IMPORTANT INFORMATION FOR CORRECT DISPOSAL OF THE
PRODUCT IN ACCORDANCE WITH EC DIRECTIVE 2012/19/EU.
At the end of its working life, the product must be taken to a special
local authority waste collection centre or to a dealer providing
appliance recycling services.
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, dropping pepper mills etc. – the
vitroceramic glass surface is highly resistant but not unbreakable.

5
•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 in a domestic environment. 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.
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 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" (5) for
approximately two seconds. The hob will beep and all four cooking
zone indicators will show “0”.
Please note: If a zone is not selected nor a power level set within ten
seconds, the hob will switch o automatically.
To set the power level
•Touch the cooking zone selector (9) for the required zone. The
hob will beep and the zone display will show a pulsating "0" on the
selected zone's indicator.
•Select the desired heat setting using the "+" or "-" selectors. The
power level ranges from 1 (minimum) to 9 (maximum). The hob
will begin heating and the cooking zone indicator will pulsate for
approximately ten seconds before remaining solidly lit. Inactive
cooking zones' indicators will dim at this point.
• This hob also has a "Keep warm" function as well as a "Booster"
function. The "Keep warm" function is available between "0" and "1"
heat settings and is shown on a cooking zone indicator as " ". The
Booster function is available after heat setting "9" and is shown on a
cooking zone indicator as "P".
Please note: After zone selection, the zone will remain active for
approximately ten seconds. If no key is touched during this time, the
zone will become inactive and the hob will switch o automatically.

10
To turn the power o to a zone
•To switch o a zone, touch the cooking zone selector (9) so that
the cooking zone indicator (7) pulsates. Then press and hold the
cooking zone selector (9) for approximately three seconds. The
cooking zone indicator will display a "0" to confirm that the zone is
now inactive but will display an " " or " " if the zone is still hot to the
touch.
• 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" (5) for approximately two seconds. Any zones that
are still hot to the touch will display an " " or " ".
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 turn on the booster function, touch the cooking zone
selector (9) for the desired zone, set the heat setting to "9" using the
"+" sensor (6) and then touch the "+" sensor (6) once more. "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 cancel the booster at any time, select the cooking zone using
the cooking zone selector (9) and lower the heat setting using the
"-" sensor (8).

11
Please note: The booster function cannot be used on two vertically
arranged cooking zones at the same time. This is to prevent damage
to the internal modules caused by overheating.
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 function remains active and 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 12.

Auto-heat function
•Every zone is equipped with an auto-heat function, which reduces
the warming up time for the zone. To turn on the auto-heat function,
touch the cooking zone selector (9) for the required zone, then set
the desired heat setting using the "+" sensor (6).
•With the cooking zone indicator (7) still pulsating, touch the cooking
zone selector (9) for that zone for approximately one second. The
display will alternate between the set power level and “A” for a
preset period of time, before reducing the power to the originally
selected heat setting.
• To disengage the auto-heat function simply select the zone using
the cooking zone selector (9) and then press the cooking zone
selector (9) again for approximately one second.

13
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. The timer can also
be used as a minute minder to count down time, when the zones are
not in use.
To set the timer
•First switch on the hob and set the desired zone to the power level
required.
•Whilst the relevant cooking zone indicator (7) is pulsating touch
the timer sensor (10). Using the higher heat setting selector (6) or
the lower heat setting selector (8), set the desired cooking time
(in minutes) to between 0 and 99. The selection will confirm in
approximately 2 seconds, the timer display will show the time set
and the countdown will start.
•If no time is set within ten seconds, the timer indicator light (12) will
become inactive and the zone will continue cooking.
At the end of the timer, the selected zone will switch o and the
timer display, and relevant time indicator light, will flash. The hob will
beep for approximately two minutes. To switch o the beep and the
flashing displays, touch any key. This beeping also occurs after the
minute minder time has elapsed and the same process to switch o
the beep applies.

14
Please note: The timer duration can be adjusted at any time during
the countdown. Simply touch the relevant cooking zone selector (9)
so that the zone indicator (7) pulsates, then press the timer sensor
(10) within 10 seconds and adjust the minutes using the higher (6) and
lower (8) heat setting selectors.
Please note: The power level can be adjusted at any time during the
countdown.
To cancel the timer
•Touch the cooking zone selector (9) for the required zone so that
the cooking zone indicator (7) pulsates. Touch the timer sensor (10)
and hold it for approximately 3 seconds.
Please note: Cancelling the timer will not switch o the zone. You
should switch the zone o manually if required.
To set the minute minder
The timer can also be used as a minute minder when the hob is not in
use.
• Switch the hob on using the on/o sensor (5).
• Touch the timer sensor (10) to activate the minute minder.
• Use the higher (6) and lower (8) heat setting selectors to set the
desired time in minutes.
To cancel the minute minder
• Touch and hold the timer sensor (10) for approximately 3 seconds.

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. 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. Then simply touch the desired
zone's selector (9) and set the power level using the "+" or "-"
selectors to " " (use the "+" selector to set the power level to 1 and
then use the "-" selector once).
• The keep warm function’s duration is limited to keep food as safe
as possible. This duration is detailed on page 12.
To deactivate the keep warm function
• Touch the desired zone's selector (9) and either set the power level
using the "+" or "-" selectors to "0" or, alternatively, touch and hold
the cooking zone selector for 3 seconds. The cooking zone
indicator will display a "0" to confirm that the zone is now inactive
but will display an " " or " " if the zone is still hot to the touch.
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 deactivated when the hob is turned on or o but not when
power has been switched o at, or the appliance disconnected from,
the mains.

16
Please note: Disconnecting the appliance from the mains will
deactivate the safety key lock.
To activate the safety key lock
To switch on the lock, turn on the hob and touch the safety key lock
sensor (11) for approximately 5 seconds. The safety key lock indicator
light (13) should illuminate.
To deactivate the safety key lock
To switch o the lock, touch the safety key lock sensor (11) for
approximately 5 seconds. The safety key lock indicator light (13)
should extinguish.
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 between 45°c and 60°c. An
“ ” will show if the relevant zone is 60°c or above. You should avoid
touching any zone whilst the hob is in use or whilst either residual
heat indicator is 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.

17
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 and choose an appropriate zone depending on the size of
the pan. 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.
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.
Zone Size Minimum Pan Size (mm) Maximum Pan Size (mm)
160-180mm 90 160-180
210-220mm 140 210-220

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 19.

Troubleshooting
If your hob does not appear to be working well:
Check with your installer, if you are at all unsure, as to what power
level the hob is configured to (page 26). Any power setting lower
than 7.4kW will implement the power management feature whereby
the hob powers zones in bursts to try and ensure even peformance
between all active zones. This means that 4 zones on full power on a
3.7kW power setting will not perform the same as said zones on full
power at 7.4kW.
IMPORTANT: Never reconfigure your hob’s power setting without
your installer or electrician present to confirm the fuse and cable
protecting the appliance and subsequently if it is safe to do so.
Consult page 27 for information.
