maintenance or repair work.
Correct use
- In the event of overheating, greases and oils can ignite easily.
Always stay in the vicinity of the appliance when using greases and
oils.
Never put out fires caused by oil or grease with water. Switch off the
appliance and carefully smother the flames with a lid or fire blanket.
- Flames could ignite the grease filters of the extractor hood. Do not
prepare flambé dishes under the extractor hood.
- Do not use the hob to prepare preserves or to heat cans. Cooking to
prepare preserves or heating closed tins can result in bursting due to
overpressure.
SAFETY INSTRUCTIONS AND WARNINGS

5
- If spraying aerosols, slightly flammable liquids or combustible
materials, these can ignite. For this reason do not store slightly
flammable objects in the drawers directly under the hob. The plate
drawer, if present, must be made of heat-resistant material.
- Do not heat empty pots or pans.
- When covering the hob, there is a danger that the cover material will
ignite, shatter or melt if the ignition is switched on inadvertently or
the residual heat is removed. Do not cover the hob, for example with
cover plates, a cloth or protective film.
- If an electrical appliance is used in the immediate vicinity of the hob,
e.g. a blender, make sure that the power supply cable does not
come into contact with the hob. The insulation of the power cord may
be damaged.
- If the hob has been recessed behind the door of a piece of furniture,
put it into operation only with the unit door open.Close the unit door
only when the residual heat indicator lights are off.
- The appliance in operation is very hot and also remains hot for some
time after it has been switched off. The risk of burns no longer exists
only when the residual heat indicators are off.
- If the hob is very hot, it is possible to burn yourself. We recommend
protecting your hands from the heat by using suitable handles or pot
holders. Use only dry gloves or pot holders. Wet or damp fabrics
conduct heat better and can cause scalding.
- If the hob is switched on or has been inadvertently switched on, or
in the event of residual heat, there is a risk that metal objects may
overheat (danger of burns).
Other types of materials could melt or ignite.
Damp lids could stick to the hob due to the suction effect.
Do not use the appliance as a support surface.
Switch off the cooking zones after use.
- Pots from which liquids evaporate directly can damage the glass
ceramic surface. Always stay in the vicinity of the appliance when it
is operating.
- Pots and pans with a rough base could scratch the glass ceramic
hob. Use only pots and pans with a smooth base.
SAFETY INSTRUCTIONS AND WARNINGS

6
- If sugar or food containing sugar, plastic or tinfoil ends up on the
hob and melts, they could damage when cooling the glass ceramic
surface. Immediately turn off the hob and remove these substances
with a suitable spatula. Wear oven gloves. Clean the cooking zones
with a glass ceramic cleaner as soon as they have cooled.
- To move the dishes it is always advisable to lift them. In this way the
surface of the surface is not scratched.
- Salt, sugar or grains of sand, e.g. derived from clean vegetables,
can scratch it if they filter beneath the bottom of the kitchenware.
Make sure that the glass ceramic surface and the bottom of the
kitchenware are clean before placing them on the hob.
- Even light objects (e.g. a salt-cellar) falling over them can crack or
damage the glass ceramic plate.
Attention: DO NOT drop any objects on the glass ceramic surface.
- Hot objects may damage the electronics that are found
under the sensor keys and lights. Never place very hot pots or pans
on the sensor buttons and lights.
- As induction hobs heat up very quickly, the temperature of the
bottom of the pots can very quickly reach the point of self-
combustion of fats and oils. Always stay in the vicinity of the
appliance when it is operating.
- Heat up greases and oils for a maximum of one minute
- Warning for persons with pacemakers: bear in mind that an
electromagnetic field is generated in the immediate vicinity of
the device when it is operating. The possibility of pacemaker
functioning being affected is very remote. If in doubt, contact the
pacemaker manufacturer or your doctor.
- The electromagnetic field of the hob when on can influence the
operation of magnetisable objects.
Credit cards, life-saving devices, pocket calculators etc. must not be
found in the immediate vicinity of a hob when on.
- Never use two pans on a single cooking zone.
SAFETY INSTRUCTIONS AND WARNINGS

7
- Metal objects stored in a drawer under the appliance may become
incandescent if the appliance is used for a prolonged period. Do not
store metal objects in a drawer located directly below the hob.
- The appliance is equipped with a cooling fan. If there is a drawer
beneath the recessed appliance, a sufficient distance must be
observed between the contents of the drawer and the bottom of the
appliance, in order to ensure the necessary ventilation of the hob.
Do not store small or pointed objects or paper in the drawer as these
may enter the casing through the ventilation slots or they may be
sucked in and thus damage the fan or impair cooling.
General warnings
•The installation and connection of the appliance can only be carried out by a
qualified electrician. Contact an electrician who is knowledgeable of the local rules
and additional regulations issued by the local electricity operator and ensure that the
work is carried out in compliance with the same. The manufacturer is not responsible
for damage caused by incorrect installation or connection of the appliance. To prevent
damage to the appliance, recess it only after installing the units and the extractor hood.
•The electrical safety of the appliance is only guaranteed if it is connected to a compliant
earthing conductor. It is very important to verify that this condition is fulfilled as it is a
fundamental premise. If in doubt, have the system checked by a specialist technician.
The manufacturer is not responsible for damage caused by the absence or interruption
of the earthing conductor.
•The appliance must not be connected to the mains with an extension cord; extensions
do not guarantee the necessary safety of the appliance.
•The hob cannot be recessed above a dishwasher, a tumble drier, a washing machine,
a refrigerator, a freezer, an oven or a cooker without a fan for cooling of the appliance.
•On the one hand, partly high emission temperatures can damage these appliances, on
the other ventilation of the hob is not guaranteed.
•Increase this hob only on ovens or electric cookers equipped with a smoke cooling
system.
•If there is a drawer under the appliance, do not store flammable objects in it (e.g. spray
cans).
•Make sure that the connection cable to the hob electrical system is not subjected to
mechanical stress after installation (e.g. due to a drawer).
SAFETY INSTRUCTIONS AND WARNINGS

