Cleaning and Replacing the Air Filter
An air filter is installed in the air intake vent on the bottom of the main body to protect the
internal lens and mirror from dust. Should the air filter become clogged with dust, it will
block the air flow into the projector and causing an internal heat buildup which may cause
a problem.
• The main unit is very hot immediately after turning off the projector. Wait until
the projector cools down sufficiently before cleaning the air filter. You may get
burned or injured.
• Before cleaning or replacing the air filter, be sure to remove the power plug
from the AC outlet. Electric shock or fire may result.
• Do not insert any object into the projector through the air filter opening. You
may suffer electric shock or injury due to the high-voltage parts or rotating
parts.
Cleaning the Air Filter
Turn the projector upside down, remove the cover by pushing the latch, remove the air
filter, and clean it with a vacuum cleaner.
When cleaning dust off the side exhaust vent and the bottom air intake vent, bring the
vacuum cleaner nozzle close to them directly.
• Clean the air filter frequently.
• After cleaning the air filter, install it following the removal steps in reverse.
Procedure for Replacing the Air Filter
Turn off the projector, remove the power
plug from the AC outlet, and leave the
projector stand for at least 1 hour.
Remove the filter cover by pushing the
latch.
Remove the air filter.
Attach a new air filter under the filter cover.
Install the filter cover in place.
• Attach the lens cap when replacing the air filter.
• Handle the air filter carefully. If damaged, the air filter will not work properly.
• Replace the air filter whenever you replace the lamp.
• An air filter can be ordered from your Canon dealer.
