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.
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 tank is not installed correctly, the condensation
tank indicator light on the control panel will be illuminated and
an error code will be displayed as well (see chapter Operating
elements). The device switches off. The indications only
disappear once the emptied condensation tank is reinserted.
Optionally, the condensed water can be drained by attaching a
hose at the condensation connection.
The device can reduce the relative humidity of a room to approx.
35%.
In addition, the device may also be used as a kind of clothes
dryer to dry wet laundry in living or working spaces.
Because of the heat radiation generated during operation, the
room temperature may rise slightly.

Activities required before starting maintenance
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
• Switch the device off.
• Hold onto the mains plug while pulling the power cable out
of the mains socket.
Warning of electrical voltage
Tasks which require the housing to be opened
must only be carried out by authorised specialist
companies or by Trotec.
Refrigerant circuit
Danger
Natural refrigerant propane (R290)!
H220 – Extremely flammable gas.
H280 – Contains gas under pressure; may explode if
heated.
P210 – Keep away from heat, sparks, open flames and
other ignition sources. No smoking.
P377 – Leaking gas fire: Do not extinguish, unless leak
can be stopped safely.
P410+P403 – Protect from sunlight. Store in a well-
ventilated place.
• The entire refrigerant circuit is a maintenance-free,
hermetically sealed system and may only be maintained or
repaired by specialist companies for cooling and air-
conditioning or by Trotec.
Safety signs and labels on the device
Check the safety signs and labels attached to the device at
regular intervals. Replace illegible safety signs!
Cleaning the housing
Clean the housing with a soft, damp and lint-free cloth. Ensure
that no moisture enters the housing. Protect electrical
components from moisture. Do not use any aggressive cleaning
agents such as cleaning sprays, solvents, alcohol-based or
abrasive cleaners to dampen the cloth.
Visual inspection of the inside of the device for dirt
1. Remove the air filter.
2. Use a torch to illuminate the openings of the device.
3. Check the inside of the device for dirt.
4. If you see a thick layer of dust, have the inside of the
device cleaned by a specialist company for cooling and air-
conditioning or by Trotec.
5. Put the air filter back in.
Cleaning the air filter
Note
Ensure that the air filter is not worn or damaged. The
corners and edges of the air filter must not be
deformed or rounded. Before reinserting the air filter,
make sure that it is undamaged and dry!
The air filter has to be cleaned as soon as it is dirty. This is
brought to light e.g. by a reduced capacity (see chapter Errors
and faults).
1. Remove the air filter from the device.

EN 15
dehumidifier TTK 54 E / TTK 66 E
2. Clean the filter using a slightly damp, soft, lint-free cloth. If
the filter is heavily contaminated, clean it with warm water
mixed with a neutral cleaning agent.
3. Allow the filter to dry completely. Do not insert a wet filter
into the device!
4. Reinsert the air filter into the device.
Emptying the condensation tank
If the condensation tank is full or not inserted correctly, an
acoustic signal will be emitted. Moreover, the Full LED(12) will
be lit and error codeP2 indicated on the segment display(20).
The compressor and fan will switch off.
1. Take the condensation tank out of the device.

Activities required after maintenance
If you want to continue using the device:
• Leave the device to rest for 12to24hours, so the
refrigerant can accumulate within the compressor. Wait
12to24hours before switching the device back on! Acting
contrary might lead to compressor damage and a
malfunctioning device. If so, any warranty claims will be
voided.
• Reconnect the device to the mains.
If you do not intend to use the device for a considerable time:
• Store the device according to the Storage chapter.
