3-12. SOUND PRESSURE LEVELS
NOTE: The sound level is measured in an anechoic room where echoes are few, when compressor stops. The sound
may be bigger than displayed level under actual installation condition by surrounding echoes. The sound level
can be higher by about 2 dB than the displayed level during cooling and heating operation.
