Ventilation And Cooling; Replacing The Lamp Blower Fans (#1, 2, 3) - Christie Boxer 4K 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.
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: 020-000782-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.
