Fill Water Tank.

Turn off humidifier and unplug the power cord from A/C outlet. Remove tank from

base. Turn upside down and unscrew filling cap. Fill tank with clean, cool, distilled,

filtered, or tap water. Do not attempt to fill unit through Vapor Nozzle. Water temperature

should NEVER be too hot or too cold. Extreme temperatures can damage the

unit. Tighten filling cap firmly. Return tank to base and let it sit for a few minutes. For

first time use or when replacing the demineralization cartridge filter, please soak the

filter in warm water for several minutes.

Throw the unit out - it's garbage

I had the same problem. During the cleaning process, the white float was installed upside down and humidifier water level sensor was unable to read the float. I removed the phillips screw and inverted the float with the dark ring toward the bottm. Quick fix.

Buy a new filter cartridge. www.ventahumidifiers.com

Caring For Your Venta-Sonic Humidifier
IMPORTANT!
Always unplug the unit before cleaning!
When to Clean Your Humidifier

Clean your humidifier weekly or more often during heavy use, depending on your
individual water quality. Clean your humidifier before storing and after long periods
of storage.

When cleaning the inside of your unit, keep water away from the air outlet. Exterior
may be wiped with a damp cloth when unit is off and unplugged.
Cleaning the Oscillator and Water Sensor

Turn off the unit and unplug power cord. Remove tank from base and empty
reservoir in base. Use cleaning brush provided in base to clean off mineral deposits
and sediment from oscillator and water sensor. Do not scrape or clean with tools
that have metal parts. Be careful to not damage the surface of the oscillator.
ATTENTION: Damage to the oscillator may cause the unit to not work properly.

The oscillator (ultrasonic transducer) is highly sensitive. Keep this important part
clean and treat gently. Do not touch the oscillator while the unit is operating.

Do not use soap, cleaning agents, detergents, or other chemicals for cleaning the
tank and humidifier.

After cleaning fill water tank (see instructions above) and return tank to base.
Storing the Venta-Sonic
Switch off and unplug power cord from A/C outlet. Empty remaining water from base
and tank. Clean tank and unit (see for instructions above). Make sure all parts are
thoroughly dry—allow at least 24 hours to dry. Leave the filling cap of the tank
loosened. This will keep the cap and gasket from sticking together. Pack Venta-Sonic
in original packaging and store in a cool and dry place.
