* The outdoor fan speed mentioned above depends on the compressor frequency.
(When the compressor frequency increases, the outdoor fan speed also changes to the higher
speed. When the compressor frequency decreases, the outdoor fan speed also changes to the
lower speed.)
* After the defrost control is operated on the heating mode, the fan speed keeps at the higher speed
as Table 9 without relating to the compressor frequency.
