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.

6
•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.
•NEVER run an empty pan on an induction hob (nor any hob).
•Do not switch on the hob until a pan has been placed on it.
•Keep the control panel(s) clean and free from grease, grime or
debris as these can hamper activity or cause unwanted activation.
•Do not lean over pans when they are warming up or cooking.
•Do not pour any liquids down the extractor area. If any spillages
do occur, follow the care and maintenance section on page 24.
Saving energy
Using energy in a responsible way not only saves money but also
helps the environment. The following will help you to save energy:
•Use proper pans for cooking. A saucepan should never be smaller
than a zone. Always remember to cover any pans.
•Ensure pans and the hob are kept clean. Soils can prevent heat
transfer and repeatedly burnt-on spillages can often only be
removed by products which cause damage to the environment.
•Do not uncover the pan too often (a watched pot never boils!).
Be sure to recycle all of the packaging. All packaging materials
used are 100% recyclable.

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, base or packaging of the pans for the
symbols indicating suitability for use with induction:

Using your hob(s)
To switch a hob on
•To switch the power on, touch and hold the on/o sensor (9) for
approximately one second. The hob will beep and all cooking zone
indicators will show ‘0’. The inductor modules will click faintly when
turning the hob on (and o).
Please note: If a power level is not set within ten seconds, the hob
will switch o automatically.
To activate a zone and set a power level
•Simply set the desired power level using the heat setting slider
sensor (11). 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.
To deactivate a zone
•Simply use the heat setting slider sensor (11) to return the heat
setting to '0' for that zone.
• If switching o multiple zones, the above step needs to be taken
for each zone. When all the zones are at '0', the hob will switch o
automatically after approximately ten seconds.
•Alternatively, to switch o the hob immediately, touch and hold the
on/o sensor (9) for approximately two seconds.
Please note: Any zones that are still hot to the touch will display the
symbol ' ' provided the mains power supply is not interrupted.

11
Booster function
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
•Regardless of whether a power level is already set, simply touch
the '+' symbol at the end of the slider for the relevant zone. 'P'
will be displayed on 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, use the heat setting slider sensor
(11) to return the heat setting to '0' or an alternative level.
Please note: The booster function can not be used on all zones at
once. If two zones in a vertically aligned module are placed on boost,
then the first zone to have been placed on boost will be reduced
to power level 5. Additionally, a bridged pair of zones can not be
boosted. This is to help protect the hob's internal components.
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.

12
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 should continue.
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 below.

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 119 minutes. This timer can be used separately for
each zone, and the timer activity indicator (3) will illuminate faintly
on each zone for which it is set and remain brightest on the first
zone to end. 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 will flash. The hob will beep for approximately
two minutes. To switch o the beep, touch the timer minus and plus
setting sensors (5 & 7) simultaneously. This beeping also occurs after
the minute minder time has elapsed and the same process to switch
o the beep applies.
If no time is set within 5 seconds of activating the timer, then it will
deactivate automatically.
To set the timer
•First switch on the hob if necessary and set the desired zone to the
power level required.
•Touch the timer minus setting sensor (5) and the timer plus setting
sensor (7) simultaneously. The timer display (6) will illuminate.
•A clock symbol (the timer activity indicator) will appear next to the
power level of the leftmost active zone. This clock indicates which

14
zone the subsequent timer adjustment will aect.
•Next, use the timer plus setting sensor (7) and the timer minus
setting sensor (5) to set the desired timer duration. The timer is
increased in 1 minute increments per each press of the + or -
sensors. If you hold your finger down on either sensor, after
a few seconds, the time will increase by 5 minute increments.
Continuing to hold your finger down will increase the time by 10
minute increments.
To set the timer on multiple zones
• To time each zone when multiple zones are running, set the time for
one zone, as per the section ‘To set the timer’. Wait for
approximately 4 seconds for the time to engage and begin
counting down before switching zones. The timer display (6) will
revert to the soonest time to end.
• Touch the timer minus and plus setting sensors (5 & 7) repeatedly
to cycle through the zones until the timer activity indicator for the
desired zone is lit. Each press will cycle the zone timer one zone to
the right. The zone for which timer adjustment is active will display
a bright clock symbol. Any zones which already have a timer set will
display a dimly lit clock symbol.
• Next, use the timer plus setting sensor (7) and the timer minus
setting sensor (5) to set the desired timer duration. Wait for
approximately 4 seconds for the time to engage and begin
counting down before switching zones. The timer display (6) will
revert to the soonest time to end.
To cancel the timer
• If multiple zones are in use then you will need to touch the timer

