Before Installation

If you are receiving the unit from a transportation company, it is customer’s obligation to inspect thepackage and note any damage on the delivery receipt. After delivery, have your induction cooktop carefully unpacked, and again check forany visible damage. If you find any damage onthe unit at this point, immediately inform your dealer or distributor. Although the responsibility for shipping lies with the carrier, your dealer/ distributor will assist you with your claim.

If the unit is not supposed to be installed for some time, you should keep it in its original packaging, stored in a dry and safe place.

Read through the section of this manual which pertains to installation, and make sure that all of the requirements can be provided or are already provided. Ensure that your electric power supply is correct.

Before you install the unit, you should take a moment to write down the information from your nameplate and fill-out the table on page 19, for future after-sale servicing needs. This information will be required every time you call for any service on your unit.


99637761_A_EN.qxp 19/07/2005 11:49 Page 6


To install the cooktop, cut out a rectangular opening in the counter as shown on the drawing and table below. Also, ensure that you have a minimum of 10 mm (3/8”) of space in the back of the unit, between the rim and backsplash on your counter (or wall if no backsplash) for ventilation.

A self-adhesive gasket is supplied with your unit. Before setting the cooktop in place install this gasket by sticking it underneath the rim.

IApply the gasket only along the front rim and on both sides. Do not put this gasket on the rim in the back. This gasket will prevent most of the spills from entering the cabinet below and will keep the unit in place. Once the gasket is installed, place the cooktop in the opening, and lay it on the rim. Do this carefully - do not drop the unit into the cutout. Make sure that the unit is sitting properly on its rim all around the perimeter.

f your counter is produced from porous materials which tend to swell if in contact

with humidity and water, to better protect the cut-out, use proper sealants on the

edge which would prevent any penetration of humidity and water. Chamfer all exposed edges of decorative laminates to prevent further chipping. Radius corners of the cut-out and file them to ensure smooth edges and prevent

corner cracking.

Rough edges and inside corners which are not rounded as well as forced fits can contribute to cracking of counter top laminate.

A minimum vertical clearance of 750 mm [30”] is required between the top of the cooking surface and the bottom of any unprotected combustible material, such as cabinets, wooden trim etc.

In the back, leave a minimum of 10 mm [3/8”] between the cooktop edge and adjacent vertical surfaces (backsplash, wall, high cabinets etc.). This space is needed for the unit to breath properly.

If a downdraft ventilation system is used, a minimum of 6 mm (1/4”) of clearance is required between the rear edge of the cooktop and the downdraft snorkel.

Leave a minimum of 50 mm [2”] underneath the unit for the air intake.

During cooking, built-in fan inside the cooktop will operate constantly to keep the internal components cool. The air intake is on the bottom of the cooktop box, and the warm air exhaust is located on the back of the rim, as shown on the schematic. If the air intake or the exhaust is obstructed, the cooktop safeties will either diminish the power output or shut down the unit.

We suggest that you should periodically check that there are no objects (dust, paper,

etc.) which could obstruct the air inlet under your induction cooktop.

Although induction-cooktop heat rejection is minimal and the unit does not create any fumes in operation, such unit must be installed underneath a properly sized ventilation hood for exhausting any smell, vapor and smoke created by cooking itself.

Also, a proper downdraft system can be used for ventilation.

Your cook-top must always breath adequately. Make sure that the air inlet and its exhaust are not obstructed.

The unit must not be installed above a washing machine, a refrigerator or a deepfreezer box

To eliminate the risk of burns or fire by reaching over heated surface units, cabinet storage space located above the surface units should be avoided.

The unit must be installed such that it can be pulled without difficulty out of the cut-out for servicing or cleaning.

Never glue, silicone or wedge the unit inside its cut-out.

Safety Precautions - Read before operating your cooktop

Your induction-cooking unit has been designed for residential use and food preparation, and all of the safety parameters have been rectified accordingly.

The unit incorporates numerous safety devices and controls, and a few devices will be mentioned here.

-A number of sensors monitor temperature of internal components. If any of these sensors senses that the component temperature is above the limit, the power output of the unit will automatically be reduced, allowing the component to cool down. Once this is achieved, the unit will continue to operate normally at the output level set initially by the operator.

-Each induction coil is equipped with a sensor which is continuously monitoring the temperature of the bottom of the pan to prevent the pan from overheating.

