Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided with
a hand shut- off valve. On the underside rear of the
base pan, two 3/8” I.P.S. water connections for inlet
and outlet have been provided for easy hook- up. 1/2”
inside diameter water lines should be connected to the
machine. (Flexible lines are recommended, if local
codes permit.) Depending on local water conditions, it
may be advisable to install a water strainer to prevent
foreign substances from clogging the automatic water
valve. There will be only one water “in” and one water
“out” connection. DO NOT install a hand shut- off valve
on the water “out” line! Water should always flow in this
order: first, through the automatic water valve; second,
through the condenser; and third, through the outlet
fitting to an opentrapdrain.
A back flow prevention device is required
on the incoming water connection side. Please
refer to the applicable National, State, and local codes
for determining the proper configuration.
Electrical Connections
Each unit requires one power supply for each data
label on the unit. Check the data label(s) on the freezer
for branch circuit overcurrent protection or fuse, circuit
ampacity, and other electrical specifications. Refer to
the wiring diagram provided inside of the electrical box
for proper power connections.
In the United States, this equipment is intended to be
installed in accordance with the National Electrical
Code (NEC), ANSI/NFPA 70- 1987. The purpose of
the NEC code is the practical safeguarding of persons
and property from hazards arising from the use of
electricity. This code contains provisions considered
necessary for safety. Compliance therewith and
proper maintenance will result in an installation
essentially free from hazard!
In all other areas of the world, equipment should be
installed in accordance with the existing local codes.
Please contact your local authorities.
FOLLOW YOUR LOCAL ELECTRICAL CODES!
CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!
This unit is provided with an equipotential
grounding lug that is to be properly attached to the rear
of the frame by the authorized installer. The installation
location is marked by the equipotential bonding
symbol (5021 of IEC 60417-1) on both the removable
panel and the equipment’s frame.
SStationary appliances which are not equipped
with a power cord and a plug or another device
to disconnect the appliance from the power
source must have an all-pole disconnecting
device with a contact gap of at least 3 mm
installed in the external installation.
SAppliances that are permanently connected to
fixed wiring and for which leakage currents
may exceed 10 mA, particularly when
disconnected or not used for long periods, or
during initial installation, shall have protective
devices such as a GFI, to protect against the
leakage of current, installed by the authorized
personnel to the local codes.
SSupply cords used with this unit shall be
oil-resistant, sheathed flexible cable not
lighter than ordinary polychloroprene or other
equivalent synthetic elastomer-sheathed cord
(Code designation 60245 IEC 57) installed
with the proper cord anchorage to relieve
conductors from strain, including twisting, at
the terminals and protect the insulation of the
conductors from abrasion.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service
agent, or similarly qualified person, in order to
avoid a hazard.

