8-1-8. Outdoor Fan Control (DC Fan Motor)
Although the outdoor fan motor drives the outdoor fan by non-step variable system of the revolution speed, the
revolution speed is restricted to three steps on the convenience of controlling. If a strong wind is lashing outside
of the room, the operation may be continued as the outdoor fan stops in order to protect the outdoor fan motor.
If a fan lock occurred due to entering of foreign matter, the air conditioner stops and an alarm is displayed.
