Do NOT install the unit in sound sensitive areas (e.g. near a
bedroom), so that the operation noise will cause no trouble.
Note: If the sound is measured under actual installation conditions,
the measured value might be higher than the sound pressure level
mentioned in "Sound spectrum" in the data book due to
environmental noise and sound reflections.

In any case, provide at least 300 mm of free space below the unit.
Additionally, make sure the unit is positioned at least 100 mm above
the maximum expected level of snow. See
outdoor unit" on page 7
for more details.
In heavy snowfall areas it is very important to select an installation
site where the snow will NOT affect the unit. If lateral snowfall is
possible, make sure that the heat exchanger coil is NOT affected by
the snow. If necessary, install a snow cover or shed and a pedestal.
