16- PERIODIC CLEANING
16.1- Lenses and reflectors
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.
16.2- Fans and air passages
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.
17- PERIODIC CONTROLS
Attention
Disconnect mains power prior to opening the projector housing.
Mechanical parts
Periodically check all mechanical parts, gears, guides, belts, etc. for wear and tear,
replacing them if necessary.
Periodically check the lubrification of all components, particularly the parts subject to
high temperatures.
If necessary, lubrificate with suitable lubrificant, available from your DTS distributor.
Check the tension of the belts and adjust it if necessary.
Electrical components
Check all electrical components for correct earthing and proper connection of all
connectors, refastening if necessary.
Fuse replacement
Locate the fuse, which protects the lamp and electronics, in the base of JED.
Using a multimeter, test the condition of the fuse, replacing it with one of equivalent
type (T 2A 250V) if necessary.
