Lightning protection / Equipotential bonding of the building
In accordance with the lightning protection standard ÖVE/ÖNORM EN 62305 Part 1-4 the collector array cannot be
connected to the building's lightning protection. A safety distance of at least 1 m must be maintained from any pos-
sible adjacent conducting object. For installations on metal substructures at the installation site, generally qualified
electricians must be consulted. To carry out a building potential equalisation, the metal tubes of the solar circuit and
all collector cases or fastenings must be connected to the main potential equalisation bus by a qualified electrician
in accordance with ÖVE/ÖNORM E 8001-1 or the country-specific standards.
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 da-
mage 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 mi-
nimum 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.
