To the Operator

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 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.

Softecht Control Machines

Note: If your machine is not equipped with Softecht controls, please use the instructions on page 10.

Power Switch

When placed in the ON position, the power switch allows Softecht control panel operation.

MIX REF

When the MIX REF key is pressed, the light comes on indicating the mix hopper refrigeration system is operating. MIX REF is controlled by the left side of the freezer as viewed from the operator end. The MIX REF function cannot be cancelled unless the AUTO or

STANDBY modes are cancelled first.

STANDBY Key

The Separate Hopper Refrigeration System (SHR) and the Cylinder Temperature Retention System

(CTR) are standard features on Softecht machines.

The SHR incorporates the use of a separate small refrigeration system. This maintains the mix in the hopper below 40_(4.4_C) to assure bacteria control.

The CTR works with the SHR to maintain a good quality product. During long “No Sale” periods, it is necessary to warm the product in the freezing cylinder to approximately 35_F to 40_F (1.7_C to 4.4_C) to prevent overbeating and product breakdown.

To activate the SHR and CTR, press the STANDBY key. Place the end of the air tube without the hole into the mix inlet hole.

When the STANDBY key is pressed, the light comes on, indicating the CTR (Cylinder Temperature

Retention System) has been activated. In the

STANDBY mode, the WASH and AUTO functions are automatically cancelled. The MIX REF function is automatically locked in to maintain the mix in the hopper.

To resume normal operation, press the AUTO key.

When the unit cycles off, the product in the freezing cylinder will be at serving viscosity. At this time, place the orifice end of the air tube into the mix inlet hole.

Install the air orifice.

WASH Key

When the WASH key is pressed, the light comes on.

This indicates beater motor operation. The STANDBY or AUTO modes must be cancelled first to activate the

WASH mode.

AUTO Key

When the AUTO key is pressed, the light comes on.

This indicates that the main refrigeration system has been activated. In the AUTO mode, the WASH or

STANDBY functions are automatically cancelled. The

MIX REF function is automatically locked in to maintain the temperature of the mix in the mix hopper.

Note: An indicating light and an audible tone will sound whenever a mode of operation has been pressed. To cancel any function, press the key again.

The light and mode of operation will shut off.

Indicator Light - MIX LOW

Located on the front of the machine is a mix level indicating light. 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. Always maintain at least 3” (76 mm) of mix in the hopper. If you neglect to add mix, a freeze-up may occur. This will cause eventual damage to the beater, blades, drive shaft, and freezer door.

Reset Button

The reset button is located on the front of the unit. The reset protects the beater motor from an overload condition. If an overload occurs, the reset mechanism will trip. To properly reset the freezer, press the AUTO key to cancel the cycle. Turn the power switch to the

OFF position. Press the reset button firmly.

Warning: Do not use metal objects to press the reset button. Failure to comply may result in severe personal injury or death.

Turn the power switch to the ON position. Press the

WASH key and observe the freezer’s performance.

Open the side access panel. Make sure the beater motor is turning the drive shaft in a clockwise direction

(from the operator end) without binding.


8

Model 161

If the beater motor is turning properly, press the WASH key to cancel the cycle. Press the AUTO key on both sides of the unit to resume normal operation. If the freezer shuts down again, contact a service technician.

Air Tube

The air tube serves two purposes. One end of the tube has an orifice (hole) and the other end does not.

1. After priming the machine, place the orifice end of the air tube into the mix inlet hole. Every time the draw handle is raised, new mix and air from the hopper will flow down into the freezing cylinder. This will keep the freezing cylinder properly loaded and will maintain overrun.

2. During long “No Sale” periods, remove the air tube. Replace the air tube with the (end without hole), into the mix inlet hole. This will prevent any mix from entering the freezing cylinder.

The air tube maintains overrun and allows enough mix to enter the freezing cylinder after a draw.

Non--Softecht Control Machines

Note: If your machine is equipped with the Softecht controls, please use the instructions on page 7.

Push-Button Switch

If an overload condition occurs, the freezer will automatically stop operating. To properly reset the freezer, place the toggle switch in the OFF position.

Wait two or three minutes; then press the push-button switch. Place the power switch in the WASH position and observe the freezer’s performance; place the power switch in the AUTO position.

Note: If the freezer is unplugged from the wall receptacle, it will be necessary to press the push-button switch for the freezer to operate once power is re-established.

Power Switch

The center position is OFF. The left position is WASH which activates the beater motor only. The right position is AUTO, which activates the beater motor and the refrigeration system.

Air Tube

The Model 161 is called upon to handle a large variety of products (i.e., soft serve, yogurts, Italian ices, sherbets, etc.). Thus, the consistency of the mix you use will vary. The air tube meters a combination of mix and air into the freezing cylinder. If not enough mix enters the freezing cylinder, a freeze-up may occur, which will cause eventual damage to the beater.

Depending upon the product being run, you may wish to contact your local authorized Taylor Distributor to make a slight adjustment in the air tube.

