4.6 Taking the unit out of operation
In order to take the Nordmann Omega steam generator out of operation (e.g. for maintenance purpose),
perform the following steps:
1. If maintenance work on the water system of the Nordmann Omega is to be carried out, the steam
tank must be emptied. Proceed as follows:
a. Switch off the Nordmann Omega via the unit switch.
b. Wait 5 seconds, then switch the Nordmann Omega on again. If the drain pump starts, wait 60
seconds (with the Omega Medium 100 seconds) until the steam tank has been emptied. If the
drain pump does not start automatically within 10 seconds (e.g. because of a pump failure), drain
the steam tank manually via the manual drain hose (see step 5 ).
2. Close the shut-off valve in the water supply line.
3. Switch off the Nordmann Omega via the unit switch (if not yet switched off).
4.
Disconnect Nordmann Omega from the mains : Switch off the electrical isolator(s) in the mains
supply line(s) and secure switch(es) in " Off " position against accidentally being switched on, or
clearly mark the switch.
5. If you have to carry out work on the water system: Loosen the retaining screw on the unit cover,
remove the unit cover, then drain (residual) water from the steam tank into an empty bucket via the
manual drain hose (position of the drain hose, see Fig. 2 ).
WARNING!
Danger of burning!
The water in the steam tank can be hot (up to 95 °C). There is danger of burning when
draining the steam tank via the manual drain hose shortly after steam has been produced.
Prevention: wear isolating gloves and be careful when draining the water via the manual drain hose.
