3.4 Functional description

Steam generation
Any time steam is requested, the electrodes are supplied with voltage via
main contactor. 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.
11
Page 12
Upon reaching the requested steam capacity, the inlet valve closes. If the
steam generation decreases below a certain percentage of the required
capacity, due to lowering of the water level (e.g. because of the evaporation process or drainage), the inlet valve opens until the required capacity
is available again.
If the required steam capacity is lower than the actual output, the inlet valve
is closed until the desired capacity is achieved by lowering of the water level
(evaporation process).
Level monitoring
A sensor provided in the steam cylinder cover detects when the water level
gets too high. The moment the sensor comes in contact with water, the
inlet valve closes.
Drainage
As a result of the evaporation process, the conductivity of the water increases
due to an escalating mineral concentration. Eventually, an inadmissibly high
current consumption would take place if this concentration process were
permitted to continue. To prevent this concentration from reaching a value,
unsuitably high for the operation, a certain amount of water is perio dically
drained from the cylinder and replaced by fresh water.
Lime management
The interval controlled SC pump blows air into the steam cylinder. Thus
keeping the solved minerals in the water in motion as a result they are
discharged with the automatic drain cycles.
Control steam production
The steam production is controlled steplessly (continuous control) by the
KTY temperature sensor (for steam bath operation) or by a humidity sensor
(for caldarium operation) and the integrated continuous controller.
Steam bath control
The control of the steam bath components (light, fans, fragrance pumps,
bench heating, etc.) is established via the integrated steam bath board.

Menu Light Stop
The steam generator carries out a system test, during which all three
LED’s light up.
If a failure occurs on the system test, a corresponding error message is
shown in the display.
After the system test the unit is in normal operation mode. The display
shows the standard operating display (rst page of the indication level).
Note: The contents of the standard operating display depends on the actual
operating status and on the conguration of the Nordmann AT4 D and can
differ from the opposite display.
Depending on the selected operating mode of the Nordmann AT4 D, the
steam generator must manually be started via the Start/Stop button of the
display and control unit or via an external Start/Stop button or the operation runs time-controlled via the day timer or the week timer. As soon as
the steam generator is started, the heating current is switched on. The inlet
valve opens (slight delay) and the steam cylinder lls with water. As soon as
the submerged electrodes heat the water up the green LED lights up and
after a few minutes (approx. 5–10 minutes, depending on the conductivity
of the water) steam is produced.
As soon as the set temperature (steam bath operation) or the set humidity
(caldarium operation) in the steam bath cabin is achieved, the light is switched
on and the bath phase starts. During the bath phase the fragrance pump
(if available) is controlled in accordance with the selected operating mode
and the fan (or the ap actuator) is controlled in accordance with the set
temperature or humidity and the actual temperature or the actual humidity
in the steam bath cabin.
14
Page 15
Note: If the Nordmann AT4 D is operated with water of low conductivity it
may happen that the maximum steam capacity is not reached in the rst few
hours of operation. This is normal. As soon as the conductivity has reached
a sufcient level (due to the vaporisation process) the steam generator will
reach the maximum steam capacity.

7.2 Malfunction lists
Important! Most operational malfunctions are not caused by faulty equipment
but rather by improper installation or disregarding of planning guidelines.
Therefore, a complete fault diagnosis always involves a thorough examination of the entire system. Often, the steam hose connection has not been
properly executed, or the fault lies with the humidity control system.

7.3 Notes on fault elimination
For the elimination of faults set the steam generator out of operation as
described in chapter 4.4, separate the unit from the mains and secure
it against inadvertent power-up.
The elimination of faults must be carried out by qualied and well trained
professionals only.
Malfunctions relating to the electrical installation (e.g. replacement of the
backup battery, replacement of fuses) must be repaired by authorized
personnel or by your Nordmann representative’s service technician only.
Automatic standby operation (StandbyDrain, AntiFreeze, KeepWarm) of steam
cylinder active or failed.
DANGER!
Danger of electric hazard!
Warning status: No measures must be taken.
Error status: Check water supply, heating
voltage supply, main contactor.
Repair work and the replacement of faulty components must be carried out
by your Nordmann representative’s service technician only!
7.4 Resetting the error indication (red LED lights)
To reset the error indication:
Disconnect the steam generator from the mains. Wait approx. 5 seconds, then reconnect the unit to the mains.
Note: If the fault has not been eliminated, the error indication reappears
after a short while.

7.5 Replacing the backup battery on the control board
1. Set the Nordmann AT4 D out of operation as described in chapter
4.4, disconnect it from the mains and secure the unit against inadvertent power-up.
2. Undo the screw of the front cover of the control compartment, then
remove the front cover.
CAUTION!
The electronic components inside the steam generator are very
sensitive to electrostatic discharge. Before carrying out the next
step, appropriate measures must be taken to protect the electronic
components against damage caused by electrostatic discharge
(ESD protection).
3. Carefully lift-off the display and control unit from the housing frame,
swivel it 90° to the left, then x it to the unit frame again.
4. Undo the fastening screws of the control board, then carefully pull-off
the control board from the control unit assembly.
5. Replace the backup battery (CR2032, Lithium 3V).
6. Reassemble the unit in reverse order.
7. If necessary set date and time (see chapter 5.3.8 and 5.3.9).
WARNING!
Environmental hazard!
The old battery must be returned to an authorised collecting
point for correct disposal/recycling in accordance with local
regulations. In no case the old battery must be disposed of
in the domestic waste or into the environment.
