1
Sound pressure level in (x)m of the device, 1,5m of the ground, the open field.
2
The sound power level is a laboratory measure of the emitted sound power
but contrary to the noise level, it doesn't correspond to the measure of the felt.
3
Refrigerant R410A (as per the standard EN 378.1).
4
Factory charge of refrigerant R410A.
5
