Cleaning the dust filters
In dirty or dusty environments, the dust filters 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 filters lowers the lamp operating tempera-
ture and prolongs lamp life. To maximize lamp life you will need to clean
the filters every 250 hours. Lamp filter maintenance may need to occur more
often than 250 hours depending on your installation/use environment.
There are two filters, one mesh filter attached to the dust filter door and one
metal grid filter adjacent to the lamp door.
