WHAT DOES COOKING WITH INDUCTION MEAN?
Cooking with induction is based on a completely different principle than the usual ways of heating. The heat is created directly in the cooking utensil, whilst the hotzone remains cold. This method of heating has many advantages in comparison with other ones:

1. Saving of time at cooking and baking
   The cooking utensil is heated directly, not the glass-ceramic plate. There are no big heat losses so the effectiveness is higher than other heating methods.

2. Energy saving It is established that cooking with induction consumes less electric power than other cooking methods.

3. Controlled supply of heat and more safety
   The heating plate transfers heat or interrupts its supply immediately after setting the power. As soon as you take the cooking utensil off the heating plate, heating is interrupted without the need to switch off the hotzone. After the end of cooking, only residual heat coming from the cooking utensil remains on the heating plate. Nevertheless, we do not recommend leaving anything on the plate without attendance. Note: So as to prevent unwanted heating, e.g. in the case of laying metal instruments on the plate, the system activates only if the bottom of the utensil is of a specific dimension or bigger.

WARNING! This unit complies with the directive of safety and electromagnetic compatibility; nevertheless, people with a pacemaker should not approach the unit. Some other devices, such as hearing aids, etc., could malfunction too.
If the unit is on, do not bring magnetically sensitive things (diskettes, credit cards, magnetic tapes, etc.) near it.

OPERATING INSTRUCTIONS

• Areas designed only for cooking electrical hotzones are indicated on the heating plate. The diameters of the hotzones are derived from the usual dimensions of cooking utensils.
• Only the surface inside the indicated diameter is heated; other surfaces remain relatively cold and can be used as lay aside areas.
• The temperature limiter prevents hotzones under the glass-ceramic plate from overheating.
• The shining “H” symbols on the indicator position of the input levels signal the increased temperature of the hotzone after switching off. The hot area can be energetically utilized. The symbol will go off as soon as the hotzone has cooled down to such a temperature that there is no longer any risk of burning.
• The inputs of hotzones are controlled within the range of 9 levels, which can be selected by pressing the touch symbols with respective indicators on the control panel. At each pressing of a symbol, a beep can be heard. The response time for pressing a symbol is 1 second, for which period it is necessary to hold your finger on the symbol.

COOKING TIPS

Some examples of the setting of input levels:
a) Level 1-3 is designed for

• keeping liquids simmering,
• moderate and slow heating without the risk of burning,
• melting of butter or chocolate,
• defrosting,
• boiling a small quantity of liquid.

b) Levels 4-6 can be used for

• intensive boiling,
• keeping a larger quantity of liquid boiling,
• stewing.

c) Level 7-9 can be used for

• cooking food requiring fast heating and high temperature (beef steaks, schnitzels, friend potatoes, etc.)
• heating food before switching over to a lower level.

ENERGY  SAVING TIPS

• The flat bottom of the utensil
  Use pots and pans with thick flat bottoms. Uneven bottoms result in an extension of the cooking time.

• The proper size of utensils
  Use the proper size of the cooking utensil for each hotzone. The diameter of the bottom of a pot or pan should be smaller than or the same as the hotzone size.
  Note: Take into account that manufacturers often state the upper diameter of a cooking utensil, which is usually larger than its bottom diameter.

• adequate size of utensil
  For a small quantity of food use a little pot. A large and only partially filled pot needs too much energy.

• Covering by a lid
  Always cover pots and pans with suitable lids. Cooking without a lid implies the consumption of much more energy.

• Cooking with a little quantity of water
  Cook food with a little quantity of water. Thus you save energy. Vitamins and mineral matters will remain preserved when cooking vegetables.

• Switching over to a lower power level
  Switch over to a lower power level on time.

