INSTRUCTIONS FOR USE
AND MAINTENANCE.
2.1 CLEANING AND MAINTENANCE.
The system can develop high temperatures dur-
ing the hours of irradiation, especially if there is
no DHW withdrawal, with evident heat stress. It
is therefore necessary to prescribe yearly main-
tenance of the system, thus allowing to keep the
safety features, yield and functioning that distin-
guish it, unaltered through time. The Immergas
conventional warranty assumes that the user has
periodic maintenance of his system performed
by an Authorised Technical After-sales Centre.
Maintenance operations on the system performed
by unspecialised staff, not supplied with the
necessary safety devices, when the system is not
connected to earth, are prohibited.
Attention:
the Solar Systems must undergo
periodic maintenance
(ref. chap. 3)
.
This ensures that the optimal safety, performance
and reliability characteristics of the boiler, which
distinguish the Immergas natural circulation
system, remain unchanged over time.
We recommend stipulating a yearly cleaning
and maintenance contract with an authorised
local company.
The frequency and methods of maintenance on
the Immergas Solar Systems leave any control
and maintenance obligations prescribed by
national, regional or local provisions in force
not prejudiced.
2.2 GENERAL WARNINGS.
In the event of prolonged lack of DHW with-
drawal from the solar system (prolonged absence,
holidays etch.) the safety valve may intervene
causing dispersion of water, or that the system
overheats, damaging itself.
The safety valve outlet must be connected to a
draining funnel. On the contrary, if the drain
valve should intervene flooding the place of in-
stallation, the solar system manufacturer cannot
be held responsible for any damage/injury to
objects/persons.
To prevent overheating of the collector in the
event of non-use, the Solar collector must be
covered.
Failure to cover or withdraw water, especially in
the summer, can lead to the necessity to vent the
circuit and top-up the heat carrying fluid.
At the end of its service life, the appliance must
not be disposed of like normal household waste
nor abandoned in the environment, but must
be removed by a professionally authorised
company. Contact the manufacturer for disposal
instructions.
