Statutory regulations and safety
instructions
In principle, the general accident prevention regulations and
current works safety instructions are applicable. The "Gen-
eral safety regulations" that go beyond the scope of the
above regulations are stated below.
Any special safety regulations relevant to this instruction
manual will be highlighted in the relevant sections or text
passages of the procedures.
1.4.1 Statutory regulations governing installa-
tion
The Dual Top heaters have been type-tested and approved
in accordance with EC Directives 72/245/EEC (EMC) and
2001/56/EC (heater) with the following EC permit numbers:
e1 03 5000
e1 00 0195.
Installation is governed above all by the provisions in Annex
VII of Directive 2001/56/EC and the regulations in the instal-
lation instructions.
NOTE
The provisions of these Directives are binding within
the territory governed by EU Directive 70/156/EEC and/
or 2007/46/EC should similarly be observed in coun-
tries without specific regulations!
Installation of the Dual Top RHA 101/102 heater and related
components must be in accordance with IEC 60364 (“Elec-
trical installations in caravan parks and caravans”).
IMPORTANT
Dual Top RHA 101/102: you have to be certified to work on
230 V electric systems. Installation and all other jobs carried
out by none certified persons can cause personal injury to
you, the Dual Top and the vehicle. In that case, Webasto will
refuse all liability.
IMPORTANT
Failure to follow the installation instructions and the notes
contained therein will lead to all liability being refused by We-
basto. 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.
NOTE
For vehicles with an EU permit, no entry in accordance with
§ 19 Sub-Section 4 of Annex VIII b to the Road Traffic Act is
required.

documentation thoroughly.
