1-9-2-3. In a Case of External Air Intake to Unit Directly(Using external air intake cylindrical flange)
1. 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 diagram for operation noise characteristics and the operation noise of the unit as stipulated in the catalogue.
2.
The amount of external air intake that is possible to feed when it is fed directly into the unit
* 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.

The operation noise conforms to JIS standards and constitute measurements taken in an anechoic chamber 1m front
and 1m below the indoor unit. Under normal circumstances, the diagram shown above is greater owing to the effects of
surrounding noise and reverberation when the unit is actually installed.
