Viessmann VITOCELL 100-B, Техническое руководство

Страница: 16 / 144

3.2 Specification
The collectors are available with 2 different absorber coatings. Type
SV2D has a special absorber coating that allows these collectors to
be used in coastal regions.
Distance to the coast:
■ Up to 100 m:
Only use type SV2D
■ 100 to 1000 m:
Type SV2D is recommended
Note
Viessmann accepts no liability if Vitosol 200-FM, type SV2F/SH2F
are used in these regions.
