Connecting Multiple Capacity Indoor Units
When diff erent capacity units need to be connected, it is recommend to connect
the one has highest capacity at the bottom and the smallest unit at the top of the
ODU refrigerant connection manifold. For example, if the system has one 9K, 18K,
and 24K Indoor units, the 24K indoor unit should be connected via the port A. and
the 9K indoor unit should be connected via the port C. (See Fig. 11)
