difficulty of exchange
leaves or other bodies that can obstruct the exchange
coils
winds contrasting or favouring the air flow
heat sources near the unit (chimneys, extractors, etc.)
sources of dust or pollutants
stratification (cold air that stagnates at the bottom)
recirculation (ejected air that is taken back via suction)
positioning underneath the ground level, near very
high walls, underneath roofs or in corners (can give
rise to stratification or recirculation phenomena).
Neglecting the previous indications can lead to:
worsening of the energy efficiency.
blocks due to HIGH PRESSURE (in summer) or LOW
PRESSURE (in winter).
Avoid snow and ice accumulation in front of the external air
outlets and of the exhaust air ejection.

3 - POSITIONING
The functional spaces have the aim of:
guarantee good operation of the unit
allow maintenance operations
protect the authorised operators and exposed
persons.
Respect the functional spaces indicated in the TECHNICAL
INFORMATION chapter
Double the functional spaces if more units are aligned.
The units have been designed to be installed :
OUTDOORS
INDOORS (OPTION)
in permanent position.
Choose the place of installation depending on the following
criteria:
level of sound emissions admitted by the local
standards
Customer approval
safely accessible position
technical spaces requested by the unit
maximum distance admitted from the electric
connections
support points with adequate capacity for the unit
weight
spaces for air ejection and suction
disposal of condensate water
Prefer places where the unit does not disturb neighbours.
Avoid snow accumulating obstructing the coils
Avoid places that may be subject to floodings
Install the unit lifted from the ground.
Protect the unit with suitable fence in order to avoid
access to unauthorised personnel (children, vandals, etc.)
Limit the transmission of vibrations:
use anti-vibration devices or neoprene strips on the
unit support points
install flexible joints on the hydraulic connections
install flexible joints on the aeraulic connections.
A correct air circulation on the coil is essential to guarantee the
good operation of the machine.
Avoid:
obstacles to air flow (strong prevailing winds, hedges,
fences, etc.)
Work respecting the current safety standards.
For detailed information (dimensions, weights, technical
features, etc.) refer to the TECHNICAL INFORMATION
chapter.
To perform the operations use the protective equipment:
gloves, goggles, etc.
