the lamp compartment and dispose of cleaning materials. Wash hands 
after lamp replacement. This product has a lamp which contains a very

impact lamp performance and operating life. Routine maintenance to 
remove dust and dirt from the screens lowers the lamp operating tempera
-
ture and prolongs lamp life. To maximize lamp life you will need to clean 
the screens every 250 hours. Lamp screen maintenance may need to occur 
more often than 250 hours depending on your installation/use environ