Electrical Hook- Up Installation
(60 Cycle, 1 Ph, Supplied With Cord and Plug)
This freezer is supplied with a 3- wire cord and
grounding type plug for connection to a single phase,
60 cycle, branch circuit supply. This unit must be
plugged into a properly grounded receptacle. The cord
and plug provided for 208/230/60/1, is 20A; therefore
the wall outlet must also be 20A. Check the data label,
located on the side panel, for electrical specifications.
Permanent wiring may be employed if required by local
codes. Instructions for conversion to permanent wiring
are as follows:
1. Be sure the freezer is electrically disconnected.
2. Remove the appropriate panel and locate the
small electrical box at the base of the freezer.
3. Remove the factory- installed cord and strain
relief bushing.
4. Route incoming permanent wiring through 7/8”
(22 mm) hole in base pan.
5. Connect two power supply leads. Attach ground
(earth) wire to the grounding lug inside the
electrical box.
6. Be sure the unit is properly grounded before
applying power.
Beater Rotation
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: The following procedures should be
performed by a trained service technician.
To correct rotation on a three- phase unit, interchange
any two incoming power supply lines at freezer main
terminal block only. To correct rotation on a
single- phase unit, change the leads inside the beater
motor. (Follow diagram printed on motor.)
Electrical connections are made directly to the
terminal block provided in the splice boxes which are
mounted mid- level on the frame channel on the sides
of the freezer.
Refrigerant
In consideration of our environment, Taylor
uses only earth friendly HFC refrigerants. The HFC
refrigerant used in this unit is R404A. This refrigerant
is generally considered non-toxic and non-flammable,
with an Ozone Depleting Potential (ODP) of zero (0).
However, any gas under pressure is potentially
hazardous and must be handled with caution.
NEVER fill any refrigerant cylinder completely with
liquid. Filling the cylinder to approximately 80% will
allow for normal expansion.
Use only R404A refrigerant that conforms to
the AHRI standard 700 specification. The use of any
other refrigerant may expose users and operators to
unexpected safety hazards.
Refrigerant liquid sprayed onto the skin may
cause serious damage to tissue. Keep eyes and skin
protected. If refrigerant burns should occur, flush
immediately with cold water. If burns are severe, apply
ice packs and contact a physician immediately.
Taylor reminds technicians to be cautious of
government laws regarding refrigerant recovery,
recycling, and reclaiming systems. If you have any
questions regarding these laws, please contact the
factory Service Department.
WARNING: R404A refrigerant used in
conjunction with polyolester oils is extremely moisture
absorbent. When opening a refrigeration system, the
maximum time the system is open must not exceed 15
minutes. Cap all open tubing to prevent humid air or
water from being absorbed by the oil.

Section 2 To the Operator
The Model 161 soft serve freezer has been carefully
engineered and manufactured to give you dependable
operation.
This unit, when properly operated and cared for, will
produce a consistent quality product. Like all
mechanical products, it will require cleaning and
maintenance. A minimum amount of care and
attention is necessary if the operating procedures
outlined in this manual are followed closely.
This Operator’s Manual should be read
before operating or performing any maintenance on
your equipment.
The Model 161 will NOT eventually compensate and
correct for any errors during the set- up or filling
operations. Thus, the initial assembly and priming
procedures are of extreme importance. It is strongly
recommended that personnel responsible for the
equipment’s operation, both assembly and
disassembly, go through these procedures together in
order to be properly trained and to make sure that no
misunderstandings exist.
In the event you should require technical assistance,
please contact your local authorized Taylor Distributor.
Note: Your Taylor warranty is valid only if the parts are
authorized Taylor parts, purchased from the local
authorized Taylor Distributor, and only if all required
service work is provided by an authorized Taylor
service technician. Taylor reserves the right to deny
warranty claims on units or parts if non- Taylor
approved parts or incorrect refrigerant were installed
in the unit, system modifications were performed
beyond factory recommendations, or it is determined
that the failure was caused by abuse, misuse, neglect,
or failure to follow all operating instructions. For full
details of your Taylor Warranty, please see the Limited
Warranty section in this manual.
If the crossed out wheeled bin symbol is
affixed to this product, it signifies that this product is
compliant with the EU Directive as well as other similar
legislation in effect after August 13, 2005. Therefore,
it must be collected separately after its use is
completed, and cannot be disposed as unsorted
municipal waste. The user is responsible for returning
the product to the appropriate collection facility, as
specified by your local code.
For additional information regarding applicable local
laws, please contact the municipal facility and/or local
distributor.
Compressor Warranty Disclaimer
The refrigeration compressor(s) on this unit are
warranted for the term stated in the Limited Warranty
section in this manual. 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 unit’s refrigeration system,
only the refrigerant specified on the affixed data
label should be used. The unauthorized use of
alternate refrigerants will void your Taylor compressor
warranty. It is the unit 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.

