Wind deflector
• Install the unit so that the air outlet fan is at a 90°
angle to the wind direction. If necessary, build
a barrier in front of the unit to protect it from
extremely strong winds.
• If the device is often exposed to heavy rain or snow,
it is advisable to build a shelter above the unit to
protect it. Be careful not to obstruct the flow of air
around the unit.
IF THE UNIT IS EXPOSED TO STRONG WINDS
CHOOSING THE INSTALLATION AREA FOR THE
OUTDOOR UNIT
MINIMUM TECHNICAL CLEARANCES
• To guarantee the unit operates correctly, the choice
of location for the installation must meet the
following criteria:
• The outdoor unit must be installed so as to ensure
that air discharged from the unit itself is not
recirculated and there is sufficient space around the
machine for operations and maintenance.
• The installation site must be well-ventilated so that
the outdoor unit can take in and discharge sufficient
quantities of air. Ensure that there are no obstacles
near the outdoor unit’s air inlets or outlets. Remove
any obstacles which may be blocking the intake or
discharge of air.
• The site of the installation must be sufficiently solid
to bear the weight of the outdoor unit, and it must
also be able to absorb any vibrations and insulate
against noise. Ensure that the air and noise coming
from the unit do not disturb your neighbours.
• The site of the installation must ensure that the
outdoor unit cannot become buried in snow and it is
not subject to the effects of fumes from fuel and oils.
• Avoid direct exposure of the unit to solar radiation: it
is recommended to install protection.
• The installation site must guarantee drainage of
rainwater and water produced during the defrosting
cycle.
• Always ensure adequate condensate drainage is
installed.
• Position the unit so that the discharge air supply is
not exposed to strong winds. The exhaust air must
be free to be released into the environment.

WARNINGS CONCERNING INSTALLATION
The unit and its accessories must only be installed and
wired by professionals with the necessary technical
qualifications in installation, conversion, extension and
maintenance of the systems and who are trained to per-
form operational and safety checks on these systems. In
this manual, these will generally be referred to as “Per-
sonnel with specific technical skills”.
• Before installing, refer to the technical plate inside
the unit itself to make sure the indoor unit model cor-
responds to the outdoor unit model to be installed.
• Check that the power supply is disconnected before
carrying out any operations on the unit.
• Incorrect installation can result in water leaks, electro-
cution or fires.
• After a prolonged period of use, check that the instal-
lation conditions of the unit have not been altered,
and have the system checked by a qualified engineer.
• Do not make any modifications to the unit! Do not
attempt to repair the unit alone, this is extremely
dangerous!
• Incorrect operations could cause electric shocks, wa-
ter leaks, fires etc.
• After disconnecting the power supply, wait at least 10
minutes before touching the electrical components
(risk of electric shock). Never touch the electrical
components immediately after disconnecting the
power supply.
• Contact your local dealer or After Sales Service: these
operations must only be carried out by “Personnel
with the specific technical skills”.
INSTALLATION AND TRANSPORT
• Transportation must be carried out by experts.
• The unit and its accessories must only be installed
and wired by professionals with the necessary tech-
nical qualifications in installation, conversion, exten-
sion and maintenance of the systems and who are
trained to perform operational and safety checks on
these systems. In this manual, these will generally be
referred to as“Personnel with specific technical skills”.
• For the installation, be sure to use only the acces-
sories and parts specified; failure to observe this
precaution may result in electric shocks, electric dis-
charge or fires.
• When carrying out the installation, take into consid-
eration strong winds, typhoons and earthquakes. In-
correct installation could cause the device to fall, and
lead to accidents.
• If the unit needs to be moved to another place, con-
sult your local retailer or the After Sales Service be-
forehand; this should only be carried out by “Person-
nel with specific technical skills”.
• To ensure good drainage, the condensate discharge
pipes must be correctly installed, following the instal-
lation instructions. Adopt the most suitable measures
to avoid heat dispersion and the consequent forma-
tion of condensate. Incorrect installation of the pipes
can result in water leaks, wetting furniture and other
items in the room.
• Make sure the cables don't touch or rest against the
refrigerant tubes, the compressor, or moving parts
inside the unit.
NOISE
• Choose a well-ventilated area, to avoid reduced per-
formance or increased noise.
• Choose a position where the hot air or noise emitted
from the outdoor unit will not disturb your neigh-
bours.
• Never place objects near the air outlet or the unit, as
this could reduce performance or increase the noise
level.
• If abnormal noises are heard during operation, con-
tact the local After Sales Service immediately.
INSTALLATION POSITION
• It’s always advisable to install the indoor unit in a
point where the air can easily reach every corner of
the room.
• Install on a solid surface which can bear the weight of
the air conditioner.
• Do not install the unit in places or on surfaces that
move and are not stable, such as a lorry.
• Check the support is securely installed and the unit
is absolutely stable after operating for a long time. If
it is not securely fixed, the unit could fall and cause
injuries.
• Have the installation checked periodically, 3-4 times a
year, by“Personnel with specific technical skills”.
• Avoid places that can be reached by children, and
keep it away from animals and plants. If unit instal-
lation in places like these cannot be avoided, you are
advised to fit some form of protection.
• Avoid places within the reach of children.
• Avoid exposure to other heat sources or to direct sun-
light.
• Install the indoor unit away from TV, radio and other
electrical equipment.
• Avoid installing the unit near high-frequency devices
such as welders or medical equipment.
• Do not install the unit in a location where it could be
affected by inflammable gas leaks. This could start a
fire. Install the unit in a location with minimal levels of
dust, fumes and humidity in the air.
