 The number of connected indoor units is 5 and the maximum number of connected indoor units on the 9HP outdoor
unit is 12, so the number of connected indoor units is within the limitation.
 Calculate the corrected capacity of the outdoor unit:
a) The sum of the indoor unit CIs is 314 and the CI of the 9HP outdoor unit (MVi-260WV2RN1(A)) is 260, so the
combination ratio is 314 / 260 = 121%.
b) Using the outdoor unit’s cooling capacity table, interpolate to obtain the capacity (“B”) corrected for outdoor air
temperature, indoor air temperature, and combination ratio. Refer to Tables 1-5.6 and 1-5.7.
