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.

ex: No.1 Place a damp cloth on the control panel.
No.2 Liquid boils over and lands on the control panel.
No.3 More than one key is pressed for more than
8 seconds.
No.4 Defective Assy-Touch PCB
It occurs when the Touch key data at Display PCB is interrupted, due to some noise, defects of Display PCB.
It occurs when the temperature of the Top Sensor rises
very highly.
(Estimated temperature of ceramic glass’s surface is
more than 250˚C.)
ex: Place a empty cookware on the burner and operate the
hob.
It occurs when the cookware is unsuitable or too small or
no cookware has been placed on the cooking zone.
If the suitable cookware is placed again, the hob will operate normally.
It occurs when the DC Motor cannot operate due to defects
of PCB, wiring or some disturbance on motor blade.

(220V~240V, 50/60Hz)
YES
YES
YES
NO
No Power
Check the wiring.
NO
Check the votage of PCB, SMPS
-input : 220V~240V
-output : 12V, 5V
Replace the defected PCB.
Check the terminal block connections
Check the circuit breaker.
Replace or Repair the wiring
Troubleshooting (Heating)
Check the relay terminal voltage
(220V~240V)
NO
YES
YES
