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 projection head and ballast from
For all other precautions critical for safe removal and replacement of the lamp, refer
to 6.4. Replacing the Lamp & Filter.
The 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 on the lamp side 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) located nearby. The LAD should be nearly white or light grey in color.
The liquid cooler system circulates liquid to and from the DMDs in the CP2000-X
projection head, keeping their operating temperature at an acceptable level.
Periodically check the coolant level visible by removing the igniter grille (rear side
grille adjacent to the side input panel)—check for 1) leaks and 2) proper liquid level.
NOTE: A failure of the liquid cooling system will trigger an over-temperature alarm
condition, clearly indicated with status displays/lights at the rear of the projector.
The cooler should require filling only upon projector
