Safety and unexpected risks
Risks could arise at the exploitation of the system:
The hot water boiler of series “ELTHERM” is designed and produced according to
the safety requirements of the operating European standards and norms. However
safety and unexpected risks could arise in situations like following:
•
Hot water electric boiler of series “ELTHERM” is operating incorrectly;
•
The electric power supply does not comply with the requirements of the
electric boiler (i.e. its voltage as well as frequency);
•
The system is installed by unauthorized/unqualified personal;
•
The safety instructions, described in this manual are not followed and
fulfilled;
Unexpected risks:
The hot water electric boiler of series “ELTHERM” is designed and produced
according to the requirements of the operating EU safety norms. However, in spite
of that possible risks are considered as a result of the operating process of the
boiler, it is possible to arise risks as follows:
•
Electrical shock risks at indirect contact. The boiler is connected to the
power circuit and its operating module is separated in specialized electric
control box, equipped with required protective and short-circuits preventive
devices. It is obligatory to perform boiler ground connection by authorized
personal/technician;
