Cleaning the Intake
and Exhaust Vents
This CL-410/CL-420 is equipped with
intake and exhaust vents to allow the flow of
cool air through the projector and maintain
the proper operating temperature.
You should periodically clean the vents by
vacuuming them with a vacuum cleaner.
Runco recommends doing this after every
100 hours of use, or more often if the
projector is used in a dirty or smoky
location.
To clean the intake and exhaust vents:
1. Press OFF on the remote control to
turn off the power. Wait until the cooling
fan stops.
2. Unplug the power cord.
3. Remove dust by placing the cleaner
hose on the intake and exhaust vents.

Lamp Maintenance
The projector lamp has a life of 2,000 hours. Maintain proper ventilation to keep the lamp
operating throughout its lifetime. Do not subject the projector to unnecessary vibration.
• Lamp replacement is recommended after approximately 2,000 cumulative hours of use
or when you notice a significant deterioration in the picture and color quality. To find out
how long the currently-installed lamp has been in service, select
Information from the
Image Options menu.
• The actual lamp service life may be less than 2,000 hours depending on the
environment in which the projector is used.
• For lamp replacement, please contact your nearest Runco authorized service
center or Runco dealer. Do not attempt to replace the lamp yourself!
