8. Fixture Cleaning
It is absolutely essential that the fixture is kept clean to ensure the maximum light-output and allow
the fixture to function reliably throughout its life. The fixture must be cleaned regularly to avoid dust,
dirt and smoke-fluid residues building up on or within the fixture. The cleaning frequency depends on
the application environment. Clean the fixture immediately if the dust enters it to avoid damage to
the optical lens due to excessive dust.
A soft lint-free cloth moistened with any good glass cleaning fluid is recommended, under no
circumstances should solvents be used.
Always dry the parts carefully.
Clean the external optical lens at least every 20 days.
