appliance. If you are unable to solve the problem with the information below, contact
the Consumer Care Center in your country.
Problem
Possible solution
The air purifier
does not work
even though it is
switched on.
•
Check if the top cover is properly installed.
•
The filter replacement indicator has been on continuously
but you have not replaced the corresponding filter, and the
air purifier is now locked. In this case, replace the filter and
reset the filter lifetime counter.
The airflow that
comes out of
the air outlet
is significantly
weaker than
before.
•
The pre-filter is dirty. Clean the pre-filter (see chapter
"Cleaning").
The air quality
does not improve,
even though the air
purifier has been
operating for a
long time.
•
Check if the packing material is removed from the filters.
•
One of the filters has not been placed in the air purifier
or a filter is not placed properly. Make sure that all filters
are properly installed in the following order, starting with
the innermost filter: 1) NanoProtect filter Series 3 (
FY5185
);
2) NanoProtect filter Active Carbon (
FY5182
); 3) pre-filter.
•
The air quality sensor is wet. Make sure that the air quality
sensor is clean and dry (see chapter "Cleaning").
The color of the air
quality light always
stays the same.
•
The air quality sensor is dirty. Clean the air quality sensor
(see chapter "Cleaning").
The air purifier
produces a
unpleasant smell.
•
The first few times you use the appliance, it may produce
a plastic smell. This is normal. However, if the appliance
produces a burnt smell, contact your Philips dealer
or an authorized Philips service center. The filter may
produce smell after being used for a while because of
the absorption of indoor air. Remove the filter and place
it where it has direct sunlight and ventilation for several
hours. Re-install and try using it again. If the odor remains,
please replace the filter.
The air purifier is
loud.
•
If the air purifier is too loud, change the fan speed to a
lower fan speed level. When using the air purifier in a
bedroom at night, choose the sleep mode.
