Ventilation and cooling
Vents and louvers provide ventilation, both for intake and exhaust, keeping the projector
components within their operating temperature specifications.
Do not install the projector near a radiator, heat register, or within an enclosure. To ensure
adequate airflow, follow the requirements specified in the line drawing (P/N: XXX-XXXXXX-XX) and
never block or cover the vents.
When replacing fans, ensure you confirm the fan direction for airflow. The correct orientation of the
fan also ensures that the fan harness reaches the connector.
Replacing fans 1, 2, and 3
The fans 1, 2, or 3 draw the hot air out of the projector and provides exhaust cooling for the light
engine and electronics.
