To be able to take out the slide-in modules of your Varyscan

, you have to screw off two screws 

of silver at the side-piece, up to the mark of the slide-in modules. Now you are able to take out 
the slide-in modules (sketch page 4).

Do not forget to lock in the slide-in modules after having completed  

your maintenance performances, by screwing in the screws of silver    

carefully! 

1. Cleaning of all optical parts 

 
You should clean the optical parts of your Varyscan

®

 periodically to restore maximum brightness 

of the scan. After having opened the casing as explained above, take out the effect wheel slide-in 
(see sketch page 4) and put it on an underlay in front of you. Take a fuzz-free rag and a detergent 
for windows and clean the effect filters on the effect wheel. 
Subsequently clean both lenses (sketch page 4). In order to clean the lens easily, loosen the 
screw which fixes the lens and remove  the lens. Now it is easy to clean from the outside and the 
inside. Take out the colour wheel slide-in in order to clean the dichroitic filters. Put in the lens, 
the effect wheel slide-in and the colour wheel slide-in. Do not forget to tighten the screw which 
fixes the lens. 
 

2. Cleaning of ventilation 

 
You should check regularly the function of the ventilators. Above all take care that ventilation 
inlets and the interior of the Varyscan* are free from fuzzes and other dust. Open both lids of your 
Varyscan

®

, by screwing off the screws from the lids. Now clean your Varyscan* carefully with a 

vacuum cleaner. Now screw down the lid. Take care that you use the sheet metal screws for 
closing the smaller lid.
