REPAIR

6.1

4i, 60-cm IV Induction

6.1.1

Disassembly of the appliance:

►

Remove the cooktop plate, thereby taking care not to damage
the installation pins.

►

Place the cooktop plate on the counter with the glass side
down. Be careful not to damage it.

►

Remove the 12 screws that fasten the frame/glass to the base

►

Position the frame/glass unit with the glass up.

6.1.2

Assembly of the appliance:

►

Fasten the frame/glass unit to the base using 12 screws.

►

Install the plate on the cooktop, thereby taking care not to
damage the installation pins.

Attention!

The power connections of the inductors are made using a ring lug and
a metric thread screw. Tighten the screw until the terminal cannot be
turned by hand. If the screw thread becomes stripped, the induction
electronics board will be useless.
