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.
The outdoor unit is designed for outdoor installation only, and for
ambient temperatures within the following ranges (unless otherwise
specified in the operation manual of the connected indoor unit):
Cooling mode

It is recommended to provide at least 150 mm of free space below
the unit (300 mm for heavy snowfall areas). Additionally, make sure
the unit is positioned at least 100 mm above the maximum expected
level of snow. If necessary, construct a pedestal. See
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.

Mounting the outdoor unit
4.2.1
To provide the installation structure
Use a vibration-proof rubber (field supply) in cases where vibrations
may be transmitted to the building.
The unit may be installed directly on a concrete veranda or another
solid surface as long as it provides proper drainage.
Prepare 4 sets of M8 or M10 anchor bolts, nuts and washers (field
supply).
