4.3 Positioning and assembly
All units are designed for installation outdoors, i.e. on balconies or on the ground, provided that the installation area is free
of obstacles that could reduce air flow to the condensers coils.
The unit must be installed on a robust and perfectly level foundation; should the unit be installed on balconies or roofs, it
might be necessary to use weight distribution beams.
For installation on the ground, a strong concrete base, at least 250 mm thickness and wider than the unit must be provided.
This base must be able to support the weight of the unit.
The unit must be installed above antivibration mounts (AVM), rubber or spring types. The unit frame must be perfectly
levelled above the AVM.
Installation such as in the Fig. 22 must always be avoided. In case the AVM are not adjustable, the flatness of the unit
frame must be guaranteed by using metal plate spacers.
Before unit commissioning, the flatness must be verified by using a laser levelling device or other similar devices. The
flatness shall not be over 5 mm for units within 7 m length and 10 mm for units over 7 m.
If the unit is installed in places that are easily accessible to people and animals, protection grids for the unit shall be
installed.
To ensure the best performance on the installation site, the following precautions and instructions must be followed:
- avoid air flow recirculation;
- make sure that there are no obstacles to hamper air flow;
- make sure to provide a strong and solid foundation to reduce noise and vibrations;
- avoid installation in particularly dusty environments, in order to reduce soiling of condensers coils;
- the water in the system must be particularly clean and all traces of oil and rust must be removed. A mechanical
water filter must be installed on the unit inlet piping;
- avoid the refrigerant discharge from the safety valves at the installation site. If necessary, it is possible to connect
them with exhaust pipes whose cross-section and length must comply with national laws and European directives.

4.3.1 Noise and sound protection
The unit is a source of noise mainly due to rotation of compressors and fans.
The noise level for each model size is listed in sales documentation.
If the unit is correctly installed, operated and maintained, the noise emission level do not require any special protection
device to operate continuously close to the unit without any risk.
In cases where the installation is subject to compliance with special sound requirements, it may be necessary to use
additional noise attenuation devices. It is necessary to isolate the unit from its base with extreme care, correctly applying
the anti-vibration elements, supplied as optional (Fig.23) . Flexible joints must be installed on the water connections, as
well.
