13 - SOUND EMISSION
A sound level measurement has been gauged by measuring the acoustic pressure and the sound
level of the vacuum cleaner. The test report is held at the producer headquarters.
14 - IDEAL LOCATION OF THE VACUUM CLEANER TO REDUCE SOUND
EMISSION
The following suggestions and measures will help reducing the sound emissions of the vacuum
cleaner:
• Fix the system to a solid wall (not to a cavity wall), preferably made of solid bricks.
• Avoid fi xing the system to an internal dividing wall, it is better to fi x it to an external perimeter
wall.
• You can also use sound-absorbing materials on the two side walls if these are very close to
each other; this will interrupt the sound wave and avoid resonance phenomena between the
two waves which could refl ect on the two opposite walls.
• You could possibly also soundproof the ceiling.
15 - VIBRATIONS
There is no contact between the hand, arm or body of the operator and the machine when vacuum
cleaning using the fl exible hose; for this reason there is no risk related to vibrations.
