• Only install the device in compliance with the national

installation regulations.

• Please observe the local regulations.

• Observe the national gas regulations.

• Only install, operate and store the device TTK 90 E in a

room measuring more than 4m2.

• Store the device in a way that no mechanical damage can

occur.

• Please note that the connected pipelines must not contain

any sources of ignition.

• R290 is a refrigerant that complies with European

environmental regulations. No part of the cooling circuit

may be perforated.

• Observe the maximum refrigerant capacity in the technical

data.

• Do not drill through or burn.

• Do not use any means other than those recommended by

the manufacturer for accelerating the defrosting process.

• Every person working with or at the refrigerant circuit must

be able to provide a certificate of qualification issued by a

body accredited by the industry, demonstrating their

competence in the safe use of refrigerants based on a

procedure well-known in the industry.

Information about the device

Device description

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

Operation) 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. 30 %.

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.

Errors and faults

The device has been checked for proper functioning several

times during production. If malfunctions occur nonetheless,

check the device according to the following list.

The device does not start:

• Check the power connection.

• Check the power cable and mains plug for damage.

• Check the on-site fusing.

• Check the filling level of the condensation tank and empty

it if necessary. The condensation tank full LED(9) must not

light up.

• Check the condensation tank for correct seating.

• Check the room temperature and the current room

humidity level. If the current room humidity level is below

the room humidity level set, the device will not switch on.

Observe the device's permissible operating range

according to the technical data.

• 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 and the current room

humidity level. If the current room humidity level is below

the room humidity level set, the device will not switch on.

Observe the device's permissible operating range

according to the technical data.

• Ensure that the relative room humidity complies with the

technical data.

• Check the preselected relative room humidity. The

humidity in the room must be above the selected range.

• Check whether the device is running in comfort mode. In

this case, the compressor switches off automatically once

the relative room humidity is below 45%.

• 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.

The compressor does not start:

• Check the room temperature and the current room

humidity level. If the current room humidity level is below

the room humidity level set, the device will not switch on.

Observe the device's permissible operating range

according to the technical data.

• Ensure that the relative room humidity complies with the

technical data.

• Check the preselected relative room humidity. The

humidity in the room must be above the selected range.

• Check whether the device is running in comfort mode. In

this case, the compressor switches off automatically once

the relative room humidity is below 45%.

• Check whether the overheating protection of the

compressor has tripped. Disconnect the device from the

mains and let it cool down for approx. 10minutes before

reconnecting it.

• The device might carry out an automatic defrost. During

automatic defrost, the device does not dehumidify.

The device gets very warm, is loud or is losing

performance:

• Check the air inlets and air filters for dirt. Remove external

dirt.

• From the outside, check the device for dirt (see chapter

Maintenance). If the inside of the device is dirty, have it

cleaned by a specialist company for cooling and

air-conditioning or by Trotec.

Note

Wait for at least 10minutes after maintenance and

repair work. Only then switch the device back on.

The device still does not operate correctly after these

checks:

Please contact the customer service. If necessary, bring the

device to a specialist company for cooling and air-conditioning

or to Trotec for repair.
