• We recommend that you check whether
the noise pollution requirements related
to the environment of the installation are
consistent with the acoustic power and
pressure data reported in the "Technical
data" chapter and the noise emission limits
depending on the the unit’s installation
area, see chapter 3.3.2, in accordance with
standard EN-12102. This assessment is the
responsibility of the installer.
• In the case of winds with speeds above 13.9-
17.1 m/s (strong wind on the Beaufort scale)
we recommend the use of wind barriers.
• These minimum clearances must be
respected regardless of the installation to
guarantee the performances and safety of
the unit.
• Generally, any possibility of air recirculation
should be avoided, as this will degrade the
performance of the machine.
• In the event of an accidental leak, the
refrigerant must not be allowed to stagnate
and it must be possible to evacuate it.
• In the case of an installation under a shelter
or in an enclosed place, a ducted version is
recommended. Please refer to paragraph
1.2.3

The figure shows an example of a possible ducted installation. Before making any change to the
direction of the duct, the minimum length to be observed is indicated ( L = 1 m). The following
is a quantitative indication of the additional static height that can be obtained with the ducted
version compared to the standard version, with the same flow rate and the same absorbed
power. Pressure drops that are any greater will not guarantee the declared performance.
