USAGE

Starting Use

Step 1: Position the Air Humidifier

1. Place the air humidifier on a stable, horizontal, and level surface to prevent vibrations and noise. Never move the air humidifier during use.
2. Set up the air humidifier with at least 30 cm of clearance on all sides.
3. Make sure that the air inlet (10) and air outlet (3) are never blocked.

Step 2: Fill the Water Tank

1. Remove the motor unit (4) by lifting it upwards.
2. Insert the filter (5) into the water tank (9) using the filter holder (8), including the water level sensor (6).
3. Fill the water tank (9) up to the “Max.” mark (7) with cold tap water or distilled water. The water temperature must not exceed 40°C. Do not fill the water tank above the “Max.” mark.
4. Place the motor unit (4) back onto the water tank (9).

Step 3: Allow the Filter to Become Saturated

To ensure optimum humidification performance, allow the filter (5) to absorb water for 30 minutes before switching on the air humidifier. The water level may fall below the “Max.” mark (7) during this process.

Step 4: Switch On the Air Humidifier

1. Insert the mains plug into a suitable socket. Ensure that the cable does not pose a tripping hazard.
2. Press the ON/OFF button (11) to switch on the air humidifier. During initial use, the air humidifier will operate in Auto mode (A) by default (see section “7.3 Setting the Fan Speed/Mode”).
3. The LED light ring (2) switches on automatically. It displays the current room humidity using different colours (see section “7.5 LED Light Ring”). After a few seconds, the current relative humidity appears on the display (12).
4. When the water tank becomes empty, the air humidifier switches off automatically, and the water tank indicator (21) lights up on the control panel. No humidity values are displayed when the tank is empty. Refill the water tank (9) or activate the filter drying function if required (see section “8.1 Filter Drying Function”).

Step 5: Set Additional Functions

You can optionally adjust the target humidity, fan speed/mode, timer function, and LED light ring. For more information about these functions, refer to sections 7.2 to 7.5.

Step 6: After Use

1. Disconnect the mains plug from the socket after each use.
2. Empty any remaining water from the water tank (9). Do not leave water in the tank when the device is not in use.
3. Allow the filter (5) to air dry when not in use, or use the filter drying function periodically after use (see section “8.1 Filter Drying Function”).

Setting Target Humidity

If desired, you can set a target humidity level on the air humidifier. The target humidity indicator (13) displays the selected humidity level (40%, 50%, or 60%). If no value is illuminated, the humidifier continues operating until the humidity reaches 70%, then switches off automatically. To prevent excessive humidity, a target level between 40% and 60% is recommended.

1. Press the target humidity button (14) to select your desired humidity level.
2. The selected humidity level lights up on the target humidity indicator (13). If no value lights up, the target humidity is set to 70%. Once the selected humidity level is reached, the air humidifier switches off automatically.

Setting the Fan Speed/Mode

The air humidifier features three fan speeds (1, 2, and 3) and two operating modes: AUTO mode (A) and NIGHT mode (SL).

- With the air humidifier switched on, press the fan speed button (16) to select the desired fan speed or operating mode. The selected setting appears on the display (12). After a few seconds, the display returns to showing the current relative humidity of the room.

Timer Function

The air humidifier has a timer function that allows you to set how many hours the device should operate before switching off automatically. The timer can be adjusted between 1 and 9 hours.

1. Press the timer button (15) to select the desired operating time. The selected timer setting appears on the display (12), for example, “5 h”. After a few seconds, the display returns to showing the current room humidity.
2. To deactivate the timer, press the timer button (15) repeatedly until “0 h” appears on the display. The timer is now switched off.

CLEANING AND MAINTENANCE

8.1 Filter Drying Function

Mould and bacteria can develop in the filter (5) when the air humidifier is not in use. Therefore, always empty the remaining water from the tank and dry all components when the device is not being used. Allow the filter (5) to air dry naturally or use the filter drying function for faster drying.

