General and transport instructions
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 system, please inform yourself about the applicable local standards
and regulations. We recommend using an assembly crane for transporting the collector. The collector must only be
lifted via the pre-mounted lifting rings and must not be lifted at the connections. Avoid impacts and mechanical in-
fluences on the collector, in particular on the solar glass, the collector rear panel and pipe connections.
Statics
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 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 (EN 1991-1 part 4 and 5) or as per the applicable country-specific regulations is particularly im-
portant in areas with heavy snowfall (note: 1m³ powder snow ~ 60kg / 1m³ wet snow ~ 200kg) or in areas exposed
to high wind speeds (see table "Reactions to requirements"). The assessment should also take into account any par-
ticular 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 collectors by snow barriers (or through special forms of installation). The distance to roof ridges/
edges must be at least 1m.
Note: The installation of a collector array is an intervention into a (existing) roof; above all, converted and inhabited
loft spaces or roofs with less than the minimum slope (with regards to the covering) require additional measures by
the customer, e.g. sarking membranes, as protection against the penetration of water through 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 ne-
cessary to protect the roof membrane against damage and to increase the friction between the roof and the ballast
blocks. If the dimensions of the concrete ballast blocks are adhered to as per the table below, no additional securing
through steel cables is required. If the total weight (total weight of the concrete ballast blocks and maximum possible
snow load) exceeds the static load bearing capacity of the substructure, a combination of lighter concrete ballast
blocks plus additional 5 mm steel cables (minimum tensile strength 1450N/mm²) can be used for securing.

If concrete ballast is used whose weight is below that given in the table above, additional securing with
steel cables (5mm / min. tensile strength 1450N/mm²) is required!
