C.1 Pressure check of cooling liquid circuit
When should it be done ?
The pressure of the cooling circuit should be checked on regular times. At least when replacing the lamp.
How to check
1. Unplug the projector from the wall outlet.
2. On the input side of the projector, remove the side by turning the 3 quarter turn fastener studs a quarter turn counter clockwise.
3. Pull the top side of the cover out of its spring locks.
4. Check the manometer. The manometer is situate on the top right of the lamp house compartment. (image C-2)
The pressure should be ± 1 bar (with projector in OFF state). When lower than 0.5 bar, a corrective action should be taken by
qualified service personnel.
Any significant drops in pressure indicates leakage of liquid in the cooling circuit.
5. Hook on the side cover and close the 3 quarter turn fastener studs a quarter turn clockwise.
