Adjusting the air quality sensor sensitivity

People with certain health problems (e.g. allergies or asthma) have a

greater need for healthy air. For this reason, the air cleaner allows you to

adjust the sensitivity of the air quality sensor. When it is set to a higher

sensitivity level, the appliance already starts cleaning the air at lower pollution levels to make the air even cleaner.

There are 3 sensitivity levels: -- extra sensitive

-- sensitive -- standard

The air quality sensor is set to standard sensitivity.You can adjust the

sensitivity of the air quality sensor in the following way:

1	If the appliance is already plugged in, unplug the appliance and wait
	for a few minutes.
2	Press and hold the TIMER button and simultaneously put the mains
	plug in the wall socket.
,,	The appliance beeps twice and one of the HOUR lights flashes to
	show the current sensitivity level of the air quality sensor.
Sensitivity level:
HOUR light	Sensitivity level
1hr	extra sensitive
4hrs	sensitive
8hrs	standard
3	Press the TIMER button to adjust the sensitivity level of the air
	quality sensor.
,,	One of the HOUR lights flashes to show the set sensitivity level of
	the air quality sensor.
4	Press and hold the on/off button to switch off the appliance.
