Refrigerant
Appliances 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.
In consideration of our environment, Taylor
proudly 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.
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.
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.
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.
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.
Beater Rotation
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.
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: The following procedures should be
performed by a trained service technician.
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.
To correct rotation on a single-phase unit, change the
leads inside the beater motor. (Follow the diagram
printed on motor.)

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, they 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.
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.
This Operator’s Manual should be read before
operating or performing any maintenance on your
equipment.
Compressor Warranty Disclaimer
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.
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.
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.
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.
Note: Constant research results in steady
improvements; therefore, information in this
manual is subject to change without notice.
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.
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

Power Switch
Standby Switch (Toggle 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.
This switch determines which mode of operation the
freezing cylinder is operating in. The left position
places the unit in the AUTO mode. The right position
places the unit in the STANDBY mode.
Display Light Switch
Note: The power switch must be in the AUTO position
in order for the standby switch to function.
The display light switch is located under the control
channel. The left position is “OFF”. The right position
is “ON”, and activates the display light.
Viscosity Adjustment
Reset Mechanism
The viscosity (thickness) of the product can be
adjusted by turning the viscosity adjustment screw on
the right side of the unit, 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 2 or 3 times to accurately evaluate the
viscosity.
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 two
or three 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.
Do not use metal objects to press the reset
button. Failure to follow this instruction may result in
electrocution.
Indicator Light - “ADD MIX”
A mix level indicating light is located 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 indicating light is located 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 unit,
refrigeration discontinues automatically when the MIX
OUT indicator light is flashing.

Operating Procedures
Note: To ensure that the 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.
The Model 428 freezer is designed to produce shake
or slush product at the desired thickness. This unit has
a 7 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 these 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 27, “Disassembly”, and start
there.

Operating Procedures
Section 7
Important: Operator Checklist
During Cleaning and Sanitizing:
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.
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.
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. Temperature of mix in mix hopper and walk-in
cooler should be below 40_F. (4.4_C.).
Regular Maintenance Checks:
CLEANING AND SANITIZING MUST BE
PERFORMED DAILY.
j 1. Replace scraper blades that are nicked,
damaged or worn down. Before installing the
beater, be certain the scraper blade is properly
attached.
Troubleshooting Bacterial Count:
j 2. Check rear shell bearing for signs of wear
(excessive mix leakage in drip pan) and be
certain it is properly cleaned.
j 1. Thoroughly clean and sanitize machine
regularly, including complete disassembly and
brush cleaning.
j 3. Using a screwdriver and cloth towel, keep the
rear shell bearing and the female square drive
socket clean and free of lubricant and mix
deposits.
j 2. Use all brushes supplied for thorough cleaning.
The brushes are specially designed to reach all
mix passageways.
j 4. Dispose of o-rings and seals if they are worn,
torn, or fit too loosely, and replace with new
ones.
j 3. Use the white bristle brush to clean the mix feed
tube, which extends from the hopper down to
the rear of the freezing cylinder.
j 5. Follow all lubricating procedures as outlined in
“Assembly”.
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 6. Check the condenser(s) for accumulation of dirt
and lint. Dirty condensers 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.
Note: For machines equipped with an air filter,
it will be necessary to vacuum clean the filters
on a monthly schedule.
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 used the following day. DO NOT
prime the machine with rerun. When using
rerun, skim off the foam and discard, then mix
