To ensure temperatures in this area, be careful not to change the
positioning of this shelf. In refrigerators with forced air (equipped with a fan
or No Frost models), the symbol of the coldest zone is not represented
because the temperature inside them ishomogeneous.
Installing the temperature indicator
To help you adjust your refrigerator, it is equipped with a temperature
indicator that will control the average temperature in the coldest area.
CAUTION: This indicator is intended to work only with your refrigerator,
be careful not to use it in another refrigerator (in fact, the coldest area is
not the same), or for any other use.
Checking the temperature in the coldest zone
Thanks to the temperature indicator, you can check regularly that the
temperature of the coldest zone is correct. Indeed, the temperature inside
the refrigerator is a function of several factors such as the ambient
temperature of the room, the amount of food stored, the frequency of
opening the door. Take these factors into consideration when setting the
device.
When the indicator reads "OK", it means that your thermostat is set
correctly, and that the indoor temperature is correct.
If the color of the indicator is white, it means that the temperature is too
high, it is necessary in this case to increase the setting of the thermostat
and to wait 12 hours to carry out a new
visual control of the indicator.
After loading or opening the door, the indicator may turn white after a few
moments.
