Temperature indicator
To help you set the right device, it is equipped with a
temperature indicator placed in the coldest area.
For the good conservation of foodstuffs in your refrigerator and in
particular in the coldest zone, take care that in the temperature
indicator "OK" appears.
The symbol opposite indicates the location of the
coldest area of your refrigerator. It defines the top
of this area.
If "OK" does not appear, the average temperature
of this zone is too high.
Set the thermostat to a cooler position. Each time
the thermostat setting is changed, wait for the
temperature inside the appliance to stabilize before
making a new setting if necessary. Change the
thermostat position only gradually and wait at least
12 hours before checking again.
NOTE: after loading the appliance with fresh food or after
repeated or prolonged door openings, it is normal for the
inscription "OK" not to appear in the temperature indicator; wait at
least 12 hours before readjusting the thermostat.
