THE RIGHT LOCATION

THE RIGHT LOCATION

The BONECO appliance 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 appliance directly on the floor, since the moisture from the mist can damage floor surfaces such as parquet or delicate carpeting.
Make sure that the appliance stands about one foot (30 centimeters) away from the closest wall.
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 appliance 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

After the unit is switched on, it is in AUTO-Mode. The desired relative humidity (rH) is preset to 50%. The unit chooses the appropriate output level Low "L" / Medium "M" / High "H", in order to attain the value of 50% rH as quickly as possible.
In AUTO-Mode, the rH can be changed at any time by using button . If the output level is changed by using button , the AUTO-Mode turns off and the unit is operated manually.
The heater can be switched on or off without the appliance leaving AUTO mode. AUTO mode also remains active when setting the timer.
To return to AUTO mode, tap the symbol once.

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 appliance 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 appliance.
Never add the aromatic substance directly into the water tank or water base; doing so will damage the BONECO appliance 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 appliance 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 appliance 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 appliance.
2. Select the desired settings.
3. Tap the symbol multiple times until the desired run time is displayed.
   Now the BONECO appliance will run for the specified time and then switch off.
4. To deactivate the OFF timer early, switch the BONECO appliance off and back on as needed.

SETTING THE ON TIMER

1. Switch off the BONECO appliance.
2. Tap the symbol multiple times until the desired standby time is displayed.
   The BONECO appliance switches on after the defined time and operates with the selected settings.
3. To deactivate the ON timer early, switch the BONECO appliance off and back on as needed.

CLEANING AND MAINTENANCE

CARE INSTRUCTIONS

With time and use, the performance of the A250 decreases and scale builds up on the inner parts of the BONECO appliance. 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.

CLEANING AND DESCALING

DESCALING

If stubborn limescale deposits form at the bottom of the BONECO appliance, the appliance must also be descaled in addition to the cleaning. For this process, use the provided "EZCal" descaling agent. You can get replacement parts at your BONECO specialist dealer or at the online store under www.shop. boneco.us

1. Disconnect the BONECO appliance from the power outlet.
   The unit must always be unplugged from the power outlet before draining it. Failure to do so can result in electric shock and pose the risk of severe or fatal injury!
2. Empty the water tank.
   
   Tip the long side of the BONECO appliance towards the sink (with the viewing window facing down). This prevents water from getting into the air outlet and damaging the unit.
   
3. Remove the A250.
4. Mix 1 bag of EZCal with 32 oz. (1 liter) 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.
   
7. Rinse the inside of the water tank with fresh tap water.
8. Reinsert the A250.

REMOVING MINERAL DEPOSITS

Mineral deposits on the membrane can be removed using the yellow cleaning brush attached to the cover of the BONECO appliance.

Never clean the membrane using sharp objects or aggressive cleaning agents; doing so can damage the BONECO appliance 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.

ON THE A250

PREPARING THE A250

Please observe the accompanying manual for starting up the A250.

ON WATER HARDNESS

The BONECO U250 is supplied with the A250. 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, making it necessary to replace the A250 earlier.
Dispose of the saturated A250 with your regular household waste.
White dust around the appliance is a sure indication that the A250 is fully worn out.

REPLACING THE A250

The A250 must be replaced every 2 to 6 months. In cases of very hard water, it may have to be replaced sooner. White dust around the appliance is a sure indication that the A250 is fully worn out.
Please observe the accompanying manual for starting up the A250.
The used A250 can be disposed of with your regular household waste.
