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 tempera-
ture and prolongs lamp life. To maximize lamp life you will need to clean
the filters every 100 hours. Dust filter maintenance may need to occur more
often than 100 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 38.
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.
