Avoid danger

The ROTEX E-SolarUnit is state-of-the-art and is built to meet all recognised technical requirements. However, improper use can
lead to serious injuries or death, as well as cause material damage.
To avoid such risks, only install and operate the ROTEX E-SolarUnit:
– as stipulated and in perfect condition,
– with an awareness of the safety and hazards involved.
This assumes knowledge and use of the contents of this manual, the relevant accident prevention regulations and the recognised
safety-related and occupational medical rules.
1.4

Proper use

The ROTEX E-SolarUnit must only be used as a hot water heating system. The ROTEX E-SolarUnit must be set up, connected and
operated in accordance with the stipulations contained in these instructions.
Any other use outside the above-mentioned use is considered as improper. Any resulting damages will be borne by the user/owner
alone.
Proper use also includes observing the relevant maintenance and servicing conditions. Spare parts must at least satisfy the
technical requirements defined by the manufacturer. This is the case, for example, with original spare parts.
