A:Answer Hi there,
Thank you for your question. To answer that, this air conditioner has an internal tank to hold accumulated water from the condenser. Normally, this water is evaporated and exhausted to the outside. However, in periods of high humidity, the internal tank may become full. If this happens, “FL” will appear in the display, a tone will sound, and the air conditioner will turn off until the internal tank is emptied.
Here's the steps on how to empty the internal tank:
1. Turn off and unplug the air conditioner.
2. Place a pan or small bucket under the drain.
3. Remove the drain plug retainer by turning it counterclockwise.
4. Pull out the rubber drain plug.
5. Allow water to drain into pan or bucket.
6. Reinstall the rubber drain plug by pressing firmly into place.
7. Thread drain plug retainer clockwise onto drain, then tighten
hand tight.