-Each induction coil is equipped with a pan sensing device. This device will not allow the heating element to turn on unless it senses a cooking utensil on the coil covering enough surface area. The indication that the coil is not running is the flashing of the digital display. Once the pan is put properly on the coil, the digital display will become steady. Note that a small object such as a fork, a spoon, a piece of jewelry, etc. will not be mistaken for a cooking utensil, and it will not trigger this sensor. Moreover, this device will distinguish between cooking utensils which are and are not suitable for induction cooking. If a cooking utensil which is not suitable for induction cooking is placed on a coil there will be no power output on the coil.

-If an operator leans on the keypad by chance for more then ten seconds, controls

will disable the heating section of the unit. This occurrence is called ‘long press’ and when it happens “-” signs will appear on power displays. The unit will act the same if there is an accumulation of some liquid on the keypad area, or if a damp cloth is left sitting on the keypad. The section will become operational again once the spill or the object/hand is removed, and the element turned back on.

In an effort of constantly improving our products, we reserve the right to make any changes to internal components, as well as, to make any(cosmetic) modifications on the outside frame.

This unit does not contain any asbestos or asbestos based components.

This unit has been tested and certified under FCC CFR 47, Part 18, for electromagnetic interference.

The users with heart pacemakers must consult with the pacemaker manufacturer prior to using this cooktop which incorporates induction heating source.

If a crack appears in the glass surface, disconnect the unit immediately to avoid any risk of electric shock. If the unit is connected directly to supply inside a junction box, then

disconnect its breaker, or remove fuses manually.

Do not re-use your cooktop until the glass top is changed.

When cooking never use aluminum foil and never place products wrapped in aluminum foil, nor products deep-frozen in aluminum packs on the hob. Aluminum foil could melt and damage vitroceramic glass surface beyond repair.

The principle of induction

When an induction element - also called: ‘a heating zone’, or simply: ‘a coil’ - is switched on, the appropriate utensil is used, and a desired level of heating power selected, the electronic circuit unit (‘induction generator’ or ‘inverter’) powers up the induction coil which creates a magnetic field. This magnetic field continuously changes in terms of frequency and intensity, and this creates induced currents in the bottom of the utensil and ultimately results in heat. The heat is transferred directly to the food being cooked.

Thus, induction heat makes the utensil a direct source of heat, featuring high level of efficiency with extremely low energy loss and unparalleled heating level control.

With induction cooking there is very little ‘heating inertia’. Induction cooking elements do not incorporate a heat generating element - unlike convectional electric rings, halogen or radiant elements etc. - therefore, heat levels can be changed very quickly.

Energy efficiency for induction is within range of 90-95%, compared with 55-65% for conventional and radiant element, or 45% - 55% for gas fueled burners. The energy efficiency contributes to substantial energy savings, both beneficial to the owner as well as the environment.

Induction cooking elements are sensitive to the utensil type being used :

-if there is no utensil placed on the coil, or if the utensil is not of induction grade, there will be no power emitted by the coil;

-if the utensil is placed partially on the coil, or if it is smaller than the coil, the internal sensors will reduce power to the coil; The Principle of Induction


















Induced currents





- if the utensil is fully removed from the coil, the power output will be instantaneously reduced to ‘0’, and, eventually, the controls will turn the element off after a minute, unless the utensil is returned back onto the coil.

When compared to the other methods of cooking, induction cooking has a very low level of ambient heat, thus makes cooking more pleasurable, with a reduced need for ventilation.

Finally, the vitroceramic glass as a cooking surface barely becomes hot and this makes cleaning much easier.

For a proper choice of utensils, please refer to “Utensils for Your Induction”

When using induction elements, some utensils may produce faint humming sound. This is a normal occurrence - the noise is a result of vibrations caused by induced currents.

To check the suitability of your cookware:

Place the vessel on a cooking zone at power level 4.

If the display remains on, your cookware is compatible.

If the display flashes, your cookware cannot be used with induction cooking.

You can also use a magnet to test the cookware.

If a magnet "sticks" to the bottom of the cookware, it is compatible with induction.


Under the pretense that only one zone is used with an adequate utensil covering the whole surface of the coil, and that power on the zone is adjusted to the maximum (‘12’):

-the maximum power output of 22 cm (9”) heating zone is 2.8 kW;

-the maximum power output of 16 cm (6 1/2”) heating zone is 2.2 kW.

If only one coil is employed, it can be utilized at its maximum power, but as soon as the other coil is turned on, the controls adjust the power on both coils automatically for ‘power sharing’. This power sharing is administered by unit’s microprocessors, which will alternate power between the two elements. There are two factors affecting improved power sharing on your cooktops.

