8. Cleaning and Maintenance
All screws should be tightened and free of corrosion.
The housing, the lenses, the mounting supports and the installation location (e.g. ceiling, suspension,
trussing) should not be deformed, modified or tampered with; e.g. do not drill extra holes in mounting
supports, do not change the location of the connections…
Mechanically moving parts must not show any signs of wear and tear.
The electric power supply cables must not show any damage. Have a qualified technician maintain the
device.
Disconnect the device from the mains prior to maintenance activities. Let the device cool down.
Use a vacuum (or dry compressed air) and a soft brush to remove dust collected on the external
surface/vents.
Clean all external optics and glass/transparent surfaces with a mild soap solution, ammonia-free glass
cleaner, or isopropyl alcohol. Apply the solution directly to a soft, lint-free cloth or a lens cleaning tissue.
Softly drag any dirt or grime to the outside of the external optics or glass/transparent surface. Gently polish
until free of haze and lint. Dry carefully after cleaning.
Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
