Universal design indoor unit (AR 18L)
Since vertical and horizontal installation is possible, and the intake direction can also be selected
from two directions, flexible installation is possible.

When installed, normal middle static pressure mode, and low static
pressure mode can be selected by switching over using DIP switch
on the board in the control box. Therefore, these models can be
operated under the wide range of conditions.
Slim & compact design (AR 24L)
In the case of bottom suction type, as seen from lower rear part.
Control Box that has been convex shape
is now united with main unit (DIP Switch is
located on the internal substrate.)
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.

Structural improvement is attained by making the bottom panel two pieces, front and
rear, and the internal fan casing is also made dismountable in two pieces namely,
upper and lower ones.
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.
