Control

Refrigerator compartment

The natural circulation of air in the refrigerator compartment 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.

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 Appliance 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 temporarily set down refrigerated foods, for example while rearranging 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.

Setting the temperature
The temperature can be set between 1 (warmest temperature, minimum cooling performance) and 7 (coldest temperature, maximum cooling performance).
The middle control setting is recommended, then a middle temperature of approx.5 °C is established in the refrigerator compartment.
An average temperature of approx. –18 °C is then established in the freezer compartment.
To ensure ideal temperatures for storing frozen foods, a setting of “4” to “7” on the temperature controller is recommended.
Selecting “7” makes it possible to achieve temperatures under 0 °C in the coldest part of the fridge compartment.

Turn the temperature control Fig. 3 (1).

The temperature depends on the following factors:

• the door opening frequency
• how long the door is open for
• the room temperature at the site where the appliance is installed
• the type, temperature and quantity of frozen food

 Adjust the temperature as needed, using the control.

CoolPlus function
At low room temperatures of 15 °C or lower:
Press the Cool-Plus switch Fig. 3 (2).
The deep temperatures in the freezer compartment are ensured.

Once the room temperature is again higher than 15 °C :
 Deactivate the Cool-Plus Fig. 3 (2) switch manually.

Note
At normal room temperatures, in excess of 15 °C, the CoolPlus switch should be turned off, as it is not required.

Shelves
Moving or removing shelves
The shelves are prevented from being pulled out accidentally 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.

Do not freeze bottles and cans containing drinks!
24 hours before freezing food, set the temperature to a mid to cold position
Switch on Cool-Plus: Press theCool-Plus Fig. 3 (2) button.
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
Put the food into the freezer compartment so that it is in contact with the floor or the side walls.
Distribute the food over the shelf and do not let it touch goods that are already frozen, in case this causes them to defrost.
Reset the temperature 24 hours after storing the food.
When the room temperature is higher than 15 °C:
 Switch off Cool-Plus: Press theCool-Plus Fig. 3 (2) button.

Storage life

The values indicated for storage life are standard ones.

Food once thawed should be re-frozen only in exceptional cases.

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.

Maintenance

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 compartment 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 appliance regularly.

Thawing process:
