Removing The Integrator Assembly; Removing The Fold Mirror - Christie M Series Service Manual

11. Remove the shutter.
The wire for the shutter is thin and fragile. It can easily get caught and pinched between the
upper and lower engine housing during disassembly and assembly. Make sure the wire is not
pinched during reassembly.
12. To re-install, follow these steps in reverse order.

Removing the integrator assembly

The assembly connects to the front optical housing which is a hard casting. The integrator is sealed
and can be adjusted by two adjustment screws, one for the horizontal and one for the vertical. Light
enters from the side of the integrator and is directed at the angle of incidence for total internal
reflection to occur.
Estimated replacement time: 53 minutes.
Caution! If not avoided, the following could result in minor or moderate injury.
• Always wear clean, lint-free gloves when handling the product.
Each lamp has one integrator. One integrator is shorter because the light travels a shorter distance.
