HOW TO SAVE ELECTRICITY
UNPACKING
DISPOSAL
Using the electricity in a responsible manner not only saves money, but also helps protect
the environment. So let’s save electricity! This is how it’s done:
The appliance was protected from damage at the time of transport. After unpacking, please
dispose of all elements of packaging in a way that will not cause damage to the environ-
ment. All materials used for packaging the appliance are environmentally friendly; they are
100%recyclableandaremarkedwiththeappropriatesymbol.
This marking means that the appliance must not be disposed of together with other house-
hold waste after it has been used. The user is obliged to hand it over to waste collection
centre collecting used electrical and electronic goods.
The collectors, including local collection points, shops and local authority departments
providerecyclingschemes.Properhandlingofusedelectricalandelectronicgoodshelps
avoid environmental and health hazards resulting from the presence of dangerous compo-
nents and the inappropriate storage and processing of such goods
Important! Keep the packaging material (bags, Styrofoam pieces, etc.) out of reach of
children during unpacking.
InaccordancewithEuropeanDirective2012/19/UEandPolishlegislationregardingused
electrical and electronic goods, this appliance is marked with the symbol of the crossed-out
waste container.
•●Use the correct cookware
Cookwarewithflatandathickbasecansaveupto1/3ofelectricity.Pleaserememberto
cover cookware with the lid, otherwise electricity consumption increased four times!
•Always keep the cooking zones and cookware bases clean.
Dirt prevents proper heat transfer. Often burnt stains can be removed only with agents
harmful to the environment.
•●Avoiding unnecessary lifting the lid to peek into the pot.
•Do not install the hob in the immediate vicinity of refrigerator / freezer.
The electricity consumption is then unnecessarily increased.

OPERATION
Before using the appliance for the first time
Induction cooking zone operation principle
Electric oscillator powers a coil placed inside the appliance. This coil produces a magnetic
field, which induces eddy currents in the cookware. These eddy currents induced by the
magnetic field cause the cookware to heat up.
This requires the use of pots and pans whose base is ferromagnetic, in other words sus-
ceptible to magnetic fields.
Overall, induction technology is characterized by two advantages:
Certainsoundscanbeheardduringnormaluseoftheinductionhob,whichdonotaffect
its correct operation.
The noises that can be heard during the normal appliance operation are the result of the
cooling fan operation, cooking method, cookware dimensions, cookware material and the
heat setting. These noises are normal and do not indicate a fault.
••thoroughlycleanyourinductionhobfirst.Theinductionhobshouldbetreatedwiththe
same care as a glass surface.
••switchontheventilationintheroomoropenawindow,astheappliancecouldemitan
unpleasant smell during first use.
••operatetheappliancewhileobservingallsafetyguidelines.
•the heat is only emitted by the cookware and its use is maximised,
•there is no thermal inertia, since the cooking starts immediately when the pot is placed
on the hob and ends once it is removed
••Low-frequencyhumming.Thisnoiseariseswhenthecookwareisemptyandstops
when water is poured or food is placed in the cookware.
••High-frequencywhizz.Thisnoisearisesincookwaremadeofmultiplelayersofdiffer-
ent materials at maximum heat setting. The noise intensifies when using two or more
cooking zones at maximum heat setting. The noise will stop or reduce when heat
setting is reduced.
••Creakingnoise.Thisnoisearisesincookwaremadeofmultiplelayersofdifferentma-
terials. The noise intensity depends on how the food is cooked.
••Buzzing.Buzzingcanbeheardwhenelectronicscoolingfanoperates.

13
OPERATION
Pan detector
Pandetectorisinstalledininductionhobs.Pandetectorstartsheatingautomaticallywhen
a pan is detected on a cooking zone and stops heating when it is removed. This helps save
electricity.
The induction hob is equipped with electronic touch control sensor fields, which are op-
erated by touching the marked area with a finger. Each time a sensor field is touched, an
acoustic signal can be heard.
•When a suitable pan is placed on a cooking zone, the display shows the heat setting.
••Inductionrequirestheuseofsuitablecookwarewithferromagneticbase(seeTable).
If a pan is not placed on a cooking zone or the pan is unsuitable, the symbol
isdisplayed.Thecookingzonewillnotoperate.Ifapanisnotdetectedwithin10
minutes, the cooking zone will be switched off. Switch off the cooking zone using the
touch control sensor field rather than by removing the pan.
When switching the appliance on or off or changing the heat setting, attention should
be paid that only one sensor field at a time is touched. When two or more sensor
fields are touched at the same time (except timer and child lock), the appliance ig-
nores the control signals and may trigger a fault indication if sensor fields are touched
for a long time. When you finish cooking switch off the cooking zone using touch
control sensor fields and do not rely solely on the pan detector.
Pan detector does not operate as the on/off sensor.
The protective device:
If the hob has been installed correctly and is used properly, any protective devices are rarely
required.
Fan: protects and cools controls and power components. It can operate at two different
speeds and is activated automatically. Fan runs until the electronic system has sufficiently
cooled down regardless of the appliance or the cooking zones being turned on or off.
Temperature sensor: Temperature of electronic circuits is continuously monitored by a
temperature sensor. If temperature is raised beyond a safe level, this protection system will
reduce cooking zone heat setting or shut down the cooking zones adjacent to the over-
heated electronic circuits.
Pan detection: allows the hob to detect pans placed on a cooking zone. Small objects
placed on the cooking zone (eg, spoon, knife, ring ...) will not be recognised as pans and
the hob will not operate.

