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 humidier 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. Remove top housing by rotating (2) lock wheels and lifting up top

housing. Remove nozzle by rotating it counterclockwise and lifting up. 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 humidier 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 humidier 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. If minerals remain in the metal (stainless steel) boiler cup, a metal

scraper can be used to scrape o 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 humidier 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 humidier.

8. Each day the reservoirs and tanks should be drained, rinsed and relled 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 sucient time to dry before plugging the

electrical cord into the outlet.

10. If it is noticed that the accumulated residue on the oat switch aects the oating

action, clean carefully with a soft brush.

11. After base is totally cleaned and dried, replace mineral absorption pad. Place nozzle

on base and rotate clockwise until it locks. Place Top Housing on Main Housing

and rotate lock wheels until it locks in place.

12. Replace tanks. Plug in the unit and resume normal use.
