Disposing of a household appliance separately avoids possible
negative consequences for the environment and health. It also
enables the constituent materials to be recovered, saving both energy
and resources. As a reminder of the need to dispose of household
appliances separately, the product is marked with a crossed-out
wheeled dustbin.
Please note:
•Induction hobs become hot and remain hot during and immediately
after use. Do not touch the hob until it has been allowed to cool.
•Keep children away from the appliance when in use.
•Never use the hob top for storage.
•Pan handles should never stand out beyond the edge of the
worktop. This will help to avoid children reaching them.
•Do not lean over the hob when it is in use.
•Follow the cleaning instructions carefully.
•Ensure the base of the saucepan is clean and dry before placing it
on the hob.
•Avoid hard shocks from cookware – the vitroceramic glass surface
is highly resistant but not unbreakable.

4
•Do not place hot lids flat on the hob top. A “suction” eect could
cause damage to the hob.
•Do not drag cookware across the hob top: in the long term, this
could cause damage to the hob.
•Do not store cleaning or flammable products in the unit below the
hob.
•Always use appropriate cookware.
•Do not cook unopened tins of food directly on the hob.
•Never put cooking foil or plastic materials on the ceramic surface
when the hob is hot. These materials could melt and cause
damage to the hob.
•This hob (Class 3) has been designed for use only as a cooking
appliance. Any other use should be considered incorrect and
therefore dangerous.
FOR THOSE WITH HEART PACEMAKERS OR ACTIVE IMPLANTS:
The function of this hob conforms to current electromagnetic
interference standards and thus is in total compliance with legal
requirements (2004/108/CE directives).
To avoid interference between your hob and a pacemaker, your
pacemaker must be designed and programmed in compliance with
the regulations that apply to it. As such, CDA guarantee only that our
product is compliant.
With regard to the compliance of the pacemaker or any potential
incompatibility, you should obtain information from the manufacturer
or your attending physician.

Important
•Do not use the hob if the glass surface is cracked or damaged to
prevent the risk of electric shock. Disconnect it from the power
supply.
•Ensure that the power cable of a connected electrical appliance
near the hob is not in contact with the cooking zones.

6
Cooking on Induction
The principle of induction cooking is based on magnetic eect.
When you put your cookware on an induction zone and switch it on,
the electronic boards in the hob produce induced currents in the base
of the cookware and instantly raise its temperature. This heat is then
transferred to the food inside the cookware.
The best cookware to use with induction cooking has thick flat bases,
as the heat will be better distributed meaning cooking is more even.
Most cookware is compatible with induction cooking.
There are three ways to check the suitability of your cookware:
1. Using a magnet to see if the base of the pan is magnetic: if the
magnet sticks, then the cookware is compatible.
2. Place the pan on one of the cooking zones and switch the
zone on. If the display continues to show the selected power
level then the cookware is compatible. If the display shows “ ”,
the cookware cannot be used on an induction hob.
3. Check the instructions or packaging of the pans for the
symbols indicating suitability for use with induction.

Using Your Hob
To switch the hob on
•To switch the power on, touch and hold the "On/o sensor" (1)
for approximately two seconds. The hob will beep, all four cooking
zone indicators will show “0” and the timer indicators will show "CL".
Please note: If a power level is not set within twenty seconds, the hob
will switch o automatically.
A decimal point will appear next to a cooking zone indicator's power
level when control/adjustment is available.
To activate a zone and set a power level
•Simply touch the desired zone's indicator (5) and then set the
desired power level using the heat setting slider sensor (2). The
standard power levels range from 1 (minimum) to 9 (maximum). The
hob will then begin heating providing that the correct cookware is
being used.
Please note: This hob also has a "Keep warm" function. The "Keep
warm" function is available between "0" and "1" heat settings and is
shown on a cooking zone indicator as " ". More info on the "Keep
warm" function is on page 15.
To deactivate a zone
•Touch the relevant zone's indicator (5) to activate zone control. You
can then use the heat setting slider sensor (2) to return the heat
setting to 0. The cooking zone indicator will display a "0" to confirm
that the zone is now inactive.

9
• If switching o multiple zones, the above steps need to be taken
for each zone. When all the zones are at "0", the hob will switch o
automatically after approximately twenty seconds.
•Alternatively, to switch o the hob immediately, touch and hold the
"On/o sensor" (1) for approximately two seconds.
Please note: Any zones that are still hot to the touch will display an
" " provided the mains power supply is not interrupted.
Booster
The hob is equipped with a booster function on all zones, allowing a
higher power level than the maximum for approximately ten minutes.
To activate the booster on a zone
•Touch the desired zone's indicator (5) and then touch the booster
function sensor (3). "P" will show in the cooking zone indicator to
show that the booster is on.
• The booster function automatically deactivates after 10 minutes of
usage. The cooking zone will continue to operate at its nominal
power at this point. The booster can be reactivated after this time
provided the hob's internal components have not overheated.
To deactivate the booster on a zone
• To cancel the booster at any time, touch the desired zone's
indicator (5) and then touch the booster function sensor or use the
heat setting slider sensor (2) to return the heat setting to 0.

