Section 4: Maintenance
Do not allow anything to rest on the power cords. Locate the projector where cords cannot be abused by
persons walking on it or objects rolling over it. Never operate the projector if a power cable appears damaged
in any way.
Do not overload power outlets and extension cords as this can result in fire or shock hazards.
NOTE:
Only a Christie accredited service technician is permitted to open any enclosure on the product, and only
if the AC has been fully disconnected from the projection head and ballast.
4.1.3 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 #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. The face shield is provided with the projector.
Explosion Hazard
. Wear authorized protective clothing whenever the lamp door is open!
Never attempt to remove the lamp directly after use. The lamp is under increased pressure
when hot and may explode, causing personal injury and/or property damage.
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 (powering down), it is crucial that you wait at least 10 minutes
before turning the breaker/power switches OFF, 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 Christie-approved protective clothing!
Never attempt to access the lamp while it 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 AC before opening the
lamp door.
For all other precautions critical for safe removal and replacement of the lamp, refer to Section 4.4.1 Lamp
Replacement Procedure .
4.2 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.
