If the supply cord is damaged, it must bereplaced by the manufacturer, its serviceagent, or similarly qualified person, in order toavoid a hazard.

Check OutOnce the unit is installed, it is advisable to check thefollowing controls and mechanical operations of thefreezer and make any necessary adjustments. Ifapplicable, repeat these checks for the secondfreezing cylinder on double head units.

Controls

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

Figure 1

If the freezer is water cooled, the automatic watervalvewill begin to open and cold water will flow into thecondenser. This will remove heat from the refrigerant.As thewater flows into the open trap drain, it should bewarm to the touch. Place the control switch in the“OFF” position.

Beater Rotation

Beater rotation must be clockwise as viewedlooking into the freezing cylinder.

Note: The following procedures must beperformed by an authorized Taylor servicetechnician.

To correct rotation on a three-phase unit, interchangeany two incoming power supply lines at the freezermain terminal block only.

To correct rotation on a single-phase unit, exchangeleads inside the beater motor. (Follow the diagramprinted on the motor.)

Electrical connections are made directly to theterminal block provided in themain control box locatedbehind the upper left side panel for theModel 702, andbehind the service panel for the Model 741 and 772.

Refrigerant

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

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

NEVER fill any refrigerant cylinder completely withliquid. Filling the cylinder to approximately 80% willallow for normal expansion.

Use only R404A refrigerant that conforms tothe AHRI standard 700 specification. The use of anyother refrigerant may expose users and operators tounexpected safety hazards.

Refrigerant liquid sprayed onto the skin maycause serious damage to tissue. Keep eyes and skinprotected. If refrigerant burns should occur, flushimmediately with cold water. If burns are severe, applyice packs and contact a physician immediately.

Taylor reminds technicians to be cautious ofgovernment laws regarding refrigerant recovery,recycling, and reclaiming systems. If you have anyquestions regarding these laws, please contact thefactory Service Department.

WARNING: R404A refrigerant used inconjunction with polyolester oils is extremely moistureabsorbent. When opening a refrigeration system, themaximum time the system is openmust not exceed 15minutes. Cap all open tubing to prevent humid air orwater from being absorbed by the oil.

Compressor Warranty Disclaimer

The refrigeration compressor(s) on this unit arewarranted for the term stated in the Limited Warrantysection in this manual. However, due to the MontrealProtocol and the U.S. Clean Air Act Amendments of1990, many new refrigerants are being tested anddeveloped, thus seeking their way into the serviceindustry. Some of these new refrigerants are beingadvertised as drop- in replacements for numerousapplications. It should be noted that in the event ofordinary service to this unit’s refrigeration system,only the refrigerant specified on the affixed datalabel should be used. The unauthorized use ofalternate refrigerants will void your Taylor compressorwarranty. It is the unit owner’s responsibility to makethis fact known to any technician he employs.

It should also be noted that Taylor does not warrant therefrigerant used in its equipment. For example, if therefrigerant is lost during the course of ordinary serviceto this machine, Taylor has no obligation to eithersupply or provide its replacement either at billable orunbillable terms. Taylor does have the obligation torecommend a suitable replacement if the originalrefrigerant is banned, obsoleted, or no longer availableduring the five year warranty of the compressor.

The Taylor Company will continue to monitor theindustry and test new alternates as they are beingdeveloped. Should a new alternate prove, through ourtesting, that it would be accepted as a drop-inreplacement, then the above disclaimer wouldbecome null and void.

Thermistor ControlTheviscosity (thickness) of theproduct is controlled bya temperature sensing device called the thermistor. Toachieve a thicker product, turn the control clockwise,and turn the control counterclockwise to achieve athinner product. Allow the refrigeration system to cycleon and off 2 or 3 times before an accurate consistencycan be evaluated.

Separate Hopper RefrigerationSystem (SHR)

“Standby”The Separate Hopper Refrigeration System (SHR)and the Cylinder Temperature Retention System(CTR) are standard features. This feature is referredto as “STANDBY”. The SHR incorporates the use of aseparate small refrigeration system to maintain themix temperature in the hopper to below 40_F. (4.4_C.)This assures bacteria control. The CTRworks with theSHR to maintain a good quality product. During long“No Sale” periods, it becomes necessary to warm theproduct in the freezing cylinder to approximately 35_F.to 40_F. (1.7_C. to 4.4_C.) to prevent overbeating andproduct breakdown.

ALWAYS FOLLOW LOCAL HEALTH CODES.

Cleaning and sanitizing schedules are governedby federal, state, or local regulatory agencies, andmust be followed accordingly. If the unit has a“Standby mode”, it must not be used in lieu ofproper cleaning and sanitizing procedures andfrequencies set forth by the ruling healthauthority.

CLEANING AND SANITIZING MUST BEPERFORMED DAILY.

IMPORTANT: Make sure your hands aresanitized before performing these instructions:

To activate SHR and CTR, place the air tube (endwithout the hole) into the mix inlet hole.

