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 into the condensation tray

continuously or only during the defrost phases. The

condensation is fed through a pressure-resistant pipe

connection and out of the device by a condensate pump.

To do so, a condensation drain hose is connected to the hose

connector of the device and the condensate is drained.

The device has a control panel for operating and controlling the

functions.

The device comes with a hot gas automatic defrost system.

Here, the hot gas of the refrigerant circuit is used actively for

fast and effective defrosting. This makes the device operate

effectively even at temperatures below 15°C.

Because of the heat radiation generated during operation, the

room temperature may rise slightly.

Note

The condensate pump is fitted with a float switch.

It completely switches off the condenser dryer when a

critical filling level is reached in the condensation tray.

Additionally, an acoustic signal will be emitted and the

condensation tray indicator light is illuminated. After

troubleshooting, the condenser dryer must be switched

back on by hand.

Transport and storage

Note

If you store or transport the device improperly, the

device may be damaged.

Note the information regarding transport and storage of

the device.

Transport

To make the device easier to transport, it is fitted with wheels.

Always utilize the help of another person to transport the device.

Do not try to transport the device without the help of another

person. To lift the device, use a forklift or an elevating truck as

appropriate.

Before transporting the device, observe the following:

• Wait until the condensate pump stops pumping

condensate.

• Switch off the device.

• Hold onto the mains plug while pulling the power cable out

of the mains socket.

• Do not use the power cable to drag the device.

• Drain the remaining condensate from the device and the

condensation drain hose (see chapter Maintenance).

• Remove the condensation drain hose.

• 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.

• After having transported the device in horizontal position,

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. Any warranty claims will be voided

in this case.

Storage

Before storing the device, proceed as follows:

• Drain the remaining condensate from the device and the

condensation drain hose (see chapter Maintenance).

• Hold onto the mains plug while pulling the power cable out

of the mains socket.

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.

• 1x Manual

Unpacking the device

1. Open the cardboard box and take the device out.

2. Completely remove the packaging.

3. Fully unwind the power cable. Make sure that the power

cable is not damaged and that you do not damage it during

unwinding.

Start-up

When positioning the device, observe the minimum distance

from walls or other objects as described in the Technical data

chapter.

• Before restarting the device, check the condition of the

power cable. If there are doubts as to the sound condition,

contact the customer service.

• Set the device up in an upright and stable position.

• Do not create tripping hazards when laying the power

cable or other electric cables, especially when positioning

the device in the middle of the room. Use cable bridges.

• Make sure that extension cables are completely unrolled.

• When positioning the device, keep a sufficient distance to

heat sources.

• Make sure that no curtains or other objects interfere with

the air flow.

• When positioning the device, particularly in wet areas,

secure it locally with an RCD (residual current device)

which complies with the respective regulations.

Inserting the air filter

Note

Do not operate the device without an inserted air filter!

Without the air filter, the inside of the device will be

heavily contaminated. This could reduce the

performance and result in damage to the device.

• Make sure that both air filters are installed before

switching the device on.

Positioning the condensation drain hose

üA suitable hose (diameter: 8mm) is ready for use.

üThe device is switched off.

1. Connect the condensation drain hose to the condensation

hose connection(7) at the device.

2. Make sure that the condensation drain hose is properly

connected to the device and free of damage.