The first is the application of an improved technology for power sharing - not using common relays, but rather semiconductors which makes power sharing quicker, thus more efficient. The second factor is that, when in a power-sharing mode, two zones can share full, 3.6 kW, power output of the inverter.

Note that the controls will not allow both zones to operate at full power, and the power will be adjusted automatically - e.g. if the power on one zone is adjusted to a maximum, and the other zone is turned on and power level also adjusted to its maximum, the power level on the first zone will automatically become lower. This change will be visible on digital displays. The controls are set in such a manner that the last instruction (command) given to an element is always a priority.


99637761_A_EN.qxp 19/07/2005 11:49 Page 13

Utensils for Your Induction

Induced current can be created only in materials which have magnetic properties. Thus, utensils for use with an induction unit must be made from a ferromagnetic material or have inserts with magnetic properties. Your household may already have cookware suitable for induction cooking, and you may test any utensil with an induction element. Incorporated controls are able to recognize a suitable utensil. To perform a utensil test:

-Turn an element on and adjust power to any level - you will notice that the digital power display is flashing.

-Place your utensil on the coil. If the piece being tested is suitable for induction cooking, the display will become steady. However, if it keeps flashing, the utensil cannot be used on your induction unit.

-If the utensil is empty, remove it from the coil immediately after you have done test and turn the element OFF.

Another simple test to determine if a piece of cookware can be used on an induction cooktop is the ‘magnet test’. Use a magnet and place it on the utensil. If the magnet sticks to it, the piece will work with induction.

Utensils compatible with induction are:

Cookware made of enamel coated steel with or without a non-stick coating.

Cast iron cookware with or without enamel coated base.

Stainless steel pots and pans designed for induction cookware.


Stainless steel used for utensils is nonmagnetic, in most cases, and unsuitable for

induction cooking, but most manufacturers make such utensils in layers for better heat distribution, and a good number of such pots and pans can be used with induction. To make sure if a stainless steel utensil can be used perform the utensil test.

Use of utensils with enameled coated base will prevent the glass top of your unit from getting scratched.

Pots and pans which do not have a flat bottom still may be used, however they should not be overly deformed.

Cookware made from glass, ceramic, earthenware, aluminum and copper pots and pans and non-magnetic stainless steel cookware are not suitable for induction cooking.

Matching Pots & Pans with Coils, etc. Small elements,16 cm (6 1/2”), are best utilized:

-With small utensils - but normally not smaller then 10 cm (4”);

-For slow cooking and simmering (sauces, creams, etc.);

-For cooking small quantities of food. Large elements, 22 cm (9”), are primarily designed for day-to-day cooking needs and most commonly used pans - 18 to 25 cm (7 to 9 1/2”) in diameter.

When cooking large quantities of food, it is always better to use a large diameter pan and a larger coil, thus better and more efficient heat distribution will be achieved and food cooked evenly.

Utensils with thick flat bases should be chosen for the benefit of uniform heat distribution.

Never leave an empty piece of cookware on an induction heating element for more then a few seconds. If a utensil is left on an element at full power, temperature of the dish may

increase rapidly, the safeties would not engage, and this may damage your utensil, the cooktop, and could result in an injury or a damage to your property.


99637761_A_EN.qxp 19/07/2005 11:49 Page 14

To Do or Not To Do

You must:

-Always place your utensil such that its center is aligned with the centre of the coil.

-Avoid hitting the vitroceramic glass with utensils or any hard objects - the glass surface is highly resistant but not unbreakable.

-Pick-up your utensils when moving them around. Do not slide them and avoid excessive rubbing of the top, as this leaves scratches and erases the markings .

-Avoid using utensils with rough or deformed bottoms.

-Avoid leaving any metal cooking accessories, knives and forks, or metal objects on the hob. They may get hot if left close to any heating element in use.

-Avoid storing flammable products in the cabinets under your cooktop.

-Never leave an empty utensil on an induction heating element, even when the element is turned OFF.

-Only use maximum power for boiling and frying.

-Never try heating up a closed can.

-Avoid pre-heating your non-stick pans (e.g. with teflon coating) at maximum heat.

-Avoid storing solid and heavy items in the cabinets above your cooktop. They may unintentionally drop and damage the glass. To Do or Not To Do

Do not connect any appliances to the plugs above or near to the induction cooktop; connection cable insulation can melt if in contact with heat, and this may result in an injury and a property damage.

Your cooktop must never be used as a storage space or surface for piling up of any material.
