Dear customer,
Congratulations on your choice. Thank you for purchasing one of our
appliances. This practical, modern and functional appliance is manufactured
using materials of the highest quality which are subject to strict Quality
Control checks throughout the entire manufacturing process. The appliance
is meticulously tested to ensure that it meets your demands and produces
perfect cooking results.
Do not remove the appliance from its protective packaging until it is installed
in the unit.
Please read these instructions carefully before proceeding to install and use
the appliance. The information contained in these instructions is essential for
the correct operation of the appliance and, more importantly, for your safety.
The packaging of your appliance has been manufactured using only the
materials which are strictly necessary to guarantee efficient protection
during transport. These materials are 100% recyclable, thus reducing the
environmental impact. You can also contribute to caring for the environment,
by following the advice below:
- dispose of the packaging in the appropriate recycling bin,
- before you get rid of an old appliance, make sure you disable it. Contact
your local authority to find out the address of your nearest recycling centre
to dispose of your appliance,
- do not pour used oil down the sink. Collect it in a sealed container and
take it to an appropriate collection point or, failing that, place it in the rubbish
bin (it will end up in a controlled dump; this is probably not the best option,
but it will avoid contaminating ground water).
IMPORTANT:
In the unlikely event that the appliance should arrive damaged or not meet
your expectations in terms of quality, please inform us as soon as possible.
For the warranty to be valid, the appliance must not have been tampered
with, or used inappropriately.

protection
The hob is equipped with overheating protection to
protect the electronics. This switches all the burners
off in the event of overheating and the “power on/off”
indicators in all the burners and the main switch
flash.
Turn all control knobs to the 0 position. Wait until the
appliance has cooled down sufficiently and the power
on/off indicator for the main switch has gone out.
Now you can switch on the appliance as usual.

It is normal to hear a slight whistling noise while the
burner is operating.
When it is first used, it is normal for the burner to give off
odours; this does not pose any risk and does not indicate
a malfunction; they will disappear in time.
A few seconds after the burner is switched off, a sound
(thud) will be produced. This is not a fault - this means
that the safety device is no longer operating.
Keep the burner as clean as possible. If the ignition
sparkers are dirty they will not light properly. Clean them
periodically using a small non-wire brush. Bear in mind
that the ignition sparkers must not suffer any serious
impacts.
An orange-coloured flame is normal. This is caused by
the presence of dust in the atmosphere, spilt liquids, etc.
If the burner flames are accidentally blown out, switch off
the burner operating control knob and do not try to relight
it for at least one minute.

Food can be prepared in various ways in a wok: it can
be stewed, stir fried, cooked on a low heat, pan-fried,
or steamed. It could be said that woks serve as both
as a saucepan and a frying pan and, owing to their
shape and size, they can be used to cook quite large
ingredients.
When cooking with a wok, heat is diffused more
uniformly and gently; the intense heat which
accumulates means that food takes less time to
cook and also requires less oil, making it one of the
quickest and healthiest ways of cooking. Always
follow the manufacturer’s instructions when cooking
with a wok.
A wok is a cooking vessel originating in China; it is
a kind of deep, round, lightweight pan with handles
and a flat or concave base.

Precautions for use

energy and prevent cookware damage:
Use pans which are the right size for each burner.
Do not use damaged cookware, which does not sit
evenly on the hob. Pans may be overturned.
Only use a pan with thick, flat base.
Always place the cookware right over the burner, not
to one side. Otherwise it could be overturned.
Do not place large pans on the burners near the
controls. These may be damaged by the very high
temperatures.
Place the pans on the pan supports, never directly on
the burner.
Pans should be placed on the hob carefully.
Do not strike the hob and do not place excessive
weight on it.
Make sure that the pan supports and burner covers
are correctly positioned before using the appliance.

