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 AUTO operating mode.

“AUTO” OPERATING MODE

After switching on, the appliance is in AUTO operating mode. The desired relative humidity level (rH) is pre-set to 50% in AUTO 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  AUTO operating mode, the rH can be modified at any time using the button. If the performance level is modified using the button, the AUTO operating mode switches off automatically, and the appliance is in manual operating mode.

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

The longer the appliance is operated, the more the performance of the A7017 Ionic Silver Stick ® 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 quality, 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 A7417 “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 canresult 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.

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

6. Clean the BONECO U250 with a dish brush.
   

CLEANING THE MEMBRANE

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.
