The outdoor unit must be installed such that there is no short
circuit of the hot discharge air or obstruction to the smooth
air flow. Please follow the installation clearance shown
below. Select the coolest possible place where intake air
temperature is not greater than the outside air temperature
(maximum 45°C).
Installation Clearance
Note : If there is any obstacle higher than 2m, or if there is
any obstruction at the upper part of the unit, please allow
more space than the figure indicated in the above table.

Installation
The indoor unit must be installed in such a way so as to
prevent short circuit of the cool discharged air with the hot
return air. Please follow the installation clearance shown in
the figure. Do not place the indoor unit where there could
be direct sunlight shining on it. Also, this location must be
suitable for piping and drainage, and be away from doors
or windows.

Mounting Installation Plate
Ensure that the wall is strong enough to withstand the weight
of the unit. Otherwise, it is necessary to reinforce the wall
with plates, beams or pillars.
Use the level gauge for horizontal mounting, and fix it with
4 suitable screws.
In case the rear piping draws out, drill a hole 65mm in
diameter with a cone drill, slightly lower on the outside wall
(see figure).
