injury or damage to the machine.
The authorized installer should inspect the machine and
promptly report any damage to the local authorized
Taylor distributor.
This machine is made using USA sizes of hardware. All
metric conversions are approximate and vary in size.
Water Connections
(Water-Cooled Machines 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.
Permanently connect the machine using 1/2 in. (12.7
mm) inside diameter water lines. (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 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. Water pressure to
the unit must not exceed 150 psi (1034 kPa).
Electrical Connections
In the United States, this machine 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, machines should
be installed in accordance with the existing local codes.
Please contact your local authorities.
Each machine requires one power supply for each data
label on the machine. Check the data label(s) on the
freezer for branch circuit overcurrent protection or fuse,
circuit ampacity, and other 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.
WARNING! DO NOT operate this freezer with
fuses larger than specified on the machine data label.
Failure to follow this instruction may result in
electrocution or damage to the machine.
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 machines which are not equipped
with a power cord and a plug or another device
to disconnect the machine from the power
source must have an all-pole disconnecting
