Section 3: Basic Operation
Note that only qualified service technicians are permitted to open any enclosure on the product, and only if
AC has been fully disconnected from the projection head and ballast.
Warning!
SHOCK HAZARD.
Disconnect projection head and ballast from AC before opening any enclosure.
3.1.3 Lamp Precautions
Xenon arc lamps are 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 P/N 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.
Warning!
EXPLOSION HAZARD —Wear authorized protective
clothing whenever the lamp door is open!
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
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!
Warning! 1)
Never
attempt to access the lamp while the lamp is on.
2)
Wait at least 10 min. after lamp shut-off before powering
down, disconnecting from AC and opening the lamp door. 3) 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 Section 4.1 Maintenance and Cleaning .
3.2 Maintaining Proper Cooling
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.
3.2.1 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.
3.2.2 Air Filter
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. Refer to Section 4.1 Maintenance and Cleaning 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.
