Instructions for installation and transport
The installation may only be carried out by qualified personnel. Please inform yourself about the applicable local
norms and regulations before mounting and operating the solar system. Only the supplied material should be used
for the installation. 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.
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 con-
nections.
Structure
The collectors may only be mounted on sufficiently load-bearing roof surfaces and substructures. 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 sta-
bility of the screw joints necessary for installing the collectors. In particular, it is essential to have the entire col-
lector structure verified at the installation site according to DIN 1055, Part 4 & 5 or according to country-specific
regulations in regions with heavy snowfalls (Note: 1m³ powder snow ~ 60kg/1m³ wet snow ~ 200kg) and strong
winds. 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
As per the stipulations of Lightning Protection Standard EN 62305 Parts 1 to 4, the collector field must not be
connected to the building's lightning protection. Beyond the scope of validity of this standard, country-specific
legislation must be observed. A safety gap of at least 1 m from any adjacent object that may be conductive must
be left. In the case of installations on top of existing metal substructures, an authorised and qualified electrician
must be consulted. To enable potential equalisation of the building, the metallic conductor pipes of the solar circuit
and all of the collector housing/fixtures must be connected to the main equipotential busbar in accordance with
EN 60364 and/or country-specific legislation by an authorised and qualified electrician.
Connections
Depending on the design, the collectors must be connected with one another and/or the connection pipes using
screw fittings (1" internal thread) with flat-face sealing. Optimally, the collectors can be connected via a brazing
connection (special accessories CUVB). 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 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 20° (minimum) and 65° (maximum).
Given adherence to the following conditions, the collector can be used up to an angle of 15°:
->
The collector must only be installed in areas that do not normally experience snowfall!
->
If the collector is covered with snow in exceptional cases, the snow must be removed quickly!
->
The collector array must be enclosed with the cover envisaged for this purpose (15°)!
