While I can't answer too much on these specific models (I work with the ELM R18 director) I can offer some advice.
You will not find manuals for replacing the inner lamp as the manufacturer was only intending to have qualified shops replace the lamp (due to the risk of explosion). That is why you will find Warranty Void If Removed stickers on the lamp housing. I have been working with my lamp distributor who provided me with the materials I need to do it, but they (I'm sure for liability reasons) will not provide me with instruction on how to do it. It's at my own risk. Fortunately we have all the
safety gear necessary for my
safety, make sure you do as well. With some of the newer models of Christie (and promised by
Barco), lamp refurbish kits are being sold but there are no plans on doing this for older models.
The best way to prolong the life of a
projector is dillegence in cleaning. Make sure your filters are clean, especially if used in a high particulate environment (I will even use a prefilter in those areas especially if
fog is in use). Make sure that you have "clean"
power at all times. This can be particularly difficult if used in a rental situation and you are not in charge of verification. Check
Barco where you can find the specs on your
projector. Unfortunately, you will have to contact them directly to get the user
manual (should be available in .pdf) where you will find the recommended maintenance of the
projector.
