Notes on disposal
❑Old appliances still have some residual
value. An environment-friendly method
of disposal will ensure that valuable raw
materials can be recovered and used
again.
Before you dispose of your old
appliance, make sure that it has been
rendered inoperable.
❑Your new appliance was protected by
suitable packaging while it was on its
way to you. All materials used for this
purpose are environment-friendly and
suitable for recycling. Please make a
contribution to protecting the
environment by disposing of the
packaging appropriately.
Up-to-date information concerning
options for disposing of your old
appliance and the packaging from the
new one can be obtained from your
retailer or local government office.

❑The Instructions for Use apply to several
versions of this appliance. Accordingly,
you may find descriptions of individual
features that do not apply to your

❑Please keep the operating and
installation instructions in a safe place;
this important documentation may also
be of use to a possible subsequent
owner.
❑Do not use the appliance if it is
damaged in any way.
❑Installation and connection of the
appliance should be performed
according to the instructions and

Appliance safety considerations
Important Information
❑If using hot air v, 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.
❑Do not clean the oven with steam or
high-pressure cleaners.
❑Do not insert a baking sheet at the
bottom of the oven, or cover the base of
the oven with aluminium foil, as this
would result in heat build up. Roasting
and baking times would change, and
the enamel would be damaged.
❑Never pour water directly into the hot
oven. Damage to the enamel could
result.
❑Dripping juices may leave spots on the
oven lining. Always place a baking tray
below to prevent this from happening.
❑Never stand or sit on the open oven
door.
❑The oven door must close properly.
Keep the door seal surfaces clean.
❑The appliance should only be used for
the preparation of food.
❑The surfaces of heating and cooking
appliances get hot during operation.
The interior oven walls and the heating
elements get extremely hot. Always
keep children away from the appliance.
❑Never leave the appliance unattended
when cooking with fat or oil. They can
catch fire if overheated.
❑Clean the oven regularly.
Fatty or oily remants could ignite when
the oven is switched on.
❑Make sure that the power cord does not
get caught in the hot oven door. The
plastic insulation could melt.
❑In the case of a defect, switch off (or
remove) the mains fuse in the building
electrical system.
❑Do not store combustible items in the
oven. They could ignite if the oven is
switched on accidentally.
Open the oven door
carefully.
Hot steam may escape.