Place the control switch in the “AUTO” position, andturn the STANDBY switch to the “ON” position. Theunit will operate as a refrigerator for product in thehopper and freezing cylinder.

To remove the unit from the “STANDBY” mode, placethe control switch in the “AUTO” position, and turn thestandby switch to the “OFF” position. The unit willresume the normal operating mode.

When the unit cycles off, remove the hopper cover,and place the feed tube in its original position.

Replace the hopper cover.

15Models 702/741/772 Operating Procedures

Section 6 Operating Procedures

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

They all store 20 quarts (18.9 liters) of mix in thehopper. The mix then flows by gravity through a mixfeed tube down into the freezing cylinder.

Locate your model number below to determine thecharacteristics of your freezer:

702: (1) 4 quart (3.8 liter) freezing cylinder.741: (1) 7 quart (6.6 liter) freezing cylinder.772: (2) 7 quart (6.6 liter) freezing cylinders.We begin our instructions at the point where we enterthe store in the morning and find the partsdisassembled and laid out to air dry from the previousnight’s cleaning.The following procedures will show you how toassemble the parts into the freezer, sanitize them, andprime the freezer with freshmix in preparation to serveyour first portion.

If you are disassembling the machine for the first timeor need information to get to this starting point in ourinstructions, turn to page 21, “Disassembly” and startthere.

Assembly

MAKE SURE THE CONTROL SWITCH ISIN THE “OFF” POSITION TO ELIMINATE THECHANCE OF MOVING PARTS.

Note: When lubricating parts, use an approved foodgrade lubricant (example: Taylor Lube).

Step 1Lubricate the groove and shaft portion that comes incontact with thebearingon thebeater drive shaft. Slidethe seal over the shaft and groove until it fits into place.DONOT lubricate thehex endof thedriveshaft. Fill theinside portion of the seal with 1/4” more lubricant andevenly lubricate the flat side of the seal that comes incontact with the bearing.

Figure 5

Insert the drive shaft through the rear shell bearing inthe freezing cylinder and engage the hex end firmlyinto the gear box coupling.

Step 2Before installing the beater assembly, check thescraper blades for any signs of wear or damage. If ascraper blade is nicked or worn, replace both blades.

Check the scraper blade clips to make sure they arenot bent and the slot is even for the entire length of theclip. Replace any damaged clips.

Figure 7

If the blades and clips are in good condition, place therear scraper blade over the rear holding pin on thebeater, knife edge to the outside.

Note: To prevent costly damage, the hole in thescraper blade must fit securely over the pin.

Holding the rear blade on the beater, slide theassembly halfway into the freezing cylinder. Install thefront scraper blade over the front holding pin. Slide thebeater assembly the rest of the way into the freezingcylinder.

Figure 8

Make sure the beater assembly is in position over thedrive shaft. Turn the beater slightly to be certain thatthe beater is properly seated. When in position, the

beater will not protrude beyond the front of the freezingcylinder.

Step 3Before assembling the freezer door, check thefollowing for any nicks, cracks, or signs of wear:front bearing, door gasket, draw valve, o- rings, and allsides of the door assembly, including the inside of thedraw valve bore. Replace any damaged parts.

Step 4Slide the twoo-rings into thegrooves on thedrawvalveand lubricate them with Taylor Lube.

Figure 9

Lubricate the inside of the freezer door spout, top andbottom. Insert the drawvalve into the freezer door fromthe top. It will be necessary to rotate the draw valve tothe right when assembling the door to the freezer.

Figure 10

Step 5Place the freezer door gasket into the groove on theback of the freezer door. Slide the front bearing overthe baffle rod so the flanged edge is against the door.Do not lubricate the gasket or bearing.

Sanitizing

Step 1Prepare a pail of an approved 100 PPM sanitizingsolution (examples: 2- 1/2 gal. [9.5 liters] of Kay- 5Ror 2 gal. [7.6 liters] of Stera- SheenR). USE WARMWATER AND FOLLOW THE MANUFACTURER’SSPECIFICATIONS.

Step 2Pour the sanitizing solution into the hopper and allowit to flow into the freezing cylinder.

Figure 16

Step 3While the solution is flowing into the freezing cylinder,brush clean thehopper.While cleaning themixhopper,take particular care in brushing the mix level sensingprobe on the rear wall of the hopper, the mix inlet hole,the hopper gasket, and the mix feed tube.

Figure 17

Step 4Place the control switch in the “WASH” position. Thiswill cause the sanitizing solution in the freezingcylinder to agitate. Allow the solution to agitate for fiveminutes.

Figure 18

Step 5Place an empty pail beneath the door spout and raisethe draw arm. Draw off all the sanitizing solution.

Figure 19

Step 6When the sanitizer stops flowing from the door spout,lower the draw arm and place the control switch in the“OFF” position.