Cleaning and maintenance
Cleaning Once the appliance is cool, use a sponge to clean it with
soap and water.
After each use, clean the surface of the respective burner
parts once they have cooled down. If any bits are left
(overcooked food, drops of grease etc.), however few,
they will become stuck to the surface and more difficult
to remove later. The holes and grooves must be clean for
the flame to ignite properly.
The movement of some pans may leave metal residue on
the pan supports.
Clean the burners and pan supports using soapy water
and scrub with a non-wire brush.
Alternatively, the pan supports can be put in the
dishwasher. Use the dishwasher manufacturer's
recommended detergent. If the pan supports are very
dirty, they should be cleaned previously.
Do not put the burner caps in the dishwasher.
If the pan supports are fitted with rubber rests, ensure that
these are also cleaned. The rests may come loose and
the pan support may scratch the hob.
Always dry the burners and pan supports completely.
Water droplets or damp patches on the hob at the start
of cooking may damage the enamel.
After cleaning and drying the burners, make sure the
burner covers are correctly placed on the burner flame
diffuser.
Unsuitable products Never slide pans across the glass surface, as you may
scratch it. In addition, try not to drop heavy or sharp
objects on the glass. Never strike any part of the hob.
Do not use steam cleaners. This could damage the hob.
Never use abrasive products, steel scourers, sharp
implements, knives, etc. to remove bits of hardened food
from the hob.
If your hob is fitted with a glass or aluminium panel, never
use a knife, scraper or similar to clean the point where it
joins the metal.
Do not use knives, scrapers or similar implements to
clean the point where the glass meets the burner trims,
the metal frames or the glass/aluminium panels, if fitted.

Always clean off any liquid as soon as it is spilt: you
will save yourself any unnecessary effort.
Grains of sand that may come from cleaning fruits
and vegetables will scratch the glass surface.
Melted sugar, or foods which contain a lot of sugar
which may have spilt, should be cleaned off the
hotplate immediately, using the glass scraper.
Maintenance

Sometimes certain faults detected can be easily
resolved. Before calling the Technical Assistance
Service, bear in mind the following advice:

Geehrte Kundin, geehrter Kunde,
wir gratulieren zur Wahl des neuen Geräts und bedanken uns für das
entgegengebrachte Vertrauen. Dieses praktische, moderne und funktionelle
Gerät wird aus Materialien bester Qualität hergestellt, die während des
gesamten Produktionsprozesses strikten Qualitätskontrollen unterliegen und
genauestens geprüft werden, um Ihre Anforderungen an einen perfekten
Kochvorgang zu erfüllen.
Belassen Sie das Gerät bis zum Einbau in der Schutzhülle.
Wir bitten Sie, diese Anweisungen vor dem Einbau oder der Benutzung
des Geräts durchzulesen. Die darin enthaltenen Informationen sind für den
korrekten Betrieb und - wichtiger noch - für Ihre eigene Sicherheit sehr
wichtig.
Die Verpackung Ihres Geräts besteht aus Materialien, die notwendig
sind, um einen wirksamen Schutz beim Transport zu garantieren. Diese
Materialien sind vollständig wiederverwendbar und verringern damit
die Umweltbelastung. Wie wir können auch Sie einen Beitrag zum
Umweltschutz leisten, indem Sie folgende Ratschläge beachten:
- Entsorgen Sie die Verpackung in einer Tonne für recyclingfähige
Materialien.
- Machen Sie ein Altgerät vor der Entsorgung unbrauchbar. Informieren
Sie sich bei Ihrer örtlichen Verwaltung über die Adresse des nächsten
Wertstoffhofs und liefern Sie Ihr Gerät dort ab.
- Schütten Sie verwendetes Bratfett oder Öl nicht durch das Spülbecken.
Sammeln Sie das Öl in einem verschließbaren Gefäß und geben Sie es bei
einer Sammelstelle ab oder werfen Sie es, wenn dies nicht möglich ist, in die
Mülltonne (so gelangt es auf eine kontrollierte Mülldeponie; vermutlich nicht
die beste Lösung, doch wird so kein Wasser verschmutzt).
WICHTIG:
Falls das Gerät wider Erwarten Schäden aufweisen oder Ihre
Qualitätsanforderungen nicht erfüllen sollte, setzen Sie uns davon so schnell
wie möglich in Kenntnis. Zur gültigen Einlösung der Garantie darf das Gerät
nicht unbefugt manipuliert bzw. benutzt worden sein.
