Cleaning of the lens
Before carrying out any intervention on the fixture, cut off all external power sources and
place appropriate work-in-progress warnings on the systems.
Wait for the discharging time (at least 5 minutes) and check using appropriate instruments
that there are no residual energies before accessing the electrical equipment.
Clean the external surface of the lens with neutral and non-abrasive products using clean clothes.
The external cleaning operation of the lens take place directly on the runway and do not require the removal or the
opening of the fixture. In normal conditions of use it is not necessary to clean the lens internally.
Do not use solvent or diluent products to avoid damaging the glass lens.
In case the lens is damaged, replace it.
