*The outdoor fan speed mentioned adove 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 10 without relating to the compressor frequency.
