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

adequate airflow, follow the requirements specified in the line drawing (P/N: 020-001480-XX) and
never block or cover the vents.

fan also ensures that the fan harness reaches the connector.
