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.
Figure 2
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.
Temperature Control
The Models 150 and 152 use a temperature control to
monitor the product in the freezing cylinder. Turning
the adjusting knob clockwise will decrease the
product temperature. Turning the adjusting knob
counterclockwise will increase the temperature.
Each quarter of a turn will vary the temperature
approximately two degrees. DO NOT set the
temperature control colder than 18_F (-8_C). Should
you set the temperature colder than 18_F (-8_C),
premature failure of the belts and of the beater motor
may occur.
Note: During “AUTO” operation, the orifice end of the
tube should be inserted in the hole in the hopper.
Taylor Quality Control
The Models 162 and 168 use a solid state control
called the T.Q.C. The purposeof 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 T.Q.C. will automatically keep the
mix in the freezing cylinder at the proper viscosity and
ready for serving.
The Models 150 and 152 are available with the T.Q.C.
as an option.
Air Tube
The models 150, 152, 162 and 168 are 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.
Models 150, 152, 162, 168Important: To the Operator
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” (5.1
cm) 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.
11
Mix Refrigeration Switch
The mix refrigeration switch is located under the
control channel and is used for several purposes:
1.For the unit to operate in the “AUTO” mode, the
mix refrigeration switch must be “ON”.
2.For the separate hopper refrigeration system to
operate, the mix refrigeration switch must be in
the “ON” or the “STANDBY” position.
3.For the cylinder temperature retention system
to operate, the power switch must be in the
“AUTO” position and the mix refrigeration
switch must be in the “STANDBY” position.
Cylinder Temperature Retention
(CTR)
To maintain a good quality product during long “No
Sale” periods, it will be necessary to warm the product
in the freezing cylinder to approximately 35_ to 40_F
(1.7_ to 4.4_C). This will prevent overbeating and
product breakdown. The CTR is used in conjunction
with the SHR to insure that the mix in the freezing
cylinder is refrigerated during the “STANDBY” mode of
operation.
To operate the “STANDBY” mode of operation:
Place the power switch in the “AUTO” position and the
mix refrigeration switch in the “STANDBY” position.
With sanitized hands, remove the air tube. Turn it over
and place the end without the hole into the mix inlet
hole.
To resume normal operation:
Separate Hopper Refrigeration
(SHR)
This feature incorporates the use of a separate small
refrigeration system to chill (on a limited basis) and to
maintain the mix in the hopper to under 40_F(4.4_C)
and assures bacterial control. To activate this system,
place the power switch in the “AUTO” position and the
mix refrigeration switch in the “AUTO” position. To operate this system in the “STANDBY” mode, place the
power switch in the “AUTO” position and the mix refrigeration switch in the “STANDBY” position.
Leave the power switch in the “AUTO” position and
place the mix refrigeration switch in the “AUTO”
position. When the unit cycles off, the product in the
freezing cylinder will be the correct viscosity. With
sanitized hands, remove the air tube. Turn it over and
place the end with the hole into the mix inlet hole.
Syrup Rail
These units are available with an optional syrup rail to
store cold toppings for sundaes.

Section 6Operating Procedures
The Model 150 has been selected to illustrate the
pictured step-by-step operating procedures. All
models in this manual are similar. They each have 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.
The Model 150 is a console model with a single spout
door.
The Model 152 is a counter model with a single spout
door.
The Model 162 is a counter model and the Model 168
is a console model. Both have three spout doors. 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.
For the Model 162 and 168, 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 freezer, sanitize them,
and prime the freezer with fresh mix in preparation to
serve your first portion.

Brush Cleaning
Step 1
Prepare a sink with an approved cleaning solution.
USE WARM WAT ER 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
freezer are available for brush cleaning.
Step 4
Remove the large o-ring(s), front bearing(s), and guide
bearing(s) from the back of the freezer door.
Step 5
Return to the freezer with a small amount of cleaning
solution. With the black bristle brush, brush clean the
rear shell bearing(s) at the back of the freezing
cylinder(s).
Step 2
Remove the o-ring(s) from the drive shaft(s) of the
beater assembly(ies).
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

Section 7Important: Operator Checklist
During Cleaning and Sanitizing
ALWAYS FOLLOW LOCAL HEALTH CODES.
Cleaning and sanitizing schedules are governed
by federal, state, or local regulatory agencies,
and must be followed accordingly. If the unit
has a “Standby mode”, it must not be used in
lieu of proper cleaning and sanitizing
procedures and frequencies set forth by the
ruling health authority. The following check
points should be stressed during the cleaning
and sanitizing operations.
CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.
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 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
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. Failure to comply may result
in electrocution.
Note: For machines equipped with an air filter,
it will be necessary to vacuum clean the filters
on a monthly schedule.
j 6. If your machine is equipped with an auxiliary
refrigeration system, check the 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.
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.
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
cleaningormaintenancepurposes.
Deteriorated or cracked water lines should be
replacedonlybyanauthorizedTaylor
mechanic.
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
canbeprotectedbywrappingthemwith
moisture-proof paper. All parts should be thoroughly
cleaned of dried mix or lubrication accumulations
which attract mice and other vermin.
