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 top cover of the head and remove the base plate of the base 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 of the head and remove the top cover.
Remove lamp before cleaning the optical parts of the fixture.

use a pair of tweezers and a regular glass cleaner.
