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).
Fig. 13 Functional principle of the cooling process
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.
