1. Open the front panel. (page 26.)
2. Remove the air filter.
• Press the claws on the right and left of the air
filter down slightly, then pull upward.
3. Take off the Titanium Apatite
Photocatalytic Air-Purifying Filter.
• Hold the tabs of the frame, and remove the
claws in 4 places.
4. Clean or replace each filter.
See figure.
5. Set the air filter and Titanium Apatite
Photocatalytic Air-Purifying Filter as
they were and close the front panel.
• Operation without air filters may result in
troubles as dust will accumulate inside the
indoor unit.
Air Filter
1. Wash the air filters with water or clean them with
vacuum cleaner.
• If the dust does not come off easily, wash them with neutral
detergent thinned with lukewarm water, then dry them up in the
shade.
• It is recommended to clean the air filters every 2 weeks.
Titanium Apatite Photocatalytic
Air-Purifying Filter
The Titanium Apatite Photocatalytic Air-Purifying Filter can be renewed by washing it with water
once every 6 months. We recommend replacing it once every 3 years.
[ Maintenance ]
1. Vacuum dusts, and soak in warm water or water for about 10 to 15
minutes if dirt is heavy.
2. Do not remove filter from frame when washing with water.
3. After washing, shake off remaining water and dry in the shade.
4.
Since the material is made out of paper, do not wring out the filter when removing water from it.
[ Replacement ]
1. Remove the tabs on the filter frame and replace with a new filter.
• Dispose of the old filter as flammable waste.
