HOW TO SAVE ELECTRICITY
Using the electricity in a re-
sponsible manner not only
saves money, but also helps
protect the environment. So
let’s save electricity! This is
how it’s done:
●Use the correct cookware.
Cookware with at and a thick base can save
up to 1/3 of electricity. Please remember to
cover cookware with the lid, otherwise electri-
city 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 unneces-
sarily increased.

INSTALLATION
Connecting to electrical mains
Important!
Electrical connection must be made by a properly certied qualied installer. Do not
make any alterations in the appliance electrical system.
Tips for the installer
The hob is equipped with a terminal block allowing di󰀨erent connections appropriate for a
specic type of power supply.
Terminal block allows the following connections:
- single-phase 230 V ~
- two-phase 400 V 2N~
- three-phase 400 V 3N~
The hob can be adapted to a specic type of power supply by bridging the appropriate
terminals according to wiring diagram. Wiring diagram is placed on the hob's underside. The
terminal block can be accessed by removing the lid on hob's underside. Remember to match
the power cord to the type of connection and the hob's power rating.
Important!
Remember to connect the neutral lead to correct terminal block clamp, marked with
. The electrical system supplying the hob must be protected by a properly selected
tripping device or a circuit breaker allowing to disconnect the power supply in an
emergency.
Before connecting the appliance to power, please carefully read the information provided on
the rating plate and wiring diagram.
Connecting the hob other than shown on the wiring diagram may damage the hob.
CAUTION! The installer is obliged to provide the user with "appliance electrical connection
certicate" (enclosed with the warranty card). After installation, the installer should also provide
information on the connection made:
- single-phase, two-phase or three-phase,
- conductor cross-section,
- electrical protection (fuse type).

OPERATION
Before using the appliance for the rst time
● thoroughly clean your induction hob rst. 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 rst use.
● operate the appliance while observing all safety guidelines.
Induction cooking zone operation principle
Electric oscillator powers a coil placed inside the appliance.
This coil produces a magnetic eld, which induces eddy cur-
rents in the cookware.
These eddy currents induced by the magnetic eld cause the
cookware to heat up.
This requires the use of pots and pans whose base is ferromagnetic, in other words suscep-
tible to magnetic elds.
Overall, induction technology is characterized by two advantages:
●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.
Certain sounds can be heard during normal use of the induction hob, which do not a󰀨ect its
correct operation.
●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 di󰀨erent
materials at maximum heat setting. The noise intensies 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 di󰀨erent materi-
als. The noise intensity depends on how the food is cooked.
●Buzzing. Buzzing can be heard when electronics cooling fan operates.
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.

16
OPERATION
The high-quality cookware is an essential condition for e󰀩cient induction cooking.
Cookware characteristics.
●Always use high quality cookware, with perfectly at 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 lling 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 con-
sumption.
● To determine if cookware is suitable, make sure that its base attracts a magnet.
●Cookware base has to be at 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 exces-
sive 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 situ-
ation where it is not possible to uniformly distribute the heat
in the cookware. If the ferromagnetic area is reduced due to
inclusion of aluminium parts then the e󰀨ective heated area can
be reduced. Problems with the detection of the cookware 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
given cooking zone, it is advisable to try it in a smaller cooking
zone.
Select cookware for induction cooking

17
OPERATION
Marking of kitchen
cookware Check for marking indicating that the cookware is suitable for induction
cooking.
Use magnetic cookware (enamelled steel, ferrite sta-
inless steel, cast iron). The easiest way to determine
if your cookware is suitable is to perform the „magnet
test”. Find a generic magnet and check if it sticks to
the base of the cookware.
Stainless Steel Cookware is not detected
With the exception of the ferromagnetic steel cookwa-
re
Aluminium Cookware is not detected
Cast iron High e󰀩ciency
Caution: cookware can scratch the hob surface
Enamelled steel High e󰀩ciency
Cookware with a at, thick and smooth base is re-
commended
Glass Cookware is not detected
Porcelain Cookware is not detected
Cookware with copper
base
Cookware is not detected
For induction cooking us only ferromagnetic base materials such as:
●enamelled steel
● cast iron
● special stainless steel cookware designed for induction cooking.
Cookware size.
●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 reduce
the e󰀨ectiveness of the cooking zone and increase cooking time.
● Cooking zones have a lower pot detection limit that depends on the diameter of ferromag-
netic 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.

Disconnecting the appliance from electrical mains deactivates the Child
Lock.
Residual heat indicator "H"
When you have nished cooking, the induction hob glass within the cooking zone
is still hot, this is called residual heat.
If the glass temperature is higher than 60°C*, display of the cooking zone
shows "H".
If the glass temperature is 45°C* – 60°C), the cooking zone display shows
"h" (low residual heat).
* Temperatures are approximate
When residual heat indicator is on, do not touch the cooking zone as
there is a risk of burns and do not place on it any items sensitive to
heat!
The "H" or "h" residual heat indicator is not displayed during a power
outage. However, cooking zones may still be hot!
