Induction introduction
Induction hobs only heat the pan rather than the cooking surface heating up like a
standard electric hob. They do this by creating a magnetic field between the pan
base and an element underneath the glass top; this makes induction hobs safer
and cheaper to run as they use only the precise amount of energy you need.
Because induction hobs create a magnetic field, pans need to either be made from
a magnet metal such as cast iron or steel, or have a magnetic base. You can check
whether your existing cookware is suitable by carrying out a magnet test: move a
magnet towards the base of the pan. If it is attracted, the pan is suitable for
induction. If you do not have a magnet then you can put some water in the pan
you want to check, if the symbol does not flash in the cooking zone
indicator and the water is heating, the pan is suitable.
If your current cookware isn’t suitable, then when purchasing new cookware you
must ensure the packaging says they are compatible with induction hobs or that
they pass the magnetic test detailed above. Please note cookware made from the
following materials is not suitable: pure stainless steel, aluminum or copper
without a magnetic base, glass, wood, porcelain, ceramic, and earthenware.
Note:
•Because of the powerful electromagnetic field, induction may not be suitable
if you have a pacemaker fitted
•The glass of an induction hob only becomes hot because the pan eventually
warms it up

Pans & Energy Saving
•Only use cookware with a base suitable for induction cooking. Look for the
induction symbol on the packaging or on the bottom of the pan.
•You can check whether your cookware is suitable by carrying out a magnet test.
Move a magnet towards the base of the pan. If it is attracted, the pan is
suitable for induction.
•If you do not have a magnet:
•Put some water in the pan you want to check.
•Follow the steps under ‘To start cooking’.
•If does not flash in the display and the water is heating, the pan is
suitable.
•Cookware made from the following materials is not suitable: pure
stainless steel, aluminium or copper without a magnetic base, glass,
wood, porcelain, ceramic, and earthenware
The following advice is to prevent damage to pans and help you save energy:

Usage
Using the touch controls
The controls respond to touch, so you don’t need to apply pressure to them.
Below are tips on how to use the controls:
•Use the ball of your finger, not its tip.
•You will hear a beep each time a touch is registered.
•Make sure the controls are always clean, dry, and that there is no object (e.g. a
utensil or a cloth) covering them. Even a thin film of water may make the
controls difficult to operate.
Indicators
Cooking zone indicators
The cooking zone indicators are next to the cooking zone
controls. The indicator will show the power level of the
zone, if a zone has any residual heat after operation and
if it is being used with the timer.
Timer indicator
The timer indicator is located to the left of the
power level controls. It will show the time that has been
set for the minute minder and if one cooking zone is to be
turned off after a period of time (maximum of 99 minutes).

Usage
To use a cooking zone
Note:
•When you touch a symbol, the respective function is activated.
•Always keep the controls dry. Moisture reduces their effectiveness.
•Do not pull pans close to the displays and sensors. The electronics could
overheat.
Warnings:
•When it is first used, it is normal for the cooking zone to give off odours; this
does not pose any risk and does not indicate a malfunction; they will
disappear in time.
•The kitchen will become hot and humid when this appliance is used. You
must therefore ensure that the kitchen is well ventilated: either keep the
natural ventilation apertures open, or install a ventilation system (extractor
hood).
•If using the appliance intensively for prolonged periods, you may require
additional ventilation (e.g. by opening a window) or more effective
ventilation (e.g. by increasing the hob's ventilation, if possible).
1. Turn on the appliance at the circuit, the appliance will beep and all indication
lights will flash and then go out.
2. Touch the power on/off control , all indicators will display a ‘-’symbol.
3. Place a suitable pan on the cooking zone that you wish to use.
1. Make sure the bottom of the pan and the surface of the cooking zone
are clean and dry.
17

Usage
4. Select the cooking zone you want by touching the required cooking zone
control and the indicator of the zone you have selected will flash.
5. Use the power level controls to select the required power, this will be shown
on the cooking zone indicator of the cooking zone that is being used.
6. Please note that if a power level is not selected within 5 seconds of touching
the required cooking zone control it will be deselected. You will need to
retouch the required cooking zone again and select the power level you
require. If a cooking zone and power level is not selected within 1 minute of
powering on the hob, the hob will automatically switch off. If this happens
then you will need to start again from step 2.
Note: If a cooking zone indicator flashes with the symbol, this means:
i. You have not placed a pan on the correct cooking zone
ii. The pan you’re using is not suitable for induction cooking
iii. The pan is too small or not properly centred on the cooking zone.
No heating takes place unless there is a suitable pan on the cooking zone. The
display will automatically turn off after 1 minute if no suitable pan is placed on
it.
