1. General Safety Precautions
1. Information contained in this manual is intended for
use by a qualied service technician. The technician
is required to be familiar with proper and safe procedures to be followed when repairing appliance.
All tests and repairs are to be performed using
proper tools and measuring devices. All component
replacements should be made using only factory
approved replacement parts.
2. Electrical shock and injury can result if service or
repairs are attempted by an unqualied individual.
Improper disassembly, assembly or adjustments
can create hazardous conditions.
3. Even for a skilled technician, a risk of injury or
electrical shock exists while performing service or
repairs. Electrical injury can be serious or fatal.
Extreme caution must taken when performing
voltage checks on individual components of an
appliance.
NOTE
Except as necessary to perform a particular
step in servicing a product, the electrical power
supply should always be disconnected when
servicing a product.
4. To avoid possible injury, the appliance must be
properly grounded. Never plug in or direct wire an
appliance unless it is properly grounded. See the
installation instructions that originally accompanied the product for proper grounding procedures.
5.The ventilation gap between the worktop and front of
the unit underneath it must not be covered.
8. The hob is to be connected to the mains using a
device that allows the appliance to be disconnected
from the mains at all poles with a contact opening
width of at least 3 mm, eg. automatic line protecting
cut - out, earth leakage trips or fuse.
9. Pay attention (conformity) to phase and neutral
allocation of house connection and appliance
(connection schemes); otherwise, components can
be damaged.
Warranty does not cover damage resulting from
improper installation.
If the supply cord is damaged, it must be replaced
by a special cord or assembly available from the
manufacturer or its service agent.

6. Before connecting, check that the nominal voltage
of the appliance, that is, the voltage stated on the
rating plate, corresponds to the available supply
voltage. The rating plate is located on the lower
casing of the hob.
7. The heating element voltage is AC230V~. The
appliance also works perfectly on networks with
AC220V~ or AC240V~.

2. Specications
2-1 Induction Heating
• The Principle of Induction Heating: When you place your cookware on a cooking zone and you turn it on, the electronic
circuits in your induction hob produce “induced currents” in the bottom of the cookware which instantly raise cookware’s
temperature.

NOTE
Pay special attention to the minimum space and clearance requirements.
NOTE
The bottom of the hob is equipped with a fan. If there is a drawer under the hob
it should not be used to store small objects or paper, since they could damage the
fan or interfere with the cooling if they are sucked into it.
NOTE
Make a note of the serial number on the
appliance rating label prior to installation.
This number will be required in the case
of requests for service and is no longer
accessible after installation, as it is on the
original rating plate on the underside of the
