Possible Solution

Does the Charcoal Filter need to be cleaned?

After 120 hours of fan operation, the display will show “C” when the fan is active. When this icon shows in the display, the charcoal filters should be washed. To reset the charcoal filter saturation alarm, press and hold FAN for 3 seconds. “C” will no longer be displayed.

The charcoal filter can be cleaned and reactivated. Clean the filter in the dishwasher using normal detergent and the highest temperature setting. To reactivate the filter, dry the filter in an oven for 10 minutes at a maximum temperature of 210°F (100°C).

If the charcoal filter is not used (vented mode), press and hold the “+” and “-” buttons at the same time for 3 seconds. “F” will appear in the display for 3 seconds. When the charcoal filter is not in use, the charcoal filter alarm is disabled.

NOTE: The charcoal filter should be replaced after approximately three years of use.
