Instructions for installation and transport
The roof bracket mounting system is suitable for tiled roofs only. The installation may only be carried out by
qualified personnel. Only the supplied material should be used for the installation. Please inform yourself about
the applicable local norms and regulations before mounting and operating the solar system. Note: Installing a
collector array signifies an intervention into an existing roof. Roof coverings, e.g. tiles, shingle and slate, especially
in the case of converted and inhabited loft spaces or roofs with less than the minimum slope (with regards to the
covering), require additional on-site measures, e.g. sarking, as security against water penetration caused by wind
pressure and driving snow. This substructure and its connections to the main building structure should be
designed at the installation site in accordance with the local conditions. The roof structure must be able to take
the wind and snow loads that can occur in the respective region. If snow loads are higher than 2.3kN/m² a metal
tile must be mounted beneath the roof bracket.
The use of a carrying strap is recommended for transporting the collector. The collector must not be lifted at the
connections. Avoid impacts and mechanical action on the collector, especially on the solar glass and the pipe
connections.
Structure
The collectors may only be mounted on sufficiently load-bearing roof surfaces and substructures. It is essential
that the structural load-bearing capacity of the roof and the substructure must be tested at the installation site
before mounting the collectors. Here, particular attention should be paid to the quality of the (timber) substructure
in terms of the stability of the screw joints necessary for installing the collectors. In particular, it is essential to
have the entire collector structure verified at the installation site according to DIN 1055, Part 4 & 5 or according
to country-specific regulations in regions with heavy snowfalls and strong winds (Note: 1m³ powder snow ~ 60kg
/ 1m³ wet snow ~ 200kg). The assessment should also take into account any special features of the particular
site that could lead to increased loads (foehn wind, air jets or eddy formations, etc). Collector arrays should always
be installed in such a way that any possible snow piles caused by snow trap grids (or the position of the collectors)
do not reach the collectors. There must be at least 1m distance from roof ridging or edges.
Lightning protection / Equipotential bonding of the building
It is not necessary to connect collector arrays to the lightning protection of the building (please observe the
country-specific regulations). For installations on metal substructures at the installation site, authorized lightning
protection specialists must be consulted. The metal tubes of the solar circuit must be connected to the main
potential equalization bus by means of a conductor (green/yellow) with a cross-section of at least 16mm² CU (H07
V-U or R). It is possible to ground the collectors to a ground rod. The grounding line must be laid outside the
house. The ground rod must also be connected to the main potential equalization bus by a line with the same
cross-section as above.
Connections
(screw connections)
Connect the collectors (SCE200) using the cutting ring screw connections. The collectors (SCE250) must be
connected with one another and/or the connection pipes using screw fittings (¾" internal/external thread) with
flat-face sealing. Ensure correct placement of the flat gaskets. If it is not intended to use flexible pipes as
connecting elements, precautions must be taken to protect the connection pipes against temperature fluctuations
caused by heat expansion (expansion bends/flexible piping). In this case, no more than 6 collectors may be
connected in series. Larger collector arrays must be assembled with expansion bends or flexible members inserted
in the links (IMPORTANT: check the pump design). When tightening the connections, always apply counter-
pressure with a wrench or another spanner to prevent damage to the absorber.
Collector inclination / General notes
The collector is suitable for angles between 15° (minimum) and 75° (maximum).
Steps must be taken to ensure that water and other contaminants such as dust, etc. are prevented from getting
into the collector connections and ventilation holes.
Warranty
Warranty claims can only be made if the supplier's own antifreeze is used and maintenance is carried out correctly.
