Cleaning the lamp filter screen
In dirty or dusty environments, the dust filter screen on the lamp module 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 screen lowers the lamp operating temperature and prolongs lamp life. To maximize lamp life you will need to clean the screen every 250 hours. Lamp screen maintenance may need to occur more often than 250 hours depending on your installa- tion/use environment.
1Remove the lamp module. Refer to page 19 for instructions.
2Examine the dust filter screen on the side of the lamp module. If neces- sary, use compressed or canned air to clean the screen. Then use a cotton swab dipped in isopropyl alcohol to lightly wipe the screen. After you've wiped the screen, blow away any remaining contaminants.
3Replace the lamp module and lamp door.
