CONDENSING UNIT –
The condensing unit is mounted on a
slideout base, accessible by removing the
rear serving side access panel.
The
condenser is of the baretube design. The
condenser
fan
motor
draws
the
air
through the rear access panel, across the
compressor and discharges back out the
rear access panel unless the case has been
Field converted to front air discharge as
previously
discussed
in
the
Location
section of this manual.
For this reason, if
the case is installed in a counter, provisions
must be made for the release of the
discharge air.
CLEANING THE CONDENSER –
To clean condenser, a soft, nylon brush
should be used to loosen dirt and lint.
Then
vacuum
up
the
dirt
or
blow
condenser out with a high-pressure gas
such as nitrogen. Never use a wire brush
to clean condenser tubes.

base area.
Disconnect
the
electrical
power and allow cabinet to warm to
above freezing temperature. Use a soft
cloth or sponge with a mild detergent to
wash the interior.
Wipe dry before
restarting the cabinet. Allow the cabinet
to cool down to proper temperature
before reloading product.
SERIAL PLATE LOCATION –
One serial plate is located on the interior
left wall of the cabinet, and a second one
in
the
condensing
unit
compartment.
Both contain all pertinent information
such as model, serial number, amperage
rating, refrigerant type and charge, etc.
