5. Orient the new dichroic so that the coated side
of the dichroic is facing away from the lamp.
To determine which side of the dichroic is
coated, place the tip of a pen against each side
of the dichroic. Look at the dichroic and pen
from a slight angle.
On the coated side, the tip of the pen appears
to "touch" its reflection. On the uncoated side,
there appears to be a gap between the pen and
its reflection (see Figure 7-11).
6. Install the new dichroic in the color wheel by
pushing it under the large retaining clip, then
pulling it back so it fits under the two wheel
tabs.
7. After replacing the dichroic, you may need to clean it by using a soft, lint-free
cotton cloth and a mild glass cleaning solution (containing no ammonia).
8. Replace the bezel and engage the two bezel latches unless there are other
dichroics, lithos, or effects you want to replace.

Replacing Lithos

To replace a litho in the litho wheel:
1. Remove the fixture's bezel cover by releasing the two bezel latches (see Figure
7-8).
2. Manually rotate the litho wheel
until the litho you wish to replace is
easy to access (see Figure 7-9).
3. Locate the four plastic tabs built
into the wheel housing (see Figure
7-12).
4. Locate the tip of the metal spring
(which should be under one of the
four plastic tabs).
5. Carefully grasp the tip of the spring
with your finger and pull it out from
under the tab.
6. Rotate the spring as you remove it from the wheel.
