Service Manual
Safety instructions
The following symbols 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
injury and material losses.
Danger through ‚live‘ electrical components.
Please note: 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 brings a risk of electrocution, which may
result in injury or death.
The main supply terminals are ‚live‘ even when
the ON/OFF switch is in the OFF position.
This indicates technical instructions which you
must observe to prevent material losses and
boiler malfunctions.
