The illustration in this explanation shows how to clean the air filters on the top panel.
Clean the other filters in the same way as these air filters (small type).
1
Remove the air filter.
Turn the 2 screws counterclockwise until they are disen-
gaged, then lift the air filter a little to remove it.
- The screws do not come off.
- The number of screws differs depending on the air
filter.
2
Remove the metal filter.
Note: The metal filter does not come off the small type
air filters.
See “For small type air filters” on the next page.
(1) Turn the air filter upside down.

Slowly bend the metal filter a little to unlatch the three
catches from the grooves in the panel one by one.
Note: Bending the metal filter too much could dam-
age it beyond repair. Be very careful to only bend the
metal filters a little when removing them.

Remove the metal filter from the panel.

Use a vacuum cleaner to remove the dust.
Use a vacuum cleaner to remove the dust from both
sides of the metal filter, the projector and the panel.
Note: Do not wash the metal filter in water. Doing so will
cause the dust to clog the holes, reducing intake
performance.
