Maintenance 59
Cleaning the Projector Case
Before you clean the case, turn off the projector and unplug the power cord.
■To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
■To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral
detergent. Then wipe the case and dry it with a dry cloth.
Caution: Never use wax, alcohol, benzene, thinner, or other chemical detergents. These
can damage the case. Do not use canned air, or the gases may leave a residue.
Cleaning and Replacing the Air Filter
Your projector includes an air filter to ensure the best performance. If dust collects on the air
filter, clean it as described below. Dust clogs prevent proper ventilation and cause overheating
and damage to the projector.
You can replace the air filter while the projector is mounted to the ceiling, if necessary. The
illustrations here show the projector placed on a table.
1. Press the Ppower button on the projector twice or the Standby button on the remote
control, wait for the power light to stop flashing, and turn off the power switch on the
back of the projector. The projector cools down.
2. Unplug the power cord.
3. Press in on the inner edge of the air filter cover to release the latch, then pull to remove
the cover.
