Tips for use

• If you operate the hotplates without pots and pans, you will damage the product.
• Place the pots so that they are centered on the hotplates. When you want to put the pot in another cooking zone, lift it instead of sliding it to the desired cooking zone.
• Do not use unstable and easily tipped utensils on the hob. Do not place pot or pan lids on hot plates.
• Do not place aluminum and plastic containers on the appliance as it may be hot.
• Thaw frozen food before cooking. Splashes can damage the hob surface and cause a fire.
• Never fill the pan more than one-third full of oil. Do not leave it unattended while heating the oil. Extremely hot oil is a fire hazard. If oil catches fire, cover it with a fire blanket or wet cloth. Turn off the stove if it’s safe to do so.
• Do not let any objects fall onto the hob. Even small objects can damage the hob. If the surface is damaged in any way, for example, visible cracks, switch the product off immediately to reduce the risk of electric shock.

WARNING: The pot and pans are very hot! Take care when removing it from the hot plate. If necessary, wear heat-protective gloves.