10
Please note: The booster function cannot be used on two vertically
arranged, or bridged, cooking zones at the same time. This is to
prevent damage to the internal modules caused by overheating. In
the case of bridging, the booster function can not be used on either
zone.
If the appliance's electronic circuits or induction coils overheat
whilst the booster function is in operation then the function will be
automatically deactivated and the zone will continue to operate at its
nominal power. The booster function will be available again once the
internal components have been cooled suciently.
It is normal for a high pitched whirring noise to begin whilst the
booster function is in use. This is the cooling fan inside the hob
keeping the internal components as cool as possible.
If a pot is removed from the cooking zone whilst the booster function
is in use, the ten minute countdown continues.
Operating time limiter
In addition to the booster deactivation timer, each zone has an
operating time limiter to increase overall eciency and to prevent
the hob from being left on indefinitely. If a zone's heat setting is
not changed for a specific duration then the associated zone is
automatically switched o and residual heat indicator activated.
Zones can still be used as normal in accordance with the operating
instructions. The operating time limiter is set according to the last
selected heat setting. The maximum operating times for each setting
can be found on page 11

11
Operating time limiter durations
Timer/Minute Minder
The hob is equipped with a timer that allows a finish time to be set
for the end of cooking on any zone, between a minimum of 1 minute
and a maximum of 99 minutes. This timer can be used separately for
each zone, and an LED will indicate the zone positions for each of
the active timers. Once the timers are set, the timer display will show
the time remaining on the first zone to finish cooking. In normal use,
the timer ending prompts the zone heating to end as well. However
the timer can also be used as a minute minder to count down time
without halting heating.
Please note: At the end of the timer, the selected zone will switch o
and the timer indicators, and relevant timed zone LED, will flash. The
hob will beep for approximately two minutes. To switch o the beep
and the flashing display, touch any key. This beeping also occurs after
the minute minder time has elapsed and the same process to switch
o the beep applies.

The timer will then begin counting down.
• If multiple zones are in use then you will need to touch the timer
indicators (7) repeatedly to cycle through the zones until the timer
LED indicating the desired zone is flashing.
•The timed zone LEDs are oriented in a similar way to the zones;
•If no time is set within ten seconds, the timer will become inactive
and the zone will continue cooking.

13
To cancel the timer
•Touch the timed zone’s indicator (5) so that the decimal point
appears next to the set heat level (this indicates that control/
adjustment is available). Then, simply touch the timer indicators (7)
five times. Do this for each zone if necessary.
•Cancelling the timer will not switch o a zone. You should switch
the zone o manually if required.
To set the minute minder
• Switch the hob on using the on/o sensor (1) if necessary.
• With no heat level set, touch the timer indicators to activate the
minute minder. Use the heat setting slider sensor (2) to set the
individual minutes.
•Next, touch the timer indicators (7) again and use the heat setting
slider sensor (2) to set the tens of minutes.
• After approximately 3 seconds the selection will be confirmed and
the minute minder will begin counting down.
To cancel the minute minder
• Touch the timer indicators five times to deactivate the minute
minder. The display will switch o after the fifth touch.

14
Pause Function
The hob is equipped with a pause function that allows the user to
suspend the hob's operation for a brief period of time and to easily
continue cooking when convenient from the previously assigned
settings. This is particularly useful when your attention is drawn from
the hob, i.e. answering the door.
To activate the pause function
• At least one hob zone must be active. Press the pause function
sensor (11). All cooking zone indicators will show a pause symbol (II)
and the pause function sensor LED will illuminate.
To deactivate the pause function and resume cooking
• Press the pause function sensor (11) so that the Pause function LED
flashes and then touch any other sensor field on the control panel.
Please note: The pause function can only be used for a maximum of
10 minutes. If the hob is not reactivated within this time then the hob
switches itself o.
The pause sensor can be used to restore the last-set cooking
settings if the on/o sensor (1) is accidentally activated and the hob
switched o during use. Simply switch the hob back on using the on/
o sensor (1) and press the pause function sensor (10). This feature
is only available for approximately 7 seconds after the hob has been
switched o. Once power has been restored the pause function LED
will flash to indicate that the previous settings can still be restored.

