The following symbols and references are used
in conjunction with these important instructions
concerning personal safety, as well as operational
reliability.
"Safety instructions" are instructions with
which you must comply exactly, to prevent
risks and injuries to individuals and material
losses.
Danger from 'live' electrical components!
NB: Switch OFF the ON/OFF switch
before removing the casing.
Never touch electrical components or
contacts when the ON/OFF switch is in
the ON position! This results in a risk of
electrocution that may lead to injury or
death.
The main supply terminals are 'live' even
when the ON/OFF switch is in the OFF
position.
Parts of boilers can get very hot;
consequently there is a risk of serious
burns.
Therefore allow to cool down prior to
installation work.
This requires an action.
Visual check.
