mode the air quality status lights may display bad air quality
even if the air quality is good. If this occurs, select Manual
mode under these conditions.
2. If the unit is unplugged and has not been used for a
long period of time, then switched on in Auto mode, the
air quality status lights may display bad air quality even
if the air quality is good. This may be due to pollutants on
the surface of the sensor. If this occurs, clean the sensor as
instructed on page 20.
The air outlet cover opens to
90 degrees in auto, manual and
fast sterilise modes.
The air outlet cover opens to 45
degree when the unit is in night

Repair and Maintenance
1. Preliminary lter: The cleaning frequency of this lter is
determined by the operating speeds of the fan, the level
of air pollution and total unit operational time. Under
normal circumstances it should be cleaned every 12 months
minimum, but where operational hours are high or in dirty
atmospheres, it may need to be cleaned every 3-6 months.
Air sterilisation eciency is reduced if the lter is not
cleaned regularly.
2. HEPA & activated carbon lters: The average service life
of the these lters is approximately 12 months. This may
be reduced in environments with higher than average air
pollution or where the unit is used for longer than normal
operational hours. The lters should be replaced every 12
months minimum, or sooner if the lter icons on the display
panel ashes. When the icons turn constant red, the lters
must be replaced immediately to retain the unit’s sterilising
eciency.
3. Cleaning of preliminary lter:
1) Turn o and unplug the unit.
2) Pull the top edge of the rear cover away from the unit and
then lift the cover up to remove it.
3) Rotate the two retaining sliders at the top of the unit 90
degrees in the direction of the arrows and lift out the lter
assembly, using the handle.

assembly frame on both sides and bottom rst, then rotate
the lter upwards to remove top tabs from the frame.
5) Method of cleaning: gently use a brush or a vacuum
cleaner with hand held nozzle to remove the dust. If the
lter is excessively dirty, it may be cleaned with water and
detergent. Ensure that the lter is fully dried before re-
installing it into the assembly and air purier. Take care not
to bend the lter during cleaning, to avoid damage.
6) Reinstallation method:
Reverse the removal
instructions Firstly insert top
tabs into sockets at top of the
frame, rotate lter downwards
and relocate side and bottom
tabs into corresponding
sockets. The lter pullers must
