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. I nstall the
deflector provided to prevent recirculation of warmair.
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 wit h
a hand shut--offvalve. On the rear of the unit, two 1/2”
I.P.S.water connectionsfor inlet and outlet havebeen
provided for easy hook--up.1/2” inside diameterwater
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 wat er valve; second,
through the condenser; and third, through t he outlet
fitting to an opentrapdrain.
A back flow prevention devi ce isreq uired
on the incoming water connectio n side. Please
refer to the applicable National, State, and local codes
for determining the proper configuration.
Electrical Connections
In the United States, this equipment isintended tobe
installed in accordance with the National Electrical
Code(NEC), A NSI/NFPA70-1987. T hepur pose 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.
FOLLOW YOUR LOCAL ELECTRICAL CODES!
Each unit requires one power supply for each data
labelon t he unit. Check the data label(s) on the freezer
for branch circuit overcurrent protection or fuse, c ircuit
ampacity, and other electrical specifications. Refer to
the wiring diagram provided inside of the electrical box
for proper power connections.
CAUTION: THIS EQUIPMENT M UST 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
oft he frame by the authorized installer. The inst allation
location is marked by the equipotential bonding
symbol (5021 of IEC 60417-1) on both the removable
panel and the equipment’s frame.
SStationary 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.
SAppliances 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.
SSupply 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 fr om
abrasion.
