INSTALLATION INSTRUCTIONS
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.
The documentation for accessories supplied loose
included with each kit.
DANGER!
The machine is designed for outdoor installation.
Segregate the unit if installed in areas accessible to
persons under 14 years of age.
DANGER!
Some internal parts of the unit may cause cuts. Use
suitable personal protective equipment.
DANGER!
When the outdoor temperature is around zero, the
water normally produced during the coil defrosting
could form ice and make the flooring near the unit
installation area slippery.
If the unit is not fixed to anti-vibration mounts, once it has been set on
the ground, it must be firmly bolted down to the floor using M6 metric
threaded bolts. Slots are provided in the base for this purpose.
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.5.1.1
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.

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.
The unit is designed for outdoor installation. The unit must be installed
in compliance with the minimum recommended technical spaces,
bearing in mind the access to the water and electrical connections. 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.

IMPORTANT!
Incorrect positioning or installation of the unit may
amplify noise levels and vibrations generated
during operation.
The following accessories are available to reduce noise and vibration:
Anti-vibration mountings.
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;
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, refer to a qualified
acoustic technician for a complete analysis of the problem.
