At product temperature, areading of approximately 46,000 ohms should beobtained. If these readings are not obtained, replacethe probe. When replacing the probe, fill thebulb-well with antifreeze. Connect the white (yellow)wire to the white terminal and the black wire to theblack terminal.

Step 5Power Switch in the “OFF” Position

Check the anticipator microswitch by removing thewires connecting the switch to the controller andcheck for continuity. If switch continuity exists whenthe draw handle is raised, the switch is effective.Continuity should break when the draw handle islowered.

Overrun

During the freezing process, mix is blended andfrozen with air. The frozen mix absorbs air andtherefore increases the volume of the mix.

Example: If 1 gallon of mix yields 1.5 gallons offrozen product, the mix volume has been increasedby 50 percent. The overrun is then 50%.

Calculating Overrun

1. Place a cup on a scale and adjust the scale toread “ZERO”.

Figure 5

2. Fill the cup completely with unfrozen fresh mixand weigh the cup of mix. Write down theweight. Discard the liquid mix and rinse the cup.

Figure 6

3. After the freezer has completed a refrigerationcycle, draw frozen product into the same cup.As the cup fills, lightly pack the product toprevent air pockets. Slightly overfill the cup andthen close the freezer draw valve.

4. Skim off the excess product at the brim of thecup.

Figure 7

5. Place the cup of frozen product on the scaleand record the weight.

Figure 8

6. Divide the unfrozen fresh mix weight by thefrozen product weight. The answer indicatesthe increase in volume.

Evaporator Oil

If the unit refrigeration cycle runs longer thannormal, this indicates a possible oil-loggedevaporator coil. An oil-logged evaporator is usuallycaused by a bent beater, worn or bent scraperblades, a faulty expansion valve, or an overchargeof refrigerant.

To remove oil from an evaporator, follow thesesteps:

1. Remove all mix and product from the freezerand allow the freezing cylinder to warm slowlyto room temperature.

2. With the freezing cylinder fully assembled (i.e.,beater and scraper blades in place), fill thehopper with hot water and place the machine inthe “AUTO” mode.

Figure 9

The hot water will cause the refrigerant in thefreezing cylinder walls to “boil” rapidly, removing theoil and returning it to the compressor.

3. Turn the automatic expansion valve clockwiseto approximately 10 PSI above its originalsetting. This will increase the ability of therefrigerant to flow across the evaporator.

4. Periodically pull the draw valve and check thewater temperature. When the water becomescool, draw the remainder of the cool water fromthe machine. This will allow more hot water toflow into the freezing cylinder.

Figure 10

5. Repeat the last step three times.

6. Adjust the automatic expansion valve setting toits original setting:R404A = 20 - 22 psi (138 - 152 kPa)

Important: Do Not Leave the Unit UnattendedDuring This Procedure!


Rear Bearing Unit Alignment

During rear bearing unit installation, it will benecessary to properly align the new component.

Tools Required:

1. Hex Alignment (Shaft) - Part Number X14407.

Figure 11

2. Alignment Disc (Hub Assembly) - Part NumberX26415.

Figure 12

Procedure:

Step 1Disconnect the main power supply to the freezer.

Step 2Remove the belt and the direct drive pulley.

Step 3Loosen the mounting bolts that secure the rearbearing unit to the frame.

Step 4Insert the alignment tool (shaft), hex end first,through the freezing cylinder. Engage the hex endfirmly into the direct drive coupling.

Step 5Slide the alignment disc onto the alignment tool(shaft) and slide it 1 inch (25.4 mm) into the front ofthe freezing cylinder.

Step 6Evenly tighten the mounting bolts which hold therear bearing unit in place. Be sure the alignment toolremains firmly engaged throughout the procedure.

Step 7Tighten the mounting bolts that secure the gear unitto the frame.

Step 8Install the direct drive pulley and belts. Check forproper pulley alignment. (See page 26.)

Step 9Remove the alignment tools from the unit. Verify thatthe drive shaft can be easily installed and removedfrom the drive coupling.


