Noise Attenuation; Minimum Distances - Daikin UATYA-BBAY1 Manuel D'installation, D'utilisation Et D'entretien

5.3.2

Noise attenuation

The units are designed and built paying particular attention to keeping down noise emission during operation.
In addition to standard versions, the company offers versions with the compressor compartment coated with sound
absorbing material for lower noise emissions.
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 that any work done to soundproof the unit does not affect its correct installation or its correct operation.
That is why it is necessary not to restrict the service spaces and to avoid installing covers that create recirculation
between air supply and intake.
5.3.3

Minimum distances

The service spaces to comply with are shown on the dimensional drawings attached to the documentation of the unit.
It is essential to ensure an adequate volume of air on the suction and delivery side of the condensing coil.
It is very important to avoid recirculation between suction and delivery, as this would lower the performance of the unit
or even stop its normal operation.
The presence of very high walls near the unit will impair its correct operation.
Units should be installed a minimum of three metres apart.
It is advisable to leave sufficient space between units to allow their larger components, such as heat exchangers and
compressors, to be removed if necessary.
