Cool the Lamp Completely

The arc lamp operates at a very high pressure that increases with temperature.

DANGER

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!

WARNINGS

• 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.

DANGER

SHOCK HAZARD. Disconnect projection head and ballast

from AC before opening the lamp door.

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

refer to 4.4. 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 4.4, 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.
