Operation modes
Fan grill
The upper heater and the fan are activated simultaneously. It
is appropriate for grilling and browning large pieces of meat,
poultry or gratins on one shelf level.
Half grill
The inner heater is activated. This mode is appropriate for
grilling smaller quantities of toasted sandwiches, sausages
or bread.
Oven lighting
There is one interior lighting lamp: on the upper part of the
back wall. Oven lighting can be selected independently. With
all other modes of operation, the oven lighting is turned on
automatically when the operation mode is selected.
Full grill
The inner and the outer heaters are activated simultaneously.
This operation mode is appropriate for cooking smaller pieces
of meat, such as steaks, roasts, chops, ribs, etc.
Upper / lower heater
The heaters on the upper and lower side of the oven radiate
uniformly and evenly into the oven interior. Pastries, cakes
and meat can be cooked on one shelf level only.

11
Lower heater/ Steam clean
The bottom heater is activated. Select this mode when you
wish to cook the bottom side of the dish more thoroughly
(e.g. for deep pastry with fruit lling). Set the temperature with
the temperature selection dial. The lower heater can also be
used for cleaning the oven, for instructions please see the
“Cleaning and maintenance” section on page 29.
Lower heater and fan
The lower heater and the fan operate simultaneously. Used
for baking sweet bread dough and preserving fruit and
vegetables. Use the rst shelf position from the bottom and
shallow rather than deep baking trays.
Defrosting
The air is circulated without any heater being turned on. Only
the fan is in operation. This is used for defrosting frozen food.
Convection
The back heater and the fan operate simultaneously in order
for the hot air to circulate constantly. This mode is appropriate
for roasting meat and making pastry on several shelves
simultaneously. Cooking temperature should be set lower
than conventional operation.
Convection and lower heater
The back heater, the fan and the lower heater operate
simultaneously. This is suitable for making pizza, pastries,
fruit cakes or baked cheesecakes.

12
Note

Shelf levels
• Accessories (wire shelf, shallow baking tray and the
deep baking tray) can be inserted into the oven at four
levels.
• Please note that the shelf levels are always referred
to by consecutive numbers starting from the bottom
(particular shelf levels are described in the cooking
tables).
• The wire shelf and the trays should always be inserted
into the leading slot formed by adjacent wire proles of
the wire guides.
Wire shelf
Food is placed directly on wire shelf or in a container on wire
shelf.
A safety stop is tted on the wire shelf and on the
guides. To pull out the wire shelf, lift it slightly
when it hits the stop.
Shallow baking tray
This is used for baking pastry, small cakes and biscuits.
Deep baking tray
This is used for roasting meat and as a drip tray.
The deep baking tray is used only as a drip
tray when using the grill functions, the deep
tray should not be inserted into the fourth shelf
position.
Accessories

18
• To insert the wire shelf, deep baking tray, or shallow baking tray, rst pull out the telescopic
guides of the desired level.
• Place the wire shelf, deep baking tray, or shallow baking tray on the pull-out guides and
push it into the oven. Close the oven door only when the telescopic guides have been fully
retracted.
The fan on the oven back plate is covered by a catalytic
layer that can be installed or removed only by an authorised
service technician.

19
Food preparation
Baking and cooking
• Use the , or . mode of operation.
Instructions
• Always observe the instructions on the shelf / shelf position, temperature, and cooking time
indicated in the baking table. The values indicated in the table are dened and checked
especially for this particular oven.
• If the baking table does not specically mention a particular food, refer to the information for
a similar type of food.
Cooking /baking with upper and lower heater
• Cook /Bake at one level only.
• Upper / lower heater combination is suitable for cooking
various types of pastry, bread, and meat.
• Use dark-coloured baking trays. Light-coloured trays reect
the heat, which leads to poorer cooking (browning) results.
Always place your own cooking containers on the wire
shelf. If you are using the supplied baking tray, remove the
wire shelf.
• Preheating will shorten the cooking time. Place the dish
into the oven only when the selected temperature has been
reached, i.e. When the heater operation symbol goes off
for the rst time.
Cooking / baking with convection
Cooking / baking with convection is useful when you wish
to bake on several shelves simultaneously. Preheating
is recommended. This mode is also appropriate for large
sponge cakes and fruit cakes (in this case, bake on a single
level only).
• The temperature is normally set lower than when baking with
the upper/lower heater combination (see baking table).
• When baking with several baking trays simultaneously,
baking time for each tray can vary. You may have to
remove one of the trays earlier (normally, this would be the
uppermost tray).
• When using several baking trays simultaneously, there
may be a signicant amount of vapour in the oven,
resulting in condensation on the oven door.

20
Is the cake cooked?
At the end of the cooking time, insert a metal skewer into the highest point of the cake and
then withdraw it. If the batter does not stick to the metal skewer, the cake is cooked.
The sponge cake has collapsed after I take it out of the oven
Check the recipe. Check the instructions relating to mixing time. Ensure the oven door is ot
opened during cooking.
The pastry is too light-coloured
A dark-coloured baking tray cooks dishes faster and browns foods more than lighter coloured
pans. Place the tray one shelf position lower, or turn on the lower heater towards the end of
the cooking process.
Pastries with a moist lling (e.g. deep lled pie) is not cooked
Reduce the temperature and extend the cooking time.
Notes on the baking chart:
• Two values are indicated for temperature, lower and upper. Initially, set the lower
temperature; if the pastry is not brown enough, increase the temperature.
• Cooking times are a guideline only.
• The value printed in bold in the temperature table indicates the most appropriate operating
mode for a particular type of food.
• Always preheat the oven.
• When using baking paper, make sure it is resistant to high temperature.
