Air-Cooled Units
Do not obstruct air intake and discharge openings.
The model 702 requires a minimum of 6 in. (152 mm) of
clearance around both sides of the freezer. Install the
deflector on the right side of the unit and place the back
of the unit against the wall to prevent recirculation of
warm air. The models 741 and 772 require a minimum of
3 in. (76 mm) of clearance around all sides. Install the
deflector provided. Failure to allow adequate clearance
can reduce the refrigeration capacity of the freezers and
possibly cause permanent damage to the compressors.
Water Connections
(Water-Cooled Units Only)
An adequate cold water supply must be provided with a
hand shutoff valve. On the underside rear of the base
pan, two 3/8 in. IPS (for single-head units) or two 1/2 in.
IPS (for double head units) water connections for inlet
and outlet have been provided for easy hookup. 1/2 in.
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
necessary 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 shutoff 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.
!
IMPORTANT! A backflow prevention device is
required on the incoming water connection side. Please
see 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.
Each freezer requires one power supply for each data
label. Check the data label(s) on the freezer for branch
circuit overcurrent protection or fuse, wire ampacity, and
electrical specifications. See the wiring diagram provided
inside the electrical box for proper power connections.
WARNING! This machine must be properly
grounded. Failure to do so can result in severe personal
injury from electrical shock.
IMPORTANT! An equipotential grounding lug is
provided with this machine. Some countries require the
grounding lug 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
machine's frame.
IMPORTANT!
• 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 0.125 in. (3
mm) 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 to
protect against the leakage of current, such as a
Ground Fault Interrupter (GFI), installed by the
authorized personnel to the local codes.
• Supply cords used with this machine 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.
If the supply cord is damaged, it must be replaced by an
authorized Taylor service technician in order to avoid a
hazard.
Check Out
Once the unit is installed, it is advisable to check the
following controls and mechanical operations of the
freezer and 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 condenser fan). The dial light and the mix low
indicator will be lit.
Figure 1-1
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
NOTICE! Beater rotation must be clockwise as
viewed looking into the freezing cylinder.
To correct the rotation on a three-phase machine,
interchange any two incoming power supply lines at the
freezer main terminal block only. To correct rotation on a
single-phase machine, 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.
It is recommended that beater rotation be performed by
an authorized Taylor service technician.
Refrigerant
CAUTION! In consideration of our environment,
Taylor uses only earth-friendly hydro-fluorocarbon (HFC)
refrigerants. The HFC refrigerant used in this machine 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.
!
CAUTION! Use only R404A refrigerant that
conforms to the Air-Conditioning, Heating and
Refrigeration Institute (AHRI) standard 700 specification.
The use of any other refrigerant may expose users and
operators to unexpected safety hazards.
WARNING! Refrigerant liquid sprayed onto the
skin may cause serious damage to tissue. Keep eyes

NOTICE! Taylor reminds technicians to be
aware of and in compliance with local government laws
regarding refrigerant recovery, recycling, and reclaiming
systems. For information regarding applicable local laws,
please contact your local authorized Taylor distributor.
!
IMPORTANT! 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.
