Vicks Germ-Free V790 Instructions Manual page 7

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 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 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. If it is noticed that the accumulated residue on the float switch affects the
floating action, clean carefully with a soft brush.
