Note:
Capacity is factory set in the data IC on the PC board. A capacity setting adaptor that matches the capacity
of the unit is required in the following case.
If the indoor PC board installed at the factory is for some reason changed at the installation site, the
capacity will not be contained in the replacement PC board.
If you connect a capacity setting adaptor to a PC board in which the capacity is memorized, the capacity
setting for the PC board will become the capacity setting of the adaptor. (Priority of capacity setting
