1.5 ASSEMBLY OF SOLAR COLLECTORS.
Assembly must only be performed on roofs or
frames that are strong enough. The strength of the
roof or frame must be checked on site by a struc-
tural engineer before assembly of the collectors.
The verification of the entire framework accord-
ing to the local Standards in force by a structural
engineer is necessary, especially in very snowy
areas or areas exposed to strong winds. Therefore,
all features of the installation area must be taken
into consideration (gusts of wind, formation of
whirlwinds, etc.), which can lead to an increase
of loads on the structures.
Normally, it is not necessary to connect the natu-
ral circulation system to the lightening protection
of the building.
Comply with the Standards in force in the
respective countries!
If the sub-structure is in metal, consult an expert
authorised on lightening protection. The metal
wires on the solar circuit must be connected us-
ing a wire of at least 16 mm 2 CU with potential
compensation main bar.
N.B. pay attention not to walk on the manifold
during all assembly phases (j).
N.B.: assemble the frame without tightening
the screws that will be tightened once the frame
has been fully assembled and before installing
the manifold and storage tank / Cylinder.
Before installing the system ensure that it has
been delivered in perfect condition; if in doubt,
contact the supplier immediately. Packing ma-
terials (staples, nails, plastic bags, polystyrene
foam, etc.) constitute a hazard and must be kept
out of the reach of children.
• Installation Standards:
- before starting the system, the solar collector
must be covered to protect the absorber from
overheating and the operator from any burns.
The system must only be filled after all the
hydraulic connections have been performed
correctly.
- During handling, use protective gloves and
avoid transporting the manifold gripping it by
its connection fittings.
Attention:
- it is obligatory to use the antifreeze supplied by
the manufacturer;
- the use of a storage tank unit involves the in-
stallation of a safety valve, an expansion vessel
and a one-way valve for the appropriately sized
domestic hot water circuit, these components
are not always included with the pack.