15
minus and plus setting sensors (5 & 7) repeatedly to cycle through
the zones until the timer activity indicator for the desired zone is
illuminated brightly.
•Reduce the time on the timer display (6) to 0.00 using the timer
minus setting selector (5). Wait for approximately 4 seconds for the
timer to confirm cancellation before moving on to another zone.
To set the minute minder
• Switch the hob on using the on/o sensor (9) if necessary.
• With no heat level set, touch the timer minus setting sensor (5) and
the timer plus setting sensor (7) simultaneously. The timer display
(6), and the clock symbol beneath it, will illuminate. If a heat level
is set, press the minus and plus setting sensors simultaneously
as many times as necessary until the clock symbol between the
timer sensors is lit.
•Next, use the timer plus setting sensor (7) and the timer minus
setting sensor (5) to set the desired minute minder duration. The
entry will confirm after approximately 4 seconds and begin counting
down.
• Once the set time has elapsed, an acoustic signal will begin to
sound for approximately two minutes. To cancel this signal, press
the timer minus setting sensor (5) and timer plus setting sensor (7)
simultaneously.
To cancel the minute minder
•Press the timer minus and plus setting sensors (5 & 7)
simultaneously to activate timer adjustment (signified by solidly lit
decimal point) and then reduce the time on the timer display (6) to
0.00 using the timer minus setting selector (5).

16
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’ (8). 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 (8) so that the Pause function
LED goes out. A heat setting slider will then illuminate indicating
a swiping motion. Run the ball of your finger from left to right
to deactivate the pause, as the light indicates. The hob should then
resume cooking as it was before the pause function was activated.
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 (9) is accidentally activated and the hob
switched o during use. Simply switch the hob back on using the on/
o sensor (9) and press the pause function sensor (8). This feature
is only available for approximately 7 seconds after the hob has been
switched o.

17
Once power has been restored the pause function LED will flash to
indicate that the previous settings can still be restored.
Keep warm function
Each zone is equipped with a keep warm function that is designed to
keep food at a stable temperature. This allows for the serving of food
to be delayed and also for the melting of butter or chocolate.
• A flat-bottomed pan must be used so that the temperature can be
accurately measured by the detector within the heating zone.
• Due to the potential for the spread of bacteria it is not advisable to
keep food warm for more than two hours.
• There are three temperature levels that can be set: 42°C, 70°C and
94°C.
To activate the keep warm function
• Touch the desired zone’s keep warm function sensor (12) either
once, twice or three times.
• Touching the keep warm function sensor (12) once will activate the
42°C heating level.
• Touching the keep warm function sensor (12) twice will activate the
70°C heating level.
• Touching the keep warm function sensor (12) three times will
activate the 94°C heating level.
Please note: The keep warm setting indicators will display the ( )
symbol when the 42°C heating level is active, the ( ) symbol will be
displayed when the 70°C heating level is active and the ( ) symbol

18
will be displayed when the 94°C heating level is active. The cooking
zone indicator will display a .
To deactivate the keep warm function
• Touch the relevant zone’s keep warm function sensor (12) the
required number of times until the display reads ‘0’ again.
Please note: Any zones that are still hot to the touch will display an
' ' provided the mains power supply is not interrupted.
Bridge function
The hobs are 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 all
zones. However, only vertically aligned zones can be bridged.
To bridge zones
Touch both heat setting slider sensors (11) of the zones that you want
to bridge. A successful zone bridge will be signified by the bridge
function indicator (4) of both zones illuminating. Only one cooking
zone indicator (2) will be lit however, and it is this zone’s controls that
should be used to control the bridge.
To cancel the bridge
Simply touch the same two sliders 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.

19
Please note: Pans placed on bridged zones must always cover the
vertical markings (II) on the zones;
Control lock
To prevent accidental use or inadvertent setting
changes, the hob has a control lock which disables
controls. Disconnecting the appliance from the mains will
deactivate the control lock.
To activate the control lock
Turn on the hob, set a power level if required, and then touch and
hold the lock sensor (10) for approximately 1 second. The hob should
beep and the LED above the sensor should illuminate. The hob will
now be significantly more protected from inadvertent use. The on/o
sensor (9) can still be used to switch the hob o but when it is turned
back on the lock will still be active.
To deactivate the control lock
To switch o the lock, switch on the hob if necessary and then touch
and hold the lock sensor (10) for approximately 1 second. The hob
should beep and the LED above the sensor should extinguish. The
hob should now be usable as normal.
Safety key lock
To further protect the hob from accidental use or to help prevent
children from activating the hob, it also features a more intricate safety
key lock.

20
To activate the safety key lock
Turn on the hob but do not set a power level on any zone. Touch the
lock sensor and the pause sensor simultaneously, release them and
touch the lock sensor again. This must be done within 10 seconds
of switching the hob on. An ‘L’ symbol will appear on all displays to
confirm that the safety key lock is active. You can switch the appliance
o when the lock is active, but it will remain active when you switch
the appliance back on.
To deactivate the safety key lock
•To switch o the safety key lock completely, switch on the hob
if necessary and touch the lock sensor and the pause sensor
simultaneously, release them and touch the pause sensor again.
•To switch o the safety key lock temporarily, switch on the hob
if necessary and touch the lock sensor and the pause sensor
simultaneously. This will mean that the safety key lock will be active
again the next time you switch on the hob and is useful if you want
the controls to be locked all of the time.
Residual heat indicators
The hob is equipped with residual heat indicators to warn when zones
are still hot to the touch after use. The symbol ‘ ’ will show in a zone’s
indicator for a preset period of time after the hob has been used.
IMPORTANT: 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 not illuminate after
the power supply is restored, nor when there is no power supply to