Figure 2

Note: During AUTO operation, the orifice end of the tube should be inserted in the hole in the hopper.

Taylor Quality Control

The Model 161 uses a solid state control called the

Watt Control. The purpose of this solid state control is to sense the viscosity (thickness) of the product in the freezing cylinder. With the power switch in the AUTO position, the Watt Control will automatically keep the mix in the freezing cylinder at the proper viscosity and ready for serving.

Indicator Light -- Mix Low

A mix level indicating light is located at the front of the machine. When the light is on, it indicates that the mix hopper has a low supply of mix and should be refilled as soon as possible. Always maintain at least 2” (51 mm) of mix in the hopper. If you neglect to add mix, a freeze-up may occur. This will cause eventual damage to the beater assembly and to the freezer door.

Model 161

Section 6 Operating Procedures

The Model 161 is a soft serve counter model with a three spout door. Two individual flavors are available from the end spouts, and an equal combination of both is dispensed through the center spout to create a twist effect. It has a 1.5 quart (1.4 liter) capacity freezing cylinder. The mix flows by gravity from the hopper to the freezing cylinder through an air tube.

Duplicate the procedures where they apply for the second freezing cylinder.

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.

These opening procedures will show you how to assemble these parts into the machine, sanitize them, and prime the machine with fresh mix in preparation to serve your first portion.

Assembly

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

Step 1

To install the beater assembly, slide the small, thick o-ring into the groove on the drive shaft of the beater assembly. Apply an even coat of lubricant to the o-ring and the shaft. DO NOT lubricate the hex end.

Figure 4

Step 2

Insert the beater assembly through the rear shell bearing at the back of the freezing cylinder and engage the hex end firmly into the female socket. When properly seated, the beater will not protrude beyond the front of the freezing cylinder.

Figure 3

If you are disassembling the machine for the first time or need information to get to the starting point in our instructions, turn to page 18, “Disassembly”, and start there.

Disassembly

MAKE SURE THE POWER SWITCH IS IN

THE “OFF” POSITION. Failure to follow this instruction may result in severe personal injury to fingers or hands from hazardous moving parts.

Step 1

Remove the handscrews and the freezer door.

Remove the beater assemblies from the freezing cylinders and take these parts to the sink for cleaning.

Step 2

Remove the front drip tray and the splash shield from the machine. Take them to the sink for cleaning.

Brush Cleaning

Step 1

Prepare a sink with an approved cleaning solution

(example: Kay-5r). USE WARM WATER AND

FOLLOW THE MANUFACTURER’S SPECIFI-

CATIONS.

IMPORTANT: Follow label directions, as too

STRONG of a solution can cause parts damage, while too MILD of a solution will not provide adequate cleaning.) Make sure all brushes provided with the machine are available for brush cleaning.

Step 2

Remove the o-rings from the drive shafts of the beater assemblies.

Note: To remove the 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 rings without falling into the open grooves.

Step 3

From the freezer door, remove design caps, pivot pins, draw handles, and draw valves. Remove all o-rings.

Step 4

Remove the large o-rings, front bearings, and guide bearings from the back of the freezer door.

Step 5

Return to the machine with a small amount of cleaning solution. With the black bristle brush, brush clean the rear shell bearings at the back of the freezing cylinders.

Step 6

Remove the rear drip pan from the side panel and take it to the sink for cleaning.

Note: If the drip pan is filled with an excessive amount of mix, this is an indication that the drive shaft o-ring of the beater assembly should be replaced or properly lubricated.

Step 7

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

Step 8

Wipe clean all exterior surfaces of the machine.

Section 7 Important: Operator Checklist

During Cleaning and Sanitizing

ALWAYS FOLLOW LOCAL HEALTH CODES.

Cleaning and sanitizing schedules are governed by your State or local regulatory agencies and must be followed accordingly. The following check points should be stressed during the cleaning and sanitizing operations.

WE RECOMMEND DAILY CLEANING AND

SANITIZING.

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 smaller, 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 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 is used the following day. DO

NOT prime the machine with rerun. When using rerun, skim off the foam and discard. Mix 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.).

Regular Maintenance Checks

j

1. Check the rear shell bearing for signs of wear

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

j

2. 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.

j

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

j

4. Follow all lubricating procedures as outlined in

“Assembly”.

j

5. If your machine is air cooled, check the condenser for an accumulation of dirt and lint.

A dirty condenser 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.

CAUTION: Always disconnect electrical power prior to cleaning the con-

denser. Failure to follow this instruction may result in electrocution.

Model 161

19

Important: Operator Checklist

j

6. If your machine is equipped with an auxiliary refrigeration system, check the auxiliary condenser for accumulation of dirt and lint. A dirty condenser will reduce the refrigeration capacity of the mix hopper. Condensers must be cleaned monthly with a soft brush. Never use screwdrivers or other metal probes to clean between the fins. Failure to comply may result in electrocution.

j

7. If your machine is water cooled, 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

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, and then add a liberal amount of permanent type auto anti-freeze.

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 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.
