2. Capacity Range
Connected capacity ratio =
Total capacity index of the indoor units
Capacity index of the outdoor units
Keep a proper connected capacity ratio for the entire system.

NOTES
*1 When 40VMH048, 054, 072, 096---3 is installed.
*2 When outside air 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.
*3 When the total capacity of 40VMH048, 054, 072, 096---3 or 40VMV exceeds 30%, the combination must not exceeds 100%.
