1Safety
1.1 Description of danger signs
This symbol identifies the safety information
which may cause danger (personal injury) for
people at non-observance of proper operation.
This dangerous voltage warning symbol
indicates a risk of electric shock and hazards
from dangerous voltage.
CAUTION
Indicates a hazard or unsafe practice which
could result in minor personal injury or
property damage.
Electromagnetic field
Information signs mounted directly on the cooker must be observed at all times and kept in a
fully legible condition.
1.2 Qualification and training of personnel
The staff for assembly, installation, commissioning, operation and maintenance must have the
appropriate qualification. The field of responsibility, competence and supervision of the staff
must be defined and controlled.
1.3 Safety prescriptions for installation and service
The operating personnel has to make sure that installation and service as well as all inspection
is done by authorized and qualified personnel. This personnel must have read very carefully
the „Instructions for use“ in order to meet the requirements. For installation, service,
maintenance, repair and overhaul of the induction cookers, the personnel has to be specially
qualified and must have attended a special training, authorized by the manufacturer.
In principle, such work at induction appliances must only be carried out when it is under no
electrical tension. The cookers must be switched off and disconnected from the electric

connection. The installation of safety and protection must be re-installed after finishing the
work.
1.4 Unauthorized reconstruction and use of spare parts
Reconstruction of the cooker or changes to the cooker are not allowed. Contact the
manufacturer if you intend to do any changes to the cooker. To guarantee safety, use genuine
spare parts and accessories authorized by the manufacturer. The use of other components will
cancel any liability for the resulting consequences.
1.5 Improper operating methods
The operating reliability of the cookers can only be guaranteed with appropriate use of the
cooker. The limit values may be exceeded on no account.

3Functioning
3.1 Adjusting the performance rate
The performance rate is adjusted by the potentiometer (control knob). The inductive
performance depends on the position of the potentiometer:
•Position 1 = minimum power
•Position 9 (resp. Position 12) = maximum power.
3.2 Check of the temperature
Induction coil
The temperature of the induction coil is checked by a temperature sensor. If the coil is heated
over the maximum temperature, the heating process is stopped. As soon as the coil has cooled
down, the Induction unit can be re-started. Turn the position of the kontrol knob on „0“ and
then on the required power level (see chapter 7.2 Error Messages).
Power board
The temperature of the heat sink is checked by a temperature sensor. As soon as the heat sink
is heated over 60ºC/140ºF, a cooling fan is started. A temperature of the heat sink of more
than 75ºC/167ºF will reduce automatically the power in order to keep the induction cooker
working under normal conditions. The internal temperature of the unit is supervised as well.
The power will be reduced when the temperature reaches 70°C/158°F. As soon as the
temperature reaches 80ºC/176°F the unit will stop working and show the error code E06 (see
chapter 7.2).
3.3 Overload current protection
When inappropriate pan material or magnetic objects are detected on the heating area, the
current in the induction coil may rise substantially. In order to protect the power board, the
coil current is checked. As soon as the current in the coil exceeds the tolerance, the generator
will cut out and there is no further active energy exchange. The unit can be re-started as soon
as normal working conditions are reached.

4Tests
4.1 Pan material for induction cookers
When cooking with induction it is most important to use appropriate pan material. The bottom
of the pan is the element that closes the magnetic field generated by the induction coil. We
recommend to use only appropriate pan material.
In order to check your pan, make a test. You will need 1lt water of about 20ºC/68ºF. Heat up
the pan with maximum power and measure the time it takes until the water is boiling. Refer
and compare to the reference time given by INDUCS Ltd. (2,5kW approx. 240 sec., 3,5kW
approx. 140 sec., 5kW approx. 80 sec., 8kW approx. 60 sec.). This heating-up time
gives you information about the efficiency of the pan. Bad pans have considerably longer
heating-up times for the same quantity of water.
In order to find out whether the pan material is appropriate for induction, use a magnet. This
has to stick to the bottom of the pan. This test says nothing about the efficiency or the
material structure of the pan (it can be a bad induction pan).
4.2 Pan detection
ATTENTION
The heating area is warmed up by the hot pan.
To avoid injuries (burnings) do not touch the
heating area.
This test shows whether the induction cooker is working well when pans with a small
diameter are used and if small metallic objects are heated-up on the heating area.
To do this test, you need the following material:
An appropriate pan with a bottom diameter of 12cm/4.7“ or two untreated round iron plates,
approximately 4mm/0.16“ thick:
•iron plate 1: diameter d = 12 cm/4.7“
•iron plate 2: diameter d = 7 cm/2.75“

4.7 Fan
With this test, fan, fan controller as well as the degree of soiling are verified. At the beginning
of the test, the induction cooker should be cold. You need a pan with a bottom diameter of
>28 cm/11“.
Step Action Level Result
1 Put a pan on the heating area and fill a
few litres of water in it
9 (12) Heat
2 Measure the time until the fan starts
working
9 (12) The fan should start working
in 6-8 minutes
3 Go on cooking for about 30 minutes 9 (12)
4 Turn off the induction cooker 0 The fan keeps working.
4.8 Test of the components
CAUTION The mains cable must be switched off.
4.8.1 Rectifier
The rectifier is fixed at the power board with four wires. These rectifier connections have to
be unsoldered for correct test results At first, you have to measure the forward voltage
between anode – cathode by means of the multimeter (please use only multimeters with diode
check as an additional function).
The forward voltage for this diode is about 0,5V in the direction A – C, in the opposite
direction there is no current flow.
