Description of cooking zones

Halogen elements

This type of element transmits heat through the radiation of the halogen lamp which it contains. It is held in high

regard because of its properties which are similar to the typical characteristics of gas: rapid response to com-

mands, instant display of power.

The radiant elements

This type of element is made up of many coils which guarantee the uniform distribution of heat on the bottom of the

pot, to ensure perfect cooking on low heat: stews, sauces or dishes that require reheating.

ing any other keys.

The cooking time countdown begins immediately.

The end of the programmed cooking time is indicated by

means of an acoustic signal (this lasts for 10 seconds)

and the cooking zone switches off.

Repeat the above-mentioned procedure for each plate

that you intend to programme.

19

Programmed time display

If one or more plates have been programmed, the dis-

play shows the time remaining for the plate which is

closest to the end of the programmed time, indicating

its position by means of the corresponding indicator light,

which will be on. The indicator lights that correspond to

the other programmed plates will flash.

To show the time remaining for the other programmed

plates, press repeatedly; the times of all the pro-

grammed plates will be shown in sequence, in an anti-

clockwise direction, beginning from the front left one

(only the corresponding indicator light will be on and the

display flashes)

Modification of programmed times

Proceed as per the paragraph “Programmed time dis-

play” until the time of the plate you intend to modify is

shown. Press the keys “+” and “-” to set the

new time. Confirm by pressing or wait 10 seconds

without pressing any keys.

Cancelling a programme

Display the time of the plate concerned (as in the para-

graph “Programmed time display”) and press the keys

“+” and “-” simultaneously; the programme

is reset and you exit the programming mode.

Safety devices

Acoustic signal

Some anomalies, such as:

• an object (pot, utensil, etc.) placed on the control

area for more than 10 seconds,

• a spillage on the control panel,

• sustained pressure on one of the keys, etc.

may cause the acoustic signal to go off.

Remove the cause of the malfunction to stop the acous-

tic signal. The hob remains locked; all you have to do is

unlock it to continues using it (the settings are saved). If

the cause of the malfunction is not eliminated, the acous-

tic signal will carry on, while the hob will switch off for

safety reasons.

Safety switch

The appliance comes with an automatic safety switch

which goes off after a certain time interval (see table) in

accordance with the selected power. During the safety

interruption, the letters “TI” and “ME” alternate on the

display.

for example: the right rear cooking zone is set on 5 and

the front left cooking zone is set on 2. The right rear

zone will switch off after 5 hours of operation, while the

left front zone will switch off after 6 hours of operation.

Inactivity

If the plate is switched on but is not used for approximately

2 minutes, the control lock function will be enabled. If

the same status remains for approximately another 4

minutes, the plate will switch off automatically.

Overheating

Prolonged use of the hob may cause the electrical com-

ponents to overheat.

A thermal protection device temporarily induces reduced

power (3) on the front cooking zones until the tempera-

ture has come down to an acceptable level.

21

Cleaning and maintenance

Practical tips for the use of the appliance

To get the best performance from your hob, it is essen-

tial follow certain fundamental rules during the cooking

process and when preparing food.

• Use flat-bottomed pans to ensure that they adhere to

the cooking zone perfectly.

• Always use pans with a diameter that is large enough

to cover the hotplate fully, so as to guarantee the use

of all the available heat.

• Make sure that the bottoms of the cookware is al-

ways dry and clean to guarantee correct adherence

and long life, not only for the cooking zones but also

for the cookware itself.

• Avoid using the same cookware that is used on gas

burners. The heat concentration on gas burners may

deform the bottom of the pot; therefore, this will not

allow you to obtain the desired result when used on a

glass ceramic hob.

• Never leave a cooking zone on without cookware on

it because as it heats up and rapidly reaches the

maximum level, it could damage the heating elements.

Always keep the hob clean. Before performing any main-

tenance on the hob, ensure that the heating zones are

off and that they have cooled down.

Stainless steel frame (only on some models)

Stainless steel may stain due to water that is very high

in calcium, if it is left in contact with the steel for pro-

longed periods of time or due to extremely aggressive

cleaning products (which contain phosphorus). We rec-

ommend that you rinse and dry thoroughly after clean-

ing the hob. If water is spilled on the hob, act rapidly and

dry it carefully.

Hob maintenance

The glass ceramic hob used as a heating surface is

perfectly smooth and not porous at all; furthermore, un-

der normal conditions of use, it resistant to heat shock

as well as mechanical shock. In order to ensure correct

preservation of all the hob’s properties, we recommend

that maintenance be carried out as follows:

• for ordinary maintenance, all you have to do is wash

it with a wet sponge, then dry it with kitchen towel

paper.

• If the hob is very dirty, scrub with a product that is

specifically suited to glass ceramic surfaces, rinse

and then dry.

• to remove thicker residuals, use a scraper. Act as

soon as possible, without waiting for the appliance to

cool down to prevent the residual from forming a crust.

You can obtain excellent results by using a stainless

steel wool sponge - which is specifically suited to

glass ceramic hobs- and which has been soaked in

water and soap.

• Once it has been cleaned, the hob may be treated

with a specific product for maintenance and protec-

tion: the invisible film left behind by this product pro-

tects the surface in case there are any leaks during

the cooking process. Remember to carry out these

operations when the appliance is lukewarm or cold.

• Also remember to always rinse with clean water and

to dry the hob thoroughly: product residuals could

form crusts the next time you cook.

Important tips

• Avoid using abrasive or corrosive detergents, such

as products in spray cans for barbecues and ovens,

stain-removers and anti-rust products, detergents in

powder form and sponges with abrasive surfaces, be-

cause these can all scratch the surface causing last-

ing damage.

• Remember to keep any object that could melt away

from the hob, for example plastic objects, sugar and

products with a high sugar content. If any of these

products are spilled on the hob, remove them imme-

diately (while the surface is still hot) with a razor-

blade scraper so as not to damage the surface.

• The hob must only be used for cooking. Do not

place any objects on the hob when it is not being

used. Do not use the hob as a resting surface (for

cutlery, cookware, scrubs, etc.) or as a cutting sur-

face.

• Aluminium packaging, aluminium film and plastic con-

tainers must never be left on the surfaces that are

still lukewarm or hot.

• Do not use steam or high-pressure cleaners to clean

the appliance.
