17. Maintenance
Whilst every possible precaution has been taken to ensure the trouble-free operation
of your CF ZOOM AL, the following periodic maintenance is highly recommended.
Opening the projector:
The front inspection lid allows complete access to the projector’s internals.
For more detailed access to the unit remove the 4 screws (C), disconnect all 8 motor,
sensor and thermal contacts.
After this simple procedure, the whole motor assembly may be totally removed.
fuse replacement
Fuse replacement
Locate the fuse, which protects the lamp and electronics, in the base of the CF
ZOOM AL.
Using a multimeter, test the condition of the fuse, replacing it with one of equivalent
type if necessary.
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 speciali-
st 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 course, 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.
Attention
Disconnect mains power prior to opening the inspection lid
