Ventilation And Cooling; Removing The Electronics Intake Fan (#2) - Christie M 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: 020-100192-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.

Removing the electronics intake fan (#2)

Fan #2 is located inside the filter bay on the outside of the card cage.
Estimated replacement time: 23 minutes.
1. Remove the top cover (on page 45).
2. Remove the card cage lid (on page 59).
3. Remove the bridge (on page 60).
4. Remove the card cage (on page 61).
5. Remove the panel driver (on page 62).
6. Remove the processor board (on page 88).
7. Remove the input cards from the rear of the card cage (on page 63).
8. Remove the fan by removing the four isolator pads in each corner.
To remove the fan, the card cage must be removed. The backs of the isolator pads are not
accessible after removing the card cage. Almost the entire inside of the card cage must be
removed to access them. Replacement isolator pads are part of the service kit.
The proper orientation of this fan is with the label on the fan hub facing inward towards the
card cage. An airflow indicator arrow on the fan must be pointing inward towards the card
cage.
