IMPORTANT:
Failure to follow the installation instructions and the notes contained
therein will lead to all liability being refused by Webasto. The same
applies if repairs are carried out incorrectly or with the use of parts other
than genuine spare parts. This will result in the invalidation of the type
approval for the heater and therefore of its homologation / EC type
licence.
