10. 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.
y
Clean with soft cloth using normal glass cleaning fluid.
y Always dry the parts carefully.
y Clean the external optics at least every 20 days. Clean the internal optics at least
every 30/60 days.
