Preparing and examining the façade
Check the installation location for the
following:
Repairs or refurbishment:
•
Check that the façade is in good con-
dition. Make sure that no work on the
façade is planned for the near future.
Façade design load
.
•
General design load for the façade as
relates to a tensile load.
•
Check to see if the façade structure is
strong enough to attach the hanger
bolts. If it is not, consult a structural
engineer.
Safety precautions
When installing panels on façades,
observe all applicable worker's com-
pensation board safety standards and
latest DIN-VDE standards.
Take necessary safety precautions to
prevent falls. Use scaffolding.
Determine the mounting location in
consideration of the following:
•
The collector panel should not be
shaded. Ensure that the eaves will
not shade the solar panel during the
summer.
•
Piping should be as short as possible
and be routed directly to the pump
assembly and heat storage tank.
•
To minimize wind loads, ensure that
the panel is not mounted close to the
edge of the façade. Minimum clear-
ance:
1.0 m;
more for higher build-
ings and exposed locations.
•
Keep the panel at least 1 m. away
from the eaves. Maintain this same
distance from the upper edge of the
building when the roof is flat. Increase
the distance for higher buildings and
exposed locations.
•
The distance between the fastening
points shall be individually calculated
taking into consideration the lengths
of the manifolds
AURON 15=138 cm
AURON 20 = 184 cm and the posi-
tion of the interconnecting plates
between the manifolds
and the bot-
tom rails. Note that a brace cannot be
positioned where the interconnecting
plate is located
F = 12 cm
The projection at the bottom is
G = 14 cm
and is defined by the
manifold
mounting bracket,
which prevents
slipping.
The upper projection (
E)
shall be in a
range between:
7 to 25 cm
and
A
= B: 140 cm is the maximum dis-
tance between supports.
The horizontal distance between the
fastening points
C = 135 to 168 cm.
(see summary on pages 23 and 24)
Collector panel length (D):
The total length of the collector panel is
the sum of the lengths of the individual
manifolds.
Length of AURON 15 DF manifold:
138 cm
Length of AURON 20 DF manifold:
184 cm
The floor bolts can be screwed into
façades which have timber beams. In
the case of concrete façades or brick
walls a suitable fixing element is to be
provided by others (e.g., injection an-
chor or shear connector). A structural
engineer must be consulted about this.
