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 con-
nected to the building's lightning protection. Beyond the scope of validity of this standard, country-specific legisla-
tion 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
The collectors are equipped with four screw connections (1 ¼" male thread) and must be connected with flat sealing
to each other or to the system connection pipes. Ensure correct placement of the flat gaskets. Length compensators
must be used as connection elements between the collectors in order to compensate the length expansion of the
copper pipes during temperature fluctuations. Provided that the length compensators are used, up to 11 collectors
can be connected in series (ATTENTION: Check the pump design or the flow differences in the individual collectors).
When tightening the connections with the spanner, a torque of 30Nm should not be exceeded so as to prevent
damage to the manifold or absorber.
Collector angle / General notes
The collector fixing systems are designed to be assembled at 30°, 45° and 60°. The collectors are suitable for a
minimum angle of 25° and a maximum angle of 75°!
The collector connections and the ventilation openings must be protected against the penetration of water as well as
against contamination through dust etc.
Warranty
Warranty claims can only be made if the supplier's own antifreeze has been used and maintenance has been carried
out correctly. Installation by qualified personnel with absolute adherence to the instructions is a prerequisite for the
justification of claims.
Installing the sensor
The sensor immersion sleeve must be installed on the solar supply, i.e. on the upper manifold of the last collector
connected in the series. If there are several series of collectors which are combined in a circuit, the sensor
immersion sleeve must be installed on the solar supply, i.e. on the upper manifold of the last collector connected in
the series farthest away from the pump.
