shown below.
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 environment.
Check to ensure that the foundation is flat and sufficiently
strong.
Do not install the outdoor unit where dust or other
contamination could block the outdoor heat exchanger.
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.
Do not install the outdoor unit where there are high-levels of
oil mist, salty air or aggressive gases such as 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.
