Description of the device
The device TTK 68 E / TTK 69 E 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 either condensation or rime. The
dehumidified, cooled air is slightly warmed 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.
Depending on the air temperature and the relative humidity, the
condensed water either drops continuously or only during the
defrost phase through the integrated drain nozzle into the
condensation tank below. It is fitted with a float to measure the
filling level.
The device has a control panel for operating and controlling the
functions.
Once the maximum filling level of the condensation tank is
reached or if the condensation tank is not installed correctly, the
condensation tank indicator light (see chapter Operating
elements) on the control panel will be illuminated immediately.
The device switches off. The condensation tank indicator light
only goes out again once the emptied condensation tank is
reinserted.
Optionally, the condensed water can be drained by attaching a
hose (Ø = 14mm) at the condensation connection.
The device can reduce the relative humidity of a room to approx.
30 %.
Because of the heat radiation generated during operation, the
room temperature may rise slightly.

section of the device inwards.
2. Carefully pull the front part off at the bottom and remove it
by pushing it upwards
6. Reinsert the filter and push the air filter down until it clicks
into place.
7. Reattach the housing's front section.
8. To carry out a filter reset, press the buttons Fan(21) and
Humidity(19) simultaneously.
ð The Filter Clean indication(15) disappears.
Emptying the condensation tank
Once the condensation tank is full, the device stops the
dehumidification operation and switches itself off. The WaterFullindication (14) is illuminated.
1. Take the condensation tank out of the device.
3. Pull the fastenings of the air filter outwards to remove the
filter.
4. Clean the filter by means of a soft, lint-free, slightly
moistened cloth. Should the filter be heavily soiled, clean it
using warm water and a neutral detergent.
