Replacing a Rotating Litho or Effect

1.Carefully handling the litho/effect by its edges only, orient it as shown when you replace it:

a.Rotating litho wheel: “Litho Installation Instructions” on page 6-9.

b.Rotating effects wheel: Orient the textured side of the effect away from the lamp. If the effect does not have a texture (e.g., the frost filter, orientation is not important).

2.If the litho/effect you are installing or replacing has an aperture ring, put the aperture ring on top of the litho. See Figure 6-10.

Litho	Aperture	Spring
(first)	ring (next)	(last)

Figure 6-10. An aperture ring, if required, must be placed on top of the litho/ effect and under the spring.

3.Carefully replace the spring, turning it as you compress it, until the spring is fully seated in the litho holder. Make sure the spring fits completely under all wheel tabs and that the tip of the spring does not protrude from under the tabs. See Figure 6-11:

Figure 6-11. When you replace a rotating litho or rotating effect, make sure the tip of the spring is fully seated under the wheel tabs; it cannot protrude from under the tabs.

4.You are finished. Replace the access door shown in Figure 6-1 on page 6-3 unless there are other dichroics, lithos or effects you want to replace.
