Cleaning The Lamp Housing Screens - InFocus LP 240 User Manual

Cleaning the lamp housing screens

In dirty or dusty environments, the dust filter screens in the lamp housing
area in the LP250 can become clogged, causing high temperatures and pre-
mature lamp failure (these screens are not present on the LP240). Routine
maintenance to remove dust from the screens lowers the lamp operating
temperature and prolongs lamp life. To maximize lamp life you may want
to clean the screen every 250 hours.
1
Remove the lamp module.
2 Examine the dust filter screens in the lamp housing area. If necessary,
use a vacuum cleaner set on low power to clean the screens. Be careful
not to disturb any internal components when cleaning the screens.
3
Replace the lamp module and lamp door.
