COOL LAMP COMPLETELY

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.
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
Lamp and Filter.

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
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.
