DEFROSTING
The number and duration of defrosts in both no-unit cases and cases with self-contained unit are factory-set. The user must
never alter their adjustment.
Defrost-water is collected by a drain tube and conveyed to an evaporation tray located in the base of the display cabinet.
Periodically check that defrost water flows off normally. Otherwise, unclog by the use of a pointless flexible probe.
