Removing The Light Engine Intake Duct; Removing The Lamps - Christie M Series Service Manual

Removing the light engine intake duct

The light engine intake duct allows air to flow to the light engine. The duct sits over top of intake fan
#5 on the outer most side of the upper portion of the light engine cover. Air flows from outside the
projector through the filter (if used) into the duct and the fan brings the air into the engine housing.
Estimated replacement time: 8 minutes.

One screw holds the duct to the top of the light engine cover the other two screws are located
at the bottom of the projector and hold the duct to the base plate.
