1. Pour 2.5 cups (.6 liters) of undiluted distilled white vinegar into the Water Tank.
2. Replace Tank Cap and swish vinegar in Tank to coat the inside of the Water Tank.
3. Place Tank on Base, allowing vinegar to drain into the Water Reservoir. The vinegar will loosen
mineral buildup on the Nebulizer, Heating Element, Float, Chimney bottom, and in the bottom
of the Tank. Soak for 20 minutes.
4. Remove Water Tank and empty
vinegar into sink.
5. Remove Mist Chimney Cover,
Mist Chimney and Mist Outlet
to access Reservoir area (see
Disassembly instructions).
Use Cleaning Brush to loosen
mineral buildup in corners of Reservoir, Water Path and Boiling Chamber.
6. Gently wipe Nebulizer, Heating Element and Reservoir area with a soft cloth or paper towel to
remove loosened minerals.
NOTE: Nebulizer is fragile. DO NOT apply extreme pressure.
7. Pour vinegar from the Base into the sink. Be sure to pour from the side as indicated by an arrow to
avoid leaking into the Control Panel. Rinse the Tank and Reservoir with clean water until the smell
of vinegar is gone.
CAUTION: DO NOT SUBMERGE BASE IN WATER. DOING SO WILL DAMAGE THE
HUMIDIFIER AND VOID THE WARRANTY.
Reassemble Mist Chimney, Mist Chimney Cover, and Mist Outlet (see Reassembly instructions)
