Safety regulations, instructions
and guidelines
The substructure as well as its connections to the
building have to be checked on site according to the local
regulations.
The collectors have to be mounted in an angle of at least
20° to max. 70°.
Recommended heat transfer medium is a mixture of glycol
and water, e.g. Tyfocor L or similar The collectors may
never be operated or tested under pressure with water.
To protect the system of overheating during standstill and
accelerated glycole-aging a self-draining system (e.g. STI
Drain Master or Drain Box) is recommended.
It is absolutely necessary to pay attention, that the back flow
temperature is never lower than the ambient temperature. If
necessary, take appropriate action (e.g. increase back flow
temperature to at least 30°C).
Lightning protection
Note country-specific legislation!
Throughout the installation of metal fastening, a check is
needed by an authorized qualified 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 sufficient ventilation for each assembly
method. Do not close the ventilation openings. Especially
in case of roof-integrated assembly, the ventilation of the
collector is definitely necessary. Appropriate ventilation
hoods are available from the supplier. Pay attention to the
regulations of the ZVDH (Germany), SVDW (Switzerland)
as well as different local regulations concerning the ventila-
tion. If necessary, consult an expert.
Responsibilites
The constructor of the installation is responsible for the in-
tegration of the installation according to regulations and for
compliance with the safety regualtions.
The operator of the installation is responsible for an ope-
ration of the installation according to regulations and for
consultation of experts in case of problems.
This instruction is not subjected to the control of a service of modi-
fications. 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 appropriate regulations and instructions.
Statics
Before beginning the assembly it is vital to test the roof or
substructure on site to sufficient load-carrying capacity.
Pay increased attention to the possible durability of the screw
fittings to fasten the collectors as well as to the quality of the sub-
structure.
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 sys-
tem construction, especially in snowy regions (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.
In case of correct assembly snow loads (pressure loads) up to 2
kN/m² and wind loads (suction loads) up to 1 kN/m² acting on the
collector are permitted.
For transport and stocking
Never abandon the delivered collectors unprotected at the building
site. Never lay down the collectors onto a rough surface with over-
hanging pieces like stones, timbers, etc.
Stock the collectors always upright leaning against a solid sur-
face.
The rigidity of the collectors is limited. During transport to the buil-
ding 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.
