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 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.

1Turn off the projector and unplug the power cable.

2Wait 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.

3Turn the projector upside down and remove the lamp door. See page 32.

4Remove the dust filter door.

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

6Replace the dust filter door and the lamp door.

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

Using the security lock

The projector has a security lock for use with a cable lock system. See
