GENERAL WARNINGS
The appliance’s electrical safety is guaranteed only when the
same appliance has been correctly earthed in compliance
with the regulations in force. The gas and water feeding pipes
and the CH system pipes cannot be used as ground plates.
Ensure that the above safety electrical requirements subsist;
in case of doubt, ask for a professionally qualified technician
to check the appliance’s electrical system.
UNICAL refuses responsibility for any damages arising from
failure to earth the boiler correctly.
It is necessary that a qualified technician verifies that the
electrical system is adequate to the appliance’s maximum
absorbed power, indicated on the data plate, verifying in
particular that the section of the system’s cables is suitable to
the appliance’s maximum absorbed power.
For the appliance’s general electrical supply the use of
adaptors, multiple sockets and/or extension cords is strictly
forbidden.
The use of any power supplied equipment implies the
observance of several fundamental rules, such as:
- Do not touch the appliance with any wet part of your body
and/or barefooted;
- Do not pull the supply cables;
- Do not expose the boiler to sunlight, rain, etc., unless it is
explicitly foreseen;
- Do not permit children or inexpert people to use the
appliance.
