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
airflow 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 rear of the machine, 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 machine must be properly
grounded. Failure to do so can result in severe personal
injury from electrical shock.
IMPORTANT! This machine is provided with an
equipotential grounding lug that is to be properly
attached by the authorized installer to either the rear of
the frame or the underside of the base pan near the entry
hole for incoming power. 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, as well as on the diagram.
WARNING! Avoid injury.
• DO NOT operate the machine unless it is
properly grounded.
• DO NOT operate the machine with fuses larger
than specified on the machine's data label.
FOLLOW YOUR LOCAL ELECTRICAL CODES.
