Cleaning Instructions

Failure to perform the necessary cleaning steps will damage unit.

1.Before cleaning, set CONTROLS to “OFF” position and unplug unit.

2.Remove water tank from humidifier base, and drain water from tank.

3.Allow at least 15 minutes for the hot water to cool after shutting unit “OFF” before moving base, or removing mineral absorption pad. Remove mineral absorption pad from hot water reservoir using tweezers or tongs to prevent burns from hot water. When the cleaning procedure is completed, replace mineral absorption pad. To drain water from humidifier base, grasp with both hands and tilt to the side, draining water into the sink. BE CAREFUL NOT TO HAVE DRAINING WATER FALL INTO CONTROLS OR VENT OPENINGS. DO NOT drain in any manner other than indicated. WARN- ING: DO NOT place directly under running faucet. Turn the base upside down and remove the cap by turning it counterclockwise. Clean out any for- eign matter that has accumulated inside the fitting from which the cap was removed. After cleaning, replace this cap tightly by hand. Pour a small amount of water into the hot water reservoir and check for leaks from this cap under the base.

4.Pour about 1 cup of white vinegar into either reservoir and allow it to soak for only 20 to 30 minutes.

5.Hold the base of the humidifier over the sink and tilt it on its side to empty the vinegar. Fill the cold and hot water reservoirs with clean, warm water to remove all traces of the vinegar. Remove any buildup of minerals in the hot water reservoir using a small brush, such as a toothbrush. NOTE: The buildup is due to water hardness. The harder your water, the more often this maintenance will be needed. Empty all of this water by turning the unit on its side.

DO NOT ALLOW WATER TO ENTER THE BOTTOM OF THE HUMIDIFIER BASE OR ANY OTHER OPENINGS, OR IMMERSE THE CORD AND PLUG.

6.Disinfect the water tank using a solution of one teaspoon of household chlo- rine bleach in 1 gallon of water. Let the solution sit for 20 minutes, swishing every few minutes to wet all surfaces. Empty the tank completely; rinse thoroughly until all of the bleach smell is gone. Fill the tank with fresh, cool water and replace it onto the humidifier base.

7.NEVER use any metal or hard objects to clean plastic parts which may cause scratching of the plastic parts. NEVER use gasoline, kerosene, glass cleaner, furniture polish, paint thinner or other household solvents to clean any part of the humidifier.

8.Each day the reservoir and tank should be drained, rinsed and refilled with fresh tap water.
