The CP2000 high-intensity lamp and electronics rely on a variety of cooling components to reduce internal operating temperatures. Regular checking and maintenance of the entire cooling system is critical to prevent overheating and sudden projector failure, and helps to ensure reliable operation of all projector components over time.

Never attempt to conduct maintenance on an operational (live) projector. Turn the projector lamp off at least ten minutes before turning the projector off. It is crucial that you leave at least ten minutes between powering down the lamp and turning off the projector as this provides sufficient time for the internal lamp cooling fans to properly cool the lamp. Without such a precaution the lamp has the potential to explode, causing injury and or property damage.

The liquid cooler system circulates liquid to and from the DMDs (Digital Micro Mirror Devices used to deliver DLP™ Dinema Technology) in the CP2000 projection head; reducing their operating temperature to an acceptable level. Periodically check the coolant level visible through the coolant gauge/window on the non-operators side of the pedestal (Picture 1).

Make sure the coolant level remains between the two notches and preferably remains closer to the top notch. However should the liquid cooling system fail, it will trigger an over-temperature alarm.

Open the pedestal door (Picture 2) and locate cooler (Picture 3). The cooler sits in a cradle with ducting to circulate the cooling mix. It is unnecessary to remove the cooler from its cradle, the cap can be unscrewed and the cooler filled with a Christie’s 50/50 mix of distilled water and ethylene glycol – be careful not to overfill (Picture 4). Replace cap and close pedestal door.
