** The amount does not consider extra piping length. Refrigerant
must be added on site in accordance with the actual piping length.
†† Select wire size based on larger value of MCA.
*** In case the diversity exceeds 135%, the type of indoor unit is
limited and the maximum number of indoor unit is reduced.
††† These values, measured in anechoic chamber, at a point 1 m in
front of the unit at a height of 1.4 m. During actual operation,
these values are normally somewhat higher as a result of ambient
conditions.
