Air Cooled Units
DO NOT obstruct air intake and discharge openings:
Air cooled units require a minimum of 3” (76 mm) of
clearance around all sides of the freezer to allow for
adequate air flow across the condensers. Install the
deflector provided to prevent recirculation of warm air .
Failure to allow adequate clearance can reduce the
refrigeration capacity of the freezer and possibly
cause permanent damage to the compressors.
Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided with
a hand shut--off valve. On the rear of the unit, two 1/2”
I.P.S. water connections for inlet and outlet have been
provided for easy hook--up. 1/2” inside diameter water
lines should be connected 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 opentrapdrain.
A back flow prevention device is required
on t he incoming water connection side. Please
refer to the applicable National, State, and local codes
for determining the p roper configuration.
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 haz ards arising from t he use o f
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.
FOLLOW YOUR LOCAL ELECTRICAL CODES!
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.
CAUTION: THIS E QUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!
This unit is provided with an equipotential
grounding lug that is 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 equipment’s frame.
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 a n 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.
