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 from the electrical outlet.
2.Place the projector on its side with the handle at the top so that the filter is easily accessible.
Note: Placing the projector in this position keeps dust from getting inside the projector housing.
3.Lift up the tab securing the air filter cover and remove the cover. (The air filter is attached to the inside of the cover.)
4.Use a small vacuum cleaner designed for computers or other office equipment to clean the filter. If you don’t have one, use a dry,
If the dirt is hard to remove or if the filter is torn, replace the air filter.
Note: An air filter comes with each replacement lamp (part number ELPLP07).
5.Replace the air filter cover.
6.Plug the power cable back into the electrical outlet.
Replacing the Lamp
The projector lamp typically lasts for about 2000 hours of use. It is time to replace the lamp when:
❏The projected image gets darker or starts to deteriorate
❏The projector lamp light is flashing orange and red alternately
❏The message LAMP REPLACE appears on the screen when the projector lamp comes on
Warning: Let the lamp cool before replacing it. Also, don’t touch the glass portion of the lamp assembly; this can cause premature lamp failure.
1.Turn off the projector and unplug the power cord from the electrical outlet and the projector. Wait at least 20 minutes for the bulb to cool.
2.Place the projector on its side with the handle on the top so you can easily access the lamp cover.
Note: Placing the projector in this position keeps dust from getting inside the projector housing.
3.Use a screwdriver, coin, or similar object to loosen the retaining screw on the lamp cover. When the screw is loose, lift off the lamp cover. (You cannot remove this screw from the cover.)
