Hard and pointed objects
Hard or pointed objects may cause damage if they fall onto the hob
Spilt food
Sugar and other similar products may damage the hob.
These products should be removed immediately using a glass scraper.
Inappropriate cleaning products
Discolorations in the metal are caused by using unsuitable cleaning
products and wear as a result of contact with pans.
Plastic and foil
Aluminum foil and plastic containers will melt if placed on the hot areas
of the hob
Advice on saving energy
Use a pan with thick flat base. Curved bases
increase energy consumption.
Place a ruler on the base of the pan, if there are
no gaps, the base of the pan is completely flat.
The diameter of the base of the pan should
fit the size of the hotplate.
Check if the manufacturer has indicated the
upper diameter of the pan. In general, this is greater than the diameter of the
base of the pan.
If the diameter of the pan does not fit the diameter of the hotplate, you are
recommended to use a pan which is larger than the size of the hotplate, or
else about half the energy will be lost.
Choose pans which are the right size for the amount of food to be
prepared. A large pan which is half full will consume a lot of energy.
Always centre the pan on the hotplate and always cover the pan with the
matching lid. Cooking without using the lid quadruples energy consumption.
Cook using small amounts of water. This will save energy and will also
help green vegetables retain their vitamins and minerals.
During their cooking, food such as stews, soups may heat up too quickly
without any indication, spilling out of the cookware.
It is therefore advisable to heat this type of food gently, selecting a
suitable power level and stirring the contents before and during cooking. We
recommend not to use for Induction hob pots that have been used in a gas
hob fire can deform the flatness of bottom). In case of use, check that bottom
is flat.

Important notes
Safety in use is only guaranteed if the technical installation of the hob has
been carried out correctly and in accordance with the installation instructions.
The installation technician shall be liable for any damage cause as a result of
incorrect installation.
Only an authorized technician is able to connect the appliance. The
guidelines set out by the electricity provider must be observed.
This appliance should be used only with an earthed connection.
Using this appliance without an earthed connection or after it has been
incorrectly installated may, in very rare cases, cause serious harm.
The manufacturer accepts no responsibility for any malfunction or
damage which is caused by incorrect electrical installation.
If the appliance is not fitted with an accessible plug, disconnecting means
must be incorporated in the fixed installation, in accordance with the
installation regulations.
The power cable must be positioned so that it does not touch any of the
hot parts of the hob.
Refrigerators, dishwashers, ovens, or washing machines must not be
installed under the induction hob.
Any change to the appliance’s interior, including changing the power
cable, must be performed by the Customer Service.
Preparing the Kitchen
The worktop should be flat and horizontal. The aperture should be cut
before the appliance is installed. Remove any shavings, as these can affect
the operation of the electrical components. When the cutting has been
completed, the unit’s stability should be checked again.
Surfaces which have been cut should be sealed so that they are heat
resistant and so that they do not swell when moist.
The kitchen units to be fitted must resist temperatures of up to 90oC.
The gap between the aperture and the side wall must be at least: 40 mm.

Electric Induction hobs Chef’s EH-xxx330
10
It is not recommended that the hob be placed between two side walls but,
if this is the case, a gap of at least 200 mm should also be left on one side.
If the induction hob is installed above a sterilizer there must be a gap of
70 mm from the top of worktop to the top of the sterilizer.
If the induction hob is installed without sterilizer or above a drawer, the
worktop thick around the hob must be 20 mm as minimum.
If the interior width of the kitchen unit is less than 700 mm, a 80 mm –
long cut must be made in the side walls from the top section of the hob.
Taking into account the hob ventilation:
An aperture must be cut in the top section of the back of the kitchen unit,
680 mm wide and 45 mm high.
There must be a gap of 20 mm between the back of the kitchen unit and
the kitchen wall.
If the hob is installed above a drawer, allow a gap of 65 mm between the
drawer and the top section of the worktop.
Installing and connecting the hob
The earth wire ( green and yellow) should be connected first and
disconnected last. It should also be longer than the others, so that even if the
hob is moving the other wires can be disconnected before the earth wire.
Connection diagram ( see figure)
1. Brown
2. Blue
3. Green and Yellow
Is required 16A electrical installation at customer’s house (electrical
circuit, socket and fuse ).
Do not trap the lead during installation and do not guide it over sharp
edges.
The hob and the worktop should not be sealed with silicone as the hob
itself has a seal which serves this function.

Removing the hob
Disconnect the cooker from the power supply.
Push out the hob from below.
3. Induction cooking
Advantages of induction cooking:
- Greater speed in cooking and frying, as the pan is heated directly.
- Reduced energy consumption.
- Cleaner and easier to use; spilt food does not burn as much on the hob.
- Cooking control and safety; the hob supplies or cuts off the heat as soon
as the controls are operated. The Induction
hotplate stops supplying heat if the pan is
removed before the power has been
switched off.
Suitable pans
Ferromagnetic pans are the only pans which
are suitable for induction cooking. They can be
made of:
- enameled steel
- cast iron
- specially designed cookware for induction cooking made from stainless
steel
Special pans for induction cooking.
Other types of special pans are available for induction cooking, where the
base of the pan is not entirely ferromagnetic. Check the diameter as this
could affect the pan detection as well as the cooking results.
Checking pans using a magnet
To find out whether the pans are suitable, check that they are attracted to a
magnet.The manufacturer will usually indicate if their pans are suitable for
induction cooking.
Unsuitable pans. Never use pans made from:
- standard, high quality steel

Electric Induction hobs Chef’s EH-xxx330

- glass / earthenware
- copper / aluminum
Characteristics of the base of the pan
The characteristics of the base of the pan can
affect the evenness of the cooking.
Pans which are made from heat-diffusing
materials (such as “sandwich” pans made from
stainless steel) distribute the heat evenly, saving
time and energy.
No pan or incorrect size pan
If no pan is place on the hotplate, or the pan is not made of a suitable material
or it is not a suitable size, the heat setting on the hotplate indicator will flash.
Place a suitable pan on the hotplate to stop the indicator flashing. If there
is a delay of more than 90 seconds, the hotplate switches off automatically.
Empty pans or pans with a thin base
Do not heat empty pans and do not use pans with thin bases. Although
your hob is equipped with an internal safety system, empty cookware can
heat up so quickly that the “automatic OFF” function does not have time to
react and a very high temperature may be reached. The base of the pan could
melt and damage the hob’s glass surface. If this happens, do not touch the
pan and switch off the hotplate. If it does not work after cooling, contact our
Local Service Center or dealer.
Pan detection
Each hotplate has a minimum limit for pan detection which varies
according to the material from which the pan being used is made. It is for this
reason you are recommended to use a hotplate which matches the diameter of
the pan.

9. Residual heat indication
When switch off the heating elements, the temperature on the glass
surface is high, it may harm the human body or cause a fire. And the Touch
Control has the residual heat indicating function, the “H” will be indicated
on the 7-segment to inform the end users the temperature is still high and do
not touch the surface of the cooking zone until the warning of “H”
disappeared.
For radiant heating elements, the determination of how long a cooking
zone has residual heat after operation and switch off – which may lead to
burnings when contacting – is calculated.
Status is calculated depending on:
- Selected power stage („0“ bis „9“).
- On/Off Time of the Relais.
For induction heating element, the residual is determined by Induction
heating element temperature sensor. When the temperature is higher than +
65 °C, residual heat indication will be occurred.
