• The lter has not been placed in the appliance� Make sure that
the lter (FY4440/30) is properly installed�

smell� This is normal� However, if the appliance produces a burnt
smell even if removing lter, contact your Philips dealer or an
authorized Philips service center� The lter may produce smell
after being used for a while because of the absorption of indoor
gases� It’s recommended that you reactivate the lter by putting it
in direct sunlight for repeated use� If odor still exists, replace the
lter�
