<Combinations of Connectable Indoor Units>
The combinations of the indoor units listed in Table 1 and Table 2 are combinations solely of those units which can be
operated concurrently. In addition to the combinations listed in the table, other combinations of indoor units are possible
provided that the following conditions are satisfied.
Conditions:
1.
At least two or more indoor units must be connected to the multi outdoor unit. It is not acceptable for only one indoor
unit to be connected.
2.
The total rated cooling capacity of the indoor units to be connected must be no more than 200% of the rated cooling
capacity of the outdoor unit.
Example: When 4 indoor units are connected
at 230V
If the following holds true
Rated cooling capacity of indoor units: K1, K2, ... (BTU/h)
Then:
It is therefore possible to connect 4 units with respective capacities of 7500 + 7500 + 7500 + 17500.
However, since this combination is not found in the 4-room operation column of Table 1, operating all these units concurrently
may result in trouble. At a time like this, shut down at least one of the 4 indoor units to match one of the combinations
found in the 3-room operation column of Table 1.
