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, keep a minimum clearance of 50 cm (20 inches) around the projector and never block or cover
the vents.
When replacing fans, ensure you confirm the fan direction for airflow. The correct orientation of the
fan will also ensure that the fan harness reaches the connector.

Inspect and clean the airflow interlocks to remove accumulated dust or dirt that could impede
movement.
Check: Every 6 months
