( Table7 : Outdoor fan speed )
* 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

lower speed.)
* After the defrost control is operated on the heating mode, the fan speed keeps at the higher speed
as table8 without relating to the compressor frequency.
