• Measurement taken 4.9' above finished floor, and at a distance of
3.3' from face of unit.
• Measurements taken with no attenuation and units operating at full
load normal operating condition.
• Sound level will vary depending on a range of factors such as
construction (acoustic absorption coefficient) of particular area in
which the equipment is installed.
• Sound level may be increased in static pressure mode or if air
guide is used.
• Sound pressure levels are measured in dB(a)±3.
• tested in anechoic chamber per iSO Standard 3745.
