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

Install the outdoor unit where the sound or discharge
air from the outdoor unit does not affect neighbors or

When installing the outdoor unit in snow-covered
areas, mount the field-supplied hoods on the top of
the outdoor unit and the inlet side of the heat
exchanger.

sulfur.
-
Do not install the outdoor unit where electromagnetic
waves are directly radiated to the electrical box and
inverter components.

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.
