Danger that may arise from the unit
DANGER!
Danger of electric hazard!
One may get in touch with live parts when the unit is open. Touching
live parts may cause severe injury or danger to life.
Prevention: Before carrying out any work set the Nordmann ES4 4 out
of operation as described in chapter 5.5 (switch off the unit, disconnect
it from the mains and stop the water supply) and secure the unit against
inadvertent powerup.
WARNING!
Hot water vapour - Danger of scalding!
The Nordmann ES4 4 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 ES4 4 immediately out of operation as described in
chapter 5.5. Correctly seal the steam system before putting the unit into
operation again.
WARNING!
Danger of burning!
During operation the components of the steam system (e.g. steam
cylinder, steam distributor) 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 ES4 4 out of operation as described in chapter 5.5, then wait
until the components have cooled down sufciently thus preventing dan-
ger of burning.
Behaviour in case of danger
If it is suspected that safe operation is no longer possible, then the Nor-
dmann ES4 4 should immediately be shut down and secured against
accidental power-up according to chapter 5.5. This can be the case
under the following circumstances:
– if the Nordmann ES4 4 is damaged
– if the electrical installations are damaged
– if the Nordmann ES4 4 is no longer operating correctly
– if connections and/or piping are not sealed

3.4 Functional description
The steam humidier Nordmann ES4 4 is a pressureless steam generator
that utilizes an electrode heating. The steam humidier Nordmann ES4 4
is designed for air humidication via a steam distributor.

Steam generation
Any time steam is requested, the electrodes are supplied with voltage via
the heating relay. Simultaneously, the inlet valve opens and water enters
the steam cylinder from the bottom via water cup and supply line. As soon
as the electrodes come in contact with the water, current begins to ow
between the electrodes, eventually heating and evaporating the water. The
more the electrode surface is exposed to water, the higher is the current
consumption and thus the steam capacity.
