Air Cooled Units
DO NOT obstruct air intake and discharge openings:
Air cooled units require a minimum of 6” (152 mm)
of clearance on both sides of the freezer. It is
recommended to place the rear of the unit against
the wall to prevent recirculation of warm air. Failure
to allow adequate clearance can reduce the
refrigeration capacity of the freezer and possibly
cause permanent damage to the compressors.
Water Connections
(Water Cooled Units Only)
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. 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!
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.
An adequate cold water supply must be provided
with a hand shut-off valve. On the underside rear of
the base pan, two 3/8” I.P.S. (for single-head units)
or two 1/2” I.P.S. (for double-head units) water
connections for inlet and outlet have been 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 for both single-head and double-head
units. 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.
CAUTION: THIS EQUIPMENT MUST BE

Model 490To the Installer
SAppliances 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.
SSupply 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.
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.
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: The following procedures must be performed
by an authorized Taylor 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 main control box.
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 2To the Operator
The freezer you have purchased has been carefully
engineered and manufactured to give you
dependable operation. The Taylor Model 490, 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.
The Operator's Manual should be read before
operating or performing any maintenance on your
equipment.
The Model 490 will NOT eventually compensate and
correct for 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: 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
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 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 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 is
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 Taylor Distributor or the Taylor Factory. Be
prepared to provide the Model/Serial Number of the
unit in question.
