Device setup/installation
The device may be installed only in
frost-free, dry rooms. The room tem-
perature must lie between +5 °C and a
maximum of +40 °C.
Ventilation and air conditioning system
air lines that are not installed in heated
areas must be designed with suitable
heat insulation (danger when the dew
point temperature is undershot) to pre-
vent the formation of condensation.
For components or windows with bad
heat insulation properties, in case
of missing construction, and in old
buildings, condensation may form on
window glass at cold temperatures and
in case of increased air humidity in living
areas. The surface temperature of the
components must lie above the dew
point temperature of the indoor air (at
least about +15 °C).
In normal operation, germs or mould
cannot form inside the device unit since
the humidification water is continuously
treated and disinfected during operation.
Mounting
The device is intended for horizontal
mounting. It may deviate a maximum of
+/-1° from the horizontal position and
must be mounted to a massive wall that
can bear the load. The intrinsic opera-
ting weight of the air humidification unit
must be taken into consideration for the
suspension. No shocks or jolts may af-
fect the device. For mounting and setup,
the national and local regulations must
be observed. The device may be installed
only in compliance with the national
installation regulations.
Electrical connection
The electrical connection of the
supply and sensor line should
be performed by an electrician accor-
ding to the local regulations. Before the
device is opened, the voltage supply
must be shut o at all poles and secu-
red against reactivation. If the mains
connecting line of the device is dama-
ged or defective, it must be repaired or
replaced immediately to prevent risks.
This work may be performed only by
authorised expert personnel.
Water connections
The water, heating, and waste water
connections must be established by an
expert. For the connection to the water
supply, only the original connecting
hoses provided in delivery may be used.
Pay attention to the seal tightness of the
lines. The maximum water pressure of
the mains water supply of 0.7 MPa and
of the water heater battery of 1 MPa may
not be exceeded.
Water quality
Only mains water that corresponds with
the local mains water ordinance may
be used for the water supply. The water
inlet pipe to the air humidification unit
should be established using optionally
available connection sets.
In case of a chlorine content over 0.1
mg/l, the standard water filter (5 μm)
must be replaced by a dual filter (5 μm/
carbon). If the iron content of the mains
water exceeds a value of 0.1 mg/l, an
iron filter should also be built into the
water inlet pipe.
The device can be used for a maximum
hardness of water of 26° dH. When this
value is exceeded, the service life of the
reverse osmosis membrane is conside-
rably reduced.
Operation of the device
Every working method that impairs the
safety of the device is prohibited. All
warning and safety devices should be
regularly checked for proper function.
Safety devices may not be disassembled
or decommissioned.
Mounting, disassembly, maintenance,
and servicing of the device

7. Description of functions
7.1 WORKING PRINCIPLE The air humidification unit works
according to the principle of natural
evaporation and guarantees a constant
relative air humidity that can be adjusted
between 40 % and 60 % in the supply air.
The unit works automatically, and the air
humidity is electronically monitored in
the device. The indoor air can thus not
be overhumidified.
The air humidification unit is dimensi-
oned for a maximum operating air
volume flow of 250 m³/h (LBE 250) /
500 m³/h (LBE 500). The water tank is
supplied with mains water from the
mains water supply. According to the
evaporative power, a maximum of 2.5
litres of water, which is continuously
placed, is located in the tank. The
maximum filling level is limited using a
floating switch and mechanical overflow.
The water in the tank is continuously
disinfected using UVC light, whereby the
UVC pipe illuminates the complete water
tank and evaporation surface. The UVC
pipe has a radiant power of 4.3 watt at a
wavelength of 253.7 nm.
For safety reasons, the UVC pipe is
monitored by UV diode. This monitoring
process can detect a failure, soiling, or
line breakage of the disinfection unit. If
the radiant power is too low, the water is
drained and a error message is output.
The unit is automatically shut down in
case the UVC pipe malfunctions. To
prevent deposits during operation,
especially scale deposits on the bladed
rotary evaporator and the water tank,
the standard version of the air humidifi-
cation unit is equipped with a reverse
osmosis unit. In the standard design, the
reverse osmosis unit is integrated into
the water inlet pipe between the
solenoid valve and the water tank.
A prefiltering unit for the water supply,
which should be installed during the
course of mounting, is included in the
scope of supply. As an additional safety
measure, the water is drained and an
error message output in case of the air
humidity is exceeded by more than 25 %
of the reference value of the water for
longer tan 25 hours.

