STARTING UP AND SWITCHING OFF

HUMIDITY AND ULTRASONIC

SAVING SETTINGS
The BONECO U250 saves the last-used settings when it is switched off. However, if the appliance is disconnected from the power outlet for a few seconds, it will start in the
operating mode.

“AUTO” OPERATING MODE
After switching on, the appliance is in operating mode. The desired relative humidity level (rH) is pre-set to 50% in operating mode. The appliance selects the
suitable performance level Low “L” / Medium “M” / High “H” to reach the rH value of 50% as soon as possible.

In operating mode, the rH can be modified at any time using the button. If the performance level is modified using the button, the operating mode switches off automatically, and the appliance is in manual operating mode.

The heater can be switched on or off without the appliance exiting operating mode. the operating mode also remains active when setting the timer.

To return to operating 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 display starts flashing
2. While the display is flashing, tap the symbol again until the desired humidity is set.

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

CONTROLLING OUTPUT

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:

FRAGRANCE CONTAINER

BASICS
Commercially available fragrances and essential oils can be inserted into the fragrance container on the rear side.

Never mix any additives into the water base itself, since doing so can decrease the performance of the BONECO appliance and even cause damage. This damage is not covered by the warranty.

USE

1. Press down on the fragrance container to take out the drawer.
   

2. Sprinkle the felt insert in the drawer with the fragrance of your choice.
   

3. Reinsert the fragrance container.

The fragrance container can be cleaned in the dishwasher. The temperature may not exceed 50 °C.

NOTES ON CARE

CARE INSTRUCTIONS
With time and use, the performance of the A250 decreases and scale builds up on the inner parts of the BONECO U250. 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 appliance from the power outlet before cleaning.

DESCALING AND CLEANING

ON DESCALING
If stubborn limescale deposits form at the bottom of the BONECO U250, the appliance must also be descaled in addition to the cleaning. For this process, use the provided
EZ-Cal “CalcOff” descaling agent. You can obtain a refill of the agent from your BONECO specialist dealer.

The appliance 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!

Do not let water get into the ventilation opening! This will damage the appliance.

DESCALING THE APPLIANCE

1. Disconnect the BONECO U250 from the power outlet.
   

2. Drain the water base.
   

3. Mix the EZCal with approx. 0.5 liters (17 oz) of water and pour the mixture into the humidification chamber.
   

4. Wait 30 minutes to allow the solution to take effect.

Clean the BONECO U250 with a dish brush.

DESCALING AND CLEANING

CLEANING THE MEMBRANE
Never clean the membrane using sharp objects or aggressive cleaning agents; doing so can damage the BONECO U250 and void the warranty!

Mineral deposits on the membrane can be removed using the yellow cleaning brush attached inside the base of the BONECO U250.

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.

REPLACEMENT
You can obtain replacements from your BONECO specialist dealer or our online store at www.boneco.us.
