MAINTENANCE
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, aged lamps run to the extremity of their life might explode. If the projector
does not function, check the fuses on the power socket of the projector, they should only be replaced by fuses of the
same specification. 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.
KEEPING THE PROJECTOR CLEAN
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 reflector mirror, dichroic colour filters or housing of
the apparatus.
