Safety Instructions - Wolf CGB-75 Maintenance Instructions Manual

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 risks and
injuries to individuals and material losses.
Danger through '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.
"Note" indicates technical instructions that you
NB
must observe to prevent material losses and
boiler malfunctions.
General notes
Maintenance work must only be carried out by a
qualified heating contractor.
Regular maintenance and the exclusive use of original
Wolf spare parts are necessary preconditions for
trouble-free operation and a long service life.
We therefore recommend you arrange a maintenance
contract with a local heating contractor.
