5.8 SuperFrost
With this function you can freeze fresh food quickly
through to the core. The appliance operates with
maximum refrigeration. The noise of the refrigeration
unit may be temporarily louder as a result.
The maximum amount of fresh food which can be frozen in 24
h is indicated on the type plate under “freezing capacity ... kg/
24h”. This amount varies according to the model and climate
rating.
You have to activate SuperFrost in good time, depending on
how much fresh food is to be frozen: about 6 hours before
placing the food inside in case of small amounts and about 24
hours in advance in case of the maximum amount of food to be
frozen.
Wrap produce and spread it out as far as possible. Do not
allow produce to be frozen to touch produce that is already
frozen to prevent the latter thawing.
You do not have to activate SuperFrost in the following cases:
- when placing frozen food in the freezer
- when freezing up to approx. 2 kg fresh food daily
