Replacing the unit
Filter
If dirt does not come off even after the air filter unit is maintained, it is time for the unit to be replaced.
The Replacement Filter Unit (Model No.: ET
-

EMF330) is an optional accessory. To purchase the product, consult 
your dealer.
Attention
 f Make sure to turn of f the power before replacing the filter. (x pages 58, 68) fMake sure that the projector is stable, and perform the maintenance in a safe place even if the filter falls accidentally .
Note
 fThe replacement cycle of the air filter unit varies greatly depending on the usage environment.
For the air filter unit
The section describes the replacement procedure of the standard air filter unit attached to the projector .
This air filter unit is the same as the Replacement Filter Unit (Model No.: ET
-

EMF330) (accessory/optional 
accessory).
1)
 
Remove the air filter unit.
 f Refer to “Removing the air filter unit” ( x
