Operating manual – dehumidifier TTK 28 E
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 in case the condensation tank is not installed
correctly, the condensation tank indicator light (see chapter
Operating elements) on the control panel is illuminated. 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 at the condensation connection.
The device can reduce the relative humidity of a room to approx.
40%.
In addition, the device may also be used as a kind of clothes
dryer to dry wet laundry in living and working spaces.
Because of the heat radiation generated during operation, the
room temperature may rise slightly.

Transport and storage
Notice
If you store or transport the device improperly, the
device may be damaged.
Note the information regarding transport and storage of
the device.
Transport
Before transporting the device, proceed as follows:
• Switch off the device.
• Hold onto the mains plug while pulling the power cable out
of the mains socket.
• Drain the remaining condensate from the device and the
condensation drain hose (see chapter Maintenance).
• To make the device easier to transport, it is fitted with
wheels.
• Do not use the power cable to drag the device.
• Only wheel the device on a level and smooth surface.
After transporting the device, observe the following:
• Set up the device in an upright position after transport.
• Leave the device to rest for 12-24hours, so the
refrigerant can accumulate within the compressor. Wait
12-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.
Storage
Before storing the device, proceed as follows:
• Drain the remaining condensate from the device and the
condensation drain hose (see chapter Maintenance).
• Empty and clean the condensation tank prior to storage.
When the device is not being used, observe the following
storage conditions:
• dry and protected from frost and heat
• in an upright position where it is protected from dust and
direct sunlight
• with a cover to protect it from invasive dust if necessary
• Place no further devices or objects on top of the device to
prevent it from being damaged.

flashes (see chapter Error codes).
• Wait for 10minutes before restarting the device. If the
device is not starting, have the electrics checked by a
specialist company or by Trotec.
The device is running, but there is no formation of
condensate:
• Check the float in the condensation tank for dirt. If
necessary, clean the condensation tank. The float must be
able to move freely.
• Check the room temperature. Observe the device's
permissible operating range according to the technical
data. Possibly, the device does not start because the
ambient temperature is too low (< 5 °C).
• Ensure that the relative room humidity complies with the
technical data.
• Check the preselected desired room humidity level. The
relative humidity in the room must be above the selected
range. If necessary, reduce the preselected desired room
humidity.
• Check the air filter for dirt. If necessary, clean or replace
the air filter.
• From the outside, check the condenser for dirt (see
chapter Maintenance). If the condenser is dirty, have it
cleaned by a specialist company or by Trotec.
• The device might carry out an automatic defrost. During
automatic defrost, the device does not dehumidify.
The device is loud or vibrates:
• Check whether the device is set up in a stable and upright
position.
Condensate is leaking:
• Check the device for leaks.

Activities required before starting maintenance
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
• Switch off the device.
• 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.
Cleaning the housing
Clean the device 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.
