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 4-2. Make 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. Handling by the cathode end only, unscrew the lamp from the rear connector and carefully remove
from the projector. Immediately place the lamp inside the protective cover (saved from previous instal-
lation) and then seal it in a heavy carton on the floor where it cannot fall or be bumped. Warning!
Handle box with extreme caution—the lamp is hazardous even when packaged. Dispose of lamp box
according to safety regulations for your area.
d. With the lamp removed, visually inspect the reflector for dust. Clean if necessary as described in
tion 4.1 Maintenance and
STEP 7 - Remove New Lamp from Protective Cover
a. Remove tape, knurled nut and locking star washer (if present) securing the lamp within its cover.

your next lamp disposal or for warranty return of an expired lamp.
STEP 8 - Install New Lamp
a. With protective clothing and shield on, insert the threaded cathode (–) end of the lamp into the nega-
tive lamp connector nut located in the rear of the lamp compartment and screw in fully (Figure 4-1,

Do not over-tighten. Do not stress the glass.
b. Rest the anode (+) end of the lamp on the lamp cradle as shown in Figure 4-1, right, and slip the posi-
tive lamp connector over the bulb end.
