2.1 General information
For
- Installation,
- Commissioning and
- Service
of the boiler: this may be performed by qualified and
trained personnel only. In accordance with VDE 0105 Part
1, work on electrical components (e.g. control unit) may
only be carried out by qualified electricians. VDE/ÖVE
regulations [Germany/Austria] and those of your local
power supply utility company are applicable to electrical
installation work. Only operate the boiler within its output
range, which is stated in the technical documentation
supplied by WOLF. Appropriate use of the boiler refers
to the exclusive use for hot water heating systems in
accordance with EN 12828. Never remove, bypass or
otherwise disable any safety or monitoring equipment.
The boiler must only be operated if it is in perfect working
order. Any faults or damage which impact or might impact
safety must be remedied immediately by a qualified
contractor. Only replace faulty components and equipment
with original WOLF spare parts.
2.2 Danger from "live" electrical components
Never touch electrical components or contacts when the
ON/OFF switch is in the ON position. There is a danger of
electrocution, resulting in a risk to health or death. The
main terminals are 'live', even when the ON/OFF switch is
in the OFF position.
Before removing the casing
- I solate the system from the power supply (e.g. by
removing the separate mains fuse or by means of a
mains electrical isolator or heating emergency stop
switch) and check to ensure that there is no voltage.
- Safeguard the system against reconnection.
