Performance certified is for installation type B: Free inlet, Ducted outlet. Power rating (Bhp) does not include transmission losses. Performance ratings do not include the
effects of appurtenances (accessories). The sound power level ratings shown are in decibels, referred to 10-12 watts, calculated per AMCA Standard 301. Values shown
are for inlet LwiA sound power levels and inlet hemispherical sone levels for installation type B: Free inlet, Ducted outlet, calculated per AMCA Standard 301. The AMCA
Certified Ratings Seal applies to air performance and LwiA values only.
