Ambient temperature and ventilation

Ambient temperature

The appliance is designed for a specific climate class. Depending on the climate class, the appliance can be operated at the following temperatures.

The climate class can be found on the rating plate. Fig. .

Climate class Permitted ambient

temperature

SN +10 °C to 32 °C N +16 °C to 32 °C ST +16 °C to 38 °C T +16 °C to 43 °C

Note

The appliance is fully functional within the room temperature limits of the indicated climatic class. If an appliance of climatic class SN is operated at colder room temperatures, the appliance will not be damaged up to a temperature of +5 °C.

Room temperature switch

If the room temperature drops below +16 °C, the freezer compartment of appliances belonging to climate class SN may become too warm. In an extreme case the frozen food may thaw. To prevent this from happening, switch on the room temperature switch. As a result, the refrigeration unit operates more frequently. The appliance can now be operated at a room temperature of +10 °C to +16 °C.

To switch on, press the room temperature switch, Fig. 2/B.

Red mark becomes visible. To save energy, switch off the room

temperature switch as soon as the room temperature exceeds +16 °C.

Ventilation

Fig. 1/6 The refrigeration unit is ventilated only

via the ventilation grille in the base. Never cover the ventilation grille or place anything in front of it. Otherwise the refrigeration unit must work harder, increasing the power consumption.

Installation location

Install the appliance in a dry, well ventilated room. The installation location should neither be exposed to direct sunlight nor near a heat source, e.g. a cooker, radiator, etc. If installation next to a heat source is unavoidable, use a suitable insulating plate or observe the following minimum distances to a heat source:

■ 3 cm to electric or gas cookers.

■ 30 cm to an oil or coal-fired cooker.

Undercounter

An attachment under certain worktops, e.g. stone, glass or stainless steel, is frequently not possible. You can order accessories from customer service for installation on the side walls.

Connecting the appliance

After installing the appliance, wait at least 1 hour until the appliance is switched on. During transportation the oil in the compressor may have flowed into the refrigeration system.

Before switching on the appliance for the first time, clean the interior of the appliance (see chapter “Cleaning the appliance”).

Electrical connection

The socket must be near the appliance and also freely accessible following installation of the appliance.

The appliance complies with the protection class I. Connect the appliance to 220–240 V/50 Hz alternating current via a correctly installed socket with protective conductor. The socket must be fused with a 10 to 16 A fuse.

For appliances operated in nonEuropean countries, check whether the stated voltage and current type match the values of your mains supply match the values of the mains supply. This information can be found on the rating plate. Fig. .

Getting to know your appliance

Please fold out the illustrated last page. These operating instructions refer to several models.

The features of the models may vary. The diagrams may differ. Fig. 1

1Light switch 2 Temperature controller/light 3 Glass shelf in the refrigerator

compartment 4 Pull-out container 5 Vegetable container 6 Ventilation opening 7 Shelf for butter and cheese 8 Egg rack 9 Shelf for large bottles

A Freezer section B Refrigerator compartment

Switching the appliance on

Turn temperature controller, Fig. 2/A, from position “0”. The appliance begins to cool. Light is switched on when the door is open.

Operating tips

The refrigerator compartment temperature rises:

■ if the appliance door is opened

frequently,

■ if large quantities of food are placed

in the refrigerator compartment,

■ if the ambient temperature is high.

Setting the temperature

Turn temperature controller, Fig. 2/A, to the required setting.

When the controller is at a medium setting, the temperature drops to approx. +4 °C in the coldest zone. Fig. 3.

Higher settings lower the temperature in the refrigerator and freezer compartments.

We recommend:

■ Perishable food should not be stored

above +4 °C.

■ Low setting for short-term storage of

food (energy-saving mode).

■ Medium setting for long-term storage

of food.

■ Select a higher setting only

temporarily, when the door is frequently opened or large quantities are placed in the refrigerator compartment.

Refrigeration capacity

The temperature in the refrigerator compartment may rise temporarily if large amounts of food or a lot of drinks are placed inside.

Therefore the temperature controller should be set to a higher setting for approx. 7 hours.

Freezer compartment

The temperature in the freezer compartment depends on the temperature in the refrigerator compartment.

Usable capacity

Information on the usable capacity can be found inside your appliance on the rating plate. Fig. .

Refrigerator compartment

The refrigerator compartment is the ideal storage location for ready meals, cakes and pastries, preserved food, condensed milk, hard cheese, fruit and vegetables sensitive to cold as well as tropical fruit.

Note when loading products

Wrap or cover food before placing in the appliance. This will retain the aroma, colour and freshness of the food. In addition, flavours will not be transferred between foods and the plastic parts will not become discoloured.

Note

Avoid contact between food and rear panel. Otherwise the air circulation will be impaired.

Food or packaging could freeze to the rear panel.

Note the chill zones in the refrigerator compartment!

The air circulation in the refrigerator compartment creates different chill zones:

■ Coldest zone is in the pull-out

container. Fig. 3

Note

Store perishable food (e.g. fish, sausage, meat) in the coldest zones.

■ Warmest zone is at the very top of

the door.

Note

Store e.g. cheese and butter in the warmest zone. When served, the cheese will not have lost its flavour and the butter will be easy to spread.

