Section 1 To the InstallerThis machine is designed for indoor use only.
DO NOT install the machine in an area whereawater jet could beused to clean or rinse themachine.Failure to follow this instruction may result in seriouselectrical shock.
Water Connections(Water Cooled Units Only)
An adequate cold water supply must be provided witha hand shut-off valve. On the underside rear of thebase pan, two 3/8” I.P.S. (for single-head units) or two1/2” I.P.S. (for double-head units) water connectionsfor inlet and outlet have been provided for easyhook-up. 1/2” inside diameter water lines should beconnected to the machine. (Flexible lines arerecommended, if local codes permit.) Depending onlocal water conditions, it may be advisable to install awater strainer to prevent foreign substances fromclogging the automatic water valve. There will be onlyone water “in” and one water “out” connection for bothsingle-head and double-head units. DO NOT install ahand shut-off valve on the water “out” line! Watershould always flow in this order: first, through theautomatic water valve; second, through thecondenser; and third, through the outlet fitting to anopen trap drain.
Air Cooled Units
The model 750 air cooled unit requires a minimum of6” (152 mm) of clearance on both sides and 0” in therear of the unit. Themodel 751, 754, 774 and 794unitsrequire 3” on all sides. This will allow for adequate airflow across the condenser(s). Failure to allowadequate clearance can reduce the refrigerationcapacity of the freezer and possibly cause permanentdamage to the compressor.

Power Switch
When placed in the ON position, the power switchallows SOFTECH control panel operation.
MIX LOW Indicator Light
Located on the front of the machine is a mix levelindicating light. When the light is flashing, it indicatesthat themix hopper has a low supply of mix and shouldbe refilled as soon as possible. Always maintain atleast 3” (7.6 cm) of mix in the hopper. If you neglect toadd mix, a freeze-up may occur. This will causeeventual damage to the beater, blades, drive shaft,and freezer door.
MIX REF Key
When the MIX REF key is pressed, the light comes onindicating the mix hopper refrigeration system isoperating. For the Models 754, 774, and 794 the MIXREF is controlled by the left side of the freezer asviewed from the operator end. The MIX REF functioncannot be cancelled unless the AUTO or STANDBYmodes are cancelled first.
STANDBY Key
The Separate Hopper Refrigeration System (SHR)and the Cylinder Temperature Retention System(CTR) are standard features on these machines. TheSHR incorporates the use of a separate smallrefrigeration system to maintain the mix in the hopperbelow 40_(4.4_C) to assure bacteria control. TheCTRworks with theSHR tomaintain agood quality product.During long “No Sale” periods, it is necessary to warmthe product in the freezing cylinder to approximately35_F to 40_F (1.7_C to 4.4_C) to prevent overbeatingand product breakdown.
To activate the SHR and CTR, press the STANDBYkey. Remove the air orifice and place the air tube (endwithout the hole) into the mix inlet hole.
When the STANDBY key is pressed, the light comeson, indicating the CTR (Cylinder TemperatureRetention System) has been activated. In theSTANDBY mode, the WASH and AUTO functions areautomatically cancelled. The MIX REF function isautomatically locked in to maintain the mix in thehopper.
To resume normal operation, press the AUTO key.When the unit cycles off, the product in the freezingcylinder will be at serving viscosity. At this time, placethe air tube (end with the hole) into the mix inlet holeand install the air orifice.
WASH Key
When the WASH key is pressed, the light comes on.This indicates beater motor operation. The STANDBYor AUTOmodes must be cancelled first to activate theWASH mode.
AUTO Key
When the AUTO key is pressed, the light comes on.This indicates that the main refrigeration system hasbeen activated. In the AUTO mode, the WASH orSTANDBY functions are automatically cancelled. TheMIX REF function is automatically locked in tomaintain the mix in the mix hopper.
Note: An indicating light and an audible tone willsound whenever a mode of operation has beenpressed. To cancel any function, press the key again.The light and mode of operation will shut off.

Reset Button
On counter models, the reset button is located on theside of the unit. On console models, the reset buttonis located in the service panel. The reset protects thebeatermotor fromanoverload condition. If anoverloadoccurs, the reset mechanismwill trip. To properly resetthe freezer, press the AUTO key to cancel the cycle.Turn the power switch to the OFF position. Press thereset button firmly.
Donot usemetal objects to press the resetbutton. Failure to follow this instruction mayresult in electrocution.
Turn the power switch to the ON position. Press theWASH key and observe the freezer’s performance.Open the side access panel. Make sure the beatermotor is turning the drive shaft in a clockwise direction(from the operator end) without binding.
If the beatermotor is turning properly, press theWASHkey to cancel the cycle. Press theAUTOkey to resumenormal operation. If the freezer shuts down again,contact a service technician. (For Models 754, 774,and 794 press the AUTO key on both sides of the unitto resume normal operation.)
Air Tube
The air tube serves two purposes. One end of the tubehas a hole and the other end does not.
Figure 1
1. After priming the machine, lubricate the o-ringson the air tube (the end with the hole) andplace it into the mix inlet hole. Every time the
draw handle is raised, new mix and air from thehopper will flow down into the freezing cylinder.This will keep the freezing cylinder properlyloaded and will maintain overrun.
2. During long “No Sale” periods, remove the airorifice. Lubricate the o-rings on the air tube (theend without the hole), and place it into themix inlet hole. This will prevent any mix fromentering the freezing cylinder.
The air orifice is used to meter a certain amountof air into the freezing cylinder. The air orificemaintains overrunandallows enoughmix to enterthe freezing cylinder after a draw.
Adjustable Draw Handle
These units feature an adjustable draw handle toprovide the best portion control. The draw handleshould be adjusted to provide a flow rate of 5 to 7-1/2oz. (148 to 222 ml) of product per 10 seconds. ToINCREASE the flow rate, turn the screwCOUNTERCLOCKWISE. Turn the screwCLOCKWISE to DECREASE the flow rate. During“Sanitizing” and “Rinsing”, the flow rate can beincreased by removing the pivot pin and placing therestrictive bar on the TOP. When drawing product,always place the restrictive bar on the bottom.
Figure 2
IMPORTANT:Once the draw rate is set, tighten thelock nut with a wrench.

