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.