The freezer compartment

Using the freezer compartment

■ To store deep-frozen food.

■ To make ice cubes.

■ To freeze small quantities of food.

Note

Ensure that the freezer compartment door has been closed properly. If the door is open, the frozen food will thaw. The freezer compartment will become covered in thick ice. Also: waste of energy due to high power consumption!

Max. freezing capacity

Information about the max. freezing capacity within 24 hours can be found on the rating plate. Fig. .

Freezing and storing food

Purchasing frozen food

■ Packaging must not be damaged.

■ Use by the “use by” date.

■ Temperature in the supermarket

freezer must be -18 °C or lower.

■ If possible, transport deep-frozen food

in a cool bag and place quickly in the freezer compartment.

Freezing fresh food

Freeze fresh and undamaged food only. To retain the best possible nutritional

value, flavour and colour, vegetables should be blanched before freezing. Aubergines, peppers, zucchini and asparagus do not require blanching.

Literature on freezing and blanching can be found in bookshops.

Note

Keep food which is to be frozen away from food which is already frozen.

■ The following foods are suitable for

freezing: Cakes and pastries, fish and seafood, meat, game, poultry, vegetables, fruit, herbs, eggs without shells, dairy products such as cheese, butter and quark, ready meals and leftovers such as soups, stews, cooked meat and fish, potato dishes, soufflés and desserts.

■ The following foods are not suitable

for freezing: Types of vegetables, which are usually consumed raw, such as lettuce or radishes, eggs in shells, grapes, whole apples, pears and peaches, hard-boiled eggs, yoghurt, soured milk, sour cream, crème fraîche and mayonnaise.

Note

When freezing fresh food, the refrigeration unit runs for longer. As a result, the refrigerator compartment temperature may drop too low. Increase the temperature in the refrigerator compartment.

Packing frozen food

To prevent food from losing its flavour or drying out, place in airtight containers.

1. Place food in packaging.

2. Remove air.

3. Seal the wrapping.

4. Label packaging with contents

and date of freezing.

Suitable packaging:

Plastic film, tubular film made of polyethylene, aluminium foil, freezer containers. These products are available from specialist outlets.

Unsuitable packaging:

Wrapping paper, greaseproof paper, cellophane, bin liners and used shopping bags.

Items suitable for sealing packaged food:

Rubber bands, plastic clips, string, coldresistant adhesive tape, etc.

Bags and tubular film made of polyethylene can be sealed with a film heat sealer.

Shelf life of frozen food

Storage duration depends on the type of food.

At a temperature of -18 °C:

■ Fish, sausage, ready meals and cakes

and pastries: up to 6 months

■ Cheese, poultry and meat:

up to 8 months

■ Vegetables and fruit:

up to 12 months

Thawing frozen food

Depending on the type and application, select one of the following options:

■ at room temperature

■ in the refrigerator

■ in an electric oven, with/without fan

assisted hot-air

■ in the microwave

Vegetable container with cover

Disconnecting the appliance

If you do not use the appliance for a prolonged period:

1. Switch off the appliance.

2. Pull out mains plug or switch off fuse.

3. Clean the appliance.

4. Leave the appliance door open.

Defrosting

Refrigerator compartment defrosts fully automatically

While the refrigerating unit is running, beads of condensation or hoarfrost form at the back of the refrigerator compartment. This is quite normal. It is not necessary to wipe off the condensation or frost. The rear panel defrosts automatically. The condensation runs into the condensation channel, Fig. +. and is conveyed to the refrigerating unit where it evaporates.

Note

Keep the condensation channel and drainage hole clean, so that the condensation can run out.

Freezer compartment

The freezer compartment does not defrost automatically. A layer of hoarfrost in the freezer compartment will impair refrigeration of the frozen food and increase power consumption. Regularly defrost the freezer compartment.

ã=Caution

Do not scrape off hoarfrost or ice with a knife or pointed object. You could damage the refrigerant tubes. Leaking refrigerant may ignite or cause eye injuries.

Proceed as follows: Note

Approx. 4 hours before defrosting the appliance, turn the temperature controller to the highest setting so that the food drops to a very low temperature and can therefore be stored at room temperature for a longer period.

1. Remove the frozen food and place

temporarily in a cool location.

2. Switch the appliance off.

3. Pull out the mains plug or remove

the fuse.

4. To accelerate the defrosting process,

place a pan of hot water on a trivet in the freezer compartment.

5. Wipe up condensation with a cloth

or sponge.

6. Wipe dry the freezer compartment.

7. Switch the appliance on again.

8. Put the frozen food back in the freezer

compartment.

Cleaning the appliance

ã=Caution

■ Do not use abrasive, chloride or acidic

cleaning agents or solvents.

■ Do not use scouring or abrasive

sponges. The metallic surfaces could corrode.

■ Never clean shelves and containers

in the dishwasher. The parts may become deformed!

Proceed as follows:

1. Before cleaning: Switch the appliance off.

2. Pull out the mains plug or switch off the fuse.

3. Take out the frozen food and store in a cool location.

4. Clean the appliance with a soft cloth, lukewarm water and a little pH neutral washing-up liquid. The rinsing water must not run into the light.
