Tools:
• #2 Philips screwdriver
• Lint-free cotton gloves
WARNING: Remove power from luminaire before performing maintenance. Patterns can be HOT
after operation. Allow the fixture to cool before removing patterns.
To replace an effects pattern on Rotating Effects Wheel:
Step 1. Remove power from luminaire.
Step 2. Remove bottom head cover by loosening the four 1/4-turn screws.
Step 3. As shown in Figure 2-6 , open door on the cooling-air duct.
CAUTION: Do not touch patterns with bare fingers. Wear cotton gloves or other covering while
replacing or cleaning patterns. To clean patterns, use isopropyl alcohol and soft cloth.
Step 4. Rotate Yellow Wheel until cut-out faces up.
Step 5. Rotate Effects Pattern Wheel to desired pattern.
Step 6. At pattern’s planet gear, gently rotate two planet gear latches that secure pattern planet gear.
Step 7. Remove planet gear containing the pattern from assembly.
Step 8. If replacing pattern, perform the following, if not proceed to Step 9.
a. At planet gear, rotate retaining spring from assembly.

over neighboring planet gear assemblies.
Step 12. Close the air-duct door.
