Cleaning and Replacing the Air Filter 5 Follow this procedure in reverse to install a new air filter. • Handle the air filter carefully. If damaged, the air filter will not work properly. • When the lamp is replaced, it is recommend that you also clean or replace the air filter. • Contact the Canon Customer Support Center for further information. • Replacement air filter part number: RS-FL02 • This can also be purchased from the Canon website. Cleaning the Air Filter The air filter protects the lens and mirror inside the projector from dust and dirt. Should the air filter become clogged with dust, the projector may be damaged since it will block the air flow into the projector and raise the internal temperature of the projector. The following screen is displayed when turning on the projector if the air filter needs to be cleaned (after approx. 300 hours). Clean the air filter if it is displayed. • Only the [ ], [ ], OK and POWER buttons are available while this screen is displayed. (When you press the POWER button, the "Push POWER button again to turn off power." message appears.) • When this screen has disappeared after being displayed for 10 seconds, all buttons become operable. • Turn the power of the projector off and pull out the power plug. • Hook your finger around the air filter handle on the front of the projector and remove the air filter. Use a vacuum cleaner to clean off the dust. • If the air filter cleaning screen is displayed when turning on the projector after cleaning the air filter, select [Yes] and press the OK button. The air filter cleaning screen will disappear. • This screen is not displayed when [Air filter warning display] is set to [Off]. (P157) Do not rinse the air filter in water, which may damage the air filter and projector. 200
