The declared A-weighted soundpower level LWAd must not exceed the limits in the tables below.
The sound power level for eco mode must be at least 0,2 B(A) lower than the declared sound power level during normal operating mode.
Declarerad A-weighted sound power level LWAd shall be measured according to ISO 9296:1988 and declared according to ISO 7779:1999, unit bel (B) or decibel (dB), or equivalent standards.
