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.

131125
Section 2 To the Operator
The freezer you have purchased has been carefully
engineered and manufactured to give you
dependable operation. The Taylor Model 432, 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.
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, both assembly and
disassembly, sit down together and go through
these procedures 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.
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 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.
Taylor 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.

hopper has a low supply of product. Refill the hopper
as soon as possible.
Indicator Light - “Mix Out”
The MIX OUT indicator lights are located on the
front of the machine. When a MIX OUT indicator
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. Refrigeration will restart 30 seconds
after the mix supply is replenished.
Viscosity Adjustment
The viscosity (thickness) of the slush can be
adjusted by turning the viscosity adjustment screw,
located under the control channel. Turn the viscosity
adjustment screw clockwise for a thicker product, or
counterclockwise for a thinner product. After making
an adjustment, allow the refrigeration system to
cycle 2 or 3 times to accurately evaluate the

Model 432 Tim Hortons Operating Procedures
Section 6 Operating Procedures
The Model 432 freezer is designed to produce slush
product at the desired thickness. This unit has a four
quart 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 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 23, “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 the groove 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.
Lubricate the boot seal groove and 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

16 Model 432 Tim HortonsOperating Procedures

Step 2
Insert the beater drive shaft into the rear shell
bearing and 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
