NOTICE
The height of the wall on the outlet side of the outdoor unit
MUST be ≤1200 mm.
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.
INFORMATION
The sound pressure level is less than 70 dBA.

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
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.
