Section 2: Basic Operation

2.1.3 Lamp Precautions

Any Xenon arc lamp used in the CP2000-SB is under high pressure and must be handled with great care at all
times. Lamps may explode if dropped or mishandled.

Wear Protective Clothing

Never open the lamp door unless you are wearing authorized protective clothing such as that included in a
Christie Protective Clothing Safety Kit (598900-095). Recommended protective clothing includes-but may not
be limited to-protective gloves, latex lab gloves, double-layer 0.040" acetate face shield, and a quilted ballistic
nylon jacket or a welder's jacket. NOTES: 1) Christie's protective clothing recommendations are subject to
change. 2) Any local or federal specifications take precedence over Christie recommendations.

Cool the Lamp Completely

least 10 min. after lamp shut-off before powering down, disconnecting from AC and
opening the lamp door. 2) SHOCK HAZARD. Disconnect from AC at BOTH wall
breakers before opening the lamphouse.
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! For all other precautions critical for safe removal and replacement of the lamp, refer to
Section 4.1 Maintenance and Cleaning.
2.2

Maintaining Proper Cooling

The CP2000-SB 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.

2.2.1 Ventilation

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.

2.2.2 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, in dusty or dirty environments. A clogged filter reduces air flow, and can lead
to overheating and failure of the projector. Check monthly. Refer to
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.
