and smaller than the capacity index at 100% combination ratio of each outdoor unit. Up to 8~16 indoor units
can be connected to one outdoor unit. It is recommended to choose a larger outdoor unit if the installation
space is large enough.
If the combination ratio is greater than 100%, the indoor unit selection shall be reviewed by using actual
capacity of each indoor unit.

Use OUTDOOR UNIT CAPACITY TABLES.
Determine correct table according to the outdoor unit model and combination ratio.
Enter the table at given indoor and outdoor temperature and find the outdoor unit capacity and power input.
The individual indoor unit capacity (power input) can by calculated as follows.
IUC=OUC × INX/TNX
Where,
IUC: Each indoor unit capacity
OUC: Outdoors unit capacity
INX: Each indoor unit capacity index
TNX: Total capacity index
Then, correct the indoor unit capacity according to the piping length.
If the corrected capacity is smaller than the load, the size of indoor unit has to be increased and repeat the
same selection procedure.
