(5) Mike positions of measureing sound pressure level
of indoor unit is shown below.
Notes (1) The data are measured at the following conditions.
The pipe length is 5m.
(2) This air-conditioner is manufactured and tested in conformity with the ISO.
(3) Sound level indicates the value in an anechoic chamber. During operation these values
are somewhat higher due to ambient conditions.
(4) Select the breaker size according to the own national standard.
