      When the room humidity is relatively high, the cooling or defrosting process in heating mode ends, the air outlet may release water mist. This is a normal physical phenomenon.

      If your GIWEE Air Conditioner doesn't blow air immediately after shutting down in cooling mode, the drying function may be enabled. Wait for it to finish, or use the remote to disable it. Also, the louver will close after 30 seconds.

      If your GIWEE Air Conditioner doesn't blow air when starting heating, it's preventing cold air from blowing until the indoor heat exchanger warms up. This usually takes 2 to 5 minutes.

      If your GIWEE Air Conditioner doesn't blow air for 6 to 12 minutes in heating mode, it might be defrosting automatically due to low outdoor temperature and high humidity. Please wait. Water or steam may come from the outdoor unit during defrosting.
