FEATURES
Energy saving (AO A18LACL, AO A18LALL connection model)
High energy saving was realized by making the indoor unit and outdoor
unit fan motor and compressor all DC and optimal design of the refrigerant cycle. Rank A was achieved in European energy rank.
Universal design indoor unit
Since vertical and horizontal installation is possible, and the intake direction can also be selected
from two directions, flexible installation is possible.

Thin and compact indoor unit
Quiet mode
Operation at *27dB(A) possible by Quiet Mode.
* See our measurement conditions page (01-16).
FUNCTION SETTING
Static pressure mode setting
Air flow, noise, etc. can be used under the optimum conditions by selecting
the static pressure mode matched to the installation conditions.
Room temperature adjustment correction
Suitable room temperature control is performed by changing the room temperature correction value
by simple remote control operation to match the conditions under which the air conditioner is installed.
Auto restart
The units restart automatically when the current was returned even when
there was a power interruption during operation.
