Water Connections

(Water Cooled Units Only)

An adequate cold water supply must be provided
with a hand shut-off valve. On the underside of the
base pan or on the right side, two 3/8” I.P.S. water
connections for inlet and outlet are 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

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 equipments frame.

S 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 3mm installed in the external
installation.

S 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.

S 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.

Each freezer requires one power supply for each
data label. Check the data label on the freezer for
fuse, circuit ampacity and electrical specifications.
Refer to the wiring diagram provided inside of the
electrical box, for proper power connections.

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 behind the lower front panel.

Refrigerant

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.

NEVER fill any refrigerant cylinder completely with
liquid. Filling the cylinder to approximately 80% will
allow for normal expansion.

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

Your freezer 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, cleaning and maintenance will
be required. 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, go through these procedures together
in order to be properly trained and to make sure that
no confusion exists.

In the event you should require technical assistance,
please contact your local authorized Taylor
Distributor.

Note: Warranty is valid only if the parts are
authorized Taylor parts, purchased from an
authorized Taylor Distributor, and the required
service work is provided by an authorized Taylor
service technician. Taylor reserves the right to deny
warranty claims on equipment or parts if
non-approved parts or refrigerant were installed in
the machine, system modifications were performed
beyond factory recommendations, or it is determined
that the failure was caused by neglect or abuse.

Note: Con st ant research results i n 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 compressors on this machine are
warranted for the term indicated on the warranty
card accompanying this machine. 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 compressor warranty. It will be the
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.

Symbol Definitions

Power Switch

When placed in the ON position, the power switch
allows control panel operation.

To better communicate in the International arena,
symbols have replaced words on many of our
operator switches, function, and fault indicators.
Your Taylor equipment is designed with these
International symbols.

The following chart identifies the symbol definitions.

Fluorescent Display

The fluorescent display is located on the front
control panel. During normal operation the display is
blank. The display is used to show menu options
and notifies the operator if a fault is detected. On
International models, the display will indicate the
temperature of the mix in the hopper.

Indicator Lights

MIX LOW - When the MIX LOW symbol is

illuminated, the mix hopper has a low supply of mix
and should be refilled as soon as possible.

MIX OUT - When the MIX OUT
illuminated, the mix hopper has been almost
completely exhausted and has an insufficient supply
of mix to operate the freezer. At this time, the AUTO
mode is locked out and the freezer will be placed in
the STANDBY mode. To initiate the refrigeration

Operating Screen Descriptions

The fluorescent display located in the center of the
control panel is normally blank during the daily
operation of the machine. The display is activated
when the SEL symbol or the Manager's Menu is
selected. The display screen will also alert the
operator of specific faults detected by the control.

Note: The following operating screen examples will
be displayed as they appear on a C709. The C717
will display information for the second freezing
cylinder.

The SAFETY TIMEOUT screen will be displayed
with the alarm on, for 60 seconds or until any control
symbol is selected.

After the safety timeout has been completed and the
power switch is OFF, the following screen is
displayed.

DO NOT attempt to draw product or
disassemble the unit during the HEAT cycle. The
product is hot and under extreme pressure.

In the HEAT cycle, the mix temperature in the
hopper and freezing cylinder must be raised to
151°F (66.1°C) within 90 minutes.

When the heating phase is complete, the freezer
goes into the holding phase of the cycle. The holding
phase will keep the temperature above 151°F
(66.1°C) for a minimum of 35 minutes.

The final phase of the heat treatment cycle is the
cooling phase. The freezer must cool the mix below
41°F (5°C) within 90 minutes.

When the entire heat cycle has been completed, the
HEAT symbol

will no longer be illuminated. The

machine will enter the STANDBY mode (STANDBY
symbol

illuminates). The machine can be placed

in AUTO or left in STANDBY.

To comply with health codes, heat treatment system
freezers must complete a heat treatment cycle
daily, and must be disassembled and brush cleaned
a minimum of every 14 days. Brush cleaning is the
normal disassembly and cleaning procedure found in
this manual. Failure to follow these guidelines will
cause the control to lock the freezer out of the
AUTO mode.

Always comply with local guidelines for the
maximum number of days allowed between brush
clean cycles. (See the Manager's Menu for setting
the Brush Clean int er v al, on page 24.)

Freezer Locks

There are two types of freezer lock conditions that
can occur: Hard Lock or Soft Lock. A Hard Lock
requires the machine be disassembled and brush
cleaned. A Soft Lock can be corrected by either
disassembling and brush cleaning the machine, or
by starting another heat treatment cycle.

Hard Lock: There are two causes of a hard lock
failure:

1. The brush clean timer has elapsed
(maximum setting of 14 days).
