1 Disconnect the fixture from AC power and allow it to cool.
2 Remove the front cover.
3 Remove the three prism module screws. There
are two screws on the color wheel side and one
screw on the gobo wheel side.
4 Unfold the flexible wire retainers on each side of
the chassis, just behind the prism module.
5 Unplug the color wheel sensor cable.
6 Lift the prism module out of the chassis. When
the lower prism motor nears the color wheel
sensor, tilt the prism module forward to avoid
damaging the sensor connection pins.
7 Unplug the motors and remove the prism
rotation belt.
8 Working through the round hole, lift the retention
spring off the back of the prism holder.
9 Rock the prism gently from side to side while
pulling lightly to work the prism out of the
bearing. Do not use force. If the holder gets
stuck, press it back into the bearing and try
again.
10 Gently insert the replacement prism into the
rotation bearing. Install the prism rotation belt.
11 Place the module prism-down on a clean surface
with the prism centered in the round hole. Hold
the unbent end of the retention spring in the
prism holder groove with one hand and work the
spring into the groove with your other hand.
12 Plug in the prism motors: the longer of the two
cables is for the larger of the two motors.
13 Tilt the bottom motor away from the color wheel
sensor as you insert the module into the fixture.

connection pins, bring the module back to
vertical and press it down into position so that
the module tabs seat in the chassis slots.

each side. Reconnect the color wheel sensor

three screws.
