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 of the electrical box for proper power
connections.

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

CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!

DO NOT operate this freezer with larger
fuses than specified on the unit data label. Failure to
follow this instruction may result in electrocution or
damage to the machine.

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 equipment's frame.

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.

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 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

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.

2

Model C722To the Installer

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.

Beater Rotation

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.

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 the 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 the
diagram printed on the motor.)

Electrical connections are made directly to the
terminal block provided in the splice box.

Optional Carts

There are two optional carts available.

1. C20600-AFB: ADA compliant height cart,

not equipped with a door.

2. C20600-000: Standard height cart with

reversible front door panel and rear panel.
Note: If the door is required on the rear of the

cart instead of the front, the front door panel
and the rear panel can be reversed. To reverse
these panels, remove the five screws on each
panel. Reverse and reinstall the panels, making
sure all screws are reinstalled.

IMPORTANT! For safety purposes, the

freezer must be bolted to the cart using all 4
bolts. Failure to comply could result in personnel

injury and equipment damage.

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

Use only R134a refrigerant that conforms to
the AHI 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.

Section 2 To the Operator

Your freezer has been carefully engineered and
manufactured to give you dependable operation.

This unit, 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, 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: 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 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.
