INTRODUCTION

Congratulations on your purchase of the BONECO U350. This high-performance ultrasonic humidifier keeps the humidity at a comfortable level at all times.
The BONECO U350 is designed for convenient, fully automated operation. However, you can adjust all of its features according to your preferences and requirements. This manual shows you how you can create your own comfortable climate.

VALUABLE INFORMATION ABOUT HUMIDITY
The right humidity is very important for our health. Dry room air in winter leads to skin that cracks and itches. It makes your eyes and throat feel dry while significantly affecting physical comfort. Not only does this affect adults, it is especially true for infants, small children and even pets. Dry mucous membranes in winter also make us more prone to colds and other infections.
The BONECO U350 makes these problems a distant memory. Its intelligent automatic controls always keep the humidity at the ideal level, even in large rooms with an area of up to 60 square meters (650 square feet).

You will not want to give up your newly gained comfort.

PREPARATION OF THE A250 AQUA PRO

DEMINERALIZATION CARTRIDGE PREPARATION

1. Remove the packaging of the BONECO A250 AQUA PRO.
2. Rinse the A250 AQUA PRO for 2 minutes under cold running water.
3. Screw the A250 AQUA PRO to the BONECO U350.

ON WATER HARDNESS
The BONECO U350 is supplied with an A250 AQUA PRO. The granulate contained in it filters the lime out of the tap water so that it is not released into the room air. Hard tap water accelerates saturation of the granulate so that the A250 AQUA PRO must be replaced earlier.
DETERMINING WATER HARDNESS

1. Dip the enclosed test strip into a glass of cold tap water for 1 second.
2. Read the water hardness after one minute.
3. Refer to the table to determine the duration of effect of the A250 AQUA PRO:

Dispose of the saturated A250 AQUA PRO with your regular household waste.
The A250 AQUA PRO should not be used longer than specified. White dust around the appliance is a sure indication that the A250 AQUA PRO has run its course. You can obtain replacements from your BONECO specialist dealer or our online store at www.shop.boneco.us.

STARTING UP AND SWITCHING OFF

THE RIGHT LOCATION

THE RIGHT LOCATION
The BONECO U350 releases more than half a liter of water into the air per hour. This makes it important to set up the appliance in the right location.
Do not place the BONECO U350 directly on the floor, since the moisture from the mist can damage floor surfaces such as parquet or delicate carpeting.

• Make sure that the unit stands about 1 ft (30 cm) away from the closest wall.
• The unit should be placed in an elevated position, e.g. on a table, chest of drawers, etc.
• Do not direct the mist toward the wall, plants, furniture or other objects in order to prevent water condensation from damaging them. Maintain a distance of at least 20 inches (50 cm).

HUMIDITY AND ULTRASONIC

SAVE SETTINGS
The BONECO U350 saves the last-used settings when it is switched off. However, if the appliance is disconnected from the power supply for a few seconds, it will start in the AUTO operating mode.
“AUTO” COMFORT MODE
In AUTO mode the humidification is controlled automatically and the humidity is set to 50%. As soon as the humidity or the ultrasonic is manually adjusted, however, the appliance leaves AUTO mode.
To return to AUTO mode, tap the symbol once. The heater can be switched on or off without the appliance leaving AUTO mode. AUTO mode also remains active when setting the timer.

CONTROLLING HUMIDITY
The humidity can be set between 30% and 70%. In the “Co” setting (for “Continuous”), the ultrasonic runs regardless of the measured humidity. This means it does not switch off until the tank is empty or the appliance is switched off.

1. Tap the symbol. The current humidity indicator starts flashing.
2. While the indicator is flashing, tap the symbol again until the desired humidity is set.

The value is applied after a few seconds. The indicator stops flashing.

REGULATING PERFORMANCE

1. Tap the symbol multiple times until the desired level appears on the display.

The symbol on the display indicates which of the three levels (low/medium/high) has been selected:

COMFORT FUNCTIONS

SWITCHING THE HEATER ON AND OFF
The BONECO U350 is equipped with a heater that can be turned on and off. It warms the outgoing mist up to approximately 95 °F (35 °C), so that the room temperature stays at a comfortable level.
It takes a few minutes until the heater reaches its full output.

1. Tap the symbol once to switch on or off the heater.

FRAGRANCE CONTAINER
Commercially available scented aromatic substances for humidifiers can be added to the fragrance container on the back of the BONECO U350.

Never add the aromatic substance directly into the water tank or water base; doing so will damage the BONECO U350 and void the warranty!

1. Press down on the fragrance container to unlock the drawer.
2. Sprinkle the cotton wadding in the drawer with the fragrance of your choice.

TIMER FUNCTIONS

The timer function lets you determine how long the BONECO U350 should run before it switches off automatically (OFF timer).
Alternatively, you can specify a time for when the appliance should switch on automatically (ON timer). For example, you can use this function to activate the BONECO U350 before you return home, so that when you get back you have the perfect home climate waiting for you.

SETTING THE OFF TIMER

1. Switch on the BONECO U350.

2. Select the desired settings.

3. Tap the symbol multiple times until the desired run time is displayed.
   Now the BONECO U350 will run for the specified time and then switch off.

4. To deactivate the OFF timer early, switch the BONECO U350 off and back on as needed.

SETTING THE ON TIMER

1. Switch off the BONECO U350.

2. Tap the symbol multiple times until the desired standby time is displayed.
   The BONECO U350 switches on after the defined time and operates with the selected settings.

3. To deactivate the ON timer early, switch the BONECO U350 off and back on as needed.

CLEANING AND MAINTENANCE

CARE INSTRUCTIONS
With time and use, the performance of the A250 AQUA PRO decreases and scale builds up on the inner parts of the BONECO U350. Stagnant water can also impair cleanliness and lead to unpleasant odors. This means regular maintenance and cleaning is necessary to ensure clean and unimpaired operation.

Recommended cleaning and maintenance intervals vary depending on air and water quality, and operating time.
Use a soft, damp cloth to clean the exterior.
Always unplug the unit from the power outlet before cleaning.

DESCALING

DESCALING THE APPLIANCE

1. Switch off the BONECO U350.
2. Empty the water base and the water tank.
3. Take out the A250 AQUA PRO.
4. Mix 1 bag of EZCal with 32 oz. (0.5 liters) of water and pour the mixture into the water tank, one half to the left and right each.
5. Wait 30 minutes to allow the solution to take effect.
6. Rinse the water tank with tap water. Remove remaining lime residue, if any, using a scrub brush.

CLEANING THE MEMBRANE
Stubborn limescale residue on the membrane can be removed using the yellow cleaning brush stored inside the BONECO U350. Never clean the membrane using sharp objects or aggressive cleaning agents; doing so can damage the BONECO U350 and voids the warranty!

CLEARING THE CLEANING MESSAGE
After completion of cleaning, delete the message by pressing the button and holding it for 2 seconds.
