Operating manual
1.The dehumidifier is designed for 1/N/PEN 230V/ 50Hz
single-phase current with earth connector. 16Afuse.
2.If cable drums etc. are used, they always have to be
completely unrolled during operation! When connecting several
dehumidifiers to a cable drum, always observe total power and
fusing specifications!
3.Socket CEE 7/7:
The dehumidifier must only be operated with ground
connection!
4. The device must be positioned in a way that the air inlet and
outlet grids are not being blocked.
5. The condensate can be permanently discharged from the
dehumidifier via the hose connection. To do so, the condensate
discharge line must be laid with a continuous decline all the
way to the drain.
Alternatively, you can set up a water collection container next
to the device. Due to the high dehumidification performance,
we recommend using a container with a volume of at
least90litres. Once the water collection container is full, the
dehumidifier does not switch off automatically. For this reason,
always make sure to empty the container in time.
To do so, the condensate discharge line must be laid with a
continuous decline all the way to the drain.
If you use a separate water collection container, cut the
condensation drain hose connected to the dehumidifier right
below the upper part of the container (or above the maximum
water level inside the container). If the hose end is positioned
below the water level in the collection container, it may affect
the condensate discharging properly from the dehumidifier,
which will lead to water leaking out uncontrollably from the
dehumidifier.
See operating manual when operating with integrated
condensate pump.
6. Room temperatures below approx.18°C may cause the
(extensive) formation of ice at the dehumidifier's cooling
element(air intake side). The ice will quickly defrost
automatically and regularly. The fan in the dehumidifier
switches off during the defrosting process. The defrosting time
depends on the temperature.
7. After switching the dehumidifier off, wait at least5minutes
until switching it on again. Otherwise damages on the device
may occur.
8. Cleaning: In order to guarantee a high dehumidification
performance, clean the device regularly. Always disconnect the
mains plug prior to cleaning! Clean the cooling grids of the
dehumidifier's air inlet every4-6weeks depending on their
degree of contamination (see instructions).
EN 5
dehumidifier TTK 400
The connection of the condensate discharge and the attached
condensation hose should be disconnected after each use. In
addition, they should be cleaned with compressed air in the
opposite direction of the water current direction. Otherwise,
contaminations and blockage may occur inside the condensate
discharge line, and water may uncontrollably leak out of the
lower part of the dehumidifier.
It is best to use air filters which also have to be cleaned with
compressed air and/or water on a regular basis, depending on
their degree of contamination.
Transport and storage
The device can be transported and stored in vertical and
horizontal position. Operation must only be carried out in a
vertical position! Other operating positions will lead to a
complete device failure!
Note1 for operation: Optimal room temperatures
At room temperatures below12°C, the room should be heated
in order to optimise energy efficiency and to reduce drying
periods. For this purpose, preferably use an electric heater. Do
not under any circumstances use direct oil or gas heaters
(devices without flue pipe connection) as these release large
amounts of water vapour into the room air. This will extremely
extend the drying periods and increase energy costs. The ideal
operating temperature for efficient drying is between15–
25°C. In order to carry out a proper dehumidification process
and to optimise flowrates, position the electric heater as far
away from the dryer as possible.
Note2 for operation: Air distribution with fans
If the areas to be dehumidified are in several different rooms,
we recommend using one fan per room in rooms where no
dehumidifier has been set up. This will significantly reduce the
drying period. Always keep the doors between the individual
rooms open. Otherwise, a dehumidifier has to be installed in
each room. All windows and exterior doors must to be shut
during the drying process!

Information about the device
Description of the device
The device uses the principle of condensation to automatically
dehumidify rooms.
The fan sucks damp room air through the air inlet, the air filter,
the evaporator and to the condenser located behind it. The air is
cooled at the cold evaporator until it is below the dew point.
Water vapour contained in the room air precipitates on the
evaporator fins as condensation or rime. The dehumidified,
cooled air is slightly warmed at the condenser and blown out
again. The drier air thus conditioned mixes with the air in the
room. The humidity in the room where the device is positioned
is reduced as air constantly circulates through the device.
The condensate is discharged through a pressure-resistant pipe
connection by means of a condensation drain hose. For the
collection you can for instance place a sufficiently dimensioned
collection container beside the construction dryer.
Optionally, the condensed water can also be discharged from
the device by means of a retrofitted condensate pump (see
chapter Installing the condensate pump).
For easy operation and transport, the device is fitted with an
on/ off switch, an operating hours counter, a transport handle
and wheels. Two feet with rubber buffers prevent the device
from rolling away.
The device can reduce the relative humidity of a room to approx.
35%.
Because of the heat radiation generated during operation, the
room temperature may rise slightly.

Switching the device on
Once you have completely installed the device as described in
the Start-up chapter, you can switch it on.
1. Make sure that the condensation drain hose has been
properly laid and connected. Do not create tripping
hazards.
2. Make sure that the condensation drain hose is neither
kinked nor jammed and that there are no objects on the
condensation drain hose.
3. Make sure that the condensate can run off properly.
4. Turn the on/ off switch(4) to the ONposition(17).
ðThe device is switched on.
ðThe compressor always starts with a delay of approx. 7s.
ðThe fan starts approx.10s after that.
Continuous operation mode
In continuous operation mode, the device dehumidifies the air
constantly, regardless of the humidity.
Hygrostat operation mode (optional)
The device can also be operated with a hygrostat. The hygrostat
switches the device on or off depending on the relative
humidity.
If you choose to operate the device with an optional hygrostat,
set the desired relative humidity at the hygrostat (see
instructions of the optional hygrostat).
In doing so, observe the switching point. Provided the external
hygrostat activates the compressor via the set humidity value,
then hygrostat and drying unit operate correctly. You can tell the
incorrect operation of the external hygrostat if the compressor of
the device operates below the set value and switches off above
it. In this case you need to open the hygrostat and reconnect the
connections.
Automatic defrost
At low ambient temperatures, ice may form at the evaporator
during dehumidification. The device will then carry out an
automatic defrost. Dehumidification is briefly interrupted during
defrosting. The fan keeps running.
The duration of the defrost process can vary. Do not switch off
the device during automatic defrost. Do not remove the mains
plug from the mains socket.
