General and transport instructions
The mounting system is suitable for tiled roofs only. Installation must only be carried out by qualified personnel.
The entire information in these instructions is intended exclusively for such qualified personnel. Only the supplied
material should be used for the installation. Prior to starting installation and operation of the solar collector sys-
tem, please inform yourself about the applicable local standards and regulations. The use of a carrying strap is
recommended for transporting the collector. The collector must not be lifted at the connections or on the th-
reading. Avoid impacts and mechanical influences on the collector, in particular on the solar glass, the rear panel
and pipe connections.
Statics - flat roof
The collectors may only be mounted on sufficiently load-bearing roof surfaces and substructures. It is imperative
that the static load bearing capacity of the roof or substructure is checked in terms of local and regional conditions
prior to installation of the collectors by the customer, if necessary through the involvement of a structural
engineer. Particular attention should be paid to the quality of the (timber) substructure in terms of the stability of
the screw connections necessary for fastening the collectors. The checking of the entire collector structure by the
customer as per DIN 1055 part 4 and 5 or as per the applicable country-specific regulations is particularly im-
portant in areas with heavy snowfall (note: 1 m³ powder snow ~ 60 kg / 1 m³ wet snow ~ 200 kg) or in areas
exposed to high wind speeds. The assessment should also take into account any particular circumstances at the
place of installation (foehn wind, air jets or eddy formation etc.) which can lead to increased loads. As a rule,
collector arrays must be installed such that any possible collection of snow is prevented from reaching the collec-
tors by snow barriers (or through special forms of installation). The distance to roof ridges/edges must be at least
1 m.
Note: The installation of a collector array is an intervention into a (existing) roof; above all, converted and inhabi-
ted loft spaces or roofs with less than the minimum slope (with regards to the covering) require additional mea-
sures by the customer, e.g. sarking membranes, as protection against water penetration caused by wind pressure
and driving snow. With larger collector arrays, we recommend installing the collectors on a special supporting
structure made of steel channels. Alternatively, it is possible to install the collectors without perforating the roof
membrane by using concrete ballast with guys. The collectors are mounted on concrete blocks. Rubber mats
should be used if necessary to protect the roof membrane against damage and to increase the friction between
the roof and the concrete blocks. In addition, it is necessary to secure the collectors with 5mm steel cables
(minimum tensile strength 1450 N/mm²) to absorb any peak wind loads.
Lightning protection / Equipotential bonding of the building
In accordance with the lightning protection standard ÖVE/ÖNORM EN 62305 Part 1-4 the collector array cannot
be connected to the building's lightning protection. A safety distance of at least 1 m must be maintained from any
possible adjacent conducting object. For installations on metal substructures at the installation site, generally
qualified electricians must be consulted. To carry out a building potential equalisation, the metal tubes of the solar
circuit and all collector cases or fastenings must be connected to the main potential equalisation bus by a qualified
electrician in accordance with ÖVE/ÖNORM E 8001-1 or the country-specific standards.
Connections
Depending on the design, the collectors must be connected with one another and/or the connection pipes using
screw fittings (1" internal/external thread) with flat-face sealing. Ensure correct placement of the flat gaskets. If
flexible pipes are not used as connectors, precautions must be taken to protect the connection pipes against tem-
perature fluctuations caused by heat expansion, e.g. expansion bends and flexible piping (see Connecting the coll-
ectors to one another/Operational recommendations). Larger collector arrays must be assembled with expansion
bends or flexible members inserted in the links. (IMPORTANT: check the pump design). When tightening the union
nuts, always balance (counter) the torque with a pipe wrench or another spanner to prevent damage to the absor-
ber.
Collector angle / General notes
The collector is suitable for angles between 15° (minimum) and 75° (maximum). The collector connections and the
ventilation openings must be protected against the penetration of water as well as against contamination through
dust etc.
Legal guarantee
Legal guarantee claims can only be made if the supplier's own antifreeze has been used and maintenance has been
carried out correctly. Installation by qualified personnel with absolute adherence to the instructions is a prerequisite
for the justification of claims.
