Cleaning the Lamp Housing Screens
In dirty or dusty environments, the two dust filter screens in the lamp housing
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 depending upon
environmental conditions. The
dirtier or dustier the environment,
the more often you should clean
the screens.
