Fitting the mounting bracket
The collectors are connected to the structural element
using mounting brackets. The distances shown are using
the example of the mounting bracket for roof tiles.
B
Ensure there is safe access to the roof in compliance
with current legislation and health and safety
requirements.
Pre-assembly on the ground
In order to make installation on the roof easier for you, we
recommend that you pre-assemble the threaded
connections for all mounting brackets at ground level.
B
Secure the T-head bolt with washer and M10 nut onto
the mounting bracket.

Determining distances
B
In order to install the mounting brackets, you must
determine the distances for them. Please observe the
following guidelines (
Æ
Fig. 16):
– On tiled roofs, the position of tile valleys are used to
determine the true distance between the mounting
brackets.
– The rafter spacing does not always match the
required spacing for the mounting brackets. For
larger or smaller rafter spacing, you must install
suitable supports on site with adequate load-
bearing capacity (in doubt, consult a structural
engineer).
– For multiple rows of collectors, you must choose the
distances for the mounting brackets in such a way
that there is a minimum distance of 150 mm
between the collectors on the top and bottom.
– The mounting brackets must be positioned at right
angles to each other.
B
Define mounting bracket positions (

To prevent damage to the roof, do not
step on installed components.

An example of the mounting bracket for roof
tiles is shown in the following tables. The
distances also apply to other mounting
brackets.
NOTICE:
Collector damage through
incorrectly positioned mounting brackets.
B
Maintain the distance between the
mounting brackets (
Æ
B
Always choose the largest possible
distance between two vertical mounting
brackets (
Æ
Fig. 16, Dimension b).
B
A rafter width of at least 88 mm is required
to fasten the mounting brackets with
3 screws. Provide for on-site
reinforcements in case of narrower rafters.
