Danger! Intense heat. Avoid contact by persons and materials. The exterior of the fixture can get
very hot - up to 120° C (248° F). Disconnect the fixture from AC power and allow it to cool
for at least 45 minutes before handling.
Do not removing covers while the fixture is powered on as this exposes dangerous live
electrical circuits, hot surfaces, and a lamp under high pressure.
1. Disconnect the fixture from AC power and allow it to cool.
2. Remove the top cover of the fixture head using a flathead screwdriver to loosen the four quarter-turn
screws. The top and bottom cover look the same, but the top cover is found by checking if the text on the
back of the head is oriented correctly (top) or not (bottom) as illustrated here.
3. Turn the gobo wheel to access the desired position.
4. Remove the gobo holder from the gobo wheel.
5. Squeeze the ends of the retention spring together and remove. Push the gobo out from the back and
remove.
6. Orient the gobo as shown in “Gobo orientation” on page 17 and insert the replacement gobo into the
holder. Secure the gobo with the retention spring.
