GENERAL SAFETY INFORMATION

9
Check that the product is complete, undamaged and as or-
dered as soon as you receive it. Report any discrepancies or
damage to our dealer who sold it.
9
This product must be installed by a legally qualified heating
engineer. On completion of the installation, the installer must
issue the owner with a declaration of conformity confirming
that the installation has been completed to the highest stand-
ards in compliance with the instructions provided by us in this
instruction manual, and that it conforms to all applicable laws
and standards.
9
This product must only be used for the purpose for which it is
designed and made, as specified by us. We decline all respon-
sibility, contractual or other, for damage to property or injury
to persons or animals caused by improper installation, adjust-
ment, maintenance or use.
9
All servicing and repairs must be performed by a qualified
heating engineer.
9
Solar collectors must be installed with the correct mounting kit
(which includes all necessary rails and brackets) as listed in
the Catalogue.
9
The system must be installed by specialist personnel. Use
only the assembly material supplied with the solar collector.
The supporting framework and all masonry or brickwork fixing
points must be checked by a person expert in static loading,
and must be suitable for the nature of the installation site.
9
The solar collector must only be installed on roofs or frames
that are strong enough to support its weight. The strength of
the roof or frame must be verified on site by a person expert in
static loading before the solar collector is installed. During this
process, it is important to verify the suitability of the supporting
frame to hold the screw fasteners that fix the solar collector
in place. An expert in static loading must verify that the entire
frame complies with relevant standards, especially in areas
liable to snow and areas exposed to high winds. Conditions
(gusts of wind, formation of wind vortices, etc.) at the point
where the solar collector is to be installed must be carefully
considered since these can increase the loads on the support-
ing structure.
9
Solar collector pipes must be connected through a (yel-
low-green) connector of at least 16 mm
the potential compensation main bar. If a lighting rod is already
installed, collectors can be integrated in the existing system.
If this is not the case, it is possible to carry out earthing with
a buried earth cable. The earth duct must be laid outside the
house. Furthermore, the earth cable must be connected to the
compensation bar through a duct having the same diameter.
9
All pipes in the water circuit must be insulated in conformity to
relevant standards. Lagging and insulation must be protected
against damage by the weather and birds and animals.
9
The collector is suitable for a minimum inclination of 15°, up to
a maximum of 75°.

This instruction manual is an integral part of the product. It
must be kept safe and must ALWAYS accompany the product,
even if it is sold to another owner or transferred to another
user or to another installation. If you lose this manual, order

Size the solar expansion tank so as to ensure complete ab-
sorption of the expansion of the fluid contained within the sys-
tem, with reference to the prevailing regulations on the mat-
ter. In particular, consider fluid characteristics, considerable
fluctuation of service temperature and vapour that might be
generated during solar collector stagnation stage. Proper size
of expansion tank ensures setting off of all volume changes of
the heat transfer fluid, avoiding excessive pressure increase.
Limited pressure changes avoid reaching safety valve opening
pressure and the consequent fluid drainage.
Always wear safety goggles when drilling. Always wear safety
shoes, cut-proof protective gloves and a safety helmet when
performing installation work.
Before beginning installation work on roofs, install the neces-
sary fall prevention and fall arrest devices and ensure that all
applicable safety standards are applied. Use only tools and
materials that conform to the safety standards that are applica-
ble in the place of work.
Use only overalls with harness (with lacing or restraining belt,
connection ropes or bands, fall dampeners, heat sinks) certi-
fied for the risk detected according to the type of covering and
allowing operating in complete safety.
The use of ladders leaned against walls can lead to serious falls
if the ladder slips, slides of falls. When using ladders, always
ensure that they are stable, and that suitable ladder stops are
present. If possible secure the ladder with hooks. Make sure
that there are no live electrical wires near the ladder.
Never attempt to install the system without using suitable per-
sonal protection equipment and without following all applicable
occupational safety standards.
Do not touch the product when barefoot or wet if it has any
electrical accessories installed in it.
If solar plant pressure decreases, it is forbidden to top up with
only water as there is a danger of freezing and overheating.
Do not dispose of packaging material into the environment,
or leave it within the reach of children, since it can become a
potential hazard. Dispose of packaging material in compliance
with applicable legislation.
