MAINTENANCE
Make sure the area below the installation place is free from unwanted persons during servicing.
Switch off the unit, unplug the mains cable and wait until the unit has been cooled down.
During inspection the following points should be checked:
All screws used for installing the device and any of its parts should be tightly fastened and may not be
corroded.
Housings, fixations and installations spots (ceiling, truss, suspensions) should be totally free from any
deformation.
When an optical lens is visibly damaged due to cracks or deep scratches, it must be replaced.
The mains cables must be in impeccable condition and should be replaced immediately when even a
small problem is detected.
In order to protect the device from overheat the cooling fans (if any) and ventilation openings should be
cleaned monthly.
The interior of the device should be cleaned annually using a vacuum cleaner or air-jet.
The cleaning of internal and external optical lenses and/or mirrors must be carried out periodically to
optimize light output. Cleaning frequency depends on the environment in which the fixture operates: damp,
smoky or particularly dirty surroundings can cause greater accumulation of dirt on the unit’s optics.
Clean with a soft cloth using normal glass cleaning products.
Always dry the parts carefully.
Attention: We strongly recommend internal cleaning to be carried out by qualified personnel!
