Cleaning/changing air filters
To make sure that your projector operates safely and effi-
ciently, you should change or replace the filters after every
250 hours of operation. It is best to change or clean all of the
filters at one time. To clean the filters, wash them in a solu-
tion of warm, soapy water.
Your Polaview Model 305 Projector has three air filters.
