The following safety signs and labels are attached to the device:

The following label is attached to the device in German, English

and French.

Operating manual

1.The dehumidifier is designed for 1/N/PEN 230V/ 50Hz

single-phase current with earth connector. 16Afuse.

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

least90litres. 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 least5minutes

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 every4-6weeks 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!

Note1 for operation: Optimal room temperatures

At room temperatures below12°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 between15–

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.

Note2 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.
