11.1 Cleaning and Maintenance
Regular inspections are recommended to insure proper function and extended life. Please refer all
other service issues to an authorized GTD service technician.
Attention! The damage results from dust, smoke, oil or abnormal use is not under the warranty.
Warning: Disconnect from the power source before open the shell. The coating is easy to be
scratched, so please be careful when cleaning the optical components. Do not use any
organic solvent, e.g. alcohol, to clean the reflector mirror, dichroic colour filters or
housing of the fixture.
When the lens is cracked or otherwise damaged, replace it timely.
If the LED lamp becomes damaged or deformed in any way it must be replaced.
If the light from the LED lamp appears dim this normally indicate that it is reaching the
end of its life span and should be changed at once. Aged LED lamps run to the extremity
of their life might explode.
If fixture does not function, check the fuse on the power socket of the fixture. Replace the
fuse of the same specification if it is blown.
The fixture is equipped with thermal-protection device that will switch off the LED lamp in
case of overheating. If this happens, please check that the fans are not blocked, and clean
them if they are dirty. Check whether the fans are operational. If not, call a qualified
technician. Find troubles and shoot them before switching on the fixture again. Any
maintenance work should only be carried out by qualified technicians.
