As the thermostat is moved closer to the MAX position, the
temperature inside the refrigerator will become lower.
NOTE: The refrigerator can operate at lower temperatures than the
level obtained by setting the thermostat to MAX by turning the dial
clockwise past this setting and as far as it will go. However, since these
temperatures are out of the range for storing milk, the manufacturer
advises against using the refrigerator in this way.
Once switched on, the refrigerator will begin to operate, but a certain
amount of time is needed (depending on external conditions as well as
on the thermostat setting) for it to reach the required internal
temperature.
We recommend to inserting milk inside the refrigerator only once the
internal temperature has stabilized.
7.4.2 Setting (electronic thermostat)
In the refrigerator equipped with electronic thermostat, it is generally
placed on the frontal panel.
