Cleaning and maintenance
It is required that the fixture should be kept clean and well maintained to ensure its reliability. Its lifespan mainly depends
on the working environment and proper operation. Should you have any questions, please consult a technical engineer of
GTD Lighting.
Notes
Damage resulted from dust, smoke, oil or improper use is not covered by warranty.
Warning
Disconnect the fixture from AC power, and let it cool down for at least 15 minutes before opening the housing. Make sure
to use a soft cloth to clean the optical components, and be careful, as the coating is easily scratched. Do not use any organic
solvent such as alcohol to clean the reflector mirror, dichroic color filters or housing of the fixture.
If the lens is cracked or otherwise damaged, replace it immediately.
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 indicates 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. Troubleshoot and correct the problem before switching on the fixture
again. Any maintenance work should only be carried out by qualified technicians.
