3.4 Functional description
The Nordmann Omega steam generator is an atmospheric steam generator. It operates on the resistance
heating principle and is designed for steam generation for steam baths or steam showers.
Water supply
The water is supplied via a lter valve (accessory "Z261") to the steam generator. It reaches the steam
tank via the level controlled inlet valve and the open lling cup.
Note: The open lling cup is designed in such a way, that the supply water is separated from the unit
water. That means, that no unit water can ow back into the supply water line.
Level regulation
The water level in the steam tank is continuously monitored with the level unit. If the water level reaches
a preset level (due to the evaporation process) the level unit supplies a signal to the controller. This
opens the inlet valve and the steam tank is lled up. When the preset operating level is reached, the
level unit supplies another signal to the controller to close the inlet valve.
The pressure equalizing pipe connected to steam tank and the level unit ensures that the water levels
are the same in the steam tank and the level unit.
Steam generation regulation
The steam is produced in the steam tank by one or several resistance heating elements. The integrated
continuous controller or an external controller control the steam production in steps from 0 to 100 %.
Alternatively the Nordmann Omega can be controlled also via an On/Off controller.
Flushing
The evaporation process increases the concentration of minerals in the water of the steam tank.Asuitable
volume of water must be ushed out of the steam tank from time to time and replaced by fresh water to
ensure that this concentration does not exceed a specic value unsuitable for operation.
The Nordmann Omega consists of the following two forms of ushing:
– Automatic ushing takes place as soon as the water in the steam tank exceeds the upper operat-
ing level (e.g. by foaming of the water).
– Flushing dependent on water quality.
Automatic or water quality dependent ushing takes place depending on the water quality and the op-
erating data. If the lowest operating level is reached during the ushing process, the inlet valve remains
open until the water level in the steam tank has reached the normal working level again. If the lowest
operating level is not reached, the inlet valve is closed.

DANGER!
Risk of electric shock!
After switching off the unit switch, there is still live voltage inside the control compartment of the Nord-
mann Omega.Therefore, before opening the unit the steam generator must be always separated
from the mains supply via the electrical isolator.

17
4.3 Commissioning after an interruption of operation
The following description outlines the start up procedure after an interruption of operation (e.g. after
servicing the steam generator). It is assumed that rst-time commissioning has been carried out prop-
erly by the service technician of your Nordmann representative and the Nordmann Omega has been
congured accordingly.
1. When putting the steam generator into operation after work has been carried out on the steam sys-
tem, the operating personnel must check whether the steam pipe is open over the entire length.
WARNING!
Danger of scalding!
A steam line that is reduced in cross section or completely closed will cause an excessive
increase in pressure in the steam tank when the unit is operating and could lead to the risk
of scalding accidents!
2. Examine the steam generator and installation for possible damage.
DANGER!
A damaged unit or systems with damaged installations may present danger to human life
or cause severe damage to material assets.
Therefore: Damaged systems and/or systems with damaged or faulty installations must not be
operated.
3. Relocate the unit cover and lock it with the retaining screw.
4. Open the lter valve / shut-off valve in the water supply line.
5. Switch on the electrical isolator in the mains supply.
6. Switch on the unit switch of the steam generator.
The Nordmann Omega carries out an automatic system test (initialising). If a malfunction is detected
during the system test, the status LED indicates a "Warning" (LED lights yellow) or "Fault" (LED
lights red).
If the is successful, the steam tank lls up and a function check on the level unit is carried out.
Note: If a malfunction is detected during the function check on the level unit, the status LED indicates
a "Warning" (LED light yellow) or "Fault" (LED light red).
If the function check on the level unit is successful, the Nordmann Omega will be in normal operat-
ing mode and the LED blinks green. As soon as a steam demand is present or the steam opera-
tion is started manually, the heating current is switched on, the status LED lights green and steam
is produced after a short time.

18
4.4 Notes on operation
After 24 hours in standby operation (no humidity demand), the steam tank is emptied automatically. The
steam tank remains empty and is not lled until a steam demand is present or the steam operation is
started manually.
If, during operation, it is recognized that consistently foaming occurs in the steam tank, the carbonate
hardness setting of the inlet water should be increased. As a result, the steam tank of the Nordmann
Omega is drained more frequently and thus the foam formation is counteracted.
4.5 Inspections during operation
During operation the Nordmann Omega and the humidication system have to be inspected weekly. On
this occasion check the following:
• the water and steam installations for any leaks.
• the steam generator and the other system components for correct xing and any damage.
• the electric installation for any damage.
If the inspection reveals any irregularities (e.g. leakages, error indication) or any damaged components
take the Nordmann Omega out of operation as described in chapter4.6. Then, contact your Nordmann
representative.

19
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 in the mains sup-
ply line and secure switch 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.

20
5 Working with the integrated web interface
5.1 General information about the web interface
The Nordmann Omega is equipped with an integrated web interface. This enables you to congure the
Nordmann Omega and to query unit settings via a web browser which is running on a Laptop connected
to the Nordmann Omega via an Ethernet cable.
Note: The standard version of the Nordmann Omega has no touch-screen and can only be congured
via the integrated web interface.
CAUTION!
The Ethernet interface of the Nordmann Omega is designed for a point-to-point connection with
a laptop and has no security functions. The permanent connection of the Nordmann Omega
via the Ethernet interface to a local or public network is, due to the lack of security functions,
not recommended.
The integrated web interface supports IPv4 and DHCP. By default, the DHCP mode is activated. There-
fore, a DHCP server must be present in the network in order to enable a connection setup. If no DHCP
server is available, the Nordmann Omega automatically switches to "autoIP" after 60 seconds. In this
case, an IP address between 169.254.1.0 to 169.254.254.255 is selected, whereby the subnet mask is
set to 255.255.0.0.
By entering the URL "http://Hostname/index.htm" in the input line of the web browser the website of
the Nordmann Omega is called up.
The host name is composed of "Host Name Prex" + "Host Name Sufx". The "Host Name Prex"
is set xed to "SPA" and can not be changed. Ex factory the "Hostname sufx" is set to "1". Thus the
factory setting for the host name is "SPA1".
Note: The "Host Name Sufx" as well as all other IP settings for the connection can be set under "Engi-
neering> Communication > IP Settings" on the website of the integrated web interface.
5.2 Connect the laptop and start the web interface
To connect the laptop, proceed as follows:
1. Switch off the Nordmann Omega via the unit switch. Switch off the electrical isolator in the mains
supply line and secure switch in "Off" position against accidentally being switched on.
2. Loosen the retaining screw of the unit cover, then remove the unit cover.
3. Remove the closure cap from the corresponding housing feed-through at the bottom of the Nordmann
Omega housing in order to feed the Ethernet cable into the housing.
Note: at the rst time, one of the pre-punched feed-through holes must be punched out. Later, this
opening is to be closed with a appropriate closure cap.
4. Feed an Ethernet cable through the housing feed-through into the Nordmann Omega and connect
it to the RJ45 port on the control board of the Nordmann Omega and to the RJ45 port of the laptop.
