For each number of collectors and col-
lector combination, a specific number of
rafter anchors or fixing brackets (in con-
nection with sheet steel roofs) is alloca-
ted.
Subject to the distance between rafters,
use a specific number of rafters for
installing the rafter anchors.
The following tables detail the rafters on
which the rafter anchors or mounting
brackets should be fitted.
Example:
■ Number of collectors 3
■Combination comprising 1 x 2 m2 and
2 x 3 m2
■ Rafter distance 600 mm
