Before installation
Transport damage Check the appliance after unpacking it. Do not
connect the appliance if it has been damaged in
transport.
Electrical connection The cooker may only be connected by an approved
specialist. Losses resulting from damage caused by
incorrect connection will invalidate warranty claimes.
Safety information This appliance is intended for domestic use only.
Only use the cooker for food preparation.
Hot oven Open the oven door carefully. Hot steam may escape.
Never touch the internal surfaces of the oven or the
heating elements. There is a risk of burning.
Children must be kept at a safe distance from the
appliance.
Never store combustible items in the oven.
Risk of fire. Never place flammable objects onto the
hot plates. Fire hazard!
Never place cables of electronic devices onto the hot
plates.
Never clamp leads of electrical appliances in the hot
oven door. The insulation on the leads could melt.
There is a risk of short-circuiting.
Caution: The extension rails heat up during oven
operation. Use special care to avoid burns when
extending the rails.
Remove all packaging remnants, e.g. polystyrene
parts, from the oven.
Repairs Incorrectly done repairs are dangerous. There is a

Reasons for
damage
Baking tray, aluminium foil Do not place the baking tray on the oven floor.
or dishes on the oven floor Do not cover it with aluminium foil.
Do not place dishes on the oven floor.
This will cause heat accumulation. The baking and
roasting times will no longer be correct and the
enamel will be damaged.
Slide-in accessories To avoid damage, insert slide-in accessories
carefully.
Baking paper If using hot air functions *, do not place
greaseproof paper loosely in the oven (e.g. when
heating the oven).
The hot-air fan could draw in the paper which may
damage the heater and fan.
Water in the oven Never pour water directly into a hot oven.
This could damage the enamel.
Fruit juice When baking very moist fruit cakes, do not put too
much on the baking sheet. Fruit juice dripping from
the baking sheet leaves stains that cannot be
removed.
It is recommended that you use the deeper universal
pan.
Cooling with the oven door Only leave the oven to cool with the door closed. Do
not allow anything to become trapped in the oven
door. Even if you only leave the oven door open
slightly, the fronts of adjacent units may become
damaged over time.
Very dirty oven seal If the oven seal is very dirty, the oven door will no
longer close properly when the oven is in use.
The fronts of adjacent units could be damaged.
Keep the oven seal clean.
Using the oven door as a Do not stand or sit on the oven door.

Note:
The baking tray or universal pan may distort while the oven is operating. This is cau-
sed by major temperature differences on the utensil. These differences may occur if
only one part of the utensil was covered or if deep-frozen food, e.g. pizza, was placed
on the utensil.
The distortion will subside again during baking, roasting or grilling.

Description of Oven Features
Circotherm A fan system located in the rear oven wall circulates
the circotherm in the oven, achieving an especially
effective heat transfer to the food being baked or
roasted.
Advantages:
–Simultaneous baking and roasting possible on up
to 2 levels
–low soiling of oven interior
–shorter preheating times
–low oven temperatures
Surface grilling The food being prepared is exposed to heat radiation
from the heating element at the top of the oven
cavity.
–Particularly effective with flat, small cuts of meat,
i.e., steaks, sausages, fish, vegetables and toast.
Large area grill Advantages:
–the entire grilling surface heats up
–especially useful with large amounts of food
Small area grill Advantages:
–only the centre area of the grilling surface heats
up
–especially useful with small amounts of food
–energy-saving operation
Circo-roasting With Circo-roasting, the air circulating fan and the
grilling elements are activated in alternataly.
The heat generated by the grilling element is evenly
distributed in the oven cavity.
Advantage:
–Particularly effective with poultry.

Bread baking Bread baking with hot air function.
Adjustable 180 – 220° C.
Dough proving The dough proving function provides ideal conditions
inside the oven for getting yeast dough to rise.
Temperature: 35 – 38° C
Humidity: 75 – 100%
Advantages:
–rapid and uniform increase in volume of dough
–dough does not dry out
–dough does not form a skin which means that it
very easy to process and work into the required
shape
–exclusion of unfavourable external influences
(e.g. draughts).
–yoghurt can be made.
AquaCleanse The oven cleaning function featured in your oven is
(oven cleaning system) intended to help you keep your oven neat and tidy.
An amount of cleaning solution is vaporised
automatically. The combined effects of heat and
steam soften the soil deposits on the oven wall
enamel and facilitate their removal. For more
information on this function, see the section on
”Cleaning and Care” later in this booklet.
Advantages:
–takes the toil out of oven cleaning
–protects the enamel on interior surfaces
–constitutes an environmentally friendly cleaning

Baking
Using baking tins Always place baking tins in the centre of the
baking wire shelf.
We recommend dark metallic baking tins.
Notes Light coloured baking tins made from thin-wall
materials lead to longer baking times and uneven
browning of the cake.
You can influence the degree of browning by
changing the temperature setting.
If a cake collapses after removing it from the oven,
consider using a longer baking time, or use a slightly
lower temperature setting.
Using tinplate baking tins *Circotherm Shelf position 1
If the cake bottom gets too dark:
Check the shelf position. Shorten the baking time,
and possibly use a lower baking temperature.
If the cake bottom stays too light:
Check the shelf position. Increase the baking time,
select a lower temperature, or use a dark metal
baking tin.
Do not place baking tins or high cakes too close
to the rear oven wall.

you can switch off the oven 5-10 minutes before the
full baking time has elapsed.
