IMPORTANT INFORMATION FOR CORRECT DISPOSAL OF THE
PRODUCT IN ACCORDANCE WITH EC DIRECTIVE 2002/96/EC.
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 ensure children cannot reach 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.

5
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 so cooking more evenly.
Most cookware is compatible with induction cooking. There are three
ways to check the suitability of your cookware:
1. Use 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 switched on to power
level 4: If the display remains on, then the cookware is
compatible. If the display flashes, 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.

Residual heat indicators
The hob is equipped with residual heat indicators to warn when any
of the zones are still hot to the touch after cooking. An “H” will show
in the relevant zone display after cooking until the zone is at a safe
temperature to touch.
In the event of a power cut, the residual heat indictors will illuminate
after the power supply is restored. However, when there is no power
supply to the hob the residual heat indicators will not work, so extra
care must be taken.
Please note:
You should avoid touching the zones when the hob is in use, or when
an “H” is showing on the zone display.
Small object safety
Anything left on the control panel (e.g. cutlery or towels) will cause
the hob to switch o automatically and there will be a beep every ten
seconds until the obstruction is removed.
Pan detection
The hob is equipped with a sensor that will advise when the pan is

15
removed from the zone, or is unsuitable for use on induction hobs.
The zone display will show “U” alternating with the power level until
a suitable pan is placed on the zone. The zone will switch o after
approximately one minute if no suitable pan is placed on the zone.
Safety cutout
The hob is equipped with a safety switch that automatically switches
o zones after they have been operating for a certain period of time.
The time before this is activated is dependent on the power level
being used:

Fitting the Hob
Unpacking the hob:
Take care not to lose or mishandle any parts.
Fitting position of the hob:
This appliance must be installed a minimum of 50mm from any
back wall and a minimum of 180mm away from any adjacent vertical
surfaces, e.g. a tall cupboard end panel. This may be reduced to
100mm if the adjacent surface is resistant to fire (tiles or steel, for
example). These dimensions are shown in Fig. 5.
Ventilation requirements:
This appliance must be installed to allow air to flow freely to the air
intake, from the air outlet and in the base and run of units into which it
is installed (Fig 3). An air gap of 20mm is recommended immediately
below the hob.
Failure to allow sucient ventilation could cause damage to the hob
and constitutes incorrect installation, which is not covered by the
warranty.
Notes:
•This could be a simple slot cut out of the plinth, or a dedicated
ventilation grille.
•The furniture top rail should not be fitted to the unit. This allows the
induction hob to exhaust air into the kitchen space.
•The recommended ventilation sizes are for guidance only.
If tting a cooker hood above the hob:
If a cooker hood is to be installed above the hob, the height of
