Air Cooled Units
DO NOT obs truct 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 a ir flow acr oss the condensers. A deflector
is 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 compressor.
Water Connections
(Water Cooled Units On ly)
An adequate cold water supply must be provided with
a hand shut- off valve. On the underside rear of the
base pan, two 1/2” I.P.S. water connect ions for inlet
and outlet have been provided for easy hook- up. 1/2”
inside diameter water lines should be connected tothe
machine. (Flexible lines are recommended, if local
codes permit.) Depending on local water conditions, it
may be advisable to install a water st rainer to prev ent
foreign substances from clogging the automatic water
valve. There will be only one water “in” and one water
“out” connection for both single- head and
double- head units. DO NOT install a hand shut- off
valve on the water “out” line! W ater should always flow
in this order: first, through the automatic water valve;
second, through the condenser; and third, through the
outlet fitti ng to an opentrapdrain.
A back flow preventi on device is required
on the incoming water connection side. P lease
refer to the applicable National, State, and local codes
for determining the proper configuration.