OPERATING AND INSTALLATION INSTRUCTIONS LBE 250 / LBE 500 PAGE 11
The air humidity is controlled using the
water moistened surface of the bladed
rotor and the water level in the tank. As
the water level rises, the rotor blades
are submerged more deeply into the
water, increasing the surface area of the
blades that becomes wet.
The passing air flow absorbs moisture
from the wet blades, in accordance with
a specific reference value that is set as a
constant. However, as a rule the set rela-
tive humidity is converted to the relevant
absolute humidity at 21 °C (factory
setting) and then controlled.

OPERATING AND INSTALLATION INSTRUCTIONS LBE 250 / LBE 500 PAGE 17
• After all complete connections have been established
(ventilation, water, and electrical), the air humidification unit
can be commissioned.
The device may be commissioned only by qualified
experts. The commissioning program must be
completely completed to start the device.
After the mains plug is plugged in, the following appears on
the display:
• The supply water should be tested using the test strip
included in the delivery (immerse the test strip in water,
shake the strip, and check the colour after one minute). The
hardness of water (°dH) determined in this manner should
be entered according to the table.
• After the hardness of water is set, the following appears:
„UV Calibration <On/O“.
• „On“ starts the UV calibration (the program runs for about
three minutes).
• In the case of the UVC calibration, the light output of the UVC
pipe is determined and saved as a calibrated value
(= reference value of the new pipe).
• When the program is needed, the following appears in the
display for 8 seconds. Display: (see the picture opposite).
• After that, the air humidification unit automatically switches
to operating mode.

UVC pipe or
sensor defective!
After the commissioning of the device,
the function and operation should be
observed for about 15 minutes. If leaks
are found on the water or air side or if
disturbing noises are noticed, shut down
the device immediately. In this case,
have the determined faults remedied
immediately under observance of the sa-
fety regulations. If something is not clear
or if you have questions, contact the
expert/Service department or manufac-
turer immediately.
After commissioning, the
current supply may not be
interrupted for longer than one
day so that the hygienic requirements
can be observed.
In case of an interruption in the elec-
trical voltage supply of more than 24
hours, the air humidification unit may
become contaminated with germs. In
this case, a general cleaning (a cleaning
agent on an organic basis) of all com-
ponents should be performed before
the unit is commissioned. If necessary,
components must be replaced.

• This shows whether the air temperature is controlled via
the internal or external sensor.
• In the case of the Int. Sensor display, the outlet air tem-
perature of the air humidification unit is constantly regu-
lated to the reference value set in the customer menu.
• In the case of the Ext. Sensor display, the outlet air tem-
perature is regulated depending on the external tempe-
rature sensor.
• According to the mounting site of the temperature sen-
sor (in the extract air line in case of air heating or after
the second air heater battery in case of low-temperature
heating), the device regulates the temperature to the
temperature reference value. The air outlet temperature
of the air humidification unit is limited to a minimum of
+16°C and a maximum of +35°C by the software.
• Set the existing hardness of water.
(See Chapter 12 Commissioning.)
• The UV Calibration must always be performed when the
UVC pipe is exchanged.
(See Chapter 12 Commissioning.)
• Using Control by <, the parallel control between the ven-
tilation device and the air humidification unit can be se-
lected.
• In the case of the Switch Input presetting, a control
cable must be connected from the ventilation device to
the input of the air humidification unit. This cable ma-
kes contact whilst the ventilation device is running and
breaks contact when it is shut down.
• In the case of the Air Current Measurement selection,
the operational status of the ventilation device is auto-
matically determined using the installed microphone
and the air humidification unit is actuated synchronously
(factory setting).
• The Elect. Heating parameter shows the operational sta-
tus for the activated heater battery.
• When Elect. Heating Act. < is set, the control system is
programmed for the actuation of an electric heater bat-
tery.
• When Elect. Heating Deact. < is set, the control system
is programmed for the actuation of a water heater bat-
tery.
