Air Filter Maintenance
●
Wash the air filters with water if small dust particles remain on the air filters even after automatic filter cleaning is per-
formed.
●
It is recommended to perform dust box maintenance when the air filter maintenance is performed.
1. Open the front panel, and then remove
the dust boxes and air filters.
Refer to procedure 1 in Dust Box Maintenance (page 19).
2. Remove the air filters from the dust boxes.
Refer to procedure 1 in Dust Box Maintenance (page 19).
3. Remove the dust with a vacuum cleaner,
and then wash the air filters with water.
●
Wipe the air filters with a towel, etc., after washing
them with water, and then place them in a shaded area
to dry.
●
Do not bend the air filters. The air filters may be dam-
aged and prevent the automatic filter cleaning from
being performed. Be especially careful not to damage
the teeth of the rack on the back of each air filter.

ter cleaning stops during filter cleaning or the air fil-
ters do not come out, etc.), remove the dust boxes
and air filters and install them again.
