 The number of connected indoor units is 6 and the maximum number of connected indoor units on the 14HP outdoor
unit is 64, so the number of connected indoor units is within the limitation.
 Calculate the corrected capacity of the outdoor units:
a) The sum of the indoor unit CIs is 454 and the CI of the 14HP outdoor unit (MV6-R400WV2GN1) is 400, so the
combination ratio is 454 / 400 = 113.5%.
b) Using the outdoor units’ cooling capacity table, interpolate to obtain the capacity (“B”) corrected for outdoor air
temperature, indoor air temperature, and combination ratio. Refer to Tables 1-6.6 and 1-6.7.
