6.4.1 Lamp Replacement Procedure

NOTE: For this procedure you will need a compatible Christie Xenon CDXL or CXL lamp as shown in
8 Specifications-never install a lamp intended for a different model or projector. Warning! 1) Make sure to
use the correct wattage lamp supplied by Christie. 2) Lamp replacement is to be done by a qualified service
technician only. 3) EXPLOSION HAZARD - Wear authorized protective clothing whenever the lamp door is
open! Never apply a twisting or bending force to the quartz lamp body.
Before You Begin
Read and follow all other general lamp precautions in
STEP 1: Turn Off Main AC
a. Allow the fans to run at least 10 minutes for cooling.
b. At the breaker panel on the projector, set the 3-phase MAIN AC circuit breaker to OFF.
Warning! Never attempt to remove the lamp when it is hot. The lamp is under great pressure when hot
and may explode, causing personal injury and/or property damage. Allow to cool completely.
STEP 2: Turn Off Remaining Circuit Breakers
After allowing the fans to run for at least 10 minutes, turn OFF the remaining INTERNAL and PROJEC-
TOR circuit breakers located on the breaker panel of the projector.
STEP 3: Disconnect Projector from AC Supply
STEP 4: Open the Lamp Door
With protective clothing and shield on, unlock the lamp door and open it. Refer to Figure 2-5 Open Pro-
jector for Access, on page 2-5. If desired, release the latch mechanism to remove the door entirely.
STEP 5: Open Cooling Compartment
Turn knob to open the inner lamp cooling compartment and reveal the cathode end (-) of the lamp.
STEP 6: Remove the Old Lamp and Inspect Reflector
a. Loosen set screws from negative/cathode (rear, 7/64") and positive/anode (front, 3/16") lamp connec-
tors. These screws are shown in Figure 6-2. NOTE: Be sure to apply minimal torque and DO NOT
STRESS the quartz tube.
b. Carefully slip the positive anode connector off the front of the lamp.
c. Handle the cathode end only. Unscrew the lamp from the rear connector and carefully remove it from
the projector. Immediately place the lamp inside the protective cover (saved from previous installa-
tion) and then seal it in a heavy carton on the floor where it cannot fall or be bumped. Warning! Han-
dle box with extreme caution. The lamp is hazardous even when packaged. Dispose of lamp box
according to safety regulations for your area.
