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
WASH Key
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_Fto40_F(1.7_Cto4.4_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.
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.
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.
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 161Important: To the Operator
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.
Figure 1
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.
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.
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 T aylor Distributor to
make a slight adjustment in the air tube.
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.

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.

Prepare one gallon (3.8 liters) of an approved cleaning
solution (example: Kay-5r). USE WARM WATER
AND FOLLOW THE MANUFACTURER’S SPECIFICATIONS.
Step 2
Pour the one gallon (3.8 liters) of cleaning solution into
the mix hopper and allow it to flow into the freezing
cylinder.
ALWAYS FOLLOW LOCAL HEALTH CODES.
Rinsing
Step 1
Pour one gallon (3.8 liters) of cool, clean water into the
mix hopper. With the brushes provided, scrub the mix
hopper, and the mix inlet hole.
Note: Non--Softecht machines: Scrub the mix
level float stem.
Step 2
With a pail beneath the door spouts, press the WASH
key and open the draw valves.
Note: Non--Softecht machines: Place the power
switch in the WASH position.
Step 3
While the solution is flowing into the freezing cylinder,
brush-clean the mix hopper, mix level float stem and
mix inlet hole.
Step 4
Press the WASH key. This will cause the cleaning
solution in the freezing cylinder to agitate.
Note: Non--Softecht machines: Place the power
switch in the WASH position.
Step 5
Place an empty pail beneath the door spouts and raise
the draw valve. Draw off all the cleaning solution.
When the solution stops flowing from the door spouts,
close the draw valves. Press the WASH key to cancel.
Note: Non--Softecht machines: Place the power
switch in the OFF position to cancel.
Repeat Steps 1 through 5 for the other side of the
machine.
Model 161 Operating Procedures

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.
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.
Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution
(example: Kay-5r). USE WARM WATER AND
FOLLOW THE MANUFACTURER’S SPECIFICATIONS.
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.
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.

Model 161Operating Procedures
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.
T roubleshooting 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 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. 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 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 condenser. Failure to follow this instruction may
result in electrocution.
Model 161 Important: Operator Checklist
19
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 wa-
ter 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.
