CLEANING AND MAINTENANCE
A few cooking tips
Use only saucepans and frying pans with a sturdy, preferably thick bottom. This is particularly important when
preparing food requiring high cooking temperatures, such as fried foods. If the bottom of the pan is not perfectly
flat, the food takes longer to cook and uses up more energy. The best heat transfer is obtained when the
saucepan and burner are the same size.
You can also use Pyrex and porcelain pans on the burners, providing the bottom of the pan is smooth. Refer to the
instructions of the pan manufacturer on this point.
Any spillages from the pans should be wiped away immediately.
Important notes
Warning: the burner surface becomes red hot when in use, so it is always advisable to keep children well away
from the cook top.
Avoid dropping any hard object on the cook top surface. In some conditions, the material is sensitive to
mechanical loading. The shock of a sharp or pointed object can damage the cooking surface. In the event of any
breakage, cracking or other damage being accidentally caused to the ceramic top, it is essential to stop using the
cook top immediately and contact customer care.
Ceramic glass cook tops must never be used as a work surface. Do not us aluminum pan. Do not prepare food
wrapped in aluminium foil or packaged in plastic. Never use the burner without a saucepan on it. Never place
flammable, explosive or deformable objects in the vicinity of the cook top.
Fats and oils can catch fire if they are overheated: that is why foods requiring the use of fat or oil, e.g. French fries,
must always be supervised while they are cooking.
Moreover, it is essential to make sure that the power cords and plugs of any other domestic appliances attached to
sockets near the cook top can never come into contact with the hot cook top surfaces. No part of the power supply
cable must reach an ambient temperature which is over 50°c.
If damaged, the cable must be replaced with one supplied by the technical assistance service. If the glass surface
breaks, unplug the device from the mains supply in order to avoid getting an electric shock.
The cook top must never be cleaned with steam or other such cleaning devices.
It is essential to clean the cook top - once it has cooled down - every time it has been used. Even the smallest food
scraps would burn the next time it is used. Use only the recommended detergents. Wire wool, abrasive pads and
powders will cause scratching. Oven-cleaning products are unsuitable because they are corrosive.
Mild soiling can be removed with the aid of a damp cloth or with hot soda. Any traces of detergent must be
removed with cold water and the surfaces must then be accurately dried. Any signs of water that cannot be
removed with boiling water can be eliminated with vinegar and lemon juice, or with a scale-remover fluid. If any of
these detergents comes into contact with the cook top frame, it must be cleaned off immediately with a wet cloth,
to avoid damaging the seal.
Any tenacious dirt can easily be removed with the aid of a glass scraper. The scraper handle must not be made of
plastic because it could become stuck to the hot surfaces. Pay attention while using to scraper: it can cause injury.
Sugar and foods containing caramelized sugar must be removed immediately from the hot burner.
