FEATURES

Energy saving

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.

Installation styles

Embedded in Ceiling

Hanging from Ceiling

Slim & compact design

In the case of bottom suction type, as seen from lower rear part.

Control Box united with main unit

One-touch operating and easy-to-install
long-life filter (optional)

In addition to the slim height of 270 mm which is our sales point, further com­pactification is attained by reducing 65 mm from the width with the flanking
control box embedded inside the chassis.

Bottom panel: 2 units

The motor and fan maintenance and dismounting can be made easily by removing
the rear panel and lower part of the casing with the main chassis installed.

Quiet operation

Quiet operation at *29dB(A) possible by quiet mode.

* See our measurement conditions page (01-19).

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.
