Epson Powerlite 822p Multimedia Projector Users Guide

							Maintenance and Transportation71
To clean the air filter and air vent, follow these steps:
1. Turn off the projector, allow it to cool down, and unplug the 
power cord.
2. Turn the projector upside-down and clean the filter and air intake 
vent on the base of the projector.
To clean the filter and air vent, Epson recommends using a small 
vacuum cleaner designed for computers and other office 
equipment. If you don’t have one, gently clean them using a very 
soft brush (such as an artist’s brush).
If the dirt is difficult to remove or if the filter is torn, replace it. 
Contact your dealer or call Epson at (800) 463-7766 to obtain a 
new one (part number V13H134A13). 
3. If you need to replace the filter, slide it off, as shown.

is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The   lamp light is flashing orange. 
■The message Replace the Lamp appears on the screen when the 
lamp comes on. To maintain projector brightness and image 
quality, replace the lamp as soon as possible.