14
OPERATION
The high-quality cookware is an essential condition for efficient induction
cooking.
Cookware characteristics
Select cookware for induction cooking
••Alwaysusehighqualitycookware,withperfectlyflatbase.Thispreventstheformation
oflocalhotspots,wherefoodmightstick.Potsandpanswiththicksteelwallsprovide
superior heat distribution.
••Makesurethatcookwarebaseisdry:whenfillingapotorwhenusingapottakenout
of the refrigerator make sure its base is completely dry before placing it on the cooking
zone. This is to avoid soiling the surface of the hob.
••Lidpreventsheatfromescapingandthusreducesheatingtimeandlowersenergy
consumption.
••Todetermineifcookwareissuitable,makesurethatitsbaseattractsamagnet.
•●Cookware base has to be flat for optimal temperature control by the induction
module.
•●The concave base or deep embossed logo of the manufacturer interfere with
the temperature induction control module and can cause overheating of the pot
or pan.
•●Do not use damaged cookware such as cookware with deformed base due to
excessive heat.
•When you use large ferromagnetic base cookware,
whose diameter is less than the total diameter of the
cookware, only the ferromagnetic base heats up.
This results in a situation where it is not possible to
uniformly distribute the heat in the cookware. If the
ferromagnetic area is reduced due to inclusion of al-
uminium parts, then the effective heated area can be
reduced.Problemswiththe detectionof thecook-
ware could arise or cookware may not be detected at
all. To achieve optimum cooking results, the diameter
of the ferromagnetic base should match that of the
cooking zone. If cookware is not detected in a giv-
en cooking zone, it is advisable to try it in a smaller
cooking zone.

Use magnetic cookware (enamelled steel, ferrite stainless
steel, cast iron). The easiest way to determine if your cook-
wareissuitableistoperformthe•magnettest”.Findagener-
ic magnet and check if it sticks to the base of the cookware.

•In order to achieve best cooking results, use cookware with bottoms (ferromagnetic
part) of the size corresponding to the size of the cooking zone.
••Usingcookwarewiththebottomdiametersmallerthanthecookingzonesizewillre-
duce the effectiveness of the cooking zone and increase cooking time.
••Cookingzoneshavealowerpotdetectionlimitthatdependsonthediameteroffer-
romagnetic part of the pot bottom and the pot material. The use of an unsuitable pot
might lead to pot being undetected by a cooking zone.

Booster function
After selection of a respective cooking zone, the boost function can be activated by select-
ingthepowerlevel9andthenpressingPLUS(3)button.Bymeansofthisfunctioncertain
cooking zones are enabled to receive power over the nominal (the number of boostable
cooking zone depends on the power available on a partial modules which is to be lees than
total hob power ). If the desired cooking zone has the capacity to activate the booster, the
displayshowsa“P“symbol.Incasetheavailablepowerisnotenoughthecookingstage
display•ashesfor3secondsonthecookingzonewhichneedstobereducedandwhich
requires automatic adjustment.
The boosting time is limited to 5 min to protect cooking utensils. After the booster is
switchedoffautomatically,thecookingzonecontinuesoperationonpowerlevel“9”.The
booster can be reactivated after some minutes.
In case that the pan is removed from the cooking zone during boosting, the boosting func-
tion remains active and boosting time continues.
The power management is based on on the principle that the last entry is requested by the
induction as top priority. That means that previous actions and settings also made for the
other cooking zones are reversed automatically, if necessary.
-If induction identi•es the necessityof reducing power at a cookingzone, the selected
cookingstage•ashesonthatcookingzoneprovidingacorrectionperiodof3secbeforethe
power is reduced automatically to a minimum cooking stage.
- If the setting is adjusted within the correction period, the power management checks the
settings again. Should a new setting lead to further power reduction, the correction period
starts again.
-Ifnoautomaticcorrectionneedsbeingmadetothecookingzonesetting,the•ashing
stops immediately and the original value remains as a steady display indication. Should the
situation change again on the power reduced cooking zone, no automatic power increase
is effected.
NOTE: When selecting the Booster function on any of the rear areas (left or right), the front
area located on the same side will automatically switch off (if it was already switched on)
in order to focus all the power on the rear area. This allows you to benefit from an extra
powerfulBooster.However,whenselectingtheBoosterfunctiononanyofthefrontareas
(left or right), the rear area located on the same side may be operated up to power level 8,
as it will not require as much energy input.

Dependent on the selected setting, every cooking zone will be switched off after a defined
maximum operation time if no operation of the assigned cooking zone follows within this
timeperiod.Everychangeofthecookingzonecondition(bymeansofthePLUS-,MINUS-
key) puts back the maximum operation time of this cooking zone to the initial value of the
operating time limitation.
•-Iftheelectroniccontrolrealizesacontinuousoperationofkeysforapprox.10seconds,it
switchesOFFautomatically.Thecontrolsendsoutanaudiblefailuresignalfor10seconds,
so that the user can remove the object which has been mistakenly placed onto the oper-
ationsurface.Thedisplaysshowthefailurecode“ER03“.Ifthefailurecarriesonfor
morethan10seconds,onlythecode“ER03“willbedisplayedaslongasthefailurewill
berecognizedbytheelectroniccontrol.Ifthecookingzoneisinthe“hot”status,“H“will
appear on the display in alteration with the failure notice.
•-Ifnocookingzonewillbeactivatedwithin20secondsafterswitching-ONbymeansof
thePower-key,thecontrolswitchesbackfromtheON-conditionintothestand-by-mode.
•-Whenthecontrolisswitched-ONtheON/OFF-keyhaspriorityoverallotherkeys,sothat
the control can be switched-OFF anytime, even in case of multiple or continuous operation
of keys.
•-Inthestand-bymodeacontinousoperationwillnotbesignalized.However,beforethe
electronic control can be switched-ON again, it has to recognize that all keys are not op-
erated.
