6.3.3.2
Spring anti-vibration mounts
The cylindrical spring anti-vibration mounts are suitable for isolating any source of mechanical vibration. Each anti-vibration
mount bears a code that identifies the maximum load allowed.
It is very important to strictly comply with the assembly recommendations and instructions when installing the anti-vibration
mounts.
Standard spring anti-vibration mounts: the frame of the unit is mounted on the anti-vibration mount with the through-screw
and 2 washers.
Spring anti-vibration mounts for heavy loads: the load of the unit is borne by the entire surface of the anti-vibration mount
and not just by the screw.

6.3.4 Noise attenuation
The units are designed and built paying particular attention to keeping down noise emission during operation.
In addition to the standard versions, there are “LN” (Low Noise) versions for which further devices are used for lower noise
emission.
Correct installation for both the place and the components, as shown in the relevant chapter, avoids resonances, reflections
and vibrations that can be particularly bothersome.
If, after following the instructions above, further attenuation is required, the use of acoustic barriers is a valid solution.
It is essential to be careful that any work done to soundproof the unit does not affect its correct installation or its correct
operation.
That is why it is necessary to avoid limiting the service spaces.
6.3.5 Minimum distances
The service spaces to comply with are shown on the dimensional drawings attached to the documentation of the unit.
It is, in any case, advisable to leave sufficient space between the units to allow removal, if necessary, of their larger compo

nents such as the exchangers, compressors or pumps.
As for a possible remote heat exchanger, see the relevant documentation.
