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. 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. 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.

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.

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.

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. 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!

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.

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.

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.

Model C706To 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

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.

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.

To correct rotation on a single--phase unit, change the
leads inside the beater motor. (Follow the diagram
printedonthemotor.)

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

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

The Model C706 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.

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.

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.

080714

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.