This unit is equipped with a STANDBY feature. If
product is not dispensed for long periods of time (i.e.;
early morning hours), the STANDBY feature can be
activated to maintain the hopper and freezing cylinder
product at safe temperatures and prevent product
breakdown. In the STANDBY mode, the WASH and
AUTO functions are automatically cancelled.
To use the Standby feature, perform the following
steps:
Note: Be sure your hands are clean and sanitized
before performing the following steps.
Step 1
Invert the mix feed tube so the end with the mix
delivery hole is positioned at the top. Install the end
without the mix delivery hole into the mix inlet hole in
the bottom of the hopper. This will prevent mix from
entering the freezing cylinder.
Feed Tube Position During Standby Operation:
Figure 5
Step 2
Make sure there is at least 3” (76 mm) of mix in the
hopper and that the level of mix is not above the mix
delivery hole on the side of the feed tube.
Note: The level of mix must be below the mix
delivery hole on the side of the feed tube. Failure
to follow this instruction may result in lower product
quality when normal operation is resumed.
Step 3
Press the STANDBY key. The light will illuminate,
indicating that the unit is operating as a refrigerator for
product in the hopper and freezing cylinder.
Step 4
To remove the unit from the STANDBY mode, press
the AUTO key. The STANDBY light will extinguish,
indicating the unit has resumed the normal operating
mode.
Step 5

WASH Key
When the WASH key is pressed, the light comes on.
This indicates beater motor operation. The STANDBY
or AUTO mode 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. Wait two or three minutes and then
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. 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 an authorized
service technician.
Feed Tube
The feed tube maintains overrun and allows enough
mix to enter the freezing cylinder after a draw. One end
of the tube has a mix delivery hole on the side and the
other end does not.
Figure 7
The feed tube serves two purposes.
1. Normal Operation: After priming the machine,
the end of the feed tube with the mix delivery hole
is placed in 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.
Feed Tube Position During Normal Operation:

2. Standby Operation: During long “No Sale”
periods, the feed tube is inverted. The end of the
feed tube without the mix delivery hole is placed
in the mix inlet hole to prevent mix from entering
the freezing cylinder.
Feed Tube Position During Standby Operation:
Figure 9
Note: Make sure the level of mix is below the mix
delivery hole in the side of the feed tube. Failure to
follow this instruction may result in lower product
quality when normal operation is resumed.

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 a feed 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.
Figure 10
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 20, “Disassembly”, and start
there.
Assembly
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).
Step 1
Lubricate the groove on the beater drive shaft. With the
opening of the cup seal facing away from the hex end,
slide the seal into the groove. Apply an even coat of
lubricant to the seal and the shaft. Do not
lubricate the hex end of the beater drive shaft.
Figure 11
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 12
Repeat Steps 1 through 2 for the other side of the
machine.

Step 3
Place the large o- rings into the grooves on the back of
the machine door and lubricate.
Figure 13
Step 4
Slide the front bearings over the baffle rods so the
flanged edge is against the door. Place the white
plastic guide bearings on the end of the baffle rods.
DO NOT lubricate the front bearings or the guide
bearings.
Figure 14
Step 5
Slide the slotted portion of the handscrews into the
slots in the freezer door.
Step 6
With both hands, hold the sides of the freezer door and
insert the baffle rods into the center of the beater
assemblies. The white guide bearings must fit
securely in the holes of the drive shafts.
Step 7
Finger- tighten the handscrews, making sure they are
tightened equally and that the door is snug. Do not
over- tighten the handscrews.
Figure 15
IMPORTANT! Handscrew and door damage can
result if the handscrews are over- tightened or if
one handscrew is tightened more than the other.
Step 8
Install the valve seal into the grooves on the center
draw valve and lubricate. This special seal will prevent
the mix in one freezing cylinder from traveling into the
second cylinder.

Step 9
Slide the two o- rings into the grooves on the remaining
draw valves and lubricate.
Figure 17
Step 10
Lubricate the inside of the freezer door spouts from the
bottom. Insert the draw valves into the freezer door
from the bottom until the slot in the draw valves comes
into view.

Step 12
Slide the tip of the draw handle into the slot of the draw
valve, starting from the right. Slide the short pivot pin
through the far right draw handle. Slide the long pivot
pin through the far left and middle draw handles.
