Possible solution
Check if the packing material is removed from the filter.
•
The filter has not been placed in the appliance. Make sure
•
that the filter (FY1700/30) is properly installed.
The particle sensor is wet. The humidity level in your room
•
is high and causes condensation. Make sure that the
particle sensor is clean and dry (see the chapter "Cleaning
and maintenance").
Room size is large or the outdoor air quality is poor.
•
For optimum purification performance, please close the
doors and windows when operating the air purifier.
There are indoor pollution resources. For instances,
•
smoking, cooking, incense, perfume or alcohol.
Filter reaches the end of life. Replace the filter with a new
•
one�
The particle sensor is dirty. Clean the particle sensor (see
•
the chapter "Cleaning and maintenance").
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 even if removing filters, 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 gases. It's
recommended that you reactivate the filter by putting it in
direct sunlight for repeated use. If odor still exists, replace
the filter.
It's normal if the appliance runs at the Turbo mode.
•
In the Auto mode, if the appliance is too loud, maybe the
•
appliance runs at high speed because air quality becomes
worse, or your personalized setting in App triggers a
higher fan speed. You can choose the Sleep mode, or
change the settings in the App.
If there is abnormal sound, contact the Consumer Care
•
Center in your country.
If anything drops into air outlet, it may also cause
•
abnormal loud sound. Immediate turn off appliance, turn
appliance upside down, to get foreign objectives out of
appliance�
