articles.

The indicated temperature of this product may have a certain difference with the actual 
temeprature inside the boxes due to refrigeration intertia, this is normal.

All the freezers are of storage equipment, and it is strictly forbidden to put excessive articles that 
are relatively too hot in one go, this will cause long time of running of the compressor without 
stop, slow drop of temperature, thus affecting service life of the compressor, the articles must be 
put in batches so that the temperature drops in steps till the required temperature is reached.

Do not spoil the refrigerating circuit.

Inside the freezer, do not use the electric appliance without production permission.
