Reference conditions: external air temperature 30°C; evaporator inlet/outlet water temperature 15/10°C; unit without accessories
operating at nominal speed.
Lw: sound power levels obtained from measurements carried out in accordance with standard ISO 3744. In particular, Lw tot is the
only binding value and complies with the Eurovent certification programme (8/1) where applicable.
Lp: Lp: sound pressure levels measured at a distance of 10 metres from the unit in free field with directivity factor Q=2. These val-
ues (including Lp tot) are calculated starting from the sound power levels and are therefore to be considered approximate and
non-binding.
