REPLACING THE FILTER CARTRIDGE 

 Always power down and disconnect/disengage all power sources to the 

projector before servicing or cleaning.

 

Allow the projector to cool for at least 45 minutes before the lamp cover is 

opened. The inside of the projector can become very hot and may cause injury.

NOTE: 

To maintain normal internal ventilation replace the filter unit periodically. 

1. Use a vacuum cleaner to remove dust on and 

around the filter cover (Figure 3-Top-Left). 

2. Lift and pull the bottom clips to remove the filter 

cover (Figure 3-Top-Right).

3. Pinch and pull the filter clips to remove the filter 

unit (Figure 3-Bottom-Left). 

4. Use a vacuum cleaner to remove dust on and 

around the intake vents of the projector (Figure 3-
Bottom-Right). 

5. Install the new filter unit into the place. 
6. Install the filter cover.

NOTICES: 1) 

Make sure the filter cartridge is 

correctly inserted into the projector otherwise, the 
projector cannot be turned on. 

2)

 Do not block the air 

vents. Doing so may result in malfunction of the projector. 

3)

 When using the projector under dusty or 

smoky conditions, dust may accumulate on a lens, liquid crystal panels, or optical elements inside the 
projector. Such conditions may degrade the quality of the projected image. When the symptoms above 
are noticed, contact your authorized dealer or service station for proper cleaning.
