Operational conditions

a Caution!
The roof may collapse!
Mount the flat collectors only on roofs with a
sufficient load-carrying capacity.
If necessary, call a technician.
Caution!
Collector damage!
Flat collectors are suitable for a maximum
snow load of 5.0 kN/m
2
load of 1.6 kN/m .
On-roof mounting:
The flat collectors can be mounted on roofs with inclina-
tions from 15º to 75º.
Flat roof installation:
Flat collectors can be installed on flat roof frames in the
as-delivered condition with an angle of 30°, 45° or 60°.

CE mark

The CE mark certifies that the appliances, according to
the models available, satisfy the basic requirements of
the following directives:
– Directive 97/23/EWG of the European Parliament and
Council for approximation of the laws of the member
states regarding pressure equipment
auroTHERM flat collectors are built accord-
ing to the state of the art and recognised
safety rules and regulations.
Conformity with the applicable standards
has been demonstrated.
auroTHERM flat collectors have been suc-
cessfully tested according to the rules and
requirements for the Solar Keymark.

Safety information 3

Danger!
H
Danger of burning and scalding!
In case of solar irradiation inside the units, col-
lectors can reach 200 °C. Remove the sun pro-
tection film installed at the factory only after
the solar energy system has been started up.
H Danger!
Danger of burning and scalding!
In case of solar irradiation inside the units, col-
lectors can reach 200 °C.
Do not perform maintenance work under direct
sunlight.
a Caution!
Risk of corrosion!
On roofs made of metals more noble than alu-
minium (e.g. copper roofs) galvanic corrosion
can occur at the anchor points, whereby the at-
tachment of the collectors is no longer guaran-
teed. Ensure that the metals are separated by
suitable underlays.
Caution!
Collector damage!
In order to install flat collectors according to
the installation manual, a qualified engineer is
required.
The installation should be performed only by
qualified engineers.
