8.9 Repair of spare parts
Repair of spare parts and of whole units may only be effected by INDUCS Ltd. Therefore
you have only to check and replace parts that are described in this service manual.
If you should repair parts, please describe exactly the faults if possible with information
about the history of the unit, for example new installation, changements which have been
done next to the induction cooker or to other units which are supplied by the same network.
In order to save transport charges, do not return defective parts as temperature sensors,
rectifier, transistor modules, interrupters. Such parts can be disposed correctly on place.
