9 IMPORTANT SAFETY INSTRUCTIONS
READ AND SAVE THESE INSTRUCTIONS
Burn Prevention
DO NOT TOUCH SURFACE UNITS OR AREAS NEAR
UNITS - Surface units may be hot even though they are
dark in color. Areas near surface units may become hot
enough to cause burns. During and after use, do not
touch, or let clothing, potholders, or other flammable
materials contact surface units or areas near units until
they have had sufficient time to cool. Among these areas
are the cooktop and areas facing the cooktop.
Do not heat or warm unopened food containers. Build-up
of pressure may cause the container to burst and cause
injury.
Always use dry potholders. Moist or damp potholders on
hot surfaces may result in burns from steam. Do not let
potholder touch hot heating elements. Do not use a towel
or other bulky cloth.
Always turn hood ON when cooking at high heat or when
flambeing food (i.e. Crêpes Suzette, Cherries Jubilee,
Peppercorn Beef Flambe).
Use high heat settings on the cooktop only when
necessary. To avoid bubbling and splattering, heat oil
slowly on no more than a low-medium setting. Hot oil is
capable of causing extreme burns and injury.
Never move a pan of hot oil, especially a deep fat fryer.
Wait until it is cool.
Secure all loose garments, etc. before beginning. Tie
long hair so that it does not hang loose, and do not wear
loose fitting clothing or hanging garments, such as ties,
scarves, jewelry, or dangling sleeves.
WARNING
RISK OF BURNS
Metallic objects become hot very quickly on the cooktop.
Never set down metallic objects, such as knives, forks,
spoons and lids on the cooktop.
WARNING
RISK OF BURNS
The pan detection may potentially fail to turn off the
cooking zone due to spilled food or objects placed upon
the cooktop. After each use, turn off the cooktop using
the main switch.
If the display does not work when a cooking area is
heating up, disconnect the circuit breaker or fuse in the
electrical panel. Contact an authorized servicer.
Child Safety
When children become old enough to use the appliance,
it is the responsibility of the parents or legal guardians to
ensure that they are instructed in safe practices by
qualified persons.
Do not allow anyone to climb, stand, lean, sit, or hang on
any part of an appliance, especially a door, warming
drawer, or storage drawer. This can damage the
appliance, and the unit may tip over, potentially causing
severe injury.
Do not allow children to use this appliance unless closely
supervised by an adult. Children and pets should not be
left alone or unattended in the area where the appliance
is in use. They should never be allowed to play in its
vicinity, whether or not the appliance is in use.
CAUTION
Items of interest to children should not be stored in an
appliance, in cabinets above an appliance or on the
backsplash. Children climbing on an appliance to reach
items could be seriously injured.
Cleaning Safety
Do not clean the appliance while it is still hot. Some
cleaners produce noxious fumes when applied to a hot
surface. Wet clothes and sponges can cause burns from
steam.
Do not use steam cleaners to clean the appliance.
Cookware Safety
Hold the handle of the pan when stirring or turning food.
This helps prevent spills and movement of the pan.
Use Proper Pan Size.
The use of undersized cookware will expose a portion of
the heating element or burner to direct contact and may
result in ignition of clothing. Select cookware having flat
bottoms large enough to cover the surface heating unit.
This appliance is equipped with one or more surface
units of different size. Proper relationship of cookware to
heating element or burner will also improve efficiency.
Cookware not approved for use with ceramic cooktops
may break with sudden temperature changes. Use only
pans that are appropriate for ceramic induction
cooktops.
Always position handles of utensils inward so they do not
extend over adjacent work areas, burners, or the edge of
the cooktop. This reduces the risk of fires, spills and
burns.
WARNING
RISK OF INJURY
When cooking with a bain-marie, the cooktop and
cooking vessel may crack due to overheating. The
cooking vessel in the bain-marie must not come in direct
contact with the bottom of the pot filled with water. Use
only heat-resistant cookware.