CLEANING AND MAINTENANCE

The heating plate itself does not warm up, so no remains of food can get burnt on it. For cleaning the heating plate, you do not have to wait until it cools down.
Never use high-pressure cleaners or autoclaves for cleaning the heating plate.
Maintenance
For the care of the heating, plates uses a protective and preservation agent designed for glass-ceramic surfaces.
It will cover the heating plate with a protective layer that repels dirt and facilitates cleaning.
Cleaning of the heating plate
Clean the heating plate after each cooking session. It will prevent the remains of food from burning during the next cooking session.
For the removal of food remains and the layer of grease use a glass scraper.
For cleaning the lukewarm heating plate use a cleaning agent and a paper towel. If the plate is cleaned while hot, stains could appear on it.
Then wipe the plate with a damp cloth and wipe it dry using a soft cloth.
Cleaners
Use cleaners suitable for glass-ceramic surfaces, e.g. CERA, CLEN, Cera-fix, Sidol for ceran + steel.
Water stains can also be removed by means of lemon or vinegar.
Improper cleaners
Never use Coarse sponges, abrasive agents, or aggressive cleaners such as the spray for cleaning ovens and stain remover.
Scraper for glass
Tough dirt should be removed preferably by means of a glass scraper.
Release the scraper.
Clean the heating plate with the edge only.
The holder of the scraper could scratch it.
WARNING!
The scraper is very sharp. The danger of injury! After cleaning, secure the scraper again. If the edge is damaged, release it immediately.
Metallic-gloss coloring
Metallic-gloss coloring appears after the use of unsuitable cleaners or abrasion of a cooking utensil bottom. Its removal is very difficult. Use Stahl-Fix or Sidol for ceran+steel. Removal of this coloring in our service centers is charged for.
Control panel
Keep the panel clean and dry. Food residue and food that has boiled over may affect the performance of the controls.

After fixation of the ends of the wires under the heads of the screws in the terminal, box inserts the cable in the terminal box and secure it with a clip against pulling out.
After the connection turn the unit into the working position, put it in, cut it out, and check the position of the supply cable.

TROUBLESHOOTING

The household wiring protection reacts to the switching on of the heating plate.| Check that the input of all switched-on units does not exceed the maximum load of the household wiring. Check whether the protection breaks in case of switching on of another hotzone too.
The heating plate has been switched off.| Somebody has touched the main switch accidentally. Switch on the heating plate again. Perform setting once more.
When you put a utensil on the induction hotzone, the „U” symbol is displayed (and the hotzone does not heat).| Check whether the cooking utensil is electromagnetic (i.e. whether it attracts a magnet). Check whether the bottom diameter of the utensil is sufficient.
If the cooking utensil has got too hot during use, let it cool down. If the indicator does not shine even after the next switching off and on again, disconnect the heating plate from the mains. Wait 20 seconds and then connect it again.
Displayed code FO, Fl, F2| Cooling fan defect. Contact an authorized service center.
Displayed code F3-F8| Temperature sensor defect. Contact an authorized service center.
Displayed code El, E2,| Incorrect voltage. Check the supply voltage.
Displayed codes E3, E4,| Too high temperature. Check the type of used utensil.
Displayed codes E5, E6,| Overheated hotzone. Let it cool down before the next use.

Operation sounds of the unit
The induction heating technology is based on specific parameters of metal materials, when under the influence of high-frequency waves. Under special circumstances, these vibrations can manifest themselves by weak sounds, which do not signal any fault. These include:

Deep hum such as at a transformer| This sound accompanies cooking at a high power level. It is caused by big amount of energy that is transferred from the heating plate to the cooking utensil. This sound will disappear or weaken as soon as the hotzone is switched over to lower power.
---|---
Beeping| This sound usually appears in the case of an empty cooking utensil. It will disappear when you pour water or put food in the utensil.
High beeping sounds| These sounds appear mainly with cooking utensils consisting of several layers of various materials when they are in operation at the maximum heating power. This effect does not influence the result of cooking. The beeping disappears or weakens as soon as the power is reduced.
Crackling| This sound appears with cooking utensils consisting of several layers of various materials. It is caused by vibrations in the connecting areas of individual layers. The sound depends on the cooking utensil. It may change in dependence on the quantity and kind of food being cooked in the utensil.
Sound of the fan| For the good operation of the electronics, it is necessary that it works at a permanently controlled temperature.  the hat is why the heating plate is equipped with a fan that can be set to various power levels according to the measured temperature. The fan may work even after the switch- off of the heating plate,  f the measured temperature is still too high.
