Open cooling compartment
Turn knob to open the inner lamp-cooling compartment and reveal the cathode end (–)
of the lamp. Refer back to Figure2.20.
Remove the old lamp and inspect reflector
Loosen set screws from negative/cathode (rear, 7/64”) and positive/anode (front,
3/16”) lamp connectors. These screws are shown in Figure6.2.
Make sure to apply
minimal torque and DO NOT STRESS the quartz tube.
Carefully slip the positive anode connector off the front of the lamp.
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 installation) 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.
With the lamp removed, visually inspect the reflector for dust. Clean if necessary as
described in
6.3, Maintenance and Cleaning.
Remove new lamp from protective cover
7.1 Remove tape, knurled nut and locking star washer (if present) securing the lamp
within its cover.
7.2 Handling at the ends only, extract the lamp from the cover. Set aside the
protective cover for re-use in your next lamp disposal or for warranty return of an
expired lamp.
Install new lamp
8.1 With protective clothing and shield on, insert the threaded cathode (–) end of the
lamp into the negative lamp connector nut located in the rear of the lamp
compartment and screw in fully (Figure 6.1, left). Hand-tighten only.
IMPORTANT:
Handle by the cathode/anode end shafts only, never the glass. Do not
over-tighten. Do not stress the glass.
