ERA 600 Performance Safety and Installation Manual
• Avoid touching the other gobos when removing a gobo from a rack: the sharp edge of one gobo can
scratch the others.
• Keep gobos perfectly clean to reduce the risk of heat damage.
• When cleaning gobos, use a repeated dabbing action rather than a rubbing action. When rinsing, use
distilled or even better deionized water to avoid residue that will appear as drying marks.
• If possible, clean the coated side of gobos with dust and oil-free compressed air only. If the coated side is
contaminated with oil, clean with isopropyl alcohol and optics cleaning tissues.
• Clean the uncoated side of gobos with isopropyl alcohol or photographic quality lens-cleaner and optics
cleaning tissues.
• Do not try to clean gobos in an ultrasound bath, as this may cause delamination of the coating.
• Do not use acidic or alkaline cleaning solutions, as they will attack the aluminum coating.
• Correct gobo orientation is critical. Read the guidelines given later in this chapter carefully before
installing a gobo.
Opening the head for access
To open the head for access to the rotating gobos:
1. Disconnect the fixture from power and allow to cool for 30 minutes.
2. Place the fixture on a suitable work surface.
3. See Figure 10. Apply the tilt lock A.
4. Remove the four retaining screws B from one of the head covers and lift the cover away from the head
slightly. Press the retaining clip C on the cover’s safety wire in towards the head chassis, slide the clip
until you can remove it, and then remove the safety wire and head cover completely from the fixture.
5. Remove the other head cover in the same way.
When closing the head, follow the above procedure in reverse. Check that the head covers are held
securely after you have reinstalled them, and release the tilt lock before reapplying power or packing the
ERA 600 Performance in its flightcase.
