11.5 Check cooling liquid level
What should be done ?
The projector is liquid cooled. It is important that the liquid level is checked at regular intervals. We advise to check every 3 months.
The liquid level must be between Min. and Max. Significant drop in liquid level indicates a major leakage and requires immediate
attention.
How to check
1. Remove the left side cover (Light Processor side). see "Removal of the side cover", page 139.
2. Check the liquid cooling level in the reservoir.

Cooling liquid check
If the current liquid cooling level is somewhere between Min and Max, then no action should be taken.
If the current liquid cooling level is approaching the Min level point, than check for leakage in the cooling system prior starting
the refill procedure.
If you cannot see the level, open the filler cap and shine a torch into the reservoir
