directive 2000/14/EC and New South Wales legislation (Protection of the Environment Op-
erations Regulation 2017, Noise Control). The guaranteed sound power level includes var-
iation in production 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.
