* Cooling capacities and electrical data are measured at the conditions specified by JIS B 8615, based on the reference piping which consists of 5 m of main
piping and 2.5 m of branch piping connected with 0 metre height.
** The sound pressure level is measured in an anechoic chamber in accordance with JIS B 8616. Normally the values measured in the actual operating
environment become larger than the indicated values due to the effects of external sound.
