4-5. Noise level (Sound pressure level)
♦The sound pressure level is a value measured in an anechoic room in accordance with the conventional
method in JIS standard. The sound pressure level actually measured at the installation site is usually higher
than the indicated value in this catalogue due to the influence of ambient noise and echoes.
Valve operation noise and refrigerant flow noise may occur from inside the outdoor unit/heat-source unit.
