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

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

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.

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) ?
