Indesit SFR 167NF User Manual

Install it well
This means that the appliance should be installed away 
from  heat  sources  or  direct  sunlight  in  a  well-ventilated 
room.

Correct temperature settings
Set the freezer temperature knob to one of the medium 
settings. Very low temperatures will not only consume a 
great deal of energy but will neither improve or lengthen 
the storage life of the food. Excessively low temperature 
may in fact spoil vegetables, cold meats and cheese.

Do not overfill 
Remember that proper storage of food requires good air 
circulation. Overfilling your appliance will prevent this 
circulation and overwork the compressor.

Shut the doors
Open your appliance only when strictly necessary;
remember  that  every  time  you  open  the  door  most  of 
the cold air will be lost. The motor will have to run, and 
consume energy, to restore the correct temperature.

Check the door gaskets
Keep  the  gaskets  clean  and  soft  so  that  they  fit  closely 
against the door to ensure that no cold air is lost.

Never store hot foods
A container of hot food in the freezer will increase the 
temperature significantly; allow food to cool to room 
temperature before storing.
