Lens and main unit cleaning
WARNING
•
Request cleaning and maintenance of a ceiling-mounted unit from your
projector dealership. Attempting to clean the unit or replace the lamp in a high
location by yourself may cause you to fall, possibly resulting in injury.
Lens cleaning
•
Clean the lens with a commercially available blower

Main unit cleaning
•
Always unplug the power cord before cleaning the main
unit.
•
Wipe dirt off the main unit gently with a soft cloth.
•
Do not wipe the main unit with a damp cloth.
Doing so may allow water to get inside, resulting in
possible electric shock or unit failure.

Do not use benzene, thinner or other similar
chemical solutions as they may deform or discolor
the unit or damage the paint surface.
•
Do not use a chemically saturated cloth.

Cleaning the filters
The projector uses three filters to keep the fans free of dust and other particles, and should
be cleaned every 500 hours of operation. In dustier environments, it is recommended to
clean the filters more frequently. If the filter is dirty or clogged, your projector may overheat.
When the message below is displayed the filters must be cleaned.
Note
•
When the Please clean filter message is displayed, please clean or replace all three
filters at the same time to synchronize the hours used display. The Filter Warning item
should be enabled in the Setting 3 menu
Refer to the following guide to clean the filters.
Lift the projector to clean the filter located at
1
the bottom.
Note
•
Only clean the outside of the exhaust vents with a
vacuum cleaner.
The left-hand filter can be cleaned as shown in
the right figure.
The rear filter can be accessed as shown.
Once the filters are cleaned, please reset the
filter time using the Reset menu
Note
•
Using the projector without the air filters fitted inside allows dirt and dust into the
projector, causing failure.
WARNING
•
Request cleaning and maintenance of a ceiling-mounted unit from your projector
dealership. Attempting to clean the unit or replace the lamp in a high location by yourself
may cause you to fall, possibly resulting in injury.
