Touching live parts can result in an electric shock and lead
to potentially fatal injuries and burns.
▪ If there is an electric immersion heater or an external
current anode installed in the hot water storage tank,
these components must be isolated from the power sup-
ply before starting work (e.g. fuse, main switch switched
off and secured against inadvertent switching on again).
