1 - GENERAL SAFETY WARNINGS
Installation, modications
The installation must be carried out by professionally
qualied people, in compliance with national and local
regulations, as well as with the instructions given in this
manual.
Incorrect installation or bad maintenance can cause injury
or damage to people, animals or things, for which the
manufacturer cannot be held responsible.
A domestic hot water temperature of higher than 51°C
can cause injury or damage, even of a permanent nature,
to people, animals and things. In particular, children, the
elderly and the disabled must be protected against any
possible risks of scalds, by inserting devices that limit the
temperature of use of the DHW to users.
Do not leave packaging and replacement parts within
reach of children.
The user, in line with the arrangements for use, is obliged
to maintain the system in good order and to guarantee
reliable and safe operation of the equipment.
The user is obliged to have maintenance of the system
carried out according to national and local regulations
and according to the arrangements of this brochure, by a
professionally qualied engineer.
Before performing any cleaning or maintenance operations,
disconnect the storage tank from the mains power supply
and/or activate the relevant isolation devices.
After completing any cleaning or maintenance operation,
before reconnecting the electric power supply, make sure
that all the internal parts of the storage tank have been
properly dried.
This storage tank cannot be used by people (including
children) with reduced physical, sensorial or mental
capacities or with little experience and knowledge unless
they are tested and instructed on the use of the storage
tank by the person responsible for their safety.
This brochure is an integral and essential part of the product
and must be retained carefully by the user for possible
future reference. If the storage tank has to be replaced or
if you have to move and leave behind the storage tank for
another user, always make sure that this brochure is left
for the new user and/or installer.
Any eventual optional extras or kits added later must be
Cosmogas originals.
This storage tank must be used only for the purpose for
which it was expressly intended: the storage of hot water
for domestic and sanitary uses for civil use.
The constructor bears no contractual or non-contractual
responsibility for damage caused by errors in the installation
or use and also where the instructions given by the
manufacturer himself, or the applicable national and local
laws, are not observed.
For reasons of safety and environmental protection, the
various pieces of packaging must be disposed of in suitable
recycling centres.
In the event of a fault
In the event of a fault and/or poor operation of the storage
tank, disconnect it and do not attempt to carry out any repair.
Contact only a professionally qualied engineer. If components
need to be replaced, these must be original spare parts.
Should this be ignored, the safety of the equipment may be
compromised.
Professionally qualied engineer.
By professionally qualied engineer we mean someone having
specic technical skills in the sector of components of systems
for heating and the production of hot water for hygienic and
sanitary uses in a civil context, electrical systems, and systems
for the use of exhaust gases. Such people must have the skills
envisaged by the law.
Technical drawings
All the drawings shown in this manual, relating to electrical,
hydraulic or gas installation systems, must be understood to
be purely illustrative. All the safety devices, auxiliary devices
as well as the diameters of the electrical, hydraulic and gas
pipes, must always be checked by a professionally qualied
engineer, to make sure they satisfy the applicable laws and
regulations.
1.1 - National installation laws
Respect the national regulations, provisions, directives and
laws in force.

2.3 - Disposal
The crossed wheelie bin symbol means that the product
must not be thrown away in the ordinary rubbish bin (i.e. in
with “mixed urban rubbish”); it must be dealt with separately,
in order to undergo suitable operations for it to be reused or
treated, so that any substances that are dangerous for the
environment can be removed and disposed of safely. This
will enable all the raw materials to be recycled. The user
is responsible for getting rid of the unit at the end of its life,
delivering it to Recycling Centres run by the local authority or
city hygiene companies.
For further information regarding correct decommissioning
of these units, users can contact the public service in charge
or retailers.
