Installing the mounting rack
Flat roof type E: Outdoor / flat roof assembly using mounting
rack with adjustable angle of inclination.
Determine fastening points
taking into consideration the following:
•
The collector panel should be orient-
ed to face southward.
•
The collector panel should not be
shaded at any time.
•
The interconnecting piping should be
kept as short as possible and be rout-
ed directly to the pump assembly and
heat storage tank.
•
In order to minimize wind load, panels
should not be installed directly at the
edge of the roof.
Minimum clearance: 1.2 m;
More for higher buildings and exposed
locations.
•
The distance between the fastening
points shall be individually calculated
taking into consideration the length of
the manifold
(AURON 15 = 138 cm)
(AURON 20 = 184 cm) and the posi-
tion of the interconnecting plates be-
tween the manifolds and the bottom
rails. Note that a brace cannot be
positioned where the interconnecting
plate is located
F = 12 cm
•
Do not exceed the following
dimensions:
projection
E: 7 to 25 cm
and
maximum distance between
supports
A: 140 cm
The total depth of the mounting frame:
B = 150 cm
(see pages 21 and 22)
Preparing and inspecting the roof
Check the roof for the following:
•
roof does not leak or need repairs;
there are no plans to refurbish the
roof in the immediate future
•
The way the mounting racks are fas-
tened depends on the roof's design
load rating. In some cases this may
require that a structural engineer cal-
culate the requirements, taking into
consideration the relevant snow and
wind loads.
•
When the mounting rack is fastened
to concrete weights, the roof must be
capable of supporting an additional
300 kg/m². Concrete slabs weighing
300 kg shall be used to weigh down
each collector. Use construction pro-
tection mats to protect the roof cover-
ing.
•
If the ballast weight is any less, the
panels shall be tied down using wire
rope fastened to fixed hold-down
points. The calculations shall be done
by a structural engineer.
•
The mounting racks may also be bolt-
ed to girders that transmit the load to
walls capable of supporting the total
weight.
•
Concrete slabs, bolts and anchors for
attaching the mounting racks are not
included in the scope of supply and
shall be supplied at site by others.

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
