Regular cleaning of the fixture is most important to keep a good perfomance over a long
period of time. Especially removing dust and grease from the inside as well as cleaning the
fans ensures reliable perfomance of the Varyscan.
Open the cover by loosening the screws. Use a brush and a vacuum cleaner to remove
dust from the inside. Make sure not to bend or damage the mechanical and electorical
parts inside of the fixture.
Incompetend performace of the maintenance will invalidate the warrany claims. Consult
qualified service personnel.
For a maximum light output the optical system has to be cleaned from time to time.
Loosen the screws holding the top cover and remove it.
Remove lamp before cleaning the optical parts of the fixture.
Use a soft cloth and gently whipe reflector, lenses and colour filters. You also may
use a pair of tweezers and a regular glass cleaner.
