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
automaticwatervalve;second,throughthe
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.
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

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.
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
Beater rotation must be clockwise as viewed
looking into the freezing cylinder.
Note: Thefollowingproceduresshouldbe
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
printedonthemotor.)
Electrical connections are made directly to the
terminal block provided in the main control box located
under the upper left side panel on the Model 750, or
behind the service panel on the Models 751, 754, 774
and 794.
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 .

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
refrigerantsarebeingadvertisedasdrop--in
replacements for numerous applications. It should be
noted that, in the event of ordinary service to this
machine’s refrigeration system, only the refrigerantspecified 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 .
The Taylor Company 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 abovedisclaimer would
become null and void. To find out the current status of
an alternate refrigerant asit relatesto 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.
