REMEDY
• Check the fi lters. If they appear to be extremely dirty, clean or replace them. (Ref.
E-15)
• The air may have been dirty when the unit was plugged in. Unplug the unit, wait
one minute, and then plug the unit in again.
• Dirty or clogged dust(sensitive) sensor openings interfere with sensor operation.
Gently clean the sensor fi lter or the back panel. (Ref. E-13).
• The unit may make clicking or ticking sounds when it is generating ions.
• Check to see if the fi lters are extremely dirty.
• Clean or replace the fi lters. (Ref. E-13, E-14, E-15)
• Use only fresh tap water. Using other water sources risks the growth of mold,
fungi, or bacteria.
• Make sure the unit is installed in a location in which the sensors can detect cig-
arette smoke.
• Check to see if the dust(sensitive) sensor openings are blocked or clogged. If
they are blocked or clogged, clean the sensor fi lter or the back panel.
(Ref. E-13)
• Whenever after performing maintenance or replacing the fi lters, connect the
power cord to an outlet and then press the Filter Reset Button. (Ref. E-13)
• When Light control is set to "Auto", the light automatically turns off when the
room is dark. Moreover, when Light control is set to "Turn off", the light is always
off. If you do not want the light to be off, set Light control to the "Darker" setting.
(Ref. E-11)
• The room has reached the appropriate level of humidity and has stopped hu-
midifying.
• Check the styrofoam fl oat for impurities. Clean the Humidifying Tray. Make sure
that the unit is on a level surface. (Ref. E-14)
• Check to see if the Humidifying Tray and Water Tank are correctly installed.
Check the Humidifying Filter. (Ref. E-14)
• If the fi lter is extremely dirty, clean or replace it. (Ref. E-15)
• The Cleanliness Monitor automatically changes colour when the dust (sensitive)
sensor and odour sensor* detect impurities. If you are concerned about the
change, you can change sensor sensitivity.
(Ref. E-11,E-12) (*UA-HG60E / UA-HG50E)
• There is a difference in the humidity level within the same room.
• The sensor have different measurement parameters.
• If the monitor indicates wattage or temperature, switch the display by pressing
the DISPLAY SELECT button. (Ref. E-10)
• Outdoor and indoor as well as the home environment (the volume of traffi c near-
by, number of stories in home, etc.) may cause a reading different than local
PM2.5 data.
• The room is suitable for viruses to survive due to low room temperature. We
recommend you adjust the temperature using heating appliances. (Ref. E-9)
• The room temperature and humidity is high. We recommend that you drink
some water or lower the room temperature. (Ref. E-10)
If error occurs repeatedly, contact the Sharp Service Centre.
Make sure that the Humidifying Filter and Humidifying Tray are
properly installed, and then turn the power to ON again.
