inlets and outlets as well as the optical LED lenses from time to time. For safe
operation it is absolutely essential that the fixture is kept clean and that dust, dirt and
smoke-fluid residues must not build up on, or within, the fixture. If they do, the
fixture's light output will be significantly reduced, and damages to the fixture may
occur. Regular cleaning will not only ensure the maximum light output, but will also
allow the fixture to operate reliably throughout its entire life.
A soft lint-free cloth moistened with any good glass cleaning fluid is recom-
mended. Under no circumstances should alcohol or solvents be used to clean
the fixture or its lenses!
5.1 Safety regulations
• Disconnect the fixture from the mains power before commencing any
maintenance work!
• Wait minimum 15 minutes after removing the power to allow the fixture to
cool down.
5.2 Maintenance Intervals (rule-of-thumb)
The maintenance schedule of any given fixture depends on the installation
environment. Hence no specific guidelines can be given. The cleaning intervals
given below are suggestions, based on practical experience. We suggest that
you start with these and develop your own maintenance schedule as you see
the fixtures performance in your specific environment.

Attention:
• Never let optical parts come into contact with oil or fat.
• Before running the fixture wait until all parts are touch dry.
• Never touch lenses with bare fingers.
