II.5
INSTALLATION
DANGER!
Installation must only be carried out by skilled
technicians, qualified for working on air
conditioning and refrigeration systems. Incorrect
installation could cause the unit to run badly, with a
consequent deterioration in performance.
DANGER!
The unit must be installed according to national or
local standards in force at the time of installation.
DANGER!
Some internal parts of the unit may cause cuts. Use
suitable personal protective equipment.
IMPORTANT!
The unit is designed for outdoor installation.
Incorrect positioning or installation of the unit may
amplify noise levels and vibrations generated
during operation.
II.5.1
Installation site requirements
The installation site should be chosen in accordance with the provisions
of Standard EN 378-1 and in keeping with the requirements of Standard
EN 378-3. When selecting the installation site, risks posed by accidental
refrigerant leakage from the unit should also be taken into
consideration.
II.5.2
Outdoor Installation
Machines designed for outdoor installation must be positioned so as to
avoid any refrigerant gas leakage entering the building and posing a
hazard to people's health.
If the unit is installed on terraces or building roofs, adequate safety
measures must be taken in order to ensure that any gas leaks cannot
enter the building through ventilation systems, doors or similar
openings.
In the event that the unit is installed inside a walled-in structure (usually
for aesthetic reasons), these structures must be suitably ventilated in
order to prevent the formation of dangerous concentrations of
refrigerant gas.
II.5.3
Clearance and positioning
IMPORTANT!
Before installing the unit, check the noise limits
allowed in the place where it will be used.
IMPORTANT!
The unit should be positioned to comply with the
minimum recommended clearances, bearing in
mind the access to water and electrical
connections.
IMPORTANT!
If clearance distances are not maintained at
installation, it could cause malfunctioning with an
increase in absorbed power and a considerable
reduction in cooling capacity.
SECTION II :: INSTALLATION AND MAINTENANCE
The unit is designed for outdoor installation. The unit should be
correctly levelled and positioned on a supporting surface capable of
sustaining its full weight. It must not be installed on brackets or shelves.

(*) The distance must be increased by 1m to facilitate special
maintenance on the unit and to be able to remove the tube and shell
heat exchanger accessory (STE) or any pump unit present.
N.B.
The space above the unit must be free from obstacles. If the unit is
completely surrounded by walls, the distances specified are still valid,
provided that at least two adjacent walls are not higher than the unit
itself.
The minimum gap between the top of the unit and any obstacle above it
is 3,5 m.
If more than one unit is installed, the minimum distance between the
finned coils should be at least 2 m.
However it is installed, the coil inlet air temperature (ambient air) must
remain within the set limits.
When installing the unit, bear the following in mind:
non-soundproofed reflecting walls near the unit may increase the
total sound pressure level reading near the appliance by as much as 3
dB(A) for every surface;
install suitable anti-vibration mountings under the unit to avoid
transmitting vibrations to the building structure (SAM – Anti-vibration
mountings);
make all water connections using elastic joints; pipes must be firmly
supported by solid structures. If the pipes are routed through walls or
panels, insulate with elastic sleeves.
II.5.4
Reduction of unit's noise level
Correct installation envisions taking measures aimed at reducing the
noise inconvenience from the unit's standard operation.
When installing the unit, bear the following in mind:
non-soundproofed reflecting walls near the unit, such as terrace
walls or building perimeter walls, may increase the total sound pressure
level reading near the appliance by as much as 3 dB(A) for every
surface (e.g. a 6 dB(A) increase corresponds to 2 corner walls);
install suitable anti-vibration mountings under the unit to avoid
transmitting vibrations to the building structure;
on top of buildings, solid floor frames can be provided which support
the unit and transmit its weight to the support elements of the building;
make all water connections using elastic joints; pipes must be firmly
supported by solid structures. If the pipes are routed through walls or
panels, insulate with elastic sleeves.
If, after installation and start-up of the unit, structural vibrations are
observed in the building which provoke such strong resonance that
noise is generated in other parts of the building, consult a qualified
acoustic technician for a complete analysis of the problem.
