Energy saving
z
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.
Class A was achieved in European energy classications.
Flexible installation
z
A high installation of degree of freedom according to the construction of the ceiling.
Slim & compact design
z
In the case of bottom suction type, as seen from lower rear part.
In addition to the slim height of 270 mm which is our sales point, further compactication is
attained by reducing 65 mm from the width with the anking control box embedded inside the
chassis.

Easy maintenance
z
It can easily access the fan and the motor by the divided panel structure.
Structural improvement is attained by making the
bottom panel two pieces, front and rear.
The internal fan casing is also manufactured
in two pieces, namely upper and lower. The
maintenance of the motor and fan can be easily
carried out by removing the rear panel and the
lower part of the casing while leaving the main
chassis installed.
Quiet operation
z
Quiet operation at *28dB(A) [45 type] possible by quiet mode.
* See our measurement conditions page (01-16).
FUNCTION SETTING

Static pressure mode setting
z
Air ow, noise, etc. can be used under the optimum conditions by selecting the static pressure
mode matched to the installation conditions.
Room temperature sensor switching
z
Switches from room temperature judgment by room temperature sensor attached to indoor
unit body to room temperature judgment by room temperature sensor attached to wired remote
controller.
Auto restart
z
The units restart automatically when the current was returned even when there was a power
interruption during operation.
Economy operation
z
The power consumption can be reduced.
Powerful mode ...Standard
Soft mode ...Performs operation which reduces the power consumption
