Cleaning the Lamp Housing Screens
In dirty or dusty environments, the two dust filter screens in the lamp hous-
ing can become clogged, causing high temperatures and premature lamp
failure. Routine maintenance to remove dust from the screens lowers the
lamp operating temperature and prolongs lamp life. To maximize lamp life
you should clean the screen at least every 250 hours, and sooner in
extremely dirty or dusty environments.
