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 condi-
tion by surrounding echoes. The sound level can be higher
by about 2 dB than the displayed level during cooling and
heating operation.
