USE OF COOKING HOB
3
3
Fig. 3.2
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 set on it.
The heat does not spread in the horizon-
tal direction, so that the glass stays
“cool” at only a few centimeters from the
cooking plate.
The 5 cooking zones are shown by
painted disks on the ceramic surface.
3 CIRCUI S RADIAN ZONES
Incorporating 3 heating elements (fig.
3.2) you can control and light up all
together or separately by a 6 position
switch (fig. 3.1).
Reaches the working temperature in a
very short time.
Fig. 3.1
IMPORTA T OTE:
The heating elements incorporate a
thermolimiter that switches ON/OFF the
element in all settings to protect any
overheating of the ceramic glass.
The use of incorrect pans and/or wrong
pan positioning will cause the tempera-
ture limiter to operate more frequently,
resulting in a reduction of cooking per-
formance.

9
DOUBLE AND OVAL RADIAN ZONES
The heating element is formed of a coil
of resistant material which reaches the
working temperature quickly.
Operation of the cooking zone is con-
trolled by a continuous energy regulator
from 1 to 12 (maximum temperature) (fig.
3.3).
To turn on both zones of the double
element, turn the double element knob
fully clockwise to the position .
To reduce the heat of the full double ele-
ment, turn its knob anticlockwise to set-
ting 12 or lower. Adjust the heat during
cooking as necessary.
ote: if you leave the knob at the
position, the full double element will
remain at the highest heat setting.
To return to using only the inner zone
of the double element, first turn the
knob to the o(off) position (you should
feel a click) and then clockwise to a set-
ting from 1 to 12.

RESIDUAL HEA INDICA OR
The hob also features 5 warning lamps
which are wired to the corresponding
plate.
When the temperature of a cooking plate
is over 60°C, the relevant warning lamp
is also lit-up to warn of heat on the sur-
face of the hob.
This lamp also stay on after the cooking
plate has been switched off to shown
that the hob surface is still hot.
This residual heat lasts for a rather long
time after the cooking plate has been
switched off.
During this period of time you
should avoid touching the hob
surface over the cooking area.
Please pay special attention to
ensuring children are not allowed
near the hob.
The lamp will switch off automatically as
soon as the surface temperature of the
cooking plate falls below 60°C.
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 will set the
control knob to the required position
for the cooking.
– You should use pots and pans with
flat bases (pans with the test mark for
glass-ceramic hobs are available
from specialist shops).
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 5 or 10 minutes before the end of
the cooking.
The residual heat of the hob will com-
plete the cooking.
– To save electricity, use pan lids
whenever possible.
– Never cook the food directly on the
glass ceramic cooktop, but in special
pans or containers.
–Do not scratch the cooktop with cut-
ting or sharp objects.
Do not use the glass ceramic surface
as a work surface.
Caution! the cooking hob becomes
very hot during operation.
Keep children well out of reach.
Fig. 3.7
DO NOT USE GLASSWARE ON CERAMIC HOBS.
DO NOT USE PANS WITH ROUGH CIRCULAR MACHINED BASE.
DEEP FA FRYING
For safety purposes when deep fat fry-
ing, do not fill the pan more than one
third full of oil.
DO OT cover the pan with a lid and
DO OT leave the pan unattended.
In the unfortunate event of a fire, leave
the pan where it is and turn off the con-
trol knobs.
Place a damp cloth or lid over the pan to
smother the flames. Leave the pan to
cool for at least 30minutes before mov-
ing the pan.
DO OT USE WATER ON THE FIRE.

