12- OPENING UP THE PROJECTOR HOUSING
13.1 Lenses and raylight reflector
13.2 Fans and air passages
13.3 Lamp
13.4 Mechanical parts
It is possible to inspect the inside of the projector by removing the cover as indicated below.
1) Loosen the screws which fix the upper and lower covers (photo 1) and unscrew the side covers
(photo 2).
2) Once unscrewed, simply lift the covers to access the internal components (photo 3).
Even a fine layer of dust can reduce the luminous output substantially. Regularly clean all lenses and
the reflector using a soft cotton cloth, dampened with a specialist lens cleaning solution.
The fans and air passages must be cleaned approximately every 6 weeks. This periodic cleaning will
depend of course, on the conditions in which the projector is operating. Suitable instruments for
performing this type of maintenance are a brush and a common vacuum cleaner or an air
compressor. If necessary, clean the fans and air passages more frequently.
The lamp should be replaced if there is any visible damage or deformation due to heat. This will help
to avoid the danger of the lamp exploding.
Periodically check all mechanical parts gears, guides, belts, etc. For wear and tear, replacing them if
necessary. Periodically check the lubrication of all components, particularly the parts subject to high
temperatures. If necessary, lubricate with suitable lubricant, available from your D.T.S. distributor.
Check the tension of the belts and adjust if necessary.
WARNING!
REMOVE MAINS POWER PRIOR TO ACCESSING THE PROJECTORS INTERNAL COMPONENTS.
