How to use the vitroceramic hob
The ceramic surface of the hob allows a
fast transmission of heat in the vertical
direction, from the heating elements
underneath the ceramic glass to the pans
sat on it.
The heat does not spread in the horizontal
direction, so that the glass stays “cool” at
only a few centimeters from the cooking
plate.
The 5 cooking plates are shown by dark
disks on the ceramic surface.

Cooking hints
– To reduce the cooking time, you can turn the control knob to the max when you switch
the plate on.
After a short time you set the control knob to the required position for the cooking.
– You should use pots and pans with flat bases.
The diameter of the pan should match that of the cooking plate (or be slightly bigger) to
make the most of the energy.
– Since the cooking surface stays hot for a certain time after the plate has been switched off,
you can switch it off minutes before the end of the cooking.
The residual heat of the hob will terminate the cooking.
– To save electricity, use lids whenever possible.

Cleaning the hob
Before you begin cleaning make sure
that the appliance is switched off.
Remove spillages and other types of
incrustations by using a scraper.
Dust or food particles can be removed
with a damp cloth.
If you use a detergent, please make sure
that it is not abrasive or scouring. Abrasive
or scouring powders can damage the
glass surface of the hob.
All traces of the cleaner have to be
removed with a damp cloth.
It is highly recommended to keep off the
hob any article which can melt: plastic,
aluminium foil, sugar, sugar syrup mixtures
etc.
If any of these products has melted on the
ceramic surface, you should remove it
immediately (while the surface is still hot)
by using a scraper to avoid any
permanent damage to the surface of the
hob.
Avoid using any knife or sharp utensil
since these can damage the ceramic.
Do not use steel wool or an abrasive
sponge which could scratch the surface
in an irrepairable way.
ATTENTION: MOST IMPORTANT!
If cleaning the glass ceramic hob using
a special tool (i.e. scraper) take extra
care to avoid damage to the seal at the
edges of the glass ceramic surface.
Safety hints:
– Before you switch the hob on, make sure
you know which knob controls the
required cooking plate. We advise you to
sit the pan over the cooking plate before
switching it on. Remove the pan after you
have switched the cooking plate off.
– Do not use pots and pans with rough
bases (pay attention to cookware made
of cast-iron). Rough bases can damage
the glass surface of the hob (scratches).
Make sure that the pan bottom is dry and
clean.
– Pots with aluminium bottoms may leave
silver streaks or spots on the hob.
– Pan handles should never stand out
beyond the kitchen worktop, as there is a
great danger of knocking the pan over.
This will also ensure that children cannot
reach them.
– Do not use the cooker if the glass surface
is broken or cracked in any way. Please
disconnect the appliance from the mains
and call the After-Sales Service.
– Do not lean over the cooking plate when
in use.
– Do not lay cooking foil, aluminium foil or
plastic materials on the ceramic surface
when it is hot.
– Remember that the surface remains hot for
a long time (about 30 min.) after the
cooking plate has been switched off.
Keep children well out of reach
– Do not use the glass surface for storage.
– Follow the cleaning instructions carefully.

How to use the Multifunction oven
OPERATING PRINCIPLES
Heating and cooking in the MULTI-FUNCTION oven are obtained in the following
ways:
a. by normal convection
The heat is produced by the upper and lower heating elements.
b. by forced convection
A fan sucks in the air contained in the oven muffle, which sends it through the
circular heating element and then sends it back through the muffle. Before the
hot air is sucked back again by the fan to repeat the described cycle, it envelops
the food in the oven, provoking a complete and rapid cooking.
It is possible to cook several dishes simultaneously.
c. by semi-forced convection
The heat produced by the upper and lower heating elements is distributed
throughout the oven by the fan.
d. by radiation
The heat is radiated by the infra red grill element.
e. by radiation and ventilation
The irradiated heat from the infra red grill element is distributed throughout the
oven by the fan.
Please note: This appliance incorporates a safety cooling fan which you will hear
operating whenever the oven or grill are in use. This fan is to reduce the external
temperature of the appliance and cool the internal components.

Fig. 21 Fig. 22
OVEN LIGHT
By setting the knob to this position, only the oven light comes on (15 W).
It remains on in all the cooking modes.
TRADITIONAL CONVECTION COOKING
The upper and lower heating elements come on. The heat is dispersed by natural
convection and the temperature must be set to between 50° and 225°C via the
thermostat knob.
The oven must be preheated before cooking.
Recommended for:
Food that requires the same degree of cooking both inside and out, for example
roasts, spare pork ribs, meringues etc.
18

HOT AIR COOKING
The circular element and fan come on. The heat is dispersed by forced convection
and the temperature can be regulated to between 50° and 225°C via the
thermostat knob. The oven does not require preheating.
Recommended for:
Food which has to be well-cooked outside and soft or rosy inside, for example
lasagne, lamb, roast beef, whole fish etc.
DEFROSTING FROZEN FOODS
Only the oven fan comes on. Use with the thermostat knob set to “●” - other positions
have no effect. The food is thawed by ventilation without heating.
Recommended for:
Quick thawing of frozen foods; one kg requires approximately 1 hour.
Thawing times vary according to the quantity and type of food to be thawed.
GRILLING
The infrared grill element comes on. The heat is dispersed by radiation.
Set the thermostat knob to between 50° and 200°C.
Always grill with the oven door closed.
For cooking hints, see the chapter “USE OF THE GRILL”.
Recommended for:
Intense grilling, browning, cooking au gratin and toasting etc.
Do not grill for longer than 30 minutes at any one time on full heat (200°C).
Caution: the oven door becomes very hot during operation.
Keep children well out of reach.
19

VENTILATED GRILL COOKING
The infrared grill element and the fan come on. The heat is dispersed mainly by
radiation and the fan then distributes it all over the oven.
Use with the door closed. The temperature can be regulated via the
thermostat knob to between 50° and 175° max.
The oven must be preheated for approximately 5 minutes. For cooking hints, see
the chapter “GRILLING AND COOKING AU GRATIN.
Recommended for:
Grilling where quick browning on the outside is required to keep the juices in.
For example: veal steaks, chops, hamburgers etc.
Do not grill for longer than 30 minutes at any one time on full heat (175°C).
Caution: the oven door becomes very hot during operation.
Keep children well out of reach.
MAINTAINING TEMPERATURE AFTER COOKING OR
SLOWLY HEATING FOODS
The upper heating element, the circular element and the fan come on.
The heat is dispersed by forced convection with greater intensity in the upper part.
The temperature can be set to between 50° and 140°C via the thermostat knob.
Recommended for:
Keeping food warm after any type of cooking. Slow heating of cooked food.
CONVECTION COOKING WITH VENTILATION
The upper and lower heating elements come on and the fan.
The heat coming from above and below is dispersed by convection with ventilation.
The temperature can be set to between 50° and 225°C via the thermostat knob.
Recommended for:
Voluminous dishes and large quantities which require the same degree of cooking
both inside and out, for example rolled roasts, turkey, roast legs, cakes etc.
