Filter ReplacementWhenever you replace the lamp – or more often if the projector is installed in an extremely
dusty environment – you should also replace the two filters located at the front and right
side of the projector.
1. Loosen the six screws holding right side filter access
panel in place. Then, remove the panel.
2. Loosen the screw holding front filter access panel in
place. Then, remove the panel.
3. Pull the filters out of the projector and discard. Do not
reuse filters.
4. Insert the new filters with the wired side in.
5. Replace the filter access panels and tighten the
screws to secure them.
Always record the serial number of a new lamp. Do this only if you have
just installed a new lamp. This will ensure that the lamp timer is not reset
on an old lamp and that the number of hours logged on the lamp is
accurate.
