Water Connections
(Water-Cooled Machines Only)
An adequate cold water supply must be provided with a
hand shutoff valve. On the underside of the base pan,
two 3/8 in. IPS (for single-head units) or two 1/2 in. IPS
(for double-head units) inlet and outlet water connections
have been provided for easy hook-up. Connect 1/2 in.
inside diameter water lines to the machine. (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.
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.
!
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.
Air-Cooled Machines
Air-cooled machines require a minimum of 6 in. (152 mm)
of clearance around both sides and 0 in. at the rear of the
freezer. This is required 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(s).
Electrical Connections
Each freezer requires one power supply. Check the data
label on the freezer for branch circuit overcurrent
protection or fuse, circuit ampacity, and electrical
specifications. Refer to the wiring diagram provided
inside the electrical box for proper power 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. Compliance therewith and proper maintenance
will result in an installation essentially free from hazard.
In all other areas of the world, equipment should be
installed in accordance with the existing local codes.
Please contact your local authorities.
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 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
device with a contact gap of at least 0.125 in. (3
mm) installed in the external installation.
• Machines 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
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
