Noise emissions in the environment measured as sound power (L
WA
) in conformity with EC di-
rective 2000/14/EC and New South Wales legislation (Protection of the Environment Operations
Regulation 2017, Noise Control). The guaranteed sound power level includes variation in pro-
duction as well as variation from the test code with 1-3 dB(A). Noise emission data can be found
on the rating label and in the Technical data chapter.
