Installing, inspecting and replacing the air-cleaning filter

1. Remove the air filter.
2. Remove the filter holders, with the air-cleaning filter installed in the holders, from
the air filter.
3. Remove the photocatalytic washable deodorizing filter (orange) from the filter holder
and inspect the filter. Periodically, remove any dust or dirt from the photocatalytic
washable deodorizing filter. If the photocatalytic washable deodorizing filter is par-
ticularly 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 deodorizing
effect.
Remove the natural enzyme filter (green) from the filter holder and inspect the filter.
Use a vacuum cleaner to remove any dust or dirt from the natural enzyme filter.
Replace the natural enzyme filter if it cannot be cleaned or if it has been used for
about 1 year.
(The natural enzyme 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.)
(Do not dispose of the filter holders. They are reused. )
4. Install the air-cleaning filter in the filter holders, and then install the filter holders
in the air filter.
NOTE
• The natural enzyme filter and the photocatalytic washable deodor-
izing filter may be installed on either the right or left side of the air
filter.
• Place the natural enzyme filter with the green side upper.
5. Install the air filter.
CAUTION
•
Do not expose natural enzyme filters to direct sunlight for an extended period. The bac-
teriolytic effect will be lost.
For replacement the air-cleaning filter, contact your dealer.
