Christie CP4315-RGB Replacing page 4

To keep out dust and other contaminant, Christie recommends covering the LOS opening with
a lint-free cloth.
Replacing the diffuser
Follow these steps to replace the diffuser.
Notice. If not avoided, the following could result in property damage.
• Always wear clean, powder-free latex gloves when handling optical components.
1. Set the rear IOS on a table and separate the integrator from the coupling elbow.
a) Remove the four screws (a in the image in step b) from the rear of the integrator rod
assembly.
b) Separate the elbow (b in the image below) and set it aside.
2. Lay the integrator assembly on a table and remove the static diffuser.
a) Remove the four silver screws (a in the image in step c)—short with washers.
b) Lift off the retaining clip (b in the image in step c).
c) Lift the static diffuser (c in the image in step c) out of the retaining pocket.
Note the rectangular diffusion area in the center that looks like frosted glass.
3. Inspect the integrator rod for any damage, contamination, and for signs of misalignment
towards the spinning diffuser.
If signs of misalignment are seen, the integrator rod assembly may need to be replaced. The
centered appearance of the rectangular shape of the integrator entrance aperture in the image
below is a good indicator the integrator rod has not "walked".