Pulley Alignment______________________________

Pulley alignment is to be performed only after properrear bearing unit alignment has been established.

1. Loosen the direct drive pulley.

2. Use a straight, flat bar and hold it firmly againstthe large rear bearing unit pulley.

Figure 13

3. Adjust the direct drive pulley until it is flush withthe motor pulley.

Figure 14

4. Tighten the direct drive pulley set screw.

If the belt does not fit within the groove of themotor pulley, re-adjust the direct drive pulleyuntil a proper fit is achieved.

Preventative Maintenance

During Cleaning and Sanitizing:

Cleaning and sanitizing schedules are governedby federal, state, or local regulatory agencies,and must be followed accordingly. If the unithas a “Standby mode”, it must not be used inlieu of proper cleaning and sanitizingprocedures and frequencies set forth by theruling health authority. The following checkpoints should be stressed during the cleaningand sanitizing operations.

CLEANING AND SANITIZING MUST BEPERFORMED DAILY.

ALWAYS FOLLOW LOCAL HEALTH CODES.

Troubleshooting Bacterial Count

j 1. Thoroughly clean and sanitize the machineregularly, including complete disassembly andbrush cleaning.

j 2. Use all brushes supplied for thorough cleaning.The brushes are specially designed to reach allmix passageways.

j 3. Use the white bristle brush to clean the mix feedtube.

j 4. Use the black bristle brush to thoroughly cleanthe rear shell bearing located at the rear of thefreezing cylinder. Be sure to have a generousamount of cleaning solution on the brush.

j 5. IF LOCAL HEALTH CODES PERMIT THEUSE OF RERUN, make sure the mix rerun isstored in a sanitized, covered, NSF approvedstainless steel rerun container and used thefollowing day. DO NOT prime the machine withrerun. When using rerun, skim off the foam anddiscard; then mix the rerun with fresh mix in aratio of 50/50 during the day's operation.

j 6. On a designated day of the week, run the mix aslow as feasible and discard it after closing. Thiswill break the rerun cycle and reduce thepossibility of high bacteria and coliform counts.

j 7. Properly prepare the cleaning and sanitizingsolutions. Read and follow the label directionscarefully. Too strong of a solution may damagethe parts and too weak of a solution will not doan adequate job of cleaning or sanitizing.

j 8. The temperature of the mix in the mix hopperand walk-in cooler should be below 40_F.(4.4_C.).

Regular Maintenance Checks

j 1. Rotate the scraper blades to allow both sides ofthe knife edge to wear evenly. This willcontribute to self-sharpening and help maintainfast, efficient freezing.

j 2. Replace scraper blades that are bent,damaged, or worn smaller than 15/16”. Inspectthe condition of blades on a daily basis.

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

j 4. Dispose of o-rings and seals that are worn, torn,or fit too loosely, and replace with new ones.Inspect all rubber parts daily.

j 5. Check the rear shell bearing for signs of wear(excessive mix leakage in rear drip pan) and becertain it is properly cleaned. Inspect the rearshell bearing monthly.

j 6. Using a screwdriver and cloth towel, keep thefemale drive socket and the rear shell bearingfree of lubricant and mix deposits.

j 7. Follow all lubricating procedures as outlined inthe Operator Manual.


j 8. On air-cooled units, check the condenser filterfor an accumulation of dirt and lint. Dirtycondensers will reduce the efficiency andcapacity of the machine. The condensersshould be cleaned monthly. Remove the hoodto gain access to the condensers. Use a softbrush to clean between the fins of thecondenser. Never use screwdrivers or othermetal probes to clean between the fins.

CAUTION: Always disconnectelectrical power prior to cleaning thecondenser. Failure to follow thisinstruction may result in electrocution.

j 9. On water cooled units, check the water lines forkinks or leaks. Kinks can occur when themachine is moved back and forth for cleaning ormaintenance purposes. Deteriorated orcracked water lines should be replaced only byan authorized Taylor service technician.

j10. Inspect the drive shaft for wear and damage ona monthly basis.
