Christie M Series Service Manual page 51

Fog filters should be replaced after each use of the projector to a maximum of 20 hours. The life of the
filter is approximately 20 hours based on environmental conditions. Leave the filters in their sealed
packaging until ready for use.
The fog filters cannot be re-used or they clog up with oil and the projector overheats and shuts down.
Each filter is a two-stage filter; the black activated charcoal layer faces out, and the white layer faces
the projector.
1. Loosen the two captive screws at the top of each filter door.
2. Slide the filter out.
3. Insert the new filter with the white layer facing into the projector and the black layer facing
out.
4. Secure the filter door by tightening the two captive screws loosened in step 1.
