Air-Cooled Machines
Important! Do not
obstruct air intake and discharge
openings.
Air-cooled machines require a minimum of 3 in. (76 mm)
of clearance around all sides of the freezer and 12 in.
(305 mm) on the top of the freezer to allow for adequate
air flow across the condenser(s). Failure to allow
adequate clearance can reduce the refrigeration capacity
of the freezer and possibly cause permanent damage to
the compressor.
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 machines) or two
1/2 in. IPS (for double-head machines) 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 machines.
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
IMPORTANT!
In the United States, this
machine is intended to be installed in accordance with
the National Electrical Code (NEC), ANSI/NFPA 701987.
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, the machine should be
installed in accordance with the existing local codes.
Please contact your local authorities if you have any
questions.
Each machine requires one power supply for each data
label on the machine. Check the data label(s) on the
machine 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 equipment 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.
FOLLOW YOUR LOCAL ELECTRICAL CODES.
