3. Installation and maintenance
3.1 Safety guidelines
The installation must be implemented in accordance with European, National and Local standards in force
pertaining to system safety, by qualified expert personnel.
Qualified expert personnel refers to persons with specific technical skills in the sector pertaining to heating
system components in civil applications and hot water production, as required by Italian Law No. 46/90 dated
5/03/1993, Legislative Decree No. 37 dated 22/01/2008, subsequent updates and implementation Decrees.
The manufacturer shall not bear any contractual or non-contractual liability for damage caused by errors in
installation and use, and in any case deriving from non-compliance with European, National and Local Laws
and Standards in force and instructions provided by the manufacturer.
All safety standards must be complied with when installations are implemented on a roof, so as to safeguard
the workers and persons, who during the works can be at risk due to falling objects or similar.
Starting with the positioning of the ladder, this must rest against secure points and lean at an angle between
65° and 75°. It must also be higher than at least 1 m from the landing point. The ladder must be secured in
order not to slide, give-way and/or tip over. It is recommended to use rung ladders up to a height of 5 m.
Passage-ways, areas where persons can stop and work stations that are beneath the area in question must
be protected against objects that can fall. Block, close off and mark the areas that present hazardous
situations for people. Protections is required starting from 3 m if the solar collectors are to be installed on a
roof with an inclination between 15° and 60°. Fall protection can consist of scaffolding, assembled with a
max difference of 5 m between the worktop and the scaffolding or the roof protection wall, which must
protrude laterally a minimum of one metre on each side with respect to the work area.
Should the scaffolding or the roof wall not be sufficient to guarantee a safe installation, safety harnesses can
be used and these must be firmly anchored to solid construction parts, possibly above the user.
3.2 Orientation of the collectors
For maximum energy performance from the solar collectors, these must be installed with the sunlight
absorbing surface facing the south. This orientation can be changed if the energy need is concentrated in the
morning (exposure south-east) or in the afternoon (exposure south-west). When positioning the solar
collectors, verify that they are not covered by shade caused by other buildings or trees, when seasons
change. For example, a roof slope can be entirely exposed to the sun during the summer months (when the
sun is in the highest position with respect to the horizon) and be completely in the shade during the winter
months when the sun is at its lowest, or vice versa.
