Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided with
a hand shut- off valve. On the underside rear of the
base pan, two 3/8” 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
open trap drain.
A back flow prevention device is required
on the incoming water connection side.
Please
refer to the applicable National, State, and local codes
for determining the proper configuration.
Electrical Connections
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.
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. 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.
FOLLOW YOUR LOCAL ELECTRICAL CODES!
CAUTION: THIS EQUIPMENT 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 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 or 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 the 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.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service
agent, or similarly qualified person, in order to
avoid a hazard.
