To the Operator
The freezer you have purchased has been carefully
engineered and manufactured to give you dependable
operation. The Taylor Model 428, 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 machine.
Your Taylor freezer will not eventually compensate for
and correct any errors during the setup or filling
operations. Thus, the initial assembly and priming
procedures are of extreme importance. It is strongly
recommended that personnel responsible for the
machine’s operation, both assembly and disassembly, go
through these procedures together to be properly trained
and to make sure no misunderstandings exist.
In the event you should require technical assistance,
please contact your local 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 a Taylor service technician.
Taylor reserves the right to deny warranty claims on
machines or parts if unapproved parts or incorrect
refrigerant were installed in the machine, 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.
IMPORTANT! If the crossed-out, wheeled-bin
symbol is affixed to this machine, it signifies that this
machine is compliant with the EU Directives as well as
other similar end-of-life 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 machine to the
appropriate collection facility, as specified by your local
code.
For additional information regarding applicable local
disposal laws, please contact the municipal waste facility
and/or local authorized Taylor distributor.
Compressor Warranty Disclaimer
The refrigeration compressor(s) on this machine 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 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 Taylor compressor warranty. It
is the machine owner's responsibility to make this fact
known to any technician he/she 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 5-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 machine in question.

Power Switch
The center position is OFF. The right position is AUTO,
which activates the beater motor and the refrigeration
system. The left position is WASH, which activates the
beater motor only.
Display Light Switch
The display light switch is under the control channel. The
left position is OFF. The right position is ON and activates
the display light.
Viscosity Adjustment
The viscosity (thickness) of the product can be adjusted
by turning the viscosity adjustment screw on the right
side of the machine, under the display light. 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 two or three times to accurately evaluate the
viscosity.
Indicator Light—ADD MIX
An ADD MIX indicator light is on the front of the machine.
The light flashes to indicate when the mix hopper has a
low supply of product and should be refilled as soon as
possible.
Indicator Light—MIX OUT
A MIX OUT indicator light is on the front of the machine.
When the light is flashing, it indicates that the hopper is
empty and the mix supply needs replenishing. To prevent
damage to the machine, refrigeration discontinues
automatically when the MIX OUT indicator light is
flashing.
Standby Switch—(Toggle Switch)
This switch determines which mode of operation the
freezing cylinder is operating in. The left position places
the machine in the Auto mode. The right position places
the machine in the Standby mode.
Note: The power switch must be in the AUTO position
for the Standby switch to function.
Reset Mechanism
Should an overload condition occur, the freezer will
automatically shut down. To properly reset the freezer,
place the toggle switch in the OFF position. Wait 2 or 3
minutes, then press the RESET button located in the left
side panel. Place the toggle switch in the WASH position
and observe the freezer's performance. Return the toggle
switch to the AUTO position.
CAUTION! DO NOT use metal objects to press
the RESET button. Failure to follow this instruction may
result in electrocution.
