The residual heat Indicator tells you if the hotplates are hot (See Residual heat warning light section ). It may cause a fire! Never rest flammable objects on the cooking hob. It may cause a fire! If there is a drawer below the induction hob, this should not be used to store any flammable objects or sprays. Wet hotplates and pan bases Risk of injuries! If there is any liquid between the base of the pan and the hotplate this could generate steam pressure. As a result, the pan could jump unexpectedly. Always ensure that the hotplate and the base of the pan are kept dry. Cracks in the hob Risk of electrocution! Disconnect the appliance from the mains if the induction hob is broken or cracked. Contact Local Customer Service or Dealer. 4

5 The hotplate heats up but the visual indication does not work Risk of burns! Disconnect the hotplate if the indicator does not work. Contact Local Customer Service or dealer. Do not place metal objects on the Induction hob Risk of burns! Do not leave cutlery, lids or other metal objects on the hob as they can heat up very quickly. Taking care of the cooling fan This induction hob is fitted with a fan in the lower section. Risk of malfunction! If a drawer is fitted beneath the hob you must not keep small objects or paper in it as, if they are Picked up, they could damage the cooling fan or affect the cooling system. Please, note: there should be a minimum distance of 2 cm between the drawer contents and the cooling fan. Incorrect repairs Risk of electric shock! Incorrect repairs can be dangerous. Repairs may only be carried out by the Customer Service. Power cable Any work on the appliance, including replacing the power Cable must be carried out by the Customer Service. The power cable of the appliance must not touch the hot areas of the hob. The cable insulation and hob can be damaged. This appliance complies with current safety regulations and electromagnetic compatibility regulations. Nevertheless, people with a peacemaker should not use this appliance. It is impossible to guarantee that all such devices found on the market comply with current safety regulations and electromagnetic compatibility regulations, and that dangerous interference will not occur. It is also possible that people with other types of device, such as hearing aid, could experience some discomfort. Switching the hob off Always switch the hob using the main switch of the Control Panel after each use. Do not wait until the hob switches off automatically when the pan is removed. 5

6 Causes of damage: The base of the pans The rough bases of pans may scratch the hob. Avoid leaving empty pans on the hotplates. These may cause damage. Hot pans Never rest hot pans on the control panel, the indicator area or the hob surround. Salt, sugar and sand salt, sugar and sand may scratch the ceran glass. Do not lean on the hob or use it as work surface. Hard and pointed objects Hard or pointed objects may cause damage if they fall onto the hob. Spilt food Sugar and other similar products may damage the hob. These products should be removed immediately using a glass scraper. Inappropriate cleaning products Discolorations in the metal are caused by using unsuitable cleaning products and wear as a result of contact with pans. Plastic and foil Aluminum foil and plastic containers will melt if placed on the hot areas of the hob Advice on saving energy Use a pan with thick flat base. Curved bases increase energy consumption. Place a ruler on the base of the pan, if there are no gaps, the base of the pan is completely flat. The diameter of the base of the pan should fit the size of the hotplate. Check if the manufacturer has indicated the upper diameter of the pan. In general, this is greater than the diameter of the base of the pan. If the diameter of the pan does not fit the diameter of the hotplate, you are recommended to use a pan which is larger than the size of the hotplate, or else about half the energy will be lost. 6

7 Choose pans which are the right size for the amount of food to be prepared. A large pan which is half full will consume a lot of energy. Always centre the pan on the hotplate and always cover the pan with the matching lid. Cooking without using the lid quadruples energy consumption. Cook using small amounts of water. This will save energy and will also help green vegetables retain their vitamins and minerals. During their cooking, food such as stews, soups may heat up too quickly without any indication, spilling out of the cookware. It is therefore advisable to heat this type of food gently, selecting a suitable power level and stirring the contents before and during cooking. We recommend not to use for Induction hob pots that have been used in a gas hob fire can deform the flatness of bottom). In case of use, check that bottom is flat. 2. Installation instructions EH-DIH890 Cut-out Dimension 7

