while air bubbles are pressed out of the circuit.
Caution: Switch off the projector immediately in case the pump is sucking air (no circulation of liquid). Bypass the cooling
circuit of the light processor and inject cooling liquid into the main cooling circuit using a syringe. Ensure that you
don’t inject air bubbles.
Caution: Make sure that air bubbles coming out of the tube in the bottle doesn’t enter the other tube in the bottle.
6. Switch off the projector after all air bubbles are expelled. This will take approximately 10 minutes.
