function, follow the procedure above
until you hear three short beeps from
the unit.
Emergency button
If the remote control does not work or
needs maintenance:
Open and lift the front panel at an an-
gle where you can reach the emergen-
cy button.
1.Pushing the emergency button once
(one beep) results in forced COOL-
ING
2.Two presses of the emergency but-
ton within 3 seconds (two beeps)
result in forced HEATING.
3.To switch off the unit, simply press
the button again (one long single
beep).
4.After 30 minutes of forced operation,
the air conditioner automatically

Device specications and features
The air sucked out of the fan comes
from the grate and ows through the
lter. It is then cooled/dehumidied or
heated up by the heat exchanger.
The direction of the air exhaust is driv-
en up and down by motorised lamellae
and is moved manually to the right and
left by the vertical deectors.

Fan
Deectors must only be adjusted
when the device is switched off.
Airow swing control
• The air exhaust ow is distributed
around the room evenly.
• There is an optimal setting for the air
direction.
The ( )button activates lamella
movement. The airow is directed up
and down alternately. This guarantees
even distribution of air within the room.
• In COOL mode, the lamellae must be
adjusted horizontally.
• In HEAT mode, the lamellae must be
adjusted vertically, as hot air tends to
rise.
The deectors are set manually and
are located under the lamellae. These
allow you to direct the airow to the
right or left.
