Ventilation and cooling
Vents and louvers provide ventilation, both for intake and exhaust. Do not install the projector near 
a radiator, heat register, or within an enclosur e. To ensure adequate airflow, keep a minimum 
clearance of 50 cm (20 inches) around the pr ojector and never block or cover the vents.
Inspect and clean the airflow interlocks
The projector uses two airflow interlocks. Check  and clean these switches to remove accumulated 
dust or dirt that could impede movement.
• Lamp blower vane switch, located wi thin the lamp cooling compartment. 
• Extractor vane switch, located inside the top duct on the projector lid. 
Inspect and clean the exhaust duct
Inspect the exhaust duct regularly and confirm that: • There are no obstructions or kinks within the ducting.
• All air intake areas are unobstructed.
• If using 2.0 or 3.0kW lamp, exhaust airflow must be at least 450 CFM (measured at the rigid end of the duct when not connected to the projector). 
• If using 4.5 or 6.0kW lamp, exhaust airflow bust be at least 600 CFM (measured at the rigid  end of the duct when not connected to the projector).
Inspect and clean the lamp blower
A clogged blower impeller or motor can reduce air  flow and lead to overheating and lamp failure.
1. Shut down the projector. 
2. Remove the three screws securing the rear side cover.
Warning!  Failure to comply with the following co uld result in death or serious injury.

Troubleshooting
This section provides information and procedur es for resolving common projector issues. If a 
projector issue cannot be resolved, contact a Christie accredited service technician.
Projector does not power on
• Make sure that all three circuit breakers on  the lamp power supply (LPS) are turned on.
• Make sure the projector circuit breaker is set to the on position.
• Check the status LEDs on the rear corners of th e projector for a fault condition. A flashing red 
LED indicates an alarm or warning preset with  the projector and a problem that must be 
addressed.
• Use the touch panel controller (TPC) status menu to troubleshoot further.
Lamp does not ignite
• Make sure all three breakers on the lamp power supply (LPS) are set to their on positions.
• Check and correct all interlock failures.
• Check the lamp power supply communication connections and restart the projector.
• Verify that the lamp has been installed and conne cted properly. Verify the condition of the lamp 
and that is not blackened or otherwise damaged.
• Verify the number of hours the lamp has operated . A lamp nearing the end of its operational life 
should be replaced.
Lamp suddenly turns off
• Increase the lamp power.
• Review and correct all interlock failures.
• Ensure the TPC has no temperature or fan RPM warnings. If all fans are running normally and  the air filters are not blocked, the ambient ai r temperature may exceed the maximum operating 
specification. If possible, reduce the ambient temperature.
