Recommendation
Should the air filter become clogged with dust particles, it will reduce the cooling fan's
effectiveness and may result in internal heat build up and short lamp life. We
recommend cleaning the air filter after the projection lamp is replaced.
Refer to "Air Filter Cleaning".
WARNING
• For continued safety, replace with a lamp assembly of the same type.
