Air filter cleaning

The air filter prevents dust and debris from getting inside the projector. Never run the pro- jector with the filter removed. It is recommended that the air filter is cleaned regularly.

•The message “Check the air filter for dirt.” is displayed every 100 hours. (If the usage time exceeds 100 hours, this message is displayed for about 30 seconds when the image is displayed for the first time after power is turned on. This display will be dismissed with any operation.)

•Check out the filter and any debris is found, use the following procedure for cleaning.

WARNING

•Request cleaning and maintenance of a ceiling-mounted unit from your sales representative.

Unplug power cord.

Remove the air filter.

Pull out the air filter by holding the release knob with your fingers as shown in the figure.

3 Clean the filter.

Carefully remove the dust and dirt from the air filter with a vacuum cleaner or the like.

4 Replace the air filter.

Insert the air filter firmly until you hear a click.

Notes

•When dirt and dust build up in the air filter, the air circulation inside the projector is affected and the internal temperature will rise, causing the projector to stop working or malfunction.

•Push the air filter fully in. If the projector is used with the air filter only partially inserted, dust and dirt will enter the interior and this could cause the projector to stop working or break down.

•If you wash the air filer with water, make sure to dry it completely before replacing it.

•If the air filter becomes damaged, replace it. Contact your sales representative for a new filter. If you continue to use the projector when its filter is damaged, dust and dirt will enter the interior and this could cause the projector to stop working or break down.
