1 Statutory regulations governing installation
1.1. Statutory regulations governing installation
The Thermo 90 S / Thermo 90 ST heater has been type-tested and
approved in accordance with EC Directives 72/245/EEC (EMC), 2001/
56/EC (heater) and ECE R122 with the following EC permit numbers:
e1*2001/56*2004/78*0005*--
e1*72/245*95/54*1173*--
e1*2001/56*2004/78*0019*--
E1 R122 00 0217
Primarily the regulations of Annex VII of the Directive 2001/56/EG and
Part 2 or Annex 7 of the directive ECE R122 must be observed for the
installation.
NOTE:
The provisions of these Directives are binding within the territory
governed by EU Directive 70/156/EEC and should similarly be
observed in countries without specific regulations.
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.