1. Before activating the filter drying function, ensure that all remaining water has been emptied from the tank. Any residual moisture underneath the filter holder (8) must be dried manually. The filter drying function can only be started once the residual water has been removed.
2. Press and hold the fan speed button (16) for 5 seconds to activate the filter drying function. The filter drying indicator (19) lights up, and the filter (5) is dried at the highest fan setting for 3 hours. To stop the drying function before completion, press any other button.
3. Once the drying cycle is complete, check that the filter (5) is completely dry. If moisture remains, activate the filter drying function again.

Cleaning the Filter

Before cleaning, always ensure that the air humidifier is disconnected from the mains power supply. Only clean the filter (5) using the method described in these instructions. Never wash the filter in a washing machine or dishwasher. Regular filter cleaning is necessary to maintain hygienic and trouble-free operation. Rinse the filter (5) under running water once a week to remove accumulated dust, dirt, and hair.

Changing the Filter

When replacing the filter (5), only use original Beurer replacement filters (see section “9. Accessories and Replacement Parts”). Replace the filter (5) at least every 6 months. After 1440 operating hours, the filter change indicator (20) lights up automatically. If the filter becomes heavily soiled, deformed, or discoloured before reaching 1440 operating hours, replace it earlier and reset the operating hours counter to zero as described in step 6.

• Disconnect the air humidifier from the mains socket.

• Remove the motor unit (4) by lifting it upwards.

• Remove the old filter (5) and dispose of it properly.

• Place the new filter onto the filter holder (8). Ensure that the round hole of the filter holder fits onto the small projection at the bottom of the water tank.

• Place the motor unit (4) back onto the water tank (9). Make sure there is no gap between the two components.

• Switch on the air humidifier using the ON/OFF button (11). Press and hold the timer button (15) for 5 seconds until the filter change indicator (20) goes out. The internal operating hours counter is now reset to zero.

Cleaning the Motor Unit Housing

Clean the housing of the motor unit (4) using a slightly damp cloth with water or a mild cleaning solution. Do not use solvents, alcohol, or aggressive cleaning and scrubbing agents, as these may damage the surface. Never clean the motor unit (4) in a dishwasher. Ensure that no liquid enters the air outlet (3).

Cleaning the Water Tank, Filter Holder, and Water Level Sensor

The water tank (9), filter holder (8), and water level sensor (6) can occasionally be cleaned in a dishwasher. These components must not be exposed to temperatures above 45°C. The water level sensor (6) can be removed from the filter holder (8) by gently pulling it out. To reassemble, insert the sensor back into the filter holder. Alternatively, the water tank, filter holder, and water level sensor can be cleaned manually using a mild cleaning solution.

Descaling

It is recommended to descale the filter (5) and water tank (9) once a week. Prepare a descaling solution by dissolving 6 g of pure citric acid powder in 1 litre of water.

Descaling the Filter

1. Fill a suitable container with the prepared descaling solution.
2. Place the filter holder (8), including the water level sensor (6) and filter (5), into the solution. Ensure that all components are completely submerged.
3. Leave the components in the solution for 1 hour. Afterwards, rinse everything thoroughly under running water. Never squeeze the filter (5), as this may deform it.
4. Repeat the procedure if necessary.

Descaling the Water Tank

1. Fill the water tank (9) with the prepared descaling solution up to the “Max.” mark (7).
2. Allow the solution to remain in the tank for 1 hour.
3. Rinse the water tank (9) thoroughly with running water.
4. Repeat the procedure if necessary.

Storage

When the air humidifier is not in use, the following storage precautions are recommended:

1. Empty any remaining water from the water tank (9).
2. Dry the filter (5) using the filter drying function (see section “8.1 Filter Drying Function”) or allow it to air dry naturally.
3. Clean the filter (5), water tank (9), filter holder (8), and water level sensor (6).
4. Store the air humidifier in its original packaging in a clean, dry environment.
5. Ensure that no heavy objects are placed on top of the air humidifier during storage.
