Ventilation And Cooling; Light Engine Fan Pack - Christie CP2420-Xe 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, 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 also ensures that the fan harness reaches the connector.

Light engine fan pack

The four fans of the light engine fan pack, which are mounted to a removable access panel frame, are
responsible for drawing air into the projector to cool the light engine and card cage components.
