How to replace the PCB interference filter
Version 11.2005 and The modification on the PCB interference filter is relevant
later only for units with heating.
On this PCB there is a separate plug contact for each electric
heating connection. On units with more than one heating
element, the heating elements were connected with separate
plug distributors up until 10.2005. This is no longer necessary.
The heating element(s) is/are now directly connected to the
plug contacts on the PCB interference filter.