12 Fig. 3.8
CLEANING
Before you begin cleaning make sure
that the appliance is switched off.
Remove any encrustation using the
scraper provided.
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 dam-
age 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 mix-
tures etc.
If any of these products has melted on
the ceramic surface, you should remove
it immediately (when the surface is still
hot) by using a scraper to avoid any per-
manent damage to the surface of the
hob (Available under part No. 103138).
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 irreparable way
ATTE TIO : MOST IMPORTA T!
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 ceram-
ic surface.
ADVICE FOR SAFE USE OF HE
COOK OP
• Before switching on make sure that you
have the correct knob for the hotplate
chosen. It is advisable to put the pan on
the hotplate before switching on and to
take it away after switching off.
• Use cookware with flat and even bot-
toms (be careful when using cast iron
vessels). Uneven bottoms can scratch
the glass ceramic surfaces. Be careful
that the bottom is clean and dry.
• Pots with aluminium bottoms may leave
silver streaks or spots on the bob.
• Do not leave wet or damp lids on the
bob.
• The glass-ceramic surface and pans
must be clean. Carefully eliminate any
food remains (especially containing
sugar), dirt etc. with the aid of a cleans-
ing agent.
• Make sure that the handles of cookware
do not stick out over the edge of the
cooker, to avoid them being knocked
over by accident. This also makes it
more difficult for children to reach the
cooking vessels.
• Do not lean over the cooking zones
when they are switched on.
• Do not drop heavy or sharp objects on
the glass ceramic cooktop. If the sur-
face is broken or damaged unplug the
cooktop and contact the after-sales
service.
• Do not put aluminium foil or plastic
objects on the cooking zones when they
are hot.
• Remember that the cooking zones
remain hot for some time after they are
switched off (about 30 mm.).
• Follow the cleaning instructions careful-
ly.
• If you note a crack in the cooktop,
switch the appliance off immediately
and call the After-Sales Service.
Do not scratch the cooktop with
cutting or sharp objects.
Do not use the glass ceramic sur-
face as a work surface.

COOKING ADVICE
S ERILIZA ION
Sterilization of foods to be conserved, in full and hermetically sealed jars, is done in the
following way:
a. Set the switch to position .
b. Set the thermostat knob to position 185 °C and preheat the oven.
c. Fill the dripping pan with hot water.
d. Set the jars onto the dripping pan making sure they do not touch each other and the
door and set the thermostat knob to position 135 °C.
When sterilization has begun, that is, when the contents of the jars start to bubble, turn
off the oven and let cool.

16
REGENERA ION
Set the switch to position and the thermostat knob to position 150° C.
Bread becomes fragrant again if wet with a few drops of water and put into the oven for
about 10 minutes at the highest temperature.
ROAS ING
To obtain classical roasting, it is necessary to remember:
– that it is advisable to maintain a temperature between 180 °C and 200 °C.
– that the cooking time depends on the quantity and the type of foods.
OVEN COOKING
Before introducing the food, preheat the oven to the desired temperature.
For a correct preheating operation, it is advisable to remove the tray from the oven and
introduce it together with the food, when the oven has reached the desired temperature.
Check the cooking time and turn off the oven 5 minutes before the theoretical time to
recuperate the stored heat.
SIMUL ANEOUS COOKING OF DIFFEREN FOODS
The fanned oven, allows you to cook different kinds of food at the same time.
Different foods such as fish, cake and meat can be cooked together without mixing the
smells and flavours together.
This is possible since the fats and vapours are oxidized while passing through the elec-
trical element and therefore are not deposited onto the foods.
The only precaution to follow are:
– The cooking temperatures of the different foods must be as close to as possible, with
a maximum difference of 20 °C - 25 °C.
– The introduction of the different dishes in the oven must be done at different times in
relation to the cooking times of each one.
This is a much more efficient method of cooking - saving both time and energy.
USE OF HE GRILL
Leave to warm up for approximately 5 minutes with the door closed.
Place the food inside positioning the rack as near as possible to the grill.
Insert the drip pan under the rack to collect the cooking juices.
Grill with the oven door closed.
Do not grill for longer than 30 minutes at any one time (Grilling for longer than the
recommended time may mean the appliance overheats).
Caution: the oven door becomes very hot during operation. Keep children well
out of reach.

17
GRILL PAN AND BAKING RAY
Grilling
In order to get the best results from your grill, please grill in the grill area - as shown in
the illustration 4.3 - this will given the most even results in the shortest time.
Baking
In order to achieve optimum results while baking, we recommend that you place your
baking tin / tray on top of the grill pan and grid inside the oven.
This will ensure that even baking results are achieved.
You can then place the grill pan in the shelf position you require as shown the recipe
you are using.
Please be aware that as with all cooking, results depend on personal taste - always
check your food regularly.
