FEATURES

Energy saving
z
High energy saving was realized converting indoor unit/outdoor unit fan motors and compressor to
ALL DC, and also by optimal design of the refrigerant cycle.
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, 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) is possible in quiet mode.
Economy operation
z
The power consumption can be reduced.
