11.5 Check cooling liquid level
What should be done ?
The projector is liquid cooled. W hen running with a low liquid cooling level then the c ooling capacity is strongly reduced which results
in higher temperatures inside the projector. These higher temp eratures can cause an interruption of your film projection as the lamps
can be switched o ff by the software as a precaution.
To avoid this p roblem, we s trongly advise to check at least every 3 months the cooling liquid level in the cooling reservoir of the
projector.
How to check
1. R emove the side cover, see "Removal of the s ide c over", page 95.
2. C heck the liquid cooling level in the reservoir.

If the current liquid cooling level is appr oaching the Min level point, start the refill procedure.
If you ca nnot see the level, open the filler cap and shine a torch into t he reservoir
