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 tanks from humidifier base, and drain water from tanks.
3. Allow at least 15 minutes for the hot water to cool after shutting unit “OFF” before
moving base. Rotate steam diffuser counterclockwise until steam diffuser slots line
up with tabs in base, and lift up. Rotate steam dome until steam dome slots line
up with tabs in base and lift out. 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.
WARNING:
DO NOT place directly under running faucet.
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
and from the two metal water level probes (they appear like two metal wires)
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. If minerals remain in the
metal (stainless steel) boiler cup, a metal scraper can be used to scrape off the
mineral deposits. Be careful not to use any metal blade on any plastic parts.
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 tanks using a solution of one teaspoon of household chlorine
bleach in 1 gallon of water. Let the solution sit for 20 minutes, swishing every few
minutes to wet all surfaces. Empty the tanks completely; rinse thoroughly until all
of the bleach smell is gone. Fill the tanks with fresh, cool water and replace them
onto the humidifier base.
7. NEVER use any metal or hard objects to clean plastic parts which may cause
scratching of the plastic parts. The only exception to this is the metal part of the
hot water reservoir. A metal scraper can be used to clean this part only. 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 reservoirs and tanks should be drained, rinsed and refilled with fresh
tap water.
9. To clean exterior surfaces, use a solution of water and mild detergent with a wrung-
out damp cloth. Rinse and wring out the cloth and wipe the exterior surfaces again.
Finally, wipe with a dry cloth. Allow sufficient time to dry before plugging the
electrical cord into the outlet.
10. After base is totally cleaned and dried, replace mineral absorption pad. Place steam
dome on base by aligning its slots with tabs in base. (You may have to reposition
steam dome to other set of tabs, because it will only fit one way.) Rotate steam
dome clockwise until it locks. Place steam diffuser on base so that the slots in
steam diffuser line up with tabs on the base. Rotate steam diffuser clockwise until it
locks in place.
11. Replace tanks. Plug in the unit and resume normal use.
