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.

8
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 at 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 ashes, 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.

15
Ecient Use of Your Hob
The hob is equipped with zones of dierent sizes, designed to
accommodate most shapes and sizes of pan. For best results,
only use pans with at 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.

IMPORTANT:
When correctly installed, your product meets all safety
requirements laid down for this type of product. However, special
care should be taken around the rear or the underneath of the
appliance as these areas are not designed or intended to be
touched and may contain sharp or rough edges that could cause
injury.
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 ow freely to the air
intake, from the air outlet and in the base and run of units into which
it is installed (Fig 3). 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

20
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
the hood above the hob must be at least 600mm (650mm is
recommended) (Fig. 4). If the instructions supplied with the hood
dictate that the hood must be installed at a height greater than
600mm, then that height is the minimum required.
Wall furniture requirements:
The minimum height of any cabinet immediately above the hob is
900mm. The minimum height of any adjacent units (including light
pelmets) is 400mm, unless they are manufactured from a material
resistant to fire (steel, for example).
Notes:
•Do not position this appliance above a refrigeration unit. The heat
generated may cause the refrigeration unit to fail.
•This appliance is designed to be installed into cabinet units capable
of withstanding temperatures of 65°C or greater above ambient
temperature.
•Never place perishable foods, soft items such as tea towels,
cleaning products or ammable items in the cupboard or drawer
below the appliance.
•If an oven is to be installed below the hob, the thermal safety system
