Epson Projector Powerlite 5000 User Manual

							Cleaning the Air Filter
Clean the air filter at the bottom of the projector after every 100 hours
of use. If it is not cleaned periodically, it can become clogged with
dust, preventing proper ventilation. This can cause overheating and
damage the projector. To clean the air filter, follow these steps:1.Turn off the projector and unplug the power cable.
2.Turn the projector on its right side so that the handle is on top
and you can access the filter easily.
Note: Standing the projector with the handle at the top keeps dust
from getting inside the projector housing.
3.Use a screwdriver, coin, or similar object to unscrew one screw,
lift, and remove the filter cover.
Cleaning the Air Filter 
						

							4.The filter is attached to the inside of the filter cover. It is
recommended that you use a small vacuum cleaner designed for
computers and other office equipment to clean the filter. If you
don’t have one, use a dry, lint-free cloth.
If the dirt is difficult to remove or if the filter is torn, replace it.
