  1. Welcome you to the training TheINDUCTION HOB

  2. ANALOGY WITH THE TRANSFORMER DeschaJ: Stacking up of iron strip = empilement de lames de metal

  3. THE SKIN EFFECT Principle In a wire In the pan Resulting current Bottom of the pan Density of current Thickness of the pan

  4. Gas Cast iron Radiant Halogen Induction 10 20 30 40 50 60 70 80 90% EFFICIENCY comparative rate It results significant energy savings

  5. QUICKNESS OF HEAT RADIANTHALOGEN GAS CAST IRON INDUCTION Time required to bring 2 litres of water from 20°C to 95°C

  6. QUICKNESS OF COOLING RADIANTHALOGEN GAS CAST IRON INDUCTION Decreasing to 60°C after boiling 2 litres of water

  7. THE PANS If you choose a pan with this logo, you will be certain that it is absolutely compatible with your induction hob under normal condition of use • The compatible induction pans must be made of a magnetic material : • Enamelled steel pans with or without non-stick coating • In cast iron with or without enamel coating • In ferrous stainless steel – laminated stainless steel • In aluminium with special bottom We advise to choose pans with a thick bottom and a minimum diameter of 12 cm (i.e. 5 inches) for even more cooking : the heat spreads more evenly

  8. Diameter announced by the pan manufacturer Bottom diameter THE PANS 190mm 160mm « Crown effect» Pan Inductor 160mm & 180mm Middle crown : 2800W maxi External crown : 1800W maxi Inductor 280mm "Krone"

  9. FITTING Fixing supplied with the hob SEAL

  10. FITTING ABOVE A UNIT WITH A DOOR OR A DRAWER 1- In case of a small cross piece, there is no problem 2- In case of a rectangular cross piece or with a closed top, make a bevelled cut so that air comes out of the hob 3- In case of an intensive using with more than 1 cooking zone, we advise to make an opening on both sides of the unit

  11. FITTING ABOVE AN OVEN Oven in lower position Oven in upper position Other brand of oven Same brand of oven

  12. FITTING ABOVE A DISHWASHER The top of the dishwasher must be covered with an insulation plate (77X7781). Ensure that there is a minimum opening of cool air.

  14. ELECTRICAL CONNECTIONS

  15. ELECTRICAL CONNECTIONS

  16. ELECTRICAL CONNECTIONS 230 V single live Connect the 3 cables on your installation, observing the correct cable colours 400 V 2N three lives Connect the 4 cables on your installation, observing the correct cable colours

  17. USINGSetting 9, 12 or 15 levels of power from 50 to 2800W A ‘Booster’option function enables the cooking zone to reach 3600W

  18. USING Continuum zone 4600W

  19. USING Allow to memorize a complete cycle of cooking (maximum 5 different power/time) "STARTCONTROL" End of cooking programmed (maximum power 6) HU (HEAT UP)

  25. THE KEYBOARDSwith capacitive keys High frequency signal

  26. THE CURRENT FILTER • Protections against over-current due to the work of the hob • Stop the outside and inside interferences • Stop the outside over current

  27. THE FILTER IX3 and IX3WR Earth screw Fuse tracks Direct live Live wire Neutral via the relay Neutral Direct neutral Command Relay 15V= Supply of the fan Power relay

  28. THE RECTIFIER Filter rectifier After rectifier Before rectifier Filter rectifier • Bialternation rectifier by diode bridge • Filtering of high frequencies by condenser Outside current 310 V= when hob doesn’t work

  29. THE TRANSISTOR INVERTER V/2 Inductor Rectified current V V/2 • 2 power transistors • 2 condenser • 2 diodes
