Whilst every possible precaution has been taken to ensure the trouble-free operation of your
ProSpot LX
, the following
periodic maintenance is highly recommended. Prior to undertaking any maintenance procedure, make sure the fixture is
disconnected from mains power.
Opening the housing:
1) Using a Philips head screwdriver, remove the four screws located at both the front and rear of the projector head which
affix the top housing and those for the bottom housing, as shown in the diagram below:
Fuse replacement
Locate the 3 protection fuses:
Two are located on the master circuit board and protect the lamp circuit and the electronics. A third is located externally on
the side of the base of the projector and offers protection to the entire projector.
Use a multimeter to check the condition of the fuses, replacing them with fuses of similar value if required.
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 cotton cloth, dampened with a specialist cleaning solution.
Fans and air passages
The fans and air passages must be cleaned approximately every 6 weeks; the period for this 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 a sui-
table lubricant, available from your coemar distributor.
Electrical 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 housing!
