Introduction

Beater Rotation
Beater rotation must be clockwise as
viewed looking into the freezing cylinder.
Note: The following repairs must be performed by
an authorized Taylor Service Technician.
Disconnect all power to the unit. Failure
to follow this instruction may result in electrocution.
To correct rotation on a three­phase unit,
interchange any two incoming power supply lines at
the freezer main terminal block only.
To correct rotation on a single­phase unit, change
the leads inside the beater motor by following the
diagram printed on the motor label.
Water Connections
(Water Cooled Units, Only)
An adequate cold water supply must be provided
with a hand shut-off valve. The water inlet and drain
connections are located on the underside of the
base. These connections are 3/8” FTP. (Refer to the
Model C723 Specifications on page 4.)
Flexible lines are recommended, if local codes
permit. In Europe, hose sets for connection of
appliances to the water mains must comply to the
International IEC 61770 standard.
The water expansion valve setting should be set at
255 PSIG (1758 kPa).
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
open trap drain.
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.
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 non­toxic and
non­flammable, 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.
Use only R404A refrigerant that conforms
to the AHRI 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.
