Assembly instructions
The collectors must be secured on the roof be-
cause loose installation frames can be knocked
over and damaged by the wind. First check the
structural suitability of the substructure and the
permissible surface load for the roof cladding
(consult a structural engineer if necessary).
To avoid damaging (drilling through) the roof
cladding, you can use weights (e.g. Roth gravel
plate set, concrete ties) to weigh it down.

The installation engineer bears sole
responsibility for ensuring that the collectors
are adequately anchored on open ground or on
the roof, particularly if the location is subject
to strong winds. Any data pertaining to weight
