 The number of connected indoor units is 4 and the maximum number of connected indoor units on the 120 model
outdoor unit is 8, 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 120 and the CI of the 120 model outdoor unit is 123, so the combination ratio is
120 / 123 = 97.5%.
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.
