Important Notes
Danger

This presents the danger of severe scalds to the whole body.
Before removing the electrode make sure that the boiler pressure is zero bar.
The electrode becomes hot during operation. Touching the hot equipment presents the
risk of severe burns to hands and arms. All installation and maintenance work must only
be performed when the equipment is cold.

Retrofitting and maintenance work must only be performed by qualified staff – who through adequate
training – have achieved a recognised level of competence.

The name plate specifies the technical features of the equipment. Note that any piece of
equipment without its specific name plate must neither be commissioned nor operated.
