Cleaning the dust filters

In dirty or dusty environments, the dust filters can become clogged, causing high temperatures inside the lamp module. These high temperatures can impact lamp performance and operating life. Routine maintenance to remove dust and dirt from the filters lowers the lamp operating temperature and prolongs lamp life. To maximize lamp life you will need to clean the filters every 250 hours. Lamp filter maintenance may need to occur more often than 250 hours depending on your installation/use environment.

There are two filters, one mesh filter attached to the dust filter door and one metal grid filter adjacent to the lamp door.

1 Turn off the projector and unplug the power cable.

2 Wait 60 minutes to allow the projector to cool thoroughly.

WARNING: To avoid burns, allow the projector to cool for at least 60 minutes before you clean or replace the dust filter.

3 Turn the projector upside down and remove the lamp door. See page 23. 4 Remove the dust filter door.

5 Clean the filter using a vacuum set on low power.

6 Replace the dust filter door and the lamp door.

7 Vacuum the non-removable metal grid filter adjacent to the lamp door.