Electromagnetic interference
WARNING
This induction cooktop generates and uses ISM
frequency energy that heats cookware by using an
electromagnetic field. It has been tested and complies
with Part 18 of the FCC Rules for ISM equipment. This
induction cooktop meets the FCC requirements to
minimize interference with other devices in residential
installation. Induction cooktops may cause interference
with television or radio reception. If interference occurs,
the user should try to correct the interference by:
▯ Relocating the receiving antenna of the radio or
television.
▯ Increasing the distance between the cooktop and the
receiver.
▯ Connecting the receiver into an outlet different than the
receiver.
It is the user’s responsibility to correct any interference.
CAUTION
Persons with a pacemaker or similar medical device
should exercise caution when standing near an induction
cooktop while it is in use. Consult your doctor or the
manufacturer of the pacemaker or similar medical device
for additional information about its effects with
electromagnetic fields from an induction cooktop.
Cooling fan
The cooktop is equipped with a cooling fan on its
underside. Should the cooktop lie above a drawer, there
must be no objects or paper in it. They may be sucked in

Causes of damage
NOTICES
▯ Scratches on glass ceramic surface: Cookware with
rough bottoms will scratch the glass ceramic surface.
▯ Salt, sugar and sand: Salt, sugar or grains of sand will
scratch the glass ceramic surface. Never use the
cooktop as a working surface or for setting things
down.
▯ Overheated cookware: Avoid heating pots or pans
that are empty.
▯ Hot cookware: Never set down hot pans and pots on
the control panel or frame. This may cause damage.
Protecting the environment
Energy-saving advice
▯ Always place a fitting lid on cookware. Cooking with
an uncovered pan will result in a four-fold increase in
energy use. Use a glass lid to provide visibility and
avoid having to lift the lid.
▯ Use cookware equipped with a solid, flat bottom.
Curved pan bases increase energy consumption.
▯ The diameter of the pan base must match the size of
the element. If not, energy may be wasted. Note: The
manufacturer normally indicates the pan's upper
▯ Hard and sharp objects: Hard or sharp objects falling
on the cooktop may damage it.
▯ Boiled-over food: Sugar and products containing
sugar may damage the cooktop. Immediately eliminate
spills of these products with a glass scraper.
▯ Foils and plastics: Aluminum foil and plastic will melt
on the hot cooking zones. Stove protective film isn't
suitable for your cooktop.
▯ Unsuitable cleaning agent: Shimmering metallic
discolorations on the glass ceramic surface result from
the use of inappropriate cleaning agents and abrasion
from cookware.
diameter. This is normally greater than the diameter of
the pan's base.
▯ Choose cookware of a size suited to the amount of
food you are going to cook. A large pan that is only
half full will use a lot of energy.
▯ Use a small amount of water when cooking. This
saves energy, and vegetables retain a larger
percentage of their vitamins and minerals.
▯ Select a lower power level.
Cooking with Induction
Advantages of induction cooking
Induction cooking is very different from traditional
cooking methods, as heat builds up directly in the item of
cookware. This offers numerous advantages:
▯ Saves time when boiling and frying.
▯ Saves energy.
▯ Easier to care for and clean. Spilled food does not
burn on as quickly.
▯ Heat control and safety – the cooktop increases or
decreases the heat supply as soon as the user
changes the setting. The induction element stops the
heat supply as soon as the cookware is removed from
the element, without having to switch it off first.
Cookware
Only use ferromagnetic cookware for induction cooking,
such as:
▯ Cookware made from enameled steel
▯ Cookware made from cast iron
▯ Special induction-compatible cookware made from
stainless steel.
To check whether your cookware is suitable for induction
cooking, refer to the section on ~ "Suitability test of
cookware".
To achieve a good cooking result, the ferromagnetic area
on the base of the pan should match the size of the
element. If a element does not detect an item of
cookware, try placing it on another element with a
smaller diameter.
FP
LQ LQ LQ
FP
FP
8
Some induction cookware does not have a fully
ferromagnetic base:
▯ If the base of the cookware is only partially
ferromagnetic, only the area that is ferromagnetic will
heat up. This may mean that heat will not be
distributed evenly. The non-ferromagnetic area may
not heat up to a sufficient temperature for cooking.
▯ The ferromagnetic area will also be reduced if the
material of which the base of the cookware is made
contains aluminum, for example. This may mean that
the cookware will not become sufficiently hot or even
that it will not be detected.
No pan or improper size
If no pan is placed on the selected element, or if it is
made of unsuitable material or is not the correct size, the
power level displayed on the element indicator will flash.
Place a suitable pan on the element to stop the flashing.
If you take longer than 90 seconds to place a suitable
pan on the element, it will automatically turn off.
Empty pans or pans with a thin base
Do not heat up empty pans, or use pans with a thin base.
The cooktop is equipped with an internal safety system.
However, an empty pan may heat up so quickly that the
"automatic switch off" function may not have time to react
and the pan may reach very high temperatures. The pan
base could melt and damage the cooktop glass. In this
case, do not touch the pan and switch the cooktop off. If
the cooktop fails to work after it has cooled down, please
contact the technical service.
Pan detection
Each element has a lower limit for pan detection. This
depends on the diameter of the ferromagnetic area of the
cookware and the material of which its base is made. For
this reason, you should always use the element that best
matches the diameter of the base of the pan.
Unsuitable cookware
Do not ever use adapter plates for induction or cookware
made of:
▯ Traditional stainless steel
▯ Glass
▯ Clay
▯ Copper
▯ Aluminum
Properties of the base of the cookware
The material(s) of which the base of the cookware is
made can affect the cooking result. Using pots and pans
made from materials that distribute heat evenly through
them, such as stainless-steel pans with a three-layer
base, saves time and energy.
Use cookware with a flat base; if the base of the
cookware is uneven, this may impair the heat supply.
Automatic detection in double and triple cooking zones
These cooking zones can detect cookware of different
sizes. Depending on the material and the properties of
the cookware, the cooking zone automatically activates
the singe, double or triple cooking zone, supplying the
proper power to obtain good cooking results.

