If the projector’s lens becomes damaged or broken it should be replaced. If the lamp
becomes damaged or deformed in any way it must be replaced. If the light from the lamp
appears dim this would normally indicate that it is reaching the end of its life and it should
be changed at once, old lamps run to the extremity of their life can explode. If the projector
does not function, check the power fuse inside the projector, it should only be replaced by
fuse with the same specified value. When changing the fuses, please undo the 4 M6
screws on the base of the projector and then open the base cover. Should these be
damaged call a qualified technician before replacement. The projector has a thermal
protection device that will switch off the projector in case of overheating.
Any maintenance work should only be carried out by qualified
technicians.
To ensure the reliability of the projector it should be kept clean. The lens and dichotic
colour filters should also be regularly cleaned to maintain an optimum light output.
Do
NOT use any type of solvent on dichotic colour filters.
Cleaning frequency depends on the environment in which the fixture operates: damp, smoke
or particularly dirty surroundings can cause greater accumulation of dirt on the unit’s optics.
A soft cloth and typical glass cleaning products should be used in cleaning. It is
recommended to clean the external optics at least once every 20 days and clean the
internal optics at least once every 30 / 60 days.
Do not use any organic solvent, e.g. alcohol, to clean the reflector,
colour filters or housing of the apparatus.
