Energy-saving measures
In order to reduce the power consumption of your appliance:
 Install it in a suitable location (see "Installing your appliance").
 Leave the doors open for the shortest time possible.
 Never put hot food in the fridge or the freezer, and in particular soups and other preparations
that release a lot of steam.
 Check that your appliance is working correctly and do not allow too much ice to accumulate
(defrost when the ice is more than 5-6 mm thick). Clean the condenser on a regular basis.
 Regularly check the door seals and make sure that the doors can be closed properly. If this
is not the case, contact after-sales service.
 Do not adjust the temperature too low.
Storing food
Here are some rules you should follow:
 Maintain the cold chain and select "Booster" mode at least 6 hours before coming home with
groceries (if your model has it).
 Clean the refrigerator part at least once a month (see Care and cleaning)
 Keep home-made food in the refrigerator after first taking care to leave it to cool.
 Make sure that your appliance is set to the recommended temperatures shown below. The
temperatures for every compartment are recommended to optimise storing food and avoid
any waste.