SpeedBoost® function
The SpeedBoost® function can be used to heat large
amounts of water faster than by using heat level Š.
Limitation on use
This function can always be activated for an element,
provided the other element in the same group is not in
use (see illustration). Otherwise, › and Š will flash in the
display for the selected element; heat setting Š will then
be set automatically without activating the function.
Advantages when frying
▯ The element only heats up if this is required to
maintain the temperature. This saves energy and
prevents the oil or fat from overheating.
▯ The AutoChef
®
function reports when the empty frying
pan has reached the optimum temperature for adding
oil and then for adding the food.
9 CAUTION
▯ Never leave oil or fat cooking unattended.
▯ Place the pan in the centre of the element. Make
sure that the base of the pan has the proper
diameter.
▯ Do not cover the pan with a lid. The automatic
regulation will not work. A mash splatter guard
can be used without affecting the automatic
regulation.
▯ Only use fat or oil that is suitable for frying. When
you are using butter, margarine, olive oil or pork
lard, select the min temperature setting.
▯ AutoChef
®
is not suitable for boiling.

Suitable pans for AutoChef
Suitable frying pans for use with AutoChef® are available
as optional accessory. Only use pans that are suitable for
use with AutoChef

. You can buy our system pans in
specialized stores, or through our Technical Assistance
Service. Always indicate the related reference code.
▯ HEZ390210 (Small)
▯ HEZ390220 (Medium)
▯ HEZ390230 (Large)
The frying pans have a non-stick coating, which means
that very little oil is needed for frying.

9 CAUTION
▯ The AutoChef
®
function was set especially for this
type of frying pan.
▯ Other frying pans may overheat. The temperature
can be set higher or lower. Try the lowest heat
setting first and then change it according to your
requirements.

