2. Empty all the water from the unit. Siphon water out or soak it up
with a sponge.
3. Disconnect (or remove) the water tank.
4. Clean the surface of the transducer using distilled vinegar
and a soft, clean cloth.
This is very important. If the transducer is not kept clean, it
will fail. Using distilled or deionized water keeps the build-up to a
minimum, but cleaning with distilled vinegar cannot be ignored.
NOTE
Do not use any tools with metal parts or sharp edges to clean the
transducer. Scratching the transducer may cause fatal damage to
the unit.
5. To clean thick or heavy deposits, pour a small amount of vinegar
into the humidifier until the transducer surface is completely
covered. Let it stand for 30-60 minutes. Wipe clean with a soft
cloth. If further cleaning is needed, a soft, plastic bristle brush may
be used to gently clean the transducer surface.
6. Never leave water in the humidifier or water tank when the
humidifier is not in service.
Always empty all water and thoroughly dry all parts of the humidifier
when it is to be stored or taken out of service for any period longer
than one week. Do not seal the water tank in storage. Leave the
top off to allow the air to completely dry the tank. Any residual
moisture will encourage bacterial growth.
Never clean any parts of the humidifier with water above
120°°F.
