      Air Intake Vent Cleaning
Clean your projector when it is dirty or image projection is poor.  Clean the air 
intake vent every 100 hours in practice.
Warning:

Cleaning the Air Intake Vents
Accumulated dust in the air intake vents degrades ventilation, increases the 
interior temperature, and can cause malfunction.
To prevent debris from entering the air intake vents, always stand the projector 
upright with the lens upward.  Then use a vacuum cleaner or other equipment to 
suck dust from the vents.
Point:
If it is no longer possible to remove the dirt from the air intake vent, it is time to 
replace it. Consult your vendor.
