■ Problem

■ Symptom

Function Code: FL (also applicable: NO, CO, HI, LO, F1~F6, ㄱ, ㄴ, etc.)

■ Cause

The "FL" code on a mobile or portable air conditioner indicates that the condensate water tank is full.

This typically occurs in high-humidity conditions, where the base pan fills up with water. In such cases, the "FL" or “CH04” code will appear on the display.

■ Solution: How to Drain the Condensate Water

Follow these steps to resolve the issue:

1. Turn off the appliance and disconnect the power cord from the outlet.

2. Place a large bucket or container under the drainage nozzle located at the bottom of the unit.

3. Open the drainage cap and allow all the water to drain completely.

4. Once the water has fully drained, close the cap securely.

■ Important Safety Precautions

• Do not tilt the appliance excessively while draining, as this may cause water to overflow.

• Always empty the water before moving the appliance.
  Failure to do so can result in water leakage, leading to electric shock, fire, or property damage.
