__________
Your DUET and the oscillator need to be cleaned.
Follow the steps on the previous page.
The DUET is a warm mist humidifier, not a steam
humidifier, so the mist will be warm but not hot.
Yes! Your DUET’s parts and their part numbers are
listed on page 2.
The cool mist setting is 81 degrees and the warm mist
setting is 104 degrees. Household temperatures can
sometimes aect this.
The white dust is a result of minerals naturally found in
your water. It can be cleaned easily with a dry cloth.
• Make sure you are not using a water softener in
your DUET.
• Install a new demineralization cartridge.