•The worktop veneers must be prepared with a heat-resistant adhesive (100°C) so that
they cannot detach or become deformed. The end wall profiles must be heat-resistant.
•On one side and on the back side of a recessed glass ceramic hob there can be walls
or furniture of any height, while on the other side any piece of furniture or appliance
present must not be higher than the hob.

•Turn the hob upside down and apply the seal supplied with the accessories kit to the
outside edge evenly.
If the appliance is installed above a cooker hood, the safety distance indicated by
the hood manufacturer must be observed. In the absence of precise indications or if
flammable materials (e.g. a shelf) are located above the appliance, the safety distance
must be at least 760mm.
If several appliances are installed under the extractor hood, for which different safety
distances are envisaged, observe the greater safety distance indicated.
•Make the notch in the worktop according to the dimensions relative to the model (see
figure above).
•Respect the minimum distance of 50 mm towards the rear wall and a minimum
distance of 100 mm to the right or left towards a possible side wall.

9
ATTENTION: In order to ensure correct operation of the appliance,
a gap of at least 5 mm must be left for the length of recessing on
the front of the unit during installation.
This is because the electronic controls are equipped with a
protection device which, when the temperature of the electronic
part exceeds 85°C, turns off the hob until it returns below
this limit. During operation then a fan comes on to guarantee the
necessary air flow to avoid exceeding of the temperature limit.
Therefore provide the installation with an underlying protection
that in any case guarantees a flow of air from the back of the unit
or, if the hob is installed above an oven, a type of insulation that is
adequate to ensure that this temperature is not exceeded. In the
case of overtemperature, the electronic part may fail, for which the
manufacturer declines all responsibility.
Safety distance to the sides/rear wall
When recessing a hob, on the back and on the side (on the right or on the left) there
should preferably be unit or room walls (see images above):
- 50 mm minimum safety distance on the back from the work top notch up to the rear
edge of the worktop.
- 100 mm minimum safety distance on the right and/or on the left side of the worktop
notch to the adjacent unit (e.g. column unit) or to the wall
Intermediate shelf
The installation of an intermediate shelf under a cooking hob is not necessary but is
permissible. To lay an electrical power cord, prepare a 10mm slot on the back. To allow
better ventilation of the hob, it is advisable to leave a 20mm slot.

Downward safety distance
To guarantee correct ventilation, it is necessary to maintain a minimum distance between the
appliance and an oven, an intermediate shelf or a drawer.
The minimum distance between the lower edge of the hob and
- the upper edge of an oven must be 15mm
- the upper edge of an intermediate shelf must be 15mm
- the bottom of a drawer must be 75mm
Safety distance from the niche covering
If a covering is applied to the niche, a minimum distance must be observed between the
worktop niche and the covering as high temperatures can damage or modify the materials.
If the covering is made of flammable material (e.g. wood), the minimum distance between the
worktop and covering must be 50mm.
If the covering is made of non-flammable material (e.g. metal, natural stone, ceramic tiles),
the minimum distance between the worktop notch and and the covering must be 50mm less
the thickness of the covering.
Example: covering thickness 15mm
50mm - 15mm = minimum distance 35mm.
Electrical connection
Before making the electrical connection, make sure that the electrical network has
the characteristics indicated on the data plate. Also check that there is an efficient
earthing system according to the law in force.
If the appliance is not supplied with a cable and/or the related plug, apply a
standardised plug with a correct size for the load to be supported.
A direct connection to the line is also possible. In this case it is necessary to
interpose an omnipolar switch with a minimum contact opening of 3 mm, suitable
for the load to be supported and in compliance with the regulations in force (the
earthing conductor not to be interrupted by the circuit breaker).

CONTROL DESCRIPTION

Practical tips for use of the appliances.
•Use only pots with a thick base and a flat
bottom that are not much larger than the
size of the cooking zone;
•The pots must not have irregularities on
the part in contact with the glass to avoid
scratching it;
•Do not turn on the heating element if there
is not a pot present;
•Do not cook directly on the glass ceramic
cooking zone;
•Prevent liquids from spilling out of the pots;
•Turn off the cooking zones just before the
end of the cooking area.
In addition, to obtain the best performance
from the hob:
•Use pots with a flat, thick base to ensure
that they adhere perfectly to the heating
zone.
•Use pots of sufficient diameter to completely
cover the heating zone in order to guarantee
exploitation of all the heat available.
•Ensure the base of the cookware is always
perfectly dry and clean to guarantee correct
adherence and durability, both to the
cooking zones and to the pots themselves.
•Avoid using the same pans used on gas
burners: the concentration of heat on gas
burners can deform the base of the pot,
which loses adhesion.
