characteristics
Note 1 : The cooling capacities and electrical characteristics are measured under the conditions specified by JIS B 8616
based on the reference piping length 7.5 m with 0 meter height.
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