Cleaning charts
Type of Soil Possible Solution
Dry sugar, sugar syrup, milk or tomato spills. Melted
plastic film or foil. All these items REQUIRE IMMEDIATE
REMOVAL. Failure to remove these immediatly can permanently damage the surface.
Remove these types of spills while the surface is hot
using the razor blade scraper. Use a new, sharp razor in
the scraper. Remove pan and turn off the element. Wearing an oven mitt, hold scraper at 30° angle, using care
not to gouge or scratch the glass. Push soil off the
heated area. After the surface has cooled, remove the
residue and apply the glass ceramic cooktop cleaner.
9 WARNING
RISK OF INJURY
The blade is extremely sharp. Risk of cuts. Protect
the blade when not in use. Replace the blade immediately when any imperfections are found. Follow
manufacturer’s instructions.
Burned-on food soil, dark streaks, and specks Soften by laying a damp paper towel or sponge on top of
soil for 30 minutes. Use a plastic scrubber and glass
ceramic cooktop cleaner or use the razor blade scraper.
Rinse and dry.
Greasy spatters Use a soapy sponge or cloth to remove grease; rinse
thoroughly and dry. Apply glass ceramic cooktop
cleaner.
Metal marks: Iridescent stain Pans with aluminum, copper or stainless steel bases may
leave marks. Treat immediately after surface has cooled
with glass ceramic cooktop cleaner. If this does not
remove the marks, try a mild abrasive (Bon Ami®, Soft
Scrub® without bleach) with a damp paper towel. Rinse
and reapply glass ceramic cooktop cleaner. Failure to
remove metal marks before the next heating makes
removal very difficult.
Hard water spots:
Hot cooking liquids dripped on surface
Minerals in some water can be transferred onto the surface and cause stains. Use undiluted white vinegar, rinse
and dry. Recondition with glass ceramic cooktop cleaner.
Remove boilovers and stains before using the cooktop
again.

Small scratches are common and do not affect cooking.
They become smoother and less noticeable with daily use
of the glass ceramic cooktop cleaner.
Apply glass ceramic cooktop cleaner before using to
remove sand-like grains and grit such as salt and seasoning. Scratches can be reduced by using pans with
bases that are smooth, clean, and dry before use. Use
recommended glass ceramic cooktop cleaner daily.
NOTICE: Diamond rings may scratch the surface.
Maintenance

Frequently-asked questions and answers
(FAQ)
Using the appliance
Why can't I switch on the cooktop and why is the child lock symbol lit?
The child lock is activated.
You can find information about this function in section ~ "Panel lock"
Why are the displays flashing and why can I hear an acoustic signal?
Remove any liquid or food remains from the control panel. Remove any objects from the control panel.
You can find instructions on how to deactivate the audible signal in the section on ~ "Basic settings"
Noises
Why I can hear noises while I'm cooking?
Noises may be generated while using the cooktop depending on the base material of the cookware. These
noises are a normal part of induction technology. They do not indicate a defect.
Possible noises:
A low humming noise like the one a transformer makes:
Occurs when cooking at a high heat setting. The noise disappears or becomes quieter when the heat setting is reduced.
Low whistling noise:
Occurs when the cookware is empty. This noise disappears when water or food is added to the cookware.
Crackling:
Occurs when using cookware made from different layers of material or when using cookware of different
sizes and different materials at the same time. The volume of the noise can vary depending on the quantity
of food being cooked or the cooking method.
High-pitched whistling noises:
Can occur when two elements are used on the highest heat setting at the same time. The whistling noises
disappear or become quieter when the heat setting is reduced.
Fan noise:
The cooktop is equipped with a fan that switches on automatically at high temperatures. The fan may continue to run even after you have switched off the cooktop if the temperature detected is still too high.
Cleaning
How do I clean the cooktop?
Using a special glass-ceramic cleaning agent produces the best results. We advise against using harsh or
abrasive cleaning agents, dishwater detergent (concentrated) or scouring pads.
