Cool the Lamp Completely
The arc lamp operates at a very high pressure that increases with
temperature. Failure to allow the lamp to sufficiently cool prior to
handling increases the potential for an explosion causing personal
injury and/or property damage. After turning the lamp off, it is
crucial that you wait at least 10 minutes before turning off the rest of
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. Cool completely before handling. Again, always wear protective clothing!
• Never attempt to access the lamp while the lamp is on
• Wait at least 10 min. after lamp shut-off before powering
down, disconnecting from AC and opening the lamp door.
SHOCK HAZARD. Disconnect from AC at
BOTH wall breakers before opening the lamphouse.
For all other precautions critical for safe removal and replacement of the lamp, refer
to 6.4. Replacing the Lamp & Filter.
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.
Vents and louvers in the projector covers provide ventilation, both for
intake and exhaust. Never block or cover these openings. Do not
install the projector near a radiator or heat register, or within an
enclosure.
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, in dusty or dirty
environments. A clogged filter reduces air flow, and can lead to overheating and
failure of the projector. Check monthly. See 6.4, Replacing the Lamp & Filter for
instructions. 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.
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, and make sure that it remains between the two notches
(preferably closer to the top notch).
