For a better visual appearance, posi-
tion the lower rail as low as possible
on the roof anchor.
• Make sure that the mounting rails are fixed
in horizontal position.
• Compensate any difference in height by
moving the clamping elements.
• Pull the clamping element upward, now it
can be moved and it engages again when
released.
• Place the collector with the lower edge on
the mounting rail and hook it to the clamp-
ing elements.
• Make sure that the upper part (1) of the
clamping element is above the collector
edge.
• Tighten the clamping elements of the
lower mounting rail with the socket/combi-
nation wrench (SW 13).
Caution!
a
After tightening the clamping ele-
ments, make sure the tension is cor-
rect by shaking the upper part of the
clamping element. If it can be moved,
retighten the nut.
