Preparing the installation site
CAUTION
▪ Check if the installation location can support the unit's
weight. Poor installation is hazardous. It can also cause
vibrations or unusual operating noise.
▪ Provide sufficient service space.
▪ Do NOT install the unit so that it is in contact with a
ceiling or a wall, as this may cause vibrations.
▪ Choose the installation location with sufficient space for carrying
the unit in and out of the site.
WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).

NOTICE
The height of the wall on the outlet side of the outdoor unit
MUST be ≤1200 mm.
It is recommended to install a baffle plate when the air outlet is
exposed to wind.
It is recommended to install the outdoor unit with the air inlet facing

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.
3.1.2
Additional installation site requirements
of the outdoor unit in cold climates
Protect the outdoor unit against direct snowfall and take care that the
outdoor unit is NEVER snowed up.

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.
