Important Notes
Danger
When loosening the electrode live steam or hot water might escape.
This presents the danger of sever scalding.
It is therefore essential not to dismantle the electrode unless the boiler pressure is
verified to be zero.
The electrode is hot during operation.
This presents the risk of severe burns to hands and arms.
Installation and maintenance work should only be carried out when the system is cold.
Usage for the intended purpose
