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.

Caution

• 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

1Turn off the projector, remove the power plug from the AC outlet, and leave the projector stand for at least 1 hour.

2Remove the filter cover by pushing the latch.
