Combination Ratio Restrictions
e.g. Outdoor unit 38VMA240RDS5-1(6-1) has 240 as the capacity index.
It is recommended to keep a proper combination ratio for the entire system.
Table 17 —Combination Ratio
NOTES:
1. When 40VMH048, 054, 072, 096---3 is installed.
2. When outside air processing units (40VMA) and standard indoor units are connected, the total capacity index of the 40VMA must
be limited to 30% or less of the capacity index of the outdoor unit. When 40VMA and 40VMZ indoor units are connected with
no additional indoor units, the 30% rule does not apply.
