General
Maintenance
To maintain optimum performance and minimize wear, the user should clean the light
fixtures frequently. Usage and environment are contributing factors in determining the
cleaning frequency. As a rule, the user should clean the fixtures at least twice a month.
Dust build up reduces light output performance and can cause overheating. This can
lead to reduced light source life and increased mechanical wear.
CHAUVET® recommends cleaning the fixture’s external optics with a soft cloth using
normal glass cleaning fluid.
To clean a fixture, follow the recommendations below:
• Unplug the fixture from power.
• Wait until the fixture is cold.
• Use a vacuum (or dry compressed air) and a soft brush to remove dust collected
on the external vents and reachable internal components.
• Clean all external optics and glass surfaces with a mild solution of glass cleaner or
isopropyl alcohol, and a soft, lint free cotton cloth or a lens cleaning tissue.
• Apply the solution directly to the cloth or tissue and drag any dirt or grime to the
outside of the lens.
• Gently polish the external glass surfaces until they are free of haze and lint.
• When cleaning units with a movable mirror, you should keep the contact with the
mirror surface to a minimum to avoid scratching or damaging it.
Always dry the external optics and glass surfaces carefully after cleaning them.
If the fixture has one or more fans, refrain from spinning them using compressed
air.
Dust Screen
Cleaning
The Legend 1200E Wash fixture uses multiple fans. To prevent dust buildup on the
components of the optic path, each of the fans on the forward section of the moving
head have a dust screen as shown in the diagram below.
To access the dust screens, remove the bottom and top housings of the moving head,
at which point you will have be able to remove the housing sides. Once you have
cleaned the dust screens, reverse the process to replace them.
Despite having dust screens, the fixture still needs regular cleaning of its lenses,
color wheels, and the other components in the optical path.
