1.3 Specications
1
Sound pressure level in (x)m of the device, 1,5m of the ground,
the open eld.
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
Taking into account the possible additional load of refrigeration uid
R410A (see "Additional charge", page 21).
