2. Do not add water directly into the base chamber.
3. Do not add water through the mist tube.

• Replace the water tank cover.

Note: Make sure the nozzle on the water tank cover is placed over the mist tube, or the humidifier may not work correctly.

USING YOUR HUMIDIFIER

1. Plug in the humidifier. Rotate the Control Knob clockwise to turn the humidifier on. Adjust the knob to your desired mist level.
2. Rotate the nozzle to adjust the direction of the mist.
3. When your room has reached your preferred humidity level, turn the humidifier to a lower setting or turn it off.

Note: If there is no water in the tank or the tank is removed, the humidifier will stop misting, and the Refill Indicator Light will turn on. Refill the tank and properly place it on the base to use your humidifier.

Important Tips

Your humidifier must have the correct level of water in the base chamber to work properly. If there is too much water in the base chamber, the humidifier cannot create mist.

• Never pour water directly into the base chamber.
• Only add water to the water tank. The humidifier will automatically release the correct amount of water into the base chamber.
• Avoid moving or shaking the humidifier. This may cause the water tank to release too much water into the base chamber.
• Before moving the humidifier, turn it off, unplug it, and remove the water tank.
• If your humidifier doesn’t produce mist correctly, check the max water line to see if there is too much water in the base chamber. Pour out extra water if the water is over the max line.

Note: The max water line is only for this purpose. Do not pour water into the base chamber.

CARE & MAINTENANCE

Note:

• All maintenance should be done on a water­resistant surface, such as a kitchen counter.
• Change the water daily to avoid bacterial growth.
• Use a tissue or cloth to clean the nozzle regularly
• If not using the humidifier for 3 days or longer, do not leave water inside. Clean and dry the humidifier instead.

Cleaning

You should clean your humidifier every 3 days, and when you’re ready to store it.

Note:

• The water tank, cover, water filter and housing, mist tube, and float are dishwasher safe. Make sure the water temperature is below 158°F/70º C.
• Do not wash the base in the dishwasher, as the electronics will be damaged.
• Never immerse the base in water or liquid.
• Do not immerse the air outlet or air inlet in water.

1. Unplug the humidifier.
2. Remove the water tank cover.
3. Remove the water tank from the base and pour out any water from the tank and base chamber.
4. Remove the water filter and its housing from the tank by rotating counterclockwise and lifting out.
5. Remove the float from the base chamber by pulling up one end of the float and pulling the shaft out from the float brackets. One side of the float brackets is open (U-shaped) to allow the shaft to be removed.
6. Wash the tank, tank cover, water filter and housing, mist tube, and float with water and a mild detergent. Optionally, you can wash these parts in a dishwasher. Do not wash the base in the dishwasher.
7. Rinse the base chamber with room temperature water.
8. Dry all parts and reassemble.

Descaling Your Humidifier

1. Remove the water filter from the tank by rotating it counterclockwise and lifting it out.
2. Fill the tank with 3 US cups/ 710 ml of distilled white vinegar.
3. Replace the tank cover and swish the vinegar around the tank.
4. Place the tank on the base and soak for 15- 20 minutes. Vinegar will drain into the base chamber and loosen scale (mineral buildup) in the tank and in the base chamber (including the transducer and float).
5. Remove the tank, remove the tank cover, and pour out any vinegar.
6. Flip the tank over and remove the noise silencer. To remove the noise silencer, press the release tabs and gently pull away from the humidifier.
7. Remove the float from the base chamber by pulling up one end of the float and pulling the shaft out from the float brackets. One side of the float brackets is open (U-shaped) to allow the shaft to be removed.
8. Place the float, water filter assembly, and noise silencer in a small container. Fill with enough vinegar to cover them. Soak for 15-20 minutes.
9. Use the cleaning brush and a soft cloth to remove scale from all parts.
10. Rinse all parts until any vinegar smell is completely gone.
11. Dry all parts with a cloth. Make sure all parts are completely dry before reassembling or storing.

Storing

Follow the cleaning instructions (see page 6) and allow all parts to dry completely before storing. Store in a cool, dry location.

The Water Filter Assembly

The water filter prevents large particles from clogging the water outlet valve and entering the base chamber. Large particles in the water can cause leakage and polluted mist. We recommend that you clean or replace the water filter sponge regularly.

If the filter assembly is damaged or water cannot flow into the base chamber, the filter or filter assembly needs to be replaced. For more information, contact Customer Support.
