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 fuses on the
power socket of the projector, it should only be replaced by fuse of the same specified value 4A/250V
(fast blow, 5mmx20mm). Should these be damaged call a qualified technician before replacement.
The projector has thermal protection device that will switch off the projector in case of overheating,
should either of these operate, check that the fans are not blocked, and if they are dirty clean them
before switching on the projector again. Check that the fans are operational, if not call a qualified
technician.
Any maintenance work should only be carried out by qualified technicians.
To ensure the reliability of the projector it should be kept clean. It is recommended that the fans should
be cleaned every 15 days. The lens and dichroic colour filters should also be regularly cleaned to
maintain an optimum light output.
Do NOT use any type of solvent on dichroic 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 housing of the
projector.
