side, when the wall of rear side is higher than 500mm.
* Add the half of dimension h2 to 1500 for air intake space of front
side when the wall front side is higher than 1500 mm
§
Install the outdoor unit where a good ventilation is
available.
§
Install the outdoor unit where it is in the shade or it will
not be exposed to direct sunshine or direct radiation
from high temperature heat source.
§
Install the outdoor unit where the falling ice from the
unit will not create a hazard, as in the case of
installation on top of a building where ice may fall
down on the pedestrians.
§
Install the outdoor unit where the sound or discharge
air from the outdoor unit does not affect neighbors or

Install the outdoor unit as far as practical at least 3
meters from the electromagnetic wave radiation, as
electronic noise can cause miss-operation of the unit.
