Condenser

Functional principle of

the cooling process

The air conditioner

cools the air by re-

moving heat from it.

The fan (circulation

air) conducts cooled

air into the room. The

heat that the device

has removed from the

air is conducted out-

side via the air outlet

hose.

Humidity is removed

from the air and drips

as condensate from the

evaporator onto the hot

condenser and evapora-

tes. Excess condensate

drips from the condenser

into a collection tray

and conducted from

there to the condenser

again using a rotor,

evaporated, and then

conducted away with

the exhaust air ow.

Fig. 14

upwards from the machine

Removing the air lter

With low cleaning effort, you

can guarantee malfunction-free

operation and a long service

life.

■ Use only mild, environment-

friendly cleaning agents.

■ Regularly clean the

ventilation slots.

■ Clean the device as required,

but at least once a year, with

a moist cloth and lukewarm

water.

■ Do not expose the device to

direct water spray.

CAUTION

Always turn off the device and pull the mains plug before cleaning!

Cleaning the air ﬁlter

Clean the air ﬁlter regularly,

but at least every 100 operat-

ing hours. In case of strongly

contaminated air, the period is

reduced accordingly.

1. Switch off the device and

pull the mains plug.

2. Remove the ﬁlter from the

device (Fig. 14).

3. Clean the ﬁlter using a

vacuum cleaner or, in case

of heavy soiling, carefully

using lukewarm water (Fig.

15/16).

4. Let the ﬁlter air-dry and then

reinsert it.

Draining the condensate

■ The condensate evaporates

during operation and is then

conducted outside with the

exhaust air via the air outlet

hose.

■ In case of extreme humidity,

the device collects conden-

sate in a reservoir. If the

permissible level is exceeded,

the red fault LED lights up

and the device shuts down.

■ The reservoir must be

emptied via the condensate

drain spout (Fig. 17).

Never operate the device without the air lter.
