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. The projector has overheat
protection device that will switch off the projector in case of overheating. Should it happen, check if the fans are blocked or not, or if
they are dirty, clean them before switching on the projector again.
Any maintenance work should only be carried out by qualified technicians.
LUBRICATION
To ensure the smooth rotation of the rotating gobos and movement of the lens for focusing, it is recommended that the bearings for
the rotating gobos and the 2 sliding tracks for the focusing lens holder be lubricated every two months. Use only high quality,
high-temperature grease .
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 containing chemical elements on dichroic colour filters.
Cleaning frequency depends on the environment in which the fixture operates. 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.
