1.10 SOLAR COLLECTORS.
The installation of a heating solar collector
requires analysis of a range of issues (installa-
tion area, positioning, inclination angle, etc.), of
which depend on the performances the collector
will be able to supply once started.
It is therefore important to contact a an author-
ised company to check the various parameters
installation.
Installation precautions:
- Before installing the collector, proceed with an
installation area check, ensure the installation
of the collector can withstand atmospheric
agents: wind and snow.
- The collector can be positioned based on the
roofs conditions (flat or leaning) or in a predis-
posed adjustable structure. Under no circum-
stances can the collector be positioned with the
collector glass facing downwards which is the
cause of the malfunctions and damages.
- before starting the operating system, the solar
collector must be covered to protect the ab-
sorber from overheating and the operator from
scalding. The system must only be filled when
the hydraulic system of the collector has been
assembled and cannot be started before it has
been possible to eliminate the heat generated
from the solar collector.
- Be careful to not force or put the connection
fittings under excessive traction to avoid
damaging them and the internal parts of the
collector.
- During handling use appropriate personal pro-
tective equipment (e.g. gloves etc.) and avoid
transporting the collector from the connection
fittings.
- Provide an appropriate earthing system con-
nection and any lightning and surge protection
systems to safeguard any electric devices. In
the event these systems are already present,
the Immergas solar system must be connected
to the existing lightning protection system by
a qualified firm, in compliance with the legisla-
tion in force, which must issue a declaration of
conformity.