8 Important notes Safety in use is only guaranteed if the technical installation of the hob has been carried out correctly and in accordance with the installation instructions. The installation technician shall be liable for any damage cause as a result of incorrect installation. Only an authorized technician is able to connect the appliance. The guidelines set out by the electricity provider must be observed. This appliance should be used only with an earthed connection. Using this appliance without an earthed connection or after it has been incorrectly installated may, in very rare cases, cause serious harm. The manufacturer accepts no responsibility for any malfunction or damage which is caused by incorrect electrical installation. If the appliance is not fitted with an accessible plug, disconnecting means must be incorporated in the fixed installation, in accordance with the installation regulations. The power cable must be positioned so that it does not touch any of the hot parts of the hob. Refrigerators, dishwashers, ovens, or washing machines must not be installed under the induction hob. Any change to the appliance s interior, including changing the power cable, must be performed by the Customer Service. 8

9 Preparing the Kitchen The worktop should be flat and horizontal. The aperture should be cut before the appliance is installed. Remove any shavings, as these can affect the operation of the electrical components. When the cutting has been completed, the unit s stability should be checked again. Surfaces which have been cut should be sealed so that they are heat resistant and so that they do not swell when moist. The kitchen units to be fitted must resist temperatures of up to 90oC. The gap between the aperture and the side wall must be at least: 40 mm It is not recommended that the hob be placed between two side walls but, if this is the case, a gap of at least 200 mm should also be left on one side. If the induction hob is installed above a sterilizer there must be a gap of 70 mm from the top of worktop to the top of the sterilizer. If the induction hob is installed without sterilizer or above a drawer, the worktop thick around the hob must be 20 mm as minimum. If the interior width of the kitchen unit is less than 700 mm, a 80 mm long cut must be made in the side walls from the top section of the hob. Taking into account the hob ventilation: An aperture must be cut in the top section of the back of the kitchen unit, 680 mm wide and 45 mm high. There must be a gap of 20 mm between the back of the kitchen unit and the kitchen wall. if the hob is installed above a drawer, allow a gap of 65 mm between the drawer and the top section of the worktop. Installing and connecting the hob The earth wire ( green and yellow) should be connected first and disconnected last. It should also be longer than the others, so that even if the hob is moving the other wires can be disconnected before the earth wire. Connection diagram ( see figure) 1. Brown 2. Blue 3. Green and Yellow 9

10 Is required 16A electrical installation at customer s house (electrical circuit, socket and fuse ). Do not trap the lead during installation and do not guide it over sharp edges. The hob and the worktop should not be sealed with silicone as the hob itself has a seal which serves this function. Removing the hob Disconnect the cooker from the power supply. Push out the hob from below 3. Induction cooking Advantages of induction cooking Greater speed in cooking and frying; as the pan is heated directly. Reduced energy consumption Cleaner and easier to use; spilt food does not burn as much on the hob. Cooking control and safety; the hob supplies or cuts off the heat as soon as the controls are operated. The Induction hotplate stops supplying heat if the pan is removed before the power has been switched off. Suitable pans Ferromagnetic pans are the only pans which are suitable for induction cooking. They can be made of: enameled steel cast iron specially designed cookware for induction cooking made from stainless steel Special pans for induction cooking. Other types of special pans are available for induction cooking, where the base of the pan is not entirely ferromagnetic. Check the diameter as this could affect the pan detection as well as the cooking results. Checking pans using a magnet To find out whether the pans are suitable, check that they are attracted to a magnet. The manufacturer will usually indicate if their pans are suitable for induction cooking. Unsuitable pans. Never use pans made from: standard, high quality steel glass / earthenware copper / aluminum 10

11 Characteristics of the base of the pan The characteristics of the base of the pan can affect the evenness of the cooking. Pans which are made from heat-diffusing materials ( such as sandwich pans made from stainless steel) distribute the heat evenly, saving time and energy. No pan or incorrect size pan If no pan is place on the hotplate, or the pan is not made of a suitable material or it is not a suitable size, the heat setting on the hotplate indicator will flash. Place a suitable pan on the hotplate to stop the indicator flashing. If there is a delay of more than 90 seconds, the hotplate switches off automatically. Empty pans or pans with a thin base Do not heat empty pans and do not use pans with thin bases. Although your hob is equipped with an internal safety system, empty cookware can heat up so quickly that the automatic OFF function does not have time to react and a very high temperature may be reached. The base of the pan could melt and damage the hob s glass surface. If this happens, do not touch the pan and switch off the hotplate. If it does not work after cooling, contact our Local Service Center or dealer. Pan detection Each hotplate has a minimum limit for pan detection which varies according to the material from which the pan being used is made. It is for this reason you are recommended to use a hotplate which matches the diameter of the pan. Pan size detection Cooking zone 220mm 200mm Pan size minimum 130mm 90mm 11
