SiBE12-713 Instruction
Operation Manual 175
1. Open the front panel.
2. Pull out the air filters.
• Push upwards the tab at the center of each air
filter, then pull it down.
3. Take off the air purifying filter,
photocatalytic deodorizing filter.
• Hold the recessed parts of the frame and
unhook the four claws.
4. Clean or replace each filter.
See figure.
5. Set the air filter, air purifying filter
and photocatalytic deodorizing filter as
they were and close the front panel.
• Insert claws of the filters into slots of the front panel.
• Push the panel at the 5 points.
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 deter-
gent thinned with lukewarm water, then dry them up in the shade.
• It is recommended to clean the air filters every two weeks.
Air Purifying Filter (green)
(Replace approximately once every 3 months.)
1. Detach the filter element and attach a new one.
• Insert with the green side up.
• It is recommended to replace the air purifying filter every three months.
Photocatalytic Deodorizing Filter (gray)
[ Maintenance ]
1. Dry the photocatalytic deodorizing filter in the sun.
•
After removing the dust with a vacuum cleaner, place the filter in the sun for approximately 6 hours.
By drying the photocatalytic deodorizing filter in the sun, its deodorizing and antibacterial
capabilities are regenerated.
• Because the filter material is paper, it can not be cleaned with water.
• It is recommended dry the filter once every 6 months.
[ Replacement ]
1. Detach the filter element and attach a new one.
