3. OUTDOOR UNIT INSTALLATION
3.1 GENERAL INDICATIONS
When choosing the installation position, carefully observe the
following indications:
- Make sure that the difference in height between the U.I./U.E.
OUTSIDE is not greater than 5.0 m.
- The appliance must be installed so that the influences
of adjacent structures and / or the effects of particular climatic
conditions (snow, wind, etc.), do not compromise the
functioning of the product and / or the safety of people and
goods.
- Make sure that the space in the back of the unit is
greater than 30 cm. The front must have more than 60 cm.
of space.
- Make sure there are no obstacles to free movement of the air
through the heat exchangers:
A) do not place plants or animals directly close to the air flow;
B) avoid installation in corners where dust, leaves and anything
else usually can reduce the efficiency of the
exchangers by obstructing the passage of air (Fig 6).

- Avoid installation in bottlenecks and small shafts as acoustic
reverberations could be favored. Inquire about any limits in
noise emissions provided for the area of the municipal area
where the appliance is installed. In case of doubt, it is advisable
to consult an acoustic technician in advance, qualified for an
impact assessment, in order to prevent complaints from third
parties.
- Prevent the air expelled from the fans from penetrating through
adjacent doors and / or windows, causing situations disturbing
people.
- Install the outdoor unit on a rigid base equipped with
appropriate anti-vibration bearings to avoid the increase of
vibrations and noise, so as not to disturb neighbors (Fig.7).

- Position the air outlet so that the flow is not hindered in any
way. In the case of strong wind, make sure that the fan works
correctly, positioning the unit longitudinally, along a wall or
using a shield.
- If the appliance is to be suspended from an external wall, the
substrate must comply with the techn. specifications. The wall
where the unit must be installed, it must be brick or material of
similar consistency,otherwise it must be reinforced.The
support brackets must be stable, resistant and with an
adequate degree of protection against corrosion.
WARNING! Make sure of the load-bearing capacity of the
part on which the shelves are placed and of the anchoring
system to the wall itself, according to the weight of the
appliance to be installed.
- Do not install the appliance near heat sources and / or fire risk
areas.
- Installation in areas with a highly corrosive atmosphere not is
allowed; in particular climatic conditions such as near the sea,
it is mandatory to provide a shorter life span of the product and
in any case a more frequent and accurate maintenance.
- In the outdoor unit, from which the water of condensation,
provide for a suitable drainage and / or channeling of the
same, in order to avoid dangerous situations due, for example,
to the formation of ice on passage areas.
- The outdoor unit is designed to be installed outdoors and
it does not require a special base, however it must be safely
positioned on a horizontal support surface with adequate
load-bearing capacity and equipped with special anti-vibration
rubber pads.
