Operation
The temperature controller and probe indicate when the refrigeration system is required to turn on and off.
The refrigeration system removes heat from the cabinet interior and rejects it to the surrounding room air. When
the cabinet interior temperature rises above the controller cut-in temperature, the controller turns the refrigeration
system on.
Defrosting
Undercounter refrigerators do not require manual defrosting. The unit cooler defrosts automatically when the
condensing unit is in the OFF cycle. The condensate drains out of the unit to the condensate tray mounted on top
of the compressor.
