NOTICE
The height of the wall on the outlet side of the outdoor unit
MUST be ≤1200 mm.
Do NOT install the unit in sound sensitive areas (e.g. near a
bedroom), so that the operation noise will cause no trouble.
Note:
If the sound is measured under actual installation conditions,
the measured value might be higher than the sound pressure level
mentioned in "Sound spectrum" in the data book due to
environmental noise and sound reflections.
INFORMATION
The sound pressure level is less than 70 dBA.
