General and transport information
The installation may only be carried out by a qualified professional. The instructions provided here are directed at qualified
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 important 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 sloping roofs: The installation of a collector field is carried out on a (preexisting) roof. Roof claddings such as
tiles, shingle, and slate, attics with a special construction or that are used for residential purposes, and roof pitches that are below
the minimum recommended 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 membranes, for
example. To prevent overloading the roof cladding/joints (for hanger screws and roof clamps), metal roofing must be used from a
characteristic snow load of > 1.25 kN/m². When selecting the installation site, note that the maximum permitted loads must not be
exceeded as a result of snow or wind forces. As a general rule, collector fields must be installed in a way that allows snow to freely
slide off. Any accumulations of snow as a result of the use of snow guards (or the peculiarities of the installation site) must not be
able to reach the panels. Snow catchers must be installed 0.5 m above the top of the panels to ensure that the panels themselves
do not act as snow arrestors. 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). In particular in the case of elevated structures, the top of a panel must not protrude above
the roof ridge. 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.
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 legislation 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 connection
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/flexible 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 installed by a qualified
professional and the installation instructions must have been followed without exception in order for any claim to be valid.
