INFO  The BORA induction wok pan HIW1 is ideal for the 
induction wok cooktop CKIW and is available as 
an accessory.
 Perform a magnet test, if necessary. If a magnet sticks 
to the base of the utensils, they are normally induction 
compatible.
 Pay attention to the cookware bottom. The base of 
the cookware should not show any sign of curvature 
(exception: wok cooktop CKIW). Due to incorrect 
temperature monitoring of the hob caused by the 
air gap between the cookware and the temperature 
sensor underneath the hob, overheating may occur. 
The bottom of the cookware must not have any 
sharp grooves or sharp edges to avoid scratching the 
cooktop.
 Place the cookware (without a mat or similar) directly 
onto the glass ceramic.
Noises
The following noises may occur in the cookware when 
using induction cooking zones, depending on the material 
and the finish of the base:
Humming may occur when using a high power level. 
It decreases or disappears if the power level is 
decreased.
Crackling or whistling may occur due to the bases 
of cookware being made of different materials (e.g. 
sandwich base).
Clicking sounds may occur during electronic switching 
procedures especially at low power levels.
Whirring may occur when the cooling fan is switched 
on. In order to increase the service life of the 
electronic system, the cooktop is equipped with a 
cooling fan. The cooling fan switches on automatically 
if the cooktop is used intensively. You will hear a 
whirring sound. The cooling fan may continue to run 
after the appliance has been switched off.
4.3.5  How the Hyper and HiLight cooktops 
work (CKCH, CKCB)
Under the cooking zone is a radiant heating element with 
a heating tape. When the cooking zone is switched on, 
the heating tape generates radiant heat, which radiates to 
the cooking zone and heats it up.
Power levels
The high power output of induction cooktops results 
in the very quick heating up of cookware. A slight 
adjustment is needed in comparison to conventional 
cooking systems when selecting the power level in order 
to avoid burning food.
