REPLACING THE FUSE
If the fuse is defective, replace the fuse with a fuse of the same type and value. Before replacing the fuse, unplug mains lead.
Procedure:
FIXTURE CLEANING
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 surrounding
can cause greater accumulation of dirt on the unit's optics.

Make sure the area below the installation place is free from unwanted persons during servicing

Housings, fixations and installations spots (ceiling, truss, suspensions) should be totally free from any deformation

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 fixture from overheat the cooling fans (if any) and ventilation openings should be cleaned
monthly.

The interior of the fixture should be cleaned annually using a vacuum cleaner or air-jet.

Clean with soft cloth using normal glass cleaning fluid.

Always dry the parts carefully.

Clean the external optics at least every month. Clean the internal optics at least every 30/60 days.
ATTENTION: We strongly recommend internal cleaning to be carried out by qualified worker!
