Martin Stagebar 2 RGBAW User Manual page 17

Do not use abrasive, caustic or solvent-based products for cleaning, as they can damage plastic or painted
surfaces.
To clean the fixture:
1. Disconnect the fixture from power and allow it to cool for at least 10 minutes.
2. Vacuum or gently blow away dust and loose particles from the fan blades and grilles in the fixture's end
caps with compressed air.
3. Clean the front cover with a soft cloth dampened in a warm water/detergent solution.
4. If the lens arrays require cleaning, remove them as described on page 17 and wash them in a hot
water/detergent solution with a soft brush. Dry completely before reinstalling.
5. See Figure 3. If a cooling fan or grille requires more thorough cleaning, loosen the fan assembly
retaining screw (arrowed) slightly and slide the assembly out of the end cap for access. Do not strain the
wires to the fan. Brush dirt from the fan blades with a soft brush, preferably in conjunction with a vacuum
cleaner.
6. Avoid trapping wires while reinstalling the fan assembly.
Removing and installing LED lens arrays
The LED lenses installed at the factory are constructed in arrays of 9 lenses. The lenses concentrate the
LED output into a narrower beam angle. Lens arrays can be removed to give a broad beam and must be
removed to obtain smooth color using the diffuser front.
To remove or install a lens array:
1. Isolate the fixture from power. If the fixture has been in use, allow it to cool for at least 10 minutes.
2. See Figure 4. Loosen the two captive screws (arrowed) on the end cap and swing the end cap open.
3. Slide the front cover out of the fixture.
