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 CU2 - INDUCTION – 001UK -0305, Diapositive N°7

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

DIAGNOSTIC IX3, IX3WR, IX4000

2 A.S.S. keyboards  IX3 with 6 wire cables  IX3WR, IX4000 with 8 wire cables

Failure of the command  Systematic using of the ASS keyboard Failure of the command even though ASS keyboard is used  Is the filter card supplied ? (IX3 and IX3WR)  Is the power card supplied ?  Is the power relay (fitted on the filter card) commanded ? (IX3 and IX3WR)  Is the power relay switched on ? (working of the fan) ? (IX3 and IX3WR)

CU2 - INDUCTION – 001UK -0305, Diapositive N°33

DIAGNOSTIC IX3, IX3WR, IX4000 Failure of the ventilation  In case of « overheating error » message, is the installation correct ?  Is the fan mechanically locked ?  Is the fan supplied ? (12V= or 230V~ depending on the product)

In case of failure on just one of the inductor  Check firstly the connection between the power card and the inductor.  Is the repartition relay commanded (Clic-Clac) ? (IX3,IX4000)  Is there a detecting pan problem on one of the cooking zones ? (IX3WR) Reminder : the level ‘inverter and detection’ is doubled on the IX3WR cards.

In case of detecting pan failure :  Is the magnet test ok ?  Is the pan included in ‘Class induction’ list  Has the pan the minimum diameter required (generally 12cm) ?
