Notes before starting assembly
The installation and initial operation must be carried
out by an expert who is responsible for the correct
installation and operation.
Before installing and putting the collectors into service,
please inform yourself about the local engineer
standards and regulations.
For mounting the collecor you should use the available
mounting hook. The mounting hooks can be xed at
the planned installation site with any suitable mounting
system for solar thermal or photovoltaic modules. (in
dependence of roof shape and roong)
Please contact your supplier of xing material.
Throughout the installation of a solar collector you directly
intervene into an existing roof cladding. Di󰀨erent roof
coverings such as tile, shingles or slate require additional
measures (eg sarkings) as security against the ingress
of moisture due to rain or snow - especially in case of
extended and occupied top oors or in case of too less
roof pitch (concerning the covering).

Safety regulations, instructions
and guidelines
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.

Initiation
Any guarantee and warranty for collectors as well as for resulting damages on the system or building expires due to
unauthorized changes on the collectors and the accessoiries.
There is no guarantee or warranty due to optical or technical reduction or defects on the collector resulting from external
inuences, forasmuch as these inuences are not part of the supplier’s sphere of inuence and they are not explicitly
known before execution.
Important to observe!
Initial operation
After installing the other components such as ow pipe,
return pipe, insulation, pump group, expansion tank and
controller the installation can be put into service. Perform
a leak test and complete the commissioning log.
Protect the collectors from direct sunlight if the lling of the
installation is not carried out within ve days after comple-
tion of the assembly.
Inspections within the rst two weeks of
operation
• bleeding the solar circle.
• control system pressure
Instructions for the operation of the
installation
Carry out changes to the scheme and other system
components only after consultation and with inputs from
your specialized partner.
Ensure that an appropriate safety valve is mounted,
whose opening pressure is not exceeding the maximal
operating pressure of the collectors.
Furthermore, do not install shut-o󰀨 valves that may a󰀨ect
or prevent the funtion of the safety valve.
Carry out maintenance and inspectionw with appropriate
caution.
Certain components may reach temperatures up to 200°
C. There is a risk of burns.
It is absolutely necessary to make sure that the back ow
temperature never falls below the ambient temperature.
If necessary, take appropriate measures (e.g. increase of
back ow temperature to at least
30° C.)
Regular inspections
Solar systems should be reviewed at intervals to be determined in
addition to the function control by the operator.
The maintenance intervals of the system will be dened during
commissioning.
An annual review is recommended. The following components
must be checked for proper function (if installed):
• solar collectors
• solar circle
• heat transfer uid
• solar storage
• solar regulator incl. circulation pump
• supplementary heating system
Unscheduled maintenance
Depending on the location of the installation, environmental
inuences may cause soiling on the collector glass (dust, pollen
etc.). Clean the glass, if necessary, exclusively with clear water to
ensure optimal light transmission.
If it is necessary to free the system from snow or ice, use only
non-metal cleaning equipment, such as brooms, with due care.
Walk on roof areas only in compliance with all safety aspects.
Heavy condensation may occur on the interior side of the glass
when defrosting while the collectors are covered with snow. It is
absolutely necessary to free the collectors from snow to avoid
damages due to humidity.
