GENERAL RECOMMENDATIONS
• is document is an integral and essential part of the product. It is to be used by the installer and the end user, who must
keep it carefully aer the system has been installed and started.
• e manufacturer is not liable for any damage deriving from incorrect observation of the instructions and indications
given in this document, those relative to possible accessories supplied with the system and for the non-observance of
pertinent applicable national and local laws.
• Before installation and use, obtain information on the current regulations and laws in the place where the system is to be installed.
• e SOLARSMART solar collector with integrated storage was designed and manufactured to produce domestic water that is
heated by solar power. Any use other than that indicated relieves the manufacturer from any responsibility and renders all gua-
rantees null and void.
• All technical drawings, plant layout and electric wiring diagrams etc. that are present in this manual are indicative and are only given
as examples. All connections, the safety devices, diameter sizes and any other thing necessary for correct system installation must
be veried by a qualied and expert technician, who must make sure of their correspondence with regulations and laws in force.
• e manufacturer is not liable for any damage caused to the product resulting from assembly that is not state-of-the-art.
INDICATIONS FOR SAFETY
• is product must be installed by a professionally qualied company or technician, according to national and/or local
laws in force and the instructions given in this handbook.
• Maintenance and cleaning must also be carried out by specialist companies or sta with the pertinent technical quali-
cations.
• e term ‘professionally qualied technician’ indicates a person with specic technical skills in water for domestic use,
as well as in heating systems, gas systems and electric systems. is person must have the professional skills indicated by law.
• On the basis of the user guidelines, whoever uses the system must keep it in good condition and guarantee that it works safely
and correctly.
• e system user must ensure that the maintenance indicated in this handbook (see the Programmed maintenance chapter) is
carried out.
• Do not leave parts of the packaging or the system within the reach of children.
• Before cleaning or carrying out maintenance, disconnect the power supply from any electric accessories that may be present.
• Dispose of the various packaging elements in a suitable manner.
• Check the pressure of the water transportation network: if the pressure is higher than the nominal pressure of the product (4 bar =
400 kPa), prepare the necessary reduction units before the connection and regulate the pressure (see Hydraulic connection chapter)
• Should faults occur, or if the system does not operate correctly, do not attempt to repair the product. Instead, disable it and contact
a specialist technician. Should it be necessary, components must only be replaced with original spare parts, which must be installed
by qualied technicians. Should this not be the case, the manufacturer reserves the right not to recognise any guarantee rights.

e manufacturer declines all liability due to printing or transcription errors, reserving the right to make any modications to its
technical and commercial documents without forewarning.
e company IMMERGAS S.p.A., with registered oce in via Cisa Ligure 95 42041 Brescello (RE), declares that the design, manufac-
turing and aer-sales assistance processes comply with the requirements of standard UNI EN ISO 9001:2015.
For further details on the product CE marking, request a copy of the Declaration of Conformity from the manufacturer, specifying the
appliance model and the language of the country.
PROTECTION FROM VACUUM OVERHEATING
• e SOLARSMART solar collector with integrated storage is supplied equipped with a PVC cover sheet which darkens
the surface that collects the sun’s rays, therefore protecting the product against overheating caused by direct exposure,
above all in the case when the collector has been installed but is not connected to the water system (therefore no water
present). e collector, in fact, was not designed to be exposed directly to the sun’s rays without being lled with water.
• Exposure to the sun when the system is empty can damage the product; in this case the manufacturer will not recognise
any guarantee rights.
• e cover sheet must be le on the solar collector until it is started (see also the Starting chapter). Should it be necessary to empty
the system for maintenance or as a no-freeze function, it should be covered by the cover sheet (white part towards the collector).
PROTECTION FROM BURNS
• Danger! e water inside the collector can reach temperatures of approximately 90 °C. To prevent the danger of
burns and/or scalds, be extremely careful when:
- connecting the hydraulic supply to the domestic water supply;
- loading and unloading the system;
- carrying out any intervention on the hydraulic connection
Always position a thermostatic mixer valve between the system outlet and the domestic water user (see Hydraulic connection
chapter).
• In general, do not touch the transport pipes or the hydraulic connections and the internal accumulation tanks while the system
is operating.
• Should it be necessary to empty the system while it contains hot water:
- do not discharge directly onto the roof or into the ground;
- use a exible hose to safely lead the water to a drain.
PROTECTION AGAINST LIGHTNING
• Pursuant to the Directive EN 62305 1-4, the SOLARSMART solar collector with integrated storage must not be
connected to the protection system used by the building against lightning, unless indicated otherwise by local laws
in force.
• Have a technician or skilled electrician check the installation area for this possibility.
• All metal structures that are present, therefore also the supporting structure and xing shas of the system, must have
the same electric potential as the building. It is therefore good practise to prepare suitable earthing for the metal parts of
the system.
• is can be done by a skilled electrician and the evaluation of the equipotentiality level evaluated by a skilled electrical engineer.

1INSTALLATION.
1.1 GENERAL INDICATIONS AND MOVING.
Assembly, maintenance and cleaning must only be
carried out by companies and specialist sta.
e components indicated in this handbook must be
used when assembling. e use of other material is
under the responsibility of the installer, who assumes
full responsibility, including the product guarantee.
e manufacturer is not liable for any work not carried out in
a state-of-the-art manner, and for any damage caused to the
structure or the tools used.
Before installing and using the system, it is advisable to check
local regulations and laws to make sure that what is described
in this document complies with them. Should they be dierent,
do not install the system and contact the manufacturer.
e manufacturer is not liable for any damage caused to things
and injury to people as a result of installation carried out wi-
thout respecting local regulations and laws.
e system can only be moved when empty and extre-
mely carefully. Do not use or apply force to the plastic
threaded connections in order to li the product.
Avoid knocks and pressure on the system, in particular
on the cover, base and the plastic connections that
project from the frame.
Do not place any load on the system.
When moving, always use people who are competent,
trained and equipped according to what is imposed by laws in
force. Always use means of transport, liing devices, chains
and any other things that are of a suitable capacity and size.
1.2 STRUCTURAL CHECK.
e SOLARSMART solar collector with integrated
storage can be placed on the ground or on a structure
(attic, covering, balcony, etc...) that can support the
device weight and dynamic actions caused by varia-
ble things (e.g. wind, snow,...), considered with the
presence of “SOLARSMART” solar collector with
integrated storage.
In the case of already-existing buildings in par-
ticular, all combinations of the static capacity of
the structural elements and anchors used must be
carefully evaluated, according to what is indicated in
the technical standards for construction (NTC 2008, in Italy),
or the Eurocodes (EN 1991, in Europe). is check must be
carried out by a structural technician who is authorised to work
in the installation area.
Be very careful of the load increase caused by snow
or strong wind. e manufacturer is not responsible
for damage to things or injury to people caused by
bad installation on structures that cannot support
the indicated loads.
1.3 SAFETY PRECAUTIONS WHILE ASSEMBLING.
Danger caused by wind
Install when the weather conditions
are good, avoid rainy days and strong
winds.
Risk of falling from a height
Solar systems oen need to be installed
at a height. Operators must follow regulations
and laws in force regarding safety.
Danger caused by hanging loads and
material falling from a height
If material needs to be lied using a crane or
machinery, apply all the pertinent recommen-
dations and regulations in order to carry out
these operations safely. Use suitable means of
the correct capacity. Mark o the area where
the liing is being carried out, to prevent risks
caused by objects falling from a height.
