Air Cooled Units

DO NOT obstruct air intake and discharge openings:

existing local codes. Please contact your local
authorities.

Air cooled units require a minimum of 3” (76 mm) of
clearance around all sides of the freezer to allow for
adequate air flow across the condensers. Install the
deflector provided 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 compressor.

Water Connections

(Water Cooled Units Only)

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.

Electrical Connections

In the United States, this equipment is intended to be
installed in accordance with the National Electrical
Code (NEC), ANSI/NFPA70-1987. 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

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.

Check Out

Once the unit is installed, it is advisable to check the
following controls and mechanical operations of the
freezer and to make any necessary adjustments. If
applicable, repeat these checks for the second
freezing cylinder on double head units.

Controls

Place the control switch in the “AUTO” position. The
main refrigeration system will operate (compressor,
beater motor, and the condenser fan). The dial light
and the mix low indicator will be illuminated.

Refrigerant

In consideration of our environment, T aylor
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.

Figure 1

If the freezer is water cooled, the automatic water
valve will begin to open and cold water will flow into the
condenser. This will remove heat from the refrigerant.
As the water flows into the open trap drain, it should be
warm to the touch. Place the control switch in the
“OFF” position.

Beater Rotation

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 rotation on a three--phase unit, interchange
any two incoming power supply lines at the freezer
main terminal block only. To correct rotation on a
single--phase unit, exchange 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 located
behind the service panel.

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.

manual is subject to change without notice.

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 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.

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.

080924

To th e Operator

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.
