Sound level

These units have been designed to operate with a low sound level.
In any case, in the design of the installation, it must be taken into
consideration: the outdoor environment for the acoustic radiation,
the type of building for the noise transmitted in the air and the solid
elements for the vibration transmission.
To reduce the transmissions through solid matter to the maximum,
we recommend installing damping devices between the fl oor or
structure and the frame of the unit and fl exible connections in the
hydraulic tubes.
If necessary, an acoustic technician must commission a study.
