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!
