3.) Power connection

Insert the plug into the socket and wait for the LED indicator to light up briefly.

4.) Switching the air purifier on or off

Press the ON / OFF switch. The air purifier acknowledges the command with a short beep, the operating light stops

flashing, the LED display switches on and the air purifier starts its operation. The default operating mode is air

sensor mode (Auto mode).

To switch off, press the ON / OFF switch for approx. three seconds. The air purifier acknowledges the switch-off

with a short beep and the LED display switches off.

5.) Setting the different operating levels or the auto mode

Manual operation:

Press the "FAN SPEED" button and select your desired power level by pressing it repeatedly. There are three air

circulation levels:

 Night mode (Silent) > Particularly quiet operation with very low air circulation.

 Weak fan stage

 Powerful fan stage

(See chart below).

Night mode

Weak fan stage

Powerful fan stage

Auto mode

Auto mode:

Press the "FAN SPEED" button until the Auto mode indicator lights up in the display panel. The air sensor then

switches on and automatically starts measuring the air quality.

(See above chart).

Please note that the proper air sensor function is only available after approx. two minutes !

If the determined air quality is "good", the air purifier automatically switches to a weak fan stage. If the result is the

opposite and the air quality is inferior or poor, the air purifier switches to a strong fan stage.

Notes on the air sensor

The air sensor is located in a small compartment on the side and reacts to particles in the air and thus always gives

only a tendency of the air quality. Since it is a tendency (similar to a weather station), this function cannot provide a

100% reliable statement about pollutants in the room air or about the entire area of a room.

Furthermore, stronger operating fluctuations may occur from time to time (jump from red to green and vice versa),

as the air sensor probe reacts to particles and volatile organic compounds (VOCs) in the room and is also exposed

to draughts.

Cleaning the air sensor

To ensure trouble-free operation of the air sensor (Auto mode), we recommend cleaning the air sensor

approximately every two months. First take a soft brush to clean the air slots above and below the air sensor.
