4.1 Cleaning the unit and maintenance
• Make sure the area below the installation place is free from unwanted persons during set-up.
• Switch off the unit, unplug the main cable and wait until the unit has cooled down.
• All screws used for installing the device and any of its parts should be tightly fastened and should not be corroded.
• Housings, fixations and installation spots (ceiling, trusses, suspensions) should be totally free from any deformation.
• When the lens is visibly damaged due to cracks or deep scratches, it must be replaced.
• The main cables must be in impeccable condition and should be replaced immediately even when a
small problem is detected.
• In order to protect the device from overheating 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.
• It is recommended to clean the plastic panel of the unit at regular intervals, from impurities caused by
dust, smoke, or other particles to ensure that the light is radiated at maximum brightness. For cleaning,
disconnect the main plug from the socket. Use a soft, clean cloth moistened with a mild detergent. Then
carefully wipe the plastic pane dry. For cleaning other housing parts use only a soft, clean cloth. Never
use a liquid, it might penetrate the unit and cause damage to it.
Warning: we strongly recommend internal cleaning to be carried out by qualified personnel!
