Connect the power cord and press the start button (9).
Your appliance will be preset to automatic mode the first time you turn it on.
Thanks to its infrared particles sensor and its gas sensor (model PU6025 only), it detects the level of pollution in
the room and automatically adjusts the filtration speed accordingly.
A light changes color to indicate the quality of air in the room.
Setting the pollution sensors
The appliance is preset to medium sensitivity.
If the air quality indicator remains:
- poor after 2 hours in operation although the air seems to be purified
- excellent for more than 1 hour although the air seems to be polluted
you can adjust the sensor sensitivity as follows:
1. When the air purifier is off, hold down the filtration speed setting button for 2 seconds:
2. Set the sensitivity by briefly pressing the filtration speed setting button:
• Select high sensitivity if the air purifier indicates excellent air quality for more than 1 hour although the air
seems to be polluted.
• Select low sensitivity if the air purifier continues to indicate poor air quality even though it has been operating
for more than 2 hours and the air seems sufficiently purified.
3. The new setting is applied if no button is pressed for 10 seconds.
Start
Briefly press this button to switch the air purifier on or off.
Mode/filtration speed selection
Automatic: In this operating mode, the filtration speed automatically adjusts according to the air quality
detected by the particles sensor and the gas sensor (model PU6025 only). This mode is recommended for general
use.
Night: The filtration speed of your appliance is adjusted for a whisper quiet air flow during the night. The
light intensity of the appliance is also reduced. If pollution is detected, the filtration speed increases slightly to
purify your air but remains quiet to avoid disturbing your sleep.
Manual: In this operating mode, you can manually select 1 of the 4 filtration speeds.
