To ensure a long and satisfying performance of the fixture, check function of the fans

is no dust or fluff covering the air inlets. To clean the fixture open lid of the head and
the baseplate. Use a brush and a vacuum cleaner to remove dust and fluff. Don´t
damage or bend any parts. Incompetend performace of the maintenance will invalidate
the warranty claims. Consult qualified service personnel.
