HOW DOES YOUR INDUCTION WORK?
A high frequency (20-35KHz) induction coil underneath the ceramic top plate heats the cooking utensil by
magnetic friction. The heat is produced directly within the pan and is controlled by an electronic circuit which
offers superior performance and functions.
During cooking, no energy is lost between the hob and the food. When the unit is switched off, or the pan is
removed, cooking and heating stops immediately.
PRECAUTION BEFORE USING YOUR INDUCTION HOB
1. The ceramic top is of strong & non-porous properties. In case of breakage, even if it's only slightly
cracked, disconnect the unit from the main power supply and contact the after sales service dealer.
2. The unit is equipped with a 'SMALL OBJECT DETECTOR' It's recommended not to place metal kitchen
utensils, pan lids, knives, or other such objects on the heating zone. If the unit is turned on, there is a risk
that the utensils may become hot.
3. DO NOT place credit cards, cassettes or other magnetic sensitive objects on the ceramic top.
4. Scientific tests have shown that the induction presents no danger whatsoever for persons using a
pacemaker. It is recommended that a distance of 60cm be maintained whilst using the induction unit.
5. To prevent from over heating, DO NOT place aluminum-foil on the ceramic top.
6. Put the unit on a flat and even surface, but allow a space from the wall or other objects of at least 5-10cm to
allow for proper ventilation.
7. Immediate clean-up is recommended when any spillage occurs.

USE AND CARE INSTRUCTIONS – IMPORTANT SAFEGUARDS
1. DO NOT block the air-intake panel, as this may overheat the unit.
2. We recommend pans to be in the range of 12~26cm in diameter. Please refer to the next page for a list
of suitable and unsuitable pans.
3. DO NOT touch the hot surface of the ceramic plate. NOTE: The induction unit itself does not produce
any live heat during cooking, however, the heat reflected from the pan will leave the surface of the
ceramic hot!
4. DO NOT cook with empty pots or pans. Heating an empty pan will automatically activate the
overheating protection device and the unit will shut off.
5. Place the induction unit on a flat & even surface and at least 10cm away from the wall and other objects
for proper ventilation
.
6. DO NOT place any objects or tools in the air-intake panel. Doing so may cause electrical shock.
7. To protect against electrical shock, DO NOT immerse the unit, the cord or the plug in or near water or
other liquids.
8. Close supervision is necessary when the induction unit is used or near children.
9. DO NOT operate the induction unit if it has been damaged in any manner or if the unit malfunctions.
Return the unit to the nearest authorized service facility for examination or repair.
10. The use of any accessories or parts not recommended by the manufacturer may cause injuries.
11. Keep the power cord away from heat.
12. DO NOT place the induction unit in, on, or near open flames, electric burners, heated ovens or other
high temperature surroundings.
13. DO NOT heat any sealed cans on the induction unit. Aheated can may explode.
14. DO NOT move the induction unit while cooking or when the pan is hot.
15. After the induction unit has cooled down, unplug the cord and clean as follows,
CERAMIC PLATE: wipe with damp cloth or use a mild, non-abrasive cleaning solution.
BODY: wipe the control panel with soft cloth or use a mild cleaner.
16. DO NOT use induction unit for other than intended use.
17. Unplug when not in use.
18. When storing, DO NOT place any objects on top of the induction unit.

SAFETY DEVICES
Safety Device
To comply with CE safety regulations there are two steps to turn on the induction unit.
First step: Push power ON/OFF key.
Second step: Within 5 seconds, turn power regulating knob OR push temperature select key "+", "-".
Automatic Safety Shut-Off,
If the induction unit is left on for more than 60 seconds without a pan or with an incompatible pan, the unit will
automatically shut off.
Material Compatibility Detector
If the pan’s material or it’s dimensions are not suitable for the induction unit, the power indicator light will not
light.
Small Object Detector
The induction unit will not recognize any objects or utensils smaller than 5cm in diameter. For best results,
use pans that are between 12cm and 26cm in diameter.
Overheating Protection Device,
If the temperature of the pan reaches 250oC, and the temperature remains for 60 seconds, the unit will shut
off automatically, there will be a short warning sound.
IC Automatic Reset Device
Main control micro processor equipped with watch "Dog Device", the IC will automatically reset when the
software programme malfunctions.

OPERATING INSTRUCTIONS
1. Ensure that the electrical supply matches with the electrical specifications on the data plate located on
the under side of the unit.
2. Place suitable pan on the center of the ceramic top.
3. Press power ON/OFF key, heating lamp will light and LED power level will be displayed.
4. If the heating indicator light is on, then the pan is heating.
5. Select mode "HEAT" or 'WARM" by pressing the required key, the indicating lamp will light.
HEAT
Press heat function key, heat indicator lamp will light.
Set heating level by rotating the power control knob 1~19. LED display will show the level
settings.
WARM
Press WARM function key, heat indicator lamp will light.
Set required temperature by pushing "up arrow" & "down arrow key. The selection is from
50oC to 240oC, each additional 10oC per step.
The warm indication light will flash until the required temperature is reached.
When using the 'WARM' mode the rotating power control knob will not function.
To change from 'WARM' to 'HEAT' press the heat function key and the power control knob will
be activated.
NOTE
When the unit has been turned 'ON' the heating indicating light will be on. This indicates that the
pan is heating.
If the indicating light is OFF and there is a beeping noise this indicates that
- the pan is not suitable
- there is no pan on the ceramic top
The unit is equipped with an "OVERHEATING PROTECTION DEVICE". When the temperature
of cookware base is too hot, the power will cut out. The heating indication light will flash indicating
that the over heating function is on.
Once the temperature reduces, the power will automatically re-start.
CAUSE OF OVERHEATING
If an empty pan is placed on the ceramic top and the power level is at maximum the ceramic
surface will reach a high temperature very quickly. Once the pan is removed from the unit or food/
liquid is added to the pan, the surface temperature of the ceramic top will reduce very rapidly.