IMPORTANT! The unit must NOT be placed in AUTOuntil all sanitizing solution has been removed from thefreezing cylinder and proper priming procedures havebeen completed. Failure to follow this instruction mayresult in damage to the freezing cylinder.

Step 5Place an empty pail beneath the door spout and raisethe draw arm. Draw off all the cleaning solution. Whenthe solution stops flowing from the door spout, lowerthe draw arm and place the control switch in the “OFF”position.

Repeat Steps 1 through 5 for the second freezingcylinder on the Model 772.

DisassemblyNote: Failure to remove parts, brush clean and thenair dry these parts, will result in damage to the relatedparts.

Step 1

BE SURE THE CONTROL SWITCH IS INTHE “OFF” POSITION TO ELIMINATE THECHANCE OF MOVING PARTS.

Step 2Remove the handscrews, the freezer door, the gasket,the front bearing, the beater, the scraper blade(s), andthe drive shaft from the freezing cylinder. Take theseparts to the sink for cleaning.

Step 3Remove the rear drip pan from the front panel.

Note: If the drip pan is filled with an excessive amountof mix, it is an indication that the drive shaft seal shouldbe replaced or was improperly lubricated.


Step 4Remove the front drip tray and the splash shield.

Brush CleaningStep 1Prepare a sink with an approved cleaning solution (ex-amples: Kay-5R or Stera- SheenR). USE WARMWATER AND FOLLOW THE MANUFACTURER’SSPECIFICATIONS

If an approved cleaner other than Kay-5R or Stera-SheenR is used, dilute it according to the label instruc-tions. IMPORTANT: Follow the label directions. TooSTRONG of a solution can cause parts damage. TooMILD of a solution will not provide adequate cleaning.

Make sure all brushes provided with the freezer areavailable for brush cleaning.

Step 2Remove the seal(s) from the drive shaft(s).

Step 3From 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, usea single service towel tograsp theo-ring. Apply pressure in an upwarddirectionuntil the o-ring pops out of its groove. With the otherhand, push the top of the o-ring forward. It will roll outof the groove and can be easily removed. If there ismore than one o-ring to be removed, always removethe rear o-ring first. This will allow the o-ring to slideover the forward rings without falling into the opengrooves.

Step 4Thoroughly brush clean all disassembled parts in thecleaning solution,making sure all lubricant andmix filmis removed. Take particular care to brush clean thedraw valve core in the freezer door(s). Place all thecleaned parts on a clean dry surface to air dryovernight.

Step 5Return to the freezer with a small amount of cleaningsolution. With the black bristle brush, brush clean therear shell bearing(s) at the back of the freezingcylinder(s).

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.

Troubleshooting Bacterial Countj 1. Thoroughly clean and sanitize the machine

regularly, 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 inlethole which extends from the mix hopper downto the rear of the freezing cylinder.

j 4. Use the black bristle brush to thoroughly cleanthe rear shell bearing located at the rear of thefreezing cylinder. Be sure there is 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 container and is 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 theweek, run themix aslow as feasible and discard 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 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 scraper blades to allow both sides of theknife edge to wear evenly. This will contribute toself-sharpening and help maintain fast, efficientfreezing.

j 2. Replace scraper blades that are nicked,damaged or worn.

j 3. Before installing the beater, be certain thatscraper blades are properly attached over thepins.

j 4. Check the rear shell bearing for signs of wear(excessive mix leakage in rear drip pan) and becertain it is properly cleaned.

j 5. Using a screwdriver and cloth towel, keep therear shell bearing and the female hex drivesocket clean and free of lubricant and mixdeposits.

23Models 702/741/772 Important: Operator Checklist

080324

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

j 7. Follow all lubricating procedures as outlined in“Assembly”.

j 8. Check the condensers for accumulation of dirtand lint. Dirty condensers will reduce theefficiency and capacity of the machine.Condensers should be cleanedmonthly with asoft brush. Never use screwdrivers or othermetal probes to clean between the fins.Note: For machines equipped with an air filter,it will be necessary to vacuum clean the filterson a monthly schedule.

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

Winter StorageIf the placeof business is to be closedduring thewintermonths, it is important to protect the freezer byfollowing certain precautions, particularly if thebuilding is subject to freezing conditions.

Disconnect the freezer from the main power source toprevent possible electrical damage.

On water cooled freezers, disconnect the watersupply. Relieve pressure on the spring in the watervalve. Use air pressure on the outlet side to blow outany water remaining in the condenser. This isextremely important. Failure to follow this proceduremay cause severe and costly damage to therefrigeration system.

Your local Taylor Distributor can perform this servicefor you.

Wrap detachable parts of the freezer such as thebeater, blades, drive shaft, and freezer door. Placethese parts in a protected, dry place. Rubber trimpartsand gaskets can be protected by wrapping them withmoisture-proof paper. All parts should be thoroughlycleaned of dried mix or lubrication which attract miceand other vermin.
