Air Cooled Units
DO NOT obstruct air intake and discharge openings:
The Model 342 air cooled unit requires a minimum of
3” (76 mm) air space around all sides. Install the
deflector to prevent recirculation of warm air.
Failure to allow adequate clearance can reduce the
refrigeration capacity of the freezers and possibly
cause permanent damage to the compressors.
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 open trap drain.
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
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. 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!
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 the electrical box for proper power
connections.
CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY

Stationary 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.
Appliances that are permanently connected
to fixed wiring and for which leakage
currents may exceed 10 mA, particularly
when disconnected, 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 authorized personnel to the local
codes.
Supply 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 an authorized Taylor service
technician in order to avoid a hazard.
Beater Rotation
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: The following procedures must be performed
by an authorized Taylor service technician.
To correct rotation on a single-phase unit, change
the leads inside the beater motor. (Follow the
diagram printed on the motor.)
Refrigerant
In consideration of our environment, Taylor
uses only 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 are 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.

4Model 342 Tim HortonsTo the Operator
131122
Section 2 To the Operator
The freezer you purchased has been carefully
engineered and manufactured to give you
dependable operation. When properly operated and
cared for, it 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.
Your Taylor freezer will NOT eventually compensate
for and correct 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 review these procedures in
order to be properly trained and to make sure no
misunderstandings exist.
If you 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.
Note: Constant research results in steady
improvements; therefore, information in this
manual is subject to change without notice.
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 the
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.
Taylor will continue to monitor the refrigerant
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.

light is flashing, it indicates that the hopper is empty
and the mix supply needs to be replenished. To
prevent damage to the unit, refrigeration stops
automatically.
Indicator Light - ADD MIX
The ADD MIX indicator lights are located on the
front of the machine. An ADD MIX indicator light will
flash and an audible tone will sound when a mix
hopper has a low supply of product. Refill the hopper
as soon as possible.
Reset Button
The reset buttons are located in the service panel on
the lower front of the machine. The reset protects
the beater motor from an overload condition. If an
overload occurs, the reset mechanism will trip. To
properly reset the freezer, place the power switch in
the OFF position. Press the reset button firmly.
Place the power switch in the WASH position and
observe the freezer's performance. Once satisfied,
place the power switch back in the AUTO position.
IMPORTANT: Do not use metal objects to

instruction may result in serious electrical shock.

14 Model 342 Tim HortonsOperating Procedures
Section 6 Operating Procedures
The Model 342 is designed to produce slush product
at the desired thickness. It has two 20 quart (18.9
liter) mix hoppers and two 7 quart (6.6 liter) freezing
cylinders.
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 brush cleaning.
These opening procedures will show you how to
assemble the parts into the freezer, sanitize them,
and prime the freezer with fresh mix in preparation
to serve your first portion.
If you are disassembling the machine for the first
time or need information to get to this point in our
instructions, turn to page 22, “Disassembly”, and
start there.
Assembly
Note: When lubricating parts, use an approved food
grade lubricant (example: Taylor Lube).
MAKE SURE THE POWER SWITCH IS IN
THE “OFF” POSITION! Failure to follow this
instruction may result in severe personal injury from
hazardous moving parts.
Step 1
Lubricate both grooves on the drive shaft and slide
the o-ring in place. Lubricate the o-ring and shaft
portion that comes in contact with the bearing. DO
NOT lubricate the square end of the drive shaft.
Slide the boot seal over the shaft and groove until it
snaps into place. Fill the inside portion of the seal
with 1/4” more lubricant and evenly lubricate the end
of the seal that fits onto the rear shell bearing.
Figure 5
Note: To ensure that mix does not leak out of the
back of the freezing cylinder, the middle section of
the boot seal should be convex or extend out from
the seal. If the middle section of the boot seal is
concave or extending into the middle of the seal,
invert the seal.
Figure 6

Step 2
Insert the beater drive shaft into the rear shell
bearing. Engage the square end firmly into the
female socket of the drive unit. Be certain that the
drive shaft fits into the drive coupling without
binding.
Figure 7
Step 3
Check the scraper blades for any nicks or signs of
wear. If any nicks are present or if the blade is worn,
replace both blades. If the blades are in good
condition, place the rear scraper blade over the rear
holding pin (knife edge to the outside). Holding the
blade on the beater, turn it over and install the front
blade the same way.
Figure 8
Step 4
Holding the blades in position, insert the beater
assembly into the freezing cylinder and slide it into
position over the drive shaft. Turn the beater slightly
to be certain that the beater is properly seated.
When it is in position, the beater will not protrude
beyond the front of the freezing cylinder.
Figure 9
