Note 1 : The cooling capacities and electrical characteristics are measured under the conditions speciied by JIS B 8616 based
on the reference piping 7.5m.
Note 2 : The sound level is measured in an anechoic chamber in accordance with JIS B8616. Normally, the values measured in
the actual operating environment become larger than the indicated values due to the effects of external sound.
Note : Rated conditions Cooling : Indoor air temperature 27°C DB/19°C WB, Outdoor air temperature 35°C DB
Heating : Indoor air temperature 20°C DB, Outdoor air temperature 7°C DB/6°C WB
