Statics
Before beginning the assembly it is vital to test the roof or
substructure on site to su󰀩cient load-carrying capacity.
Pay increased attention to the possible durability of the
screw ttings to fasten the collectors as well as to the qua-
lity of the substructure.
According to DIN 1055 part 4 and 5 or rather according to
the local engineer standards it is necessary to check on
site the whole collector installation, especially in snowy re-
gions (note: 1 m² powder snow ~ 60 kg / 1 m² wet snow ~
200 kg) as well as in regions with high wind speed. Before
starting the assembly all aspects that may lead to incorrect
load of the whole construction have to be considered.
Install the collectors the way that backlog of snow (e.g.
due to snow guards or other obstacles) is not possible.
The collectors have to be mounted in an angle of at least
20° to 70°.
In case of correct assembly snow loads up to
2 kN/m² and wind loads up to 1,1 kN/m² on the collector
are permissible.
There must be a minimum distance of 1 m to ridge of the
roof, dormer and eave.
For transport and stocking
- Never abandon the delivered collectors unprotected at
the building site.
- Never lay down the collectors onto a rough surface with
overhanging pieces like stones, timbers, etc.
- Stock the collectors always upright leaning against a
solid surface.
- The rigidity of the collectors is limited. During transport
to the building site always ensure a torsion-free transport
type.
- In case of an elevated intermediate storage make sure
that the collectors are protected against sliding down.
The selected substructure and the connections to the
building are to be interpreted by others according to local
circumstances.
Recommended heat transfer medium is Tyfocor LS or
equivalent. The collectors may never be operated or
tested under pressure with water.
Part of the collector can reach temperatures above 200°C
and can cause burns.
The collectors are not to be mounted or lled in direct
sunlight.
Disregard of the instructions can lead to the extinction of
the warranty.
Lightning protection
Note country-specic legislation!
Through the installation of metal fastening, a check is
needed by an authorized qualied electrician.
The metallic pipes of the solar circle are connected via
a copper pipe of at least 16 mm² with the earth circuit
connector.
Please ensure su󰀩cient ventilation for each assembly
method. Do not close ventilation openings. The collector
has to be ventilated behind.
Pay attention to the regulations of the ZVDH (Germany),
SVDW (Switzerland) as well as di󰀨erent local regulations
concerning the ventilation. If necessary, consult an
expert.
Responsibility
The constructor of the installation is responsible for the
integration according to regulations and for compliance
with the safety regulations.
The operator of the installation is responsible for an
operation of the installation according to regulations and
for sonsultation of experts in case of problems.
This instruction is not subjected to be control of service
of modications. It does not absolve the manufacturer
and operator of the installation of his responsibilities to
install and operate all parts of the installation according
to utmost professional knowledge. The manufacturer of
the installation is responsible to observe and keep all
apropriate regulations and instructions.
