outdoor units
•
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 power levels are measured in dB(A)±3.
•
Tested in anechoic chamber per ISO Standard 3745.
