Do not place the humidifier directly on floors, carpets, or rugs.
Do not use other items as replacement parts for this product.
Do not cover the nozzle while the humidifier is on. Doing so may damage the humidifier.
Remove the water tank from the base before moving the humidifier.

If the humidifier is damaged or is not functioning properly, stop using it and contact Customer Support immediately (see page 2).
This humidifier is not to be used by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
Supervise children when they are near the humidifier.
Children should not clean or perform maintenance on the humidifier without supervision.
Children should be supervised to ensure that they do not play with the humidifier.

Household use only.

Caution: Risk of Leaks and Electric Shock

Do not add supplemental water treatment liquids into the water tank or base chamber. This will damage the humidifier and cause leaks.

Power & Cord

Ensure that the plug fits properly into a polarized socket.
Do not handle the power cord or plug with wet hands. Keep the plug and power cord away from liquids.
Your humidifier has a polarized plug (one prong is wider than the other), which fits into a polarized outlet only one way. This is a safety feature to reduce the risk of electric shock. If the plug does not fit, reverse the plug. If it still does not fit, do not use the plug in that outlet. Do not bypass this safety feature.
If the power supply cord is damaged, it must be replaced by Arovast Corporation or similarly qualified persons in order to avoid an electric or fire hazard. Please contact Customer Support (page 2).

Electromagnetic Fields (EMF)

This humidifier complies with all standards regarding electromagnetic fields (EMF). If handled properly and according to the instructions in this user manual, the appliance is safe to use based on scientific evidence available today.

GETTING STARTED

Remove all packaging.
Rinse and reassemble all parts before first use (see Cleaning, page 6).
Choose a hard, flat location for the humidifier at least 12 inches / 30 cm away from any walls.
Note:
Check to make sure that the water filter is correctly in place. If not, then rotate the filter clockwise to secure it in place. [Figure 1.1] Check to make sure that the float is securely in place. [Figure 1.2] The surface must be water-resistant. [Figure 1.3]
Mist should be directed away from walls,

furniture, bedding, and appliances. [Figure 1.4]

Filling & Refilling

Note: Make sure the water tank is clean before filling.

Turn the humidifier off.
Remove the water tank cover by holding the nozzle and pulling upward. [Figure 1.5]
Fill the tank with room-temperature water. [Figure 1.6] Note:
We recommend using purified or distilled water to fill the tank.
Do not fill past the tank’s max water line.
Do not fill with hot water.
CAUTION
Never add essential oils into the water tank or base chamber.
Do not add water directly into the base chamber. [Figure 1.7] Do not add water through the mist tube. [Figure 1.8]
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. [Figure 1.9]

USING YOUR HUMIDIFIER

Plug in the humidifier. Rotate the Control Knob clockwise to turn the humidifier on. Adjust the knob to your desired mist level. [Figure 2.1]
Rotate the nozzle to adjust the direction of the mist. [Figure 2.2]
When your room has reached your preferred humidity level, turn the humidifier to a lower setting, or turn it off.
Rotate the Control Knob counterclockwise to turn the humidifier 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. [Figure 2.3]
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. [Figure 2.4] 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 water is over the max line. [Figure 2.5]

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 bacteria 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 / 70°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.

Unplug the humidifier.
Remove the water tank cover.
Remove the water tank from the base and pour out any water from the tank and base chamber. [Figure 3.1] Note: When pouring out water, hold down the Cleaning (cont.)
float to ensure that it does not fall out of the base chamber.
Remove the water filter and its housing from the tank by rotating counterclockwise and lifting out.[Figure 3.2]
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.
Wash the tank, tank cover, water filter and housing, mist tube, and float with water and a mild detergent. [Figure 3.3] a. Optionally, you can wash these parts in a dishwasher. Do not wash the base in the dishwasher.
Rinse the base chamber with room-temperature water.
Note: Do not immerse the air outlet or air inlet in water.
Dry all parts and reassemble (see
Reassembling, page 7).
For detailed dishwasher cleaning instructions, contact Customer Support (see page 2).

Descaling Your Humidifier

Remove the water filter from the tank by rotating it counterclockwise and lifting it out. [Figure 3.4]
Fill the tank with 3 US cups / 710 mL of distilled white vinegar. [Figure 3.5]
Replace the tank cover and swish the vinegar around the tank. [Figure 3.6]
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). [Figure 3.7]
Remove the tank, remove the tank cover, and pour out any vinegar. [Figure 3.8]
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. [Figure 3.9]
Remove the float from the base chamber by pulling up one end of the float [Figure 3.10] 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. [Figure 3.11]
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. [Figure 3.12]
Use the cleaning brush and a soft cloth to remove scale from all parts.
Rinse all parts until any vinegar smell is completely gone. [Figure 3.13]
Dry all parts with a cloth. Make sure all parts are completely dry before reassembling or storing.

Reassembling

Flip the water tank over and place the noise silencer back into the tank. [Figure 3.14]
Place the water filter assembly back into the tank and rotate it clockwise to secure it in place. [Figure 3.15]
Place the float back into the base chamber:
a. Make sure the correct side of the float is facing up. [Figure 3.16] b. Insert the smaller prong into the closed side of the float brackets. [Figure 3.17] c. Place the larger prong into the open (U-shaped) side of the float brackets.
Refill the tank, if necessary.
Place the tank properly on the base and place the tank cover on the water tank.

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 (see page 2).
