Calculate the operation noise when external air is being fed by combining the noise when only
external air is being fed as shown in the graph for operation noise characteristics and the operation
noise of the unit as stipulated in the catalogue.
The operation noise conforms to JIS standards and constitute measurements taken in an anechoic
chamber 4.9 ft. (1.5m) directly beneath the indoor unit. Under normal circumstances, the values shown here
are greater owing to the effects of surrounding noise and reverberation when the unit is actually installed.

For use with mini cassettes
The operation noise for models that use small units is lower,
so use values that are within the range shown in the above table.
Using values that exceed these will result in noise when only
external air is fed being louder than the noise emitted from the unit.
