General and transport information
The installation may only be carried out by a qualified professional. The instructions provided here are directed at qual-
ified professionals only. The supplied materials must be used for the installation. Prior to installing and operating the
solar panel system, familiarise yourself with the standards and regulations valid at the site in question. We recommend
that you use a carrying strap to transport the solar collector. You must not lift the solar collector by its connections or
screw threads. Do not jolt the collector or allow parts of it to be affected by mechanical factors. This is particularly im-
portant for the glass, rear panel, and pipe connections.
Structural engineering aspects
The system may only be installed on a roof surface or substructure with a sufficient load-bearing capacity. The static
load-bearing capacity of the roof or substructure must be checked in accordance with local and regional stipulations at
the site prior to the installation of the panels, if necessary by means of the commissioning of a structural engineer. In
particular, it is important to check whether the quality of the (wooden) substructure is sufficient to enable the durability
of the screw connections for attaching the panel mounting apparatus. The onsite checking of the system (collectors and
attachment apparatus) as per EN 1991 and/or country-specific legislation is particularly important in areas prone to
heavy snow or high winds. All features of the installation site (foehn wind, venturi effect, vortex formation etc.) that
might result in higher stresses at the site in question must be investigated.
Information regarding flat roofs: The installation of a collector field is carried out on a (preexisting) roof. Attics with
a special construction or that are used for residential purposes and roof pitches that are below the minimum recom-
mended value require (in relation to the cladding) additional measures to be carried out by the customer in order to
protect against the penetration of water as a result of wind force and driving snow. This might include sub-roof mem-
branes, for example. When selecting the installation site, note that the maximum permitted loads must not be exceeded
as a result of snow or wind forces. To prevent inadmissible wind loads, the panels must not be installed at the edge of
a roof (e/10 zones as per EN 1991, but minimum gap of 1 m). Panels must not be installed below a height transition so
that it is not possible for excess loads to fall onto the panel system from the higher level as a result of drifting or sliding
snow. If, to solve this problem, snow catchers are installed on the higher level, the statics of the higher level must also
be checked.In the case of larger collector fields, we recommend that you mount the panels on a separate bearing struc-
ture made from steel profiles. Attachment using concrete ballast blocks enables the system to be installed without pen-
etrating the roof cladding. If the panels are mounted on concrete ballast blocks, rubber underlays must be used to
increase the static friction between the concrete ballast blocks, thus preventing damage to the roof cladding.
Lightning protection/building potential equalisation
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 leg-
islation by an authorised and qualified electrician.
Connections
Connect the collectors using the compression fitting screw connections. If no flexible tubes are available for use as con-
nection elements, make sure that the connecting piping allows for precautions to compensate for the thermal expansion
caused by temperature fluctuations, e.g.: Expansion bends and flexible piping (see the information on collector circuitry/
operating recommendations). In the case of larger collector fields, the intermediate placement of expansion bends/flex-
ible piping is required (CAUTION: Check the pump design). When the connections are tightened up, pliers or another
wrench must be used as a counter wrench in order to prevent the absorber from being damaged.
Collector inclination/general information
The collector is suitable for an inclination of between 15º and 75º. The collector connections and venting openings must
be protected so that water and contamination such as dust cannot enter them.
Guarantee
Guarantee claims are only valid if the system has been used in conjunction with the supplier's original frost protection
agents and if the system has been properly installed, commissioned, and maintained. The system must have been in-
stalled by a qualified professional and the installation instructions must have been followed without exception in order
for any claim to be valid.
