About White Dust Use of high mineral content hard water may cause a white mineral residue to accumulate on surfaces in the room near the humidifier. The mineral residue is commonly called "white dust." The higher the mineral content (or, the harder your water is), the greater the potential for white dust. The white dust is not caused by a defect in the humidifier. It is caused only by minerals suspended in the water. How and Why To Use Demineralization Cartridges: The HoMedics demineralization cartridge will help reduce the potential for white dust, a deposit of minerals left behind from using hard water in your humidifier. The cartridge should be replaced every 30 - 40 fillings. The cartridge may need to be replaced more often if you are using very hard water. Replace the cartridge when you notice an increase in white dust build-up. If white dust still forms around the humidifier after a new cartridge has been installed, consider using distilled water. To purchase new demineralization cartridges, model # HUMHDDC4-6CTM, go back to the retailer (where you purchased your humidifier), or visit www.homedics.com If you live in an area with hard water, or use a water softener, we recommend using distilled water for better results from your humidifier. Never use water softening additives in your humidifier. Fig.11 Fig.12 Installing Instructions 1. Remove demineralization cartridge from packaging and let it soak in water for 10 minutes. 2. Remove the oscillation nozzle.

Place the oscillating nozzle back on to the unit and lock into place by turning the ring to the right until the locator icon is aligned with the LOCK position. (Fig.10) Note: The demineralization cartridge has no top or bottom. Either side can face upward. Cleaning and Care CAUTION: Before cleaning the unit, turn power off and unplug unit from the outlet. To Clean the Water Tank: Remove the tank from the humidifier base by lifting it from the main unit. Unscrew the tank cap and rinse inside the tank with clean water. To remove any scale or build-up, use a 50/50 Fig.13 mixture of vinegar and lukewarm water to clean the inside of the tank. Suggestion: Clean the water tank once every two to three weeks, depending on your water conditions. To Clean the Ultrasonic Membrane: Fig.14 Put a small amount of mild dish soap on the surface of the ultrasonic membrane, then pour in some water and let soak for five minutes. Brush clean with a soft-bristle brush (not included) and rinse. Suggestion: Clean the membrane once every Fig.15 two to three weeks, depending on your water conditions. NOTE: Never submerge the base in water or any liquid. To Clean the Outer Surfaces: Clean the surface of your humidifier with a clean, Fig.16 damp, soft cloth as often as needed. 11
