The following symbols are used in this
document to highlight special information
and warnings. These important instructions
relate to personal safety and general ope-
rational safety of the equipment.
"Safety Instructions" must be strictly
followed to prevent the risk of endan-
gering or injuring persons or causing
material damage to the equipment.
Danger from 'live' electrical compon-
ents.
NB: Switch off the main ON/OFF switch
before removing any panels.
Never reach into electrical compon-
ents or touch any electrical contacts
when the main ON/OFF switch is tur-
ned on! Otherwise you risk a harmful
or potentially fatal electric shock.
A voltage will still be present at the
mains terminals when the main ON/
OFF switch is turned off.
"NB" indicates technical instructions
which you must observe to prevent
material losses and boiler malfunc-
tions.
