Whilst every possible precaution has been taken to ensure the trouble-free operation of your
ProSpot 150 LX
, the following perio-
dic
maintenance is highly recommended. We recommend that the voltage to the unit be removed prior to any maintenance procedu-
re taking place.
Opening the projector
1) Using a Philips head screwdriver, remove the three screws which affix the rear cover of the projector, as shown in the diagram.
2) Remove the cover.
Replacing the fuse
Locate the three protection fuses:
Two are located on the master PCB and protect the lamp circuit and the electronics and the third is located accessible on the base
of the unit protecting the entire unit.
Use a multimeter to check the fuses, replacing any faulty or damaged fuses with ones of equal value, dimensions and characteri-
stics.
periodic cleaning
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 cot-
ton cloth, dampened with a specialist lens cleaning solution.
fans and air passages
The fans and air passages must be cleaned approximately every 6 weeks; the period for this periodic cleaning will depend, of cour-
se, upon 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.
Periodic maintenance
lamp
The lamp should be replaced if there is any observable damage or deformation due to heat. This will avoid the danger of the lamp
exploding.
mechanicals
Periodically check all mechanical devices for wear and tear; gears, guides, belts, etc., 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
coemar distributor.
electronic components
Check all electrical components for correct earthing and proper attachment of all connectors, refastening if necessary.
Attention
Disconnect mains power prior to opening the inspection lid
