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 unit requires one power supply for each data
label on the unit. Check the data label(s) on the freezer
for branch circuit overcurrent protection or fuse, circuit
ampacity, and other electrical specifications. Refer to
the wiring diagram provided inside of the electrical box
for proper power connections.
FOLLOW YOUR L OCAL ELECTRICAL CODES!
CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!
Note: This unit is provided with an equipotential
grounding lug that is to be properly attached to either
the rear of the frame or the under side of the base pan
near the entry hole for incoming power, 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
equipment’s frame, as well as on the diagram.
S DO NOT operate the freezer with larger
fuses than specified on the data label.
S 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 3 mm installed in the external
installation.
S Appliances that are permanently connected
to fixed wiring and for which leakage
currents may exceed 10 mA, particularly
when disconnected, not used for long
periods, or during initial installation, shall
have protective devices such as a GFI to
protect against the leakage of current,
installed by authorized personnel to the local
codes.
S Supply cords used with this unit 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.
Failure to follow these instructions may result in
electrocution or damage to the machine.
Water Cooled Units
An adequate cold water supply with a hand shut-off
must be provided.
Step 1
Flush all water lines.
Step 2
Connect a 3/8” inside diameter water line to the 3/8”
I.P.S. inlet water connection.
Note: If local codes permit, use flexible water lines.
Local water conditions may make it necessary to install
a water strainer to prevent foreign substances from
clogging the automatic water valves.
Step 3
Connect a 3/8” inside diameter flexible drain line to the
outlet connection.
Step 4
Install the drain line into an open trap drain so the drain
water can be observed.
IMPORTANT: Do not install a shut--off valve on the
drain line.