Section 6 Operating Procedures
The Model 751 has been selected to illustrate thestep-by-step operating procedures for all modelscontained in this manual. These models, for allpractical purposes of operation, are the same.
Each unit stores mix in a hopper. The mix then flowsby gravity through an air tube down into the freezingcylinder. They all have 3.4 quart (3.2 liter) capacityfreezing cylinders. TheModels 750, 751, 754, and 774have 20 quart (18.9 liter) mix hoppers. The Model 794has 14 quart (13.2 liter) mix hoppers.
Duplicate the following procedures, where they apply,for the second freezing cylinder on Models 754, 774,and 794.
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.
These opening procedures will show you how toassemble these parts into the freezer, sanitize them,and prime the freezer with fresh mix in preparation toserve your 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 24, “Disassembly”, and startthere.
Prior to Set-Up (Model 774)
Step 1Remove the two stainless syrup jars with toppingpumps from the syrup rail. Check the water level in theheated syrup toppingwell. Make sure thewater is filledto the indicating mark on the bottom of the well. Theheated rail should have 32 oz. (946.2 ml) of water.
Step 2Place the heater switch in the ON position.
Note: This heating process will take approximately2-1/2 hours to reach temperature. The water level inthe topping wells must be checked at least once daily.
Step 3Prepareapail of anapproved100PPMsanitizing solu-tion (example: Kay-5r). USE WARM WATER ANDFOLLOW THE MANUFACTURER’S SPECIFI-CATIONS. Sanitize the topping pumps by placing theentire pump assembly in the pail of sanitizing solution.Pump the solution through the assembly to thoroughlysanitize the pump.
Step 4Remove the two topping pumps. Fill each stainlesssyrup jar with topping. Replace the topping pumps inthe syrup jars.

During Cleaning and Sanitizing
Cleaning and sanitizing schedules are governed byyour State or local regulatory agencies and must befollowed accordingly. The following check pointsshould be stressed during the cleaning and sanitizingoperations.
WE RECOMMEND DAILY CLEANING ANDSANITIZING.
ALWAYS FOLLOW LOCAL HEALTH CODES.
Troubleshooting Bacterial Count
j 1. Thoroughly clean and sanitize 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 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 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 stainless steelcontainer and used the following day. DO NOTprime the machine with rerun. When usingrerun, skim off the foam and discard. Mix thererunwith freshmix in a ratio of 50/50 during thedays operation.
j 6. On a designated day of theweek, run themix 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 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. Replace scraper blades that are nicked ordamaged. Before installing the beaterassembly, be certain that scraper blades areproperly attached to the helix.
j 2. Check the rear shell bearing for signs of wear(excessive mix leakage in rear drip pan) and becertain it is properly cleaned.
j 3. Using a screwdriver and cloth towel, keep therear shell bearing and the female hex drivesocket clean and free of lubricant and mixdeposits.
j 4. Dispose of o-rings and seals if they are worn,torn, or fit too loosely, and replace with newones.
j 5. Follow all lubricating procedures as outlined in“Assembly”.
j 6. If your machine is air cooled, check thecondensers for accumulation of dirt and lint.Dirty condensers will reduce the efficiency andcapacity of themachine. Condensers should becleaned monthly with a soft brush. Never usescrewdrivers or other metal probes to cleanbetween the fins.
Caution: Always disconnectelectrical power prior to cleaning thecondenser. Failure to follow this instructionmay result in electrocution.
26 Models 750, 751, 754, 774, 794Important: Operator Checklist
j 7. If your machine is equipped with an auxiliaryrefrigeration system, check the auxiliarycondenser for accumulation of dirt and lint. Dirtycondensers will reduce the refrigerationcapacity of the mix hopper. Condensers mustbe cleanedmonthlywith a soft brush. Neverusescrewdrivers or other metal probes to cleanbetween the fins. Failure to follow thisinstruction may result in electrocution.
Caution: Always disconnectelectrical power prior to cleaning thecondenser. Failure to follow this instructionmay result in electrocution.
j 8. If yourmachine iswater cooled, check thewaterlines for kinks or leaks. Kinks can occur whenthe machine is moved back and forth forcleaning or maintenance purposes.Deteriorated or cracked water lines should bereplaced only by an authorized Taylordistributor.
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, and then add aliberal amount of permanent type auto anti-freeze.This is extremely important. Failure to follow thisproceduremay cause severe and costlydamage to therefrigeration system.
Your local Taylor Distributor can perform this winterstorage service for you.
Wrap detachable parts of the freezer such as beater,blades, drive shaft, and freezer door, and place theminaprotecteddry place. Rubber trimparts andgasketscan be protected by wrapping them withmoisture-proof paper. All parts should be thoroughlycleaned of dried mix or lubrication which attract miceand other vermin.
