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.

Switching a cooking zone on/off
After mains voltage is applied, the touch control initialises for approximately one second
before it is ready for use.
All displays and LEDs flash for approximately one second after resetting. Once this period
is complete, all displays and LEDs switch off and the touch control is in standby mode.
PresstheON/OFF(1)buttontoswitchthetouchcontrolon.
Thecookingzonedisplays indicate“0“.If acookingzone isin“hot“ (hightemperature)
mode,thedisplaywillalternatelyindicate“H“and“0“.
Afterswitchingthetouchcontrolon,itwillremainactivefor20seconds.Ifnocookingzone
is selected, the touch control automatically switches back to standby mode.
ThetouchcontrolcanonlybeswitchedonbypressingtheON/OFF(1)button.
PressingtheON/OFF(1)buttonatthesametimeasotherbuttonswillhavenoeffectand
the touch control will remain on standby.
ThetouchcontrolcanbeswitchedoffatanytimeusingtheON/OFF(1)button.Thisiseven
the case when the control has been locked by the child safety feature.
TheON/OFF(1)buttonalwaystakespriorityintheswitchingofffunction.
Touch sensitive keys All operations can be performed using touch sensitive keys (capacitive
sensors) located on the front of the control board; each key has a corresponding display.
All actions are confirmed by an audible signal.
Onceswitchedon,thetouchcontrolautomaticallyswitchesoffafter20secondsofinactiv-
ity.Afterselectingacookingzone,theautomaticofftimeisdividedinto10seconds,after

be switched off.
Thecookingzonecanbesetto9levelsthatareindicatedbythenumbers“1“to“9“onthe
sevensegment LED displays (6).
This informs the user that the glass is at a dangerous temperature in the event of touching
the area located around the cooking zone. The temperature is determined by a mathemat-
icalmodelandanyresidualheatisindicatedbya“H”onthecorresponding7-segment
display.
Heatingandcoolingarecalculatedbasedon:
-Theselectedsettinglevel(between“0“and“9“)
-TheON/OFFtime.Afterswitchingoffthecookingzone,thecorrespondingdisplaywill
indicate“H”untilthetemperatureinthezonehasdroppedbelowthecriticallevel(≤60•C).
In terms of the setting level, if no operation occurs each cooking zone switches off after an
established maximum time.
Eachoperationinthecookingzonecondition(usingthePLUS(3)andMINUS(2)ordual
zone) restarts the maximum operating time of the zone by resetting it to its initial value.

CLEANING AND MAINTENANCE
Properroutinemaintenanceandcleaningoftheappliancecansignificantlyextenditstrou-
ble-free operation.
When cleaning induction hobs, the same principles apply as for glass surfaces. Do not use
under any circumstances any abrasive or caustic cleaners or scouring powders or pads!
Do not use steam or pressure cleaners
Never apply a detergent on the hot cooking zone. It is best to let the cleaner dry and then
wipe it wet. Any traces of the detergent should be wiped off clean with a damp cloth before
re-heating. Otherwise, it can be corrosive.
Warranty will be void if you do not follow the above guidelines!
Removing stains
Cleaning after each use
••Wipe light stains with a damp cloth without
detergent. The use of dishwashing liquid may
cause a bluish surface discolouration. These
persistent stains cannot always be removed
right away, even using a special cleaner.
••Firmlyadheringdirtcanbecarefullyremoved
with a scraper. Then wipe the cooking surface
with a damp cloth.
••Brightstainsofpearlcolour(residualaluminium)canberemovedfromthecoolhob
using a special cleaning agent. Limestone residue (eg. after evaporated water) can be
removed by vinegar or a special cleaning agent.
••Donotturnoffthecookingzonewhenremovingsugar,foodcontainingsugar,plastic
and aluminium foil. Immediately and thoroughly scrape the leftovers off the hot cooking
zone using a sharp scraper. Once the bulk of the stain is removed the hob can be turned
off and clean the cooled off cooking zone with a special cleaning agent. Special cleaners
are available in supermarkets, electrical and home appliance shops, drug stores, as well
as retail food shops and kitchen showrooms. Scrapers can be purchased in DIY and
construction equipment stores, as well as in shops carrying painting accessories.
