Water Connections
(Water Cooled Units Only)
An adequate cold water supply must be provided
with a hand shut-off valve. On the underside of the
base pan or on the right side, two 3/8” I.P.S. water
connections for inlet and outlet are 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 the incoming water connection side.
Please refer to the applicable National, State, and
local codes for determining the proper 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 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

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 on the freezer
for branch circuit overcurrent protection or fuse,
circuit ampacity, and other electrical specifications.
Refer to the wiring diagram provided inside the
electrical box, for proper power connections.
CAUTION: THIS EQUIPMENT MUST BE
PROPERLY GROUNDED! FAILURE TO DO SO
CAN RESULT IN SEVERE PERSONAL INJURY
FROM ELECTRICAL SHOCK!
DO NOT operate this freezer with larger
fuses than specified on the unit data label. Failure to
follow this instruction may result in electrocution or
damage to the machine.
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 equipments frame.
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.
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.
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.
