Control

5.1 Refrigerator compartment
The natural circulation of air in the refrigerator compart‐ment results in zones differing in temperature. It is coldest directly above the vegetable drawers and at the rear wall. It is warmest at the top front of the compartment and in the door.
5.1.1 Refrigerating food
Store perishable foods such as ready-to-eat meals, meat and sausages in the coldest area. Place butter and preserves in the top area and in the door. (see 1 Appli‐ ance at a glance)
Use reuseable plastic, metal, aluminium, glass containers and foil wrap to store food.
Always store raw meat and fish in clean, sealed containers on the bottom shelf of the refrigerator, to prevent them coming into contact with or dripping onto other foods.
Foods that easily absorb or give off smell or taste, as well as liquids, should be stored in sealed containers or covered.
Use the front area of the base shelf only to tempora‐rily set down refrigerated foods, for example while rear‐ranging or sorting the contents. Remember not to leave refrigerated foods here as they could shift to the back or tip over when you close the door.
Do not pack foods too closely together, as the air needs to circulate.

5.1.2 Setting the temperature
The temperature is adjustable clockwise between “off” and “max cold” (coldest temperature, greatest cooling capacity).
We recommend the middle control position, which ensures an average cold room temperature of approx. 5 °C.
An average temperature of about –18 °C is then set in the freezing compartment.
If frozen food is being stored and low freezing temperatures are to be ensured, it is recommended to adjust the tempera‐ture control setting from the middle position to “max cold” .
The “max cold” setting allows the coldest zone in the refrig‐erator to reach temperatures below 0 °C.
Turn temperature control Fig. 3 (1).
The temperature depends on the following factors:
– How often the door is opened
– How long the door is open for
– The room temperature of the installation site
– The type, temperature and amount of frozen items
If necessary, adjust the temperature with the control.
5.1.3 SuperCool function
This function ensures low temperatures in the freezer compartment.
Activating SuperCool function
At room temperatures of 15 °C or below, SuperCool is automatically activated. When SuperCool is activated, the SuperCool button lights up.
If you want to achieve lower temperatures in the freezer compartment, then you can also activate SuperCool manually:
Press the SuperCool (see Fig. 3) button.
The SuperCool button lights up.
Deactivating SuperCool function
SuperCool is automatically deactivated at room tempera‐tures of more than 15 °C. When SuperCool is deactivated, the SuperCool button does not light up.
If you have activated SuperCool manually, then SuperCool is automatically deactivated after 70 hours. However, you can also deactivate SuperCool manually at any time:
Press and hold the SuperCool (see Fig. 3) button for 3 seconds.

Note
At room temperatures of more than 15 °C, SuperCool is activated automatically if SuperCool has not been activated before. When SuperCool is automatically activated, the SuperCool button lights up. If SuperCool has been activated automatically, the function cannot be deactivated manually.
5.1.4 Shelves
Moving or removing shelves
The shelves are prevented from being pulled out acciden‐tally by pull out stops. Lift the shelf and pull forward a little.
Adjust the height of the shelf. To do this move the slots along the supports.
In order to remove the shelf fully, place it at a slant and pull out towards the front.

The food does not freeze onto the rear wall.
Dismantling shelves
The shelves can be dismantled for cleaning. 5.1.5 Door racks
Moving the storage rack
Remove storage rack according to illustration. 5.2 Freezer compartment
You can store frozen food, make ice cubes and freeze fresh food in the freezer compartment.
5.2.1 Freezing food
The rating plate indicates the maximum quantity of fresh food you can freeze within 24 hours (see 1 Appliance at a glance) under “Freezing capacity … kg/24h”.
Each drawer can hold a max. of 25 kg of frozen food.
The shelves can each be loaded with 35 kg of frozen food.
A vacuum is generated after the door is closed. After closing the door, wait for about 1 minute and then it opens more easily.

CAUTION
Risk of injury due to broken glass!
Bottles and cans containing drinks may burst when being frozen. This applies particularly to sparkling drinks.
Do not freeze bottles and cans containing drinks!
24 hours before freezing food, set the temperature to a mid to cold position
Switching SuperCool on: (see Activating SuperCool func‐tion) .
The freezer temperature will drop, and the appliance will operate at the maximum refrigerating capacity.
So that the food is rapidly frozen through to the core, do not exceed the following quantities per pack
– Fruit, vegetables up to 1 kg
– Meat up to 2.5 kg
Pack the food in portions in freezer bags, reusable plastic, metal or aluminium containers
Spread the food out in the bottom drawer and on the compartment bottom, and do not allow it to come into contact with food that is already frozen, to prevent this defrosting.
Reset the temperature controller 24 hours after inserting the food.
Reset the temperature 24 hours after storing the food.
When the room temperature is higher than 15 °C:
SuperCool is deactivated automatically after 70 hours.
However, you can also deactivate SuperCool manually at any time (see Deactivating SuperCool function) .

5.2.4  Drawers
To store frozen food directly on the shelves pull the drawer forward and lift it out. 5.2.5  Shelves
Moving shelves
To remove the shelf: lift up at the front and pull out.
To put the shelf back: simply push in as far as it will go. 5.2.6 VarioSpace
You can remove the shelves and drawers. This leaves more room for larger food items such as poultry, meat, large game and tall baked goods, which can be frozen whole before further preparation.  Each drawer can hold max. 25 kg of frozen food.
The shelves can each be loaded with 35 kg of frozen food.

Maintenance

6.1  Manual defrosting
Fridge compartment:
The fridge compartment defrosts automatically. The defrosted water is evaporated by the heat of the compressor. Water drops or a thin layer of frost or ice can form on the back wall; this is a completely normal part of the machine’s function.
Regularly clean the drain opening to allow the water to flow away (see 6.2 Cleaning the appliance) .
Freezer compartment:
A layer of frost or ice can build up in the freezer compart‐ment after a long period of operation.
The layer of frost or ice builds up faster if the appliance is opened often or if the food is warm when placed inside.
However, a thick layer of ice will increase the appliance‘s energy consumption. You should therefore defrost the appli‐ance regularly.
Thawing process:

WARNING
