General and transport information
The installation may only be carried out by a qualifi ed professional. The instructions provided here are directed at
qualifi ed professionals only. The supplied materials must be used for the installation. Prior to installing and opera-
ting 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 aff ected 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 suffi cient 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 suffi cient to enable the durabili-
ty 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-specifi c legislation is particularly important in areas prone
to heavy snow or high winds. All features of the installation site (foehn wind, venturi eff ect, 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 fi eld 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 roofi ng 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 fi elds 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 fi eld must not be con-
nected to the building's lightning protection. Beyond the scope of validity of this standard, country-specifi c 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 qualifi ed 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/fi xtures must be connected to the main equipotential busbar in accordance with EN 60364 and/or country-
specifi c legislation by an authorised and qualifi ed electrician.
Connections
Depending on the execution, the panels are to be connected with each other and/or to the connecting pipework by
means of fl at sealing and using screwed fi ttings (internal/external thread). It is important to make sure that the fl at
gaskets are properly seated. If no fl exible 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 fl uctuations,
e.g.: Expansion bends and fl exible piping. In the case of larger collector fi elds, the intermediate placement of expan-
sion bends/fl exible piping is required (CAUTION: Check the pump design). Please ensure that there is suffi cient strain
relive (no pulling force) on the connecting pipes and that they are fl exible. When the connections are tightened up, an
additional spanner must be used as a counter-tool, in order to prevent the absorber from being damaged . Danger of
breakages!
Pipeline system
Caution: The collector connections and the input and output lines can reach very high temperatures during operation
or when stagnant! The input and output lines under roof must be fi tted with temperature-resistant (>150°C) insula-
ting material .
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 .
Warranty
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 qualifi ed professional and the installation instructions must have been followed without exception in order
for any claim to be valid .
