Table 61:Sound Pressure Levels (dB[A]).
• To get the desired air flow and external static pressure combination, use the setting value from the table. Using a setting value other
than that listed in the table will not provide the desired combination.
• Table data is based at 230V. Air flow rate varies according to voltage fluctuation.

• 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).
• Tested in anechoic chamber per ISO Standard 3745.
