Ventilation And Cooling; Replacing The Light Engine Intake Fans (#1, 2, 3, 4) - Christie Crimson Series Service Manual

Ventilation and cooling

Vents and louvers provide ventilation, both for intake and exhaust, keeping the projector components
within their operating temperature specifications.
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.
