Causes of damage:
The base of the pans
The rough bases of pans may scratch the hob.
Avoid leaving empty pans on the hotplates. These may
cause damage.
Hot pans
Never rest hot pans on the control panel, the indicator area or the hob surround.
Salt, sugar and sand
salt, sugar and sand may scratch the ceran glass.
Do not lean on the hob or use it as work surface.
Hard and pointed objects
Hard or pointed objects may cause damage if they fall onto the hob.
Spilt food
Sugar and other similar products may damage the hob.
These products should be removed immediately using a
glass scraper.
Inappropriate cleaning products
Discolorations in the metal are caused by using unsuitable cleaning products and
wear as a result of contact with pans.
Plastic and foil
Aluminum foil and plastic containers will melt if placed on the hot areas of the hob
Advice on saving energy
Use a pan with thick flat base. Curved bases increase
energy consumption.
Place a ruler on the base of the pan, if there are no
gaps, the base of the pan is completely flat.
The diameter of the base of the pan should fit the
size of the hotplate.
Check if the manufacturer has indicated the upper diameter of the pan. In general,
this is greater than the diameter of the base of the pan.
If the diameter of the pan does not fit the diameter of the hotplate, you are
recommended to use a pan which is larger than the size of the hotplate, or else about
half the energy will be lost.

Electric Induction hobs Chef’s

Choose pans which are the right size for the amount of food to be prepared. A large
pan which is half full will consume a lot of energy.
Always centre the pan on the hotplate and always cover the pan with the matching
lid. Cooking without using the lid quadruples energy consumption.
Cook using small amounts of water. This will save energy and will also help green
vegetables retain their vitamins and minerals.
During their cooking, food such as stews, soups may heat up too quickly without
any indication, spilling out of the cookware.
It is therefore advisable to heat this type of food gently, selecting a suitable power
level and stirring the contents before and during cooking.
We recommend not to use for Induction hob pots that have been used in a gas hob
fire can deform the flatness of bottom). In case of use, check that bottom is flat.

Important notes
Safety in use is only guaranteed if the technical installation of the hob has been
carried out correctly and in accordance with the installation instructions. The installation
technician shall be liable for any damage cause as a result of incorrect installation.
Only an authorized technician is able to connect the appliance. The guidelines set
out by the electricity provider must be observed.
This appliance should be used only with an earthed connection.
Using this appliance without an earthed connection or after it has been incorrectly
installated may, in very rare cases, cause serious harm.
The manufacturer accepts no responsibility for any malfunction or damage which is
caused by incorrect electrical installation.
If the appliance is not fitted with an accessible plug, disconnecting means must be
incorporated in the fixed installation, in accordance with the installation regulations.
The power cable must be positioned so that it does not touch any of the hot parts of
the hob.
Refrigerators, dishwashers, ovens, or washing machines must not be installed
under the induction hob.

Any change to the appliance’s interior, including changing the power cable, must be
performed by the Customer Service.
Preparing the Kitchen
The worktop should be flat and horizontal. The aperture should be cut before the
appliance is installed. Remove any shavings, as these can affect the operation of the
electrical components. When the cutting has been completed, the unit’s stability should
be checked again.
Surfaces which have been cut should be sealed so that they are heat resistant and
so that they do not swell when moist.
The kitchen units to be fitted must resist temperatures of up to 90oC.
The gap between the aperture and the side wall must be at least: 40 mm
It is not recommended that the hob be placed between two side walls but, if this is
the case, a gap of at least 200 mm should also be left on one side.
If the induction hob is installed above a sterilizer there must be a gap of 70 mm from
the top of worktop to the top of the sterilizer.
If the induction hob is installed without sterilizer or above a drawer, the worktop
thick around the hob must be 20 mm as minimum.
If the interior width of the kitchen unit is less than 700 mm, a 80 mm – long cut must
be made in the side walls from the top section of the hob.
Taking into account the hob ventilation:
An aperture must be cut in the top section of the back of the kitchen unit, 680 mm
wide and 45 mm high.
There must be a gap of 20 mm between the back of the kitchen unit and the kitchen
wall.
if the hob is installed above a drawer, allow a gap of 65 mm between the drawer
and the top section of the worktop.
Installing and connecting the hob
The earth wire ( green and yellow) should be connected first and disconnected last.
It should also be longer than the others, so that even if the hob is moving the other
wires can be disconnected before the earth wire.

3. Green and Yellow
Is required 16A electrical installation at
customer’s house (electrical circuit, socket and fuse ).
Do not trap the lead during installation and do not guide it over sharp edges.
The hob and the worktop should not be sealed with silicone as the hob itself has a
seal which serves this function.
Removing the hob
Disconnect the cooker from the power supply.
Push out the hob from below
3. Induction cooking
Advantages of induction cooking
ØGreater speed in cooking and frying; as the pan is heated directly.
ØReduced energy consumption
ØCleaner and easier to use; spilt food does not burn as much on the hob.
ØCooking control and safety; the hob supplies or cuts off the heat as soon
as the controls are operated. The Induction hotplate stops supplying heat if
the pan is removed before the power has been switched off.
Suitable pans
Ferromagnetic pans are the only pans which are suitable for induction cooking.
They can be made of:
·enameled steel
·cast iron
·specially designed cookware for induction cooking made from stainless steel
Special pans for induction cooking.
Other types of special pans are available for induction cooking, where the base of
the pan is not entirely ferromagnetic. Check the diameter as this could affect the pan
detection as well as the cooking results.

Checking pans using a magnet
To find out whether the pans are suitable, check
that they are attracted to a magnet.
The manufacturer will usually indicate if their pans
are suitable for induction cooking.
Unsuitable pans. Never use pans made from:
·standard, high quality steel
·glass / earthenware
·copper / aluminum
Characteristics of the base of the pan
The characteristics of the base of the pan can
affect the evenness of the cooking.
Pans which are made from heat-diffusing materials
( such as “sandwich” pans made from stainless
steel) distribute the heat evenly, saving time and
energy.
No pan or incorrect size pan
If no pan is place on the hotplate, or the pan is not made of a suitable material or it
is not a suitable size, the heat setting on the hotplate indicator will flash.
Place a suitable pan on the hotplate to stop the indicator flashing. If there is a delay
of more than 90 seconds, the hotplate switches off automatically.
Empty pans or pans with a thin base
Do not heat empty pans and do not use pans with thin bases. Although your hob is
equipped with an internal safety system, empty cookware can heat up so quickly that
the “automatic OFF” function does not have time to react and a very high temperature
may be reached. The base of the pan could melt and damage the hob’s glass surface.
If this happens, do not touch the pan and switch off the hotplate. If it does not work
after cooling, contact our Local Service Center or dealer.
Pan detection
Each hotplate has a minimum limit for pan detection which varies according to the
material from which the pan being used is made. It is for this reason you are
recommended to use a hotplate which matches the diameter of the pan.
