To replace a module simply reverse the steps above. Make sure that the module is straight and locates properly: there are two
pins on the top of the module that fit in holes in the inner casing.
PAL 1200 FX note: The PAL 1200 FX uses the same wiring harness as the PAL 1200 so that either unit may be converted to
the other. Connect the wires to the effect module as follows.

Be very careful when cleaning the optical components (color filters, glass gobos, lenses, reflector and mirror). The colored sur-
face on the filters is achieved by means of special multi-layer coatings and even small scratches in these might be visible. Use
only a clean, soft and lint-free cloth like the ones used for cleaning camera lenses. You may need to wet the cloth with a non-
aggressive glass cleaning liquid if the filters or lenses are greasy. It may also be necessary to clean the gobos and shutter blades
and special care should be taken not to damage these fragile parts.

Remove the CMY module and carefully clean:
• All six color filters.
• The diffusion filter (if mounted).

Remove the color/gobo module and carefully clean:
• The color filters. The color filters can easily be removed from the color wheel to ease cleaning.
• The gobos. If you have used the gobo indexing facility in your lighting programs then do not remove the gobos from the wheel
whilst cleaning these. Otherwise, you will need to reprogram all scenes with indexed gobos, if you are not able to replace the
gobo in exactly the same position.
• The condenser lens (if mounted).

The PAL uses a front coated mirror to ensure a sharp and un-distorted image. Clean the reflective side of the mirror using a
soft, lint-free cloth wetted with a non-aggressive glass cleaner.

To ensure proper cooling of the fixture it's important that the fans are free of dust. Clean the fans if the air flow seams to be
reduced. The fan grill at the rear end of the fixture can be removed by unscrewing the 3 Phillips screws that secure it to the
back plate.
