Electrical connection The installation must be carried out by an approved
electrical contractor. Observe VDE regulations as well
as all local regulations of your power supply utility.
Danger due to ‘live’ electrical components.
Please note:
Switch OFF the omnipolar isolator before removing
the casing.
Never touch electrical components or contacts when
the isolator is in the ON position. This carries a risk
of electrocution that could result in injury or death.
No mains isolator on the appliance. When working on
the boiler, always ensure that there is no voltage by
opening the omnipolar isolator or removing the ex-
ternal mains fuse.
- Switch OFF the heating system at the omnipolar isolator or the
external mains fuse of the control unit. Please note: It is not
possible to isolate the appliance from the power supply using
the operating mode button.
- Close the gas ball valve or the main gas tap.
Shutting down the
heating system
Emergency shutdown The fuse in the installation room or the heating emergen-
cy stop switch may only be used to switch off the heating
system in an emergency.
- In the event of danger, e.g. re, disconnect the heating system
from the power supply using the heating emergency stop switch
or the relevant mains fuse.
- Shut off the gas supply using the gas ball valve on the boiler or
the main gas tap on the gas meter.
