It is easy to insert or exchange the slides provided after removing the cover as shown below. With a
different slide you will gain a different light beam effect or advertising function.
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 fuse
on the power socket of the projector, they should only be replaced by fuse of the same specified
value 6.3A/250V (fast blow, 5mmx20mm). On the main PCB inside the projector there is also a fuse
rated 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 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 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.
