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 fuse in the projector base, it should only be replaced by fuse of the same
specified value 20A/380V (fast blow, ceramic). On the main PCB inside the projector there is also
a fuse rated 2A/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 this 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 a qualified technician.
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 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.
Do not use any organic solvent, e.g. alcohol, to clean the housing of the
projector.
