The Correct Temperature; Setting The Temperature - Miele FN 12221 S Operating And Installation Manual

Frost-free freezer
Hide thumbs


It is very important to set the correct
temperature for storing food in the
appliance. Micro-organisms will cause
food which is not stored at the correct
temperature to deteriorate rapidly.
Temperature influences the growth rate
of these micro-organisms. Reducing
the temperature reduces their growth
To freeze fresh food and to store frozen
food for a long time, a temperature of
-18 °C is required. At this temperature
the growth of micro-organisms is
generally halted. As soon as the
temperature rises above -10 °C, the
micro-organisms become active in the
food again so that it cannot be kept as
long. For this reason, partially defrosted
or defrosted food must not be re-frozen.
Food may be re-frozen once it has
been cooked, as the high temperatures
achieved when cooking destroy most
The temperature in the appliance will
– the more often the door is opened
and the longer it is kept open,
– if too much food is stored in it at
– if too much fresh food is being frozen
at once,
– the higher the ambient temperature
surrounding the appliance.
The appliance is designed for use in
specific ambient temperatures
(climate ranges). Do not use in
ambient temperatures for which it is
not designed.

The correct temperature

Setting the temperature

^ Press the temperature selector button
repeatedly until the temperature you
want lights up in the display.
The first time the temperature selector
button is pressed, the last temperature
set will flash in the display.
With each subsequent press the
temperature value will change up until
the setting for -32 °C is reached. It will
then drop back to the -15 °C setting
The temperature can be set slightly
colder within the displayed temperature
range (e.g. between -15°C and -18 °C).
^ Press the temperature selector button
repeatedly until the indicator for
-15 °C lights up.
^ Press the temperature selector button
again for approx. 5 seconds to set
the temperature.
The colder temperature setting within
the small temperature range is now set.
However, this is not visible in the
temperature display.
