Danger that may arise from the unit
DANGER!
Danger of electric hazard!
The Nordmann AT4 D is mains powered. One may get in touch with
live parts when the unit is open. Touching live parts may cause se-
vere injury or danger to life.
Prevention: Before carrying out any work set the Nordmann AT4 D out
of operation as described in chapter 4.4 (switch off the unit, disconnect
it from the mains and stop the water supply) and secure the unit against
inadvertent power-up.
WARNING!
Hot water vapour - Danger of scalding!
The Nordmann AT4 D produces hot water vapour. There is danger of
scalding when getting in touch with hot water vapour.
Prevention: Do not carry out any work on the steam system during op-
eration (steam lines, steam distributor, etc.). If the steam system is leaky
set the Nordmann AT4 D immediately out of operation as described in
chapter 4.4. Correctly seal the steam system before putting the unit into
operation again.
WARNING!
Danger of burning!
During operation the components of the steam system (steam cyl-
inder, steam distributor, etc.) get very hot (up to 100 °C). There is
danger of burning when touching the hot components.
Prevention: Before carrying out any work on the steam system set the
Nordmann AT4 D out of operation as described in chapter 4.4, then wait
until the components have cooled down sufciently thus preventing dan-
ger of burning.
Behaviour in case of danger

dmann AT4 D should immediately be shut down and secured against
accidental power-up according to chapter 4.4. This can be the case
under the following circumstances:
– if the Nordmann AT4 D is damaged
– if the electrical installations are damaged
– if the Nordmann AT4 D is no longer operating correctly
– if connections and/or piping are not sealed
All persons working with the Nordmann AT4 D must report any alterations
to the unit that may affect safety to the owner without delay.
