Frequently Asked Questions - Whisper Flex 2 DUUX
How do I clean the filter on my Duux Whisper Flex 2?
Turn off and unplug the unit. Open the filter cover (usually at the back or side). Remove the filter and vacuum or rinse with water. Let it dry completely before reinserting. Clean every 2 weeks for optimal performance.
Does the Whisper Flex 2 need a water tank to be emptied?
The unit has a self-evaporation system that recycles most of the condensate. However, if you use it in dehumidification mode or high humidity, you may need to empty the 0.8 L tank periodically. Check the indicator light.
What is the noise level of the Whisper Flex 2?
The noise level ranges from 25 dB(A) on low fan speed to 42 dB(A) on high speed. It is designed to be quiet, especially in sleep mode.
Can I use the Whisper Flex 2 as a heat pump in winter?
Yes, the Whisper Flex 2 has a heat pump function that provides heating with a capacity of 2.2 kW, effective down to about 5°C outdoor temperature. However, it is not intended as a primary heat source in very cold climates.
How do I set the timer on the Whisper Flex 2?
Press the Timer button on the remote or control panel. Use +/- to set the desired time (1-24 hours). The unit will turn on or off automatically after the set time. Confirm by pressing Timer again.
What does the error code 'E1' mean?
Error code E1 indicates a temperature sensor malfunction. Turn off the unit, unplug it for 10 minutes, and restart. If the error persists, contact Duux customer service.
Can I use an extension cord with the Whisper Flex 2?
It is not recommended to use an extension cord as it may cause voltage drop or overheating. Plug the unit directly into a grounded wall outlet. If necessary, use a heavy-duty cord rated at least 15A.
How do I drain the Whisper Flex 2 for storage?
Run the unit in fan-only mode for a few hours to dry out internal moisture. Then, remove the drain plug at the bottom (if any) to release any remaining water. Clean and dry the filter before storing in a dry place.
