Miele FN 12620 S - Manual (Page 23)

This freezer is equipped with a Frost
free system. The freezer defrosts
automatically.
The moisture generated by defrosting
collects in the condensor and is
automatically dissipated by the
condensor from time to time.
This automatic defrosting system
enables the freezer to remain
permanently ice-free, however, the food
stored in the freezer will not defrost.
