7 - POSITIONING AND INSTALLATION
7.4 Sound level
These units are designed to work with a low acoustic level. In any case, the following must be taken into account for the design
of the installation: the outdoor environment for acoustic radiation, the type of building for the noise transmitted by air, the solid
elements for the transmission of vibrations.
To reduce transmission through solid surfaces to the maximum, it is very advisable to install shock absorbers between the ground
or structure and the unit frame. If necessary, a study must be commissioned to an acoustic technician.
Note: The acoustic insulating cover for compressor (optional) achieves a sound level reduction of approximately 2 dB(A).