15
Keep Warm Function
Each zone is equipped with a keep warm function that is designed to
keep food at a stable temperature. This allows the serving of food to
be delayed and also for the melting of butter or chocolate. The "Keep
warm" function is available between "0" and "1" heat settings and is
shown on a cooking zone indicator as " ".
To activate the keep warm function
• Switch the hob on if necessary and then simply touch the desired
zone's indicator (5) and set the power level using the heat setting
slider sensor (2) to " ". This level is between heat levels "0" and "1".
• Due to the potential for the spread of bacteria it is not advisable to
keep food warm for too long. The keep warm function’s duration is
limited to two hours in order to keep food as safe as possible.
To deactivate the keep warm function
• Touch the desired zone's indicator, unless adjustment is already
active (indicated by a decimal point next to the zone indicator's
power level), and then use the heat setting slider sensor (2) to set
the power to "0" or a higher heat setting if required.
Please note: The keep warm function also works on the left hand
zones when they are bridged. The same process for activating
the keep warm function applies for the bridged zones. Details on
activating the bridge function are on page 16.

16
Bridge Function
The hob is equipped with a bridge function which allows you to use
two heating zones with just one zone's controls. This function is
intended for use with pans such as fish kettles and is available for the
two zones on the left side.
To bridge the left-hand zones
Touch the cooking zone indicator (5) of the front-left zone and, at the
same time, touch the cooking zone indicator (5) of the rear-left zone.
If the bridge function has been enabled succesfully, the cooking zone
indicator (5) of the rear-left zone will display a ( ) symbol. The front
left zone controls will now alter both zones’ heat setting.
To cancel the bridge
Simply touch the same two indicators that were used to activate the
bridge function. If the bridge has been successfully cancelled then the
two zone indicators that were bridged will each display a 0. The zones
will now be individually operational.
Please note: Pans placed on bridged zones must always cover the
vertical markings (II) on the zones;

17
Safety Key Lock
To prevent accidental use, the hob has a safety key lock which
switches controls o temporarily or completely. The safety key lock
can be activated when the hob is turned on but not when power has
been switched o at, or the appliance disconnected from, the mains.
Disconnecting the appliance from the mains will deactivate the safety
key lock.
To switch on the lock, turn on the hob and then touch the front
right cooking zone indicator (5) and the booster function sensor (3)
simultaneously. Then touch the front right cooking zone indicator
once more. All cooking zone displays should show an ‘L’.
To switch o the lock, switch on the hob if necessary and then touch
the front right cooking zone indicator (5) and the booster function
sensor (3) simultaneously. Then touch the booster function sensor (3)
again. The hob will switch o but when reactivated will be unlocked.
Residual Heat Indicator
The hob is equipped with residual heat indicators to warn when any
of the zones are still hot to the touch after use. An “ ” will show in
a zone’s indicator if the relevant zone is above 45°c. You should
avoid touching any zone whilst the hob is in use or whilst residual
heat indicators are displayed. In the event of a power cut or failure,
the residual heat indicators will illuminate after the power supply is
restored. When there is no power supply to the hob however the
residual heat indicators will not work, yet the hob zone(s) may still be
hot, so extra care must be taken.

18
Ecient Use of Your Hob
The hob is equipped with zones designed to accommodate most
shapes and sizes of pan. For best results, only use pans with flat
bottoms. The most ecient use of the hob is shown below, where the
pan and zone are correctly chosen.
Use pan lids where possible to minimize the energy usage of your
appliance.
Pans placed on the left zones must always cover the vertical markings
(II) on a zone. When bridged, the pan(s) must cover both. Locating the
centre of a pan on the zone markings will ensure optimum eciency.

It is very important that the pans used on the hob are made of a suitable
material and have the correct type of base. The base of the pan and
the hob top must be clean before use to prevent any scratches on the
hob top.
Please note: Extra care should be taken if cast iron pans are used as
these have coarse bases which may damage the hob top.
Care and Maintenance
Always disconnect the appliance from the power supply before
undertaking any cleaning or maintenance.
Important:
•Steam cleaners must not be used when cleaning this appliance.
•You should use a non-abrasive cleaner to clean the hob top. Any
abrasive cleaner (including Cif) will scratch the surface and could
erase the control panel markings.
•Sugar and starch can cause permanent damage to the surface of
the hob. Wipe away any spillages immediately but be careful given
that the hob top will be hot during and after usage.
•Avoid letting pans boil over where possible to ensure that the need
for cleaning is minimal.
•Always use a soft sponge or cloth where possible. Utensils such as
scouring sponges and some brushes could cause scratches to the
hob top.
A cleaning guide is available on page 20.
