COOL LAMP COMPLETELY

The arc lamp operates at very high pressures that increase with temperature. Failure to

allow the lamp to sufficiently cool prior to handling increases the potential for an

explosion. After turning the lamp OFF, it is crucial to wait at least 10 minutes before

turning OFF the projector breakers, disconnecting AC and opening the lamp door. This

provides enough time for the internal lamp cooling fans to properly cool the lamp.

For all other precautions critical for safe removal and replacement of the lamp, refer to 4.4

Replacing

Lamp and Filter.

4.2 MAINTAINING PROPER COOLING

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, sudden projector failure and helps to ensure reliable operation of all

projector components over time.

4.2.1 VENTILATION

Vents and louvers in the projector covers provide ventilation, both for intake and exhaust.

Never block these openings. Do not install the projector near a radiator or heat register, or

within an enclosure.

4.2.2 AIR FILTER

It is recommended that you replace the air filter (located near the lens corner of the projection head)

whenever you replace the lamp or sooner, when operating in a dusty or dirty environment. A clogged

filter reduces air flow, and can lead to overheating and projector failure. Check monthly. For more

information, refer to 4.4

Replacing Lamp and Filter. It is also recommended that you visually check

the laminar airflow device (LAD) just beyond the filter opening. The LAD should be nearly white or

light gray in color.

4.2.3 LIQUID COOLER

The liquid cooler system circulates liquid to and from the DMDs in the CP2000 projection head,

reducing their operating temperature to an acceptable level. Periodically check the coolant level visible

through the gauge/window on the non-operator's side of the pedestal. Ensure it remains between the

two notches (preferably closer to the top notch). If the liquid cooling system should fail, it will trigger

an over-temperature alarm window.

WARNING

Never attempt to access the lamp while it is ON.

Wait at least 10 minutes after the lamp is turned OFF before powering down,

disconnecting from AC and opening lamp door.

Shock hazard - Disconnect from AC at both wall breakers before opening the lamp

house.
