1DEVICE INSTALLATION
1.1 DESCRIPTION OF THE DEVICE.
e Immergas solar solutions systems are sup-
plied complete for its commissioning with exclu-
sion of xing systems (e.g. plugs etc.).
e solar collectors are certied and are in com-
pliance with the standards Solarkeymark. ey
can be mounted on all roof types or directly on
the ground by means of an additional appropri-
ate structure.
e purpose of this manual is to give general
indications on its installation and relative use of
the complete system.
Installation must be carried out in compliance
with current regulations and by qualied sta.
Installation must be carried out according to the
standards, current legislation and in compliance
with local technical regulations and the enabled
companies.
In the event the pack is installed in damp places,
one must provide an insulation system under-
neath it, to insulate it from the ground.
e place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural) such to allow
(always in safety, efficiency and comfortable
conditions):
- installation (according to the provisions of the
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special ones);
- removal (to outdoors in the place for loading
and transporting the appliances and com-
ponents) as well as the eventual replacement
of those with appliances and/or equivalent
components.
Before installing the system, ensure that it is
delivered in perfect condition; if in doubt, con-
tact the supplier immediately. Packing materials
(staples, nails, plastic bags, polystyrene foam,
etc.) constitute a hazard and must be kept out of
the reach of children.
In case of failure to use the solar system or pro-
longed absences, cover the collectors to prevent
overheating of the system.
In the event of malfunctions, faults or incorrect
operation, turn the system o immediately and
cover it; it is also necessary to contact an author-
ised company (e.g. the Authorised Technical
Assistance Centre, which has specically trained
sta and original spare parts). Do not attempt to
modify or repair the appliance alone.Failure to
comply with the above implies personal respon-
sibility and invalidates the warranty.
“Anti-legionella” heat treatment of the Immergas
storage tank (activated by the specic function
present on the predisposed thermoregulatory
systems): during this stage, the temperature of
the water inside the storage tank exceeds 60°C
with a relative risk of burns. Keep this domestic
water treatment under control (and inform
the users) to prevent unforeseeable damage
to people, animals, things. If required install a
thermostatic valve on the domestic hot water
outlet to prevent scalding.
• Installation regulations:
- e control of the entire framework by a statics
expert, according to the Standards in force, is
mostly necessary in areas with large snowfall or
in areas exposed to strong winds. erefore, all
characteristics of the place of assembly must be
taken into consideration (gusts of wind, vortex
build-up, etc...) which can lead to an increase
of loads on the structures.
- before starting the system, the solar collector
must be covered to protect the absorber from
over-heating and the operator from eventual
burns. e system must only be lled when
all hydraulic connections have been coupled
correctly. It cannot be started until it is possible
to eliminate the heat generated by the solar
collector.
- e collector can be positioned on the basis of
the conditions of the roof (at or sloping) or in
a prepared free structure. e collector cannot
be positioned with the glass part facing down.
is causes malfunctioning and damage.
- Pay attention not to force or put excessive
traction on the collector connection ttings in
order to prevent damage tot he same and the
internal parts of the collector.
- During movement, use protective gloves and
do not transport the collector holding it by the
connection ttings.
Attention:
- it is in fact obligatory to use antifreeze supplied
by the manufacturer;
- when realising the hydraulic circuit (pipes,
ttings, etc.), only use suitable materials that
resist high temperatures and are suitable for
use with solar systems.
- the use of a boiler involves the installation 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 in the package.
N.B.: if errors occur during installation, running
and maintenance, due to the non compliance of
technical laws in force, standards or instructions
contained in this book (or however supplied by
the manufacturer), the manufacturer is excluded
from any contractual and extra-contractual
liability for any damages and the warranty is
invalidated.

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.
- e collector can be positioned based on the
roofs conditions (at 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. e system must only be lled 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
ttings.
- 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 qualied rm, in compliance with the legisla-
tion in force, which must issue a declaration of
conformity.

1.15 CIRCULATION UNIT HYDRAULIC
CONNECTION.
e device is pre-assembled before delivery. e
pipes for connection must be ordered separately.
To avoid any vapour entering the expansion
vessel, position the expansion vessel lower than
the collectors. If the vessel is positioned above
the collectors height, it must be connected by
means of a particular pipe to prevent the vessel
from heating up (this pipe, which is not supplied
by Immergas, interrupts the laminar circulation).
Every time the system is emptied, it must be
rinsed well with running water. e circulation
unit is not designed for use in direct contact with
swimming pool water.
1.16 ASSEMBLY INSTRUCTIONS.
a) remove the device from the insulation casing
by removing the front and rear halves.
b) drill two holes Ø 8 on the wall in correspond-
ence with the holes on the supporting plate.
c) x the supporting plate to the wall by placing
the rear half of the insulation casing.
d) connect the circulation group fittings in
accordance to the indications of the gures
using the ttings kit supplied separately. If
using copper pipes or pipes of limited physical
resistance their terminals must be reinforced.
e terminal part of the pipe must be cut
perpendicular in respect to the pipe axis and
cleaned.
e) Mount the safety valve unit on the circulation
unit. e safety valve outlet must be connected
to a draining funnel. Otherwise, the manu-
facturer declines any responsibility in case of
ooding if the drain valve cuts in.
f) Connect the electric cable of the circulation
unit as indicated in the respective manual of
the control unit, positioning it at the centre of
the device.
g)Cover the circulation unit with the front case
previously removed.
