Installing, inspecting and replacing the air-cleaning filter
1. Open the air inlet panel and remove the air filters. Page 26
2. Remove the filter holders, with the air-cleaning filter installed in the folders, from the
air-conditioner.
3. Remove the allergen clear filter (Light orange) from filter holder and inspect the
filter. Use a vacuum cleaner to remove any dust or dirt from the allergen clear filter.
Replace the allergen clear filter if it cannot be cleaned or if it has been for about 1
year.
(The allergen clear filter should be replaced after about 1 year of use. However, the
actual replacement period may vary depending on the conditions in which the filter
is used.)
Remove the photocatalytic washable deodorizing filter (orange) from the filter
holder and inspect the filter. Periodically, remove any dust or dirt from the photo-
catalytic washable deodorizing filter. If the photocatalytic washable deodorizing fil-
ter is particularly dirty, it may be washed with water. However, the filter is fragile so
be sure to wash it installed in the filter holder to avoid damaging it. After washing
the filter, place it in sunlight to dry. Placing the filter in sunlight revitalizes the deo-
dorizing effect.
(Do not dispose of the filter holders. They are reusable. )
4. Install the air-cleaning filter in the filter holders, and then install the filter
holders in the air-conditioner.
5. Install the air filters and close the air inlet panel.
