Replacing the Filters
It is recommended that the filters are cleaned after every 5000 hours of use and replaced after every 10000 hours of
use. These hours can vary depending on your usage environment.
There are two filters, one located at the front of the projector and one on the side.
Optional filters (two filter) are available.
Small one for the front
Large one for the left side
NOTE:
• Replace both filters with the new ones at the same time.
• Before replacing the filters, use a vacuum cleaner to vacuum dust and dirt from the vents (inlet) of the projector and use a dry
soft cloth to wipe dust off the cabinet.
• The projector contains high-precision parts. Keep out dust and dirt during filter replacement.
• Do not wash the filter with water. Water will damage the filter membrane.
• Attach the filter in the correct orientation. Failure to do so may cause dust and dirt to enter inside the projector, resulting in projec-
tor malfunction.
