Important! When the wick filter is replaced, the Filter Expire Indicator must also be reset. To reset your Filter Expire Indicator:
- Extra long-press the fan speed button for about 15 seconds until LEDs on the interface light up, then release.
- If done correctly, the wick filter replacement indicator will blink three times and then disappear.
