e. Place the lamp 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.
3. Install new lamp.
a. Remove the protective cover from the new lamp by removing the tape, knurled nut and locking star
washer securing it to its cover.
b. If you are installing a different type of lamp from the original, ensure
the correct position of the anode yoke (Figure 5-43).
For 3.0kW CDXL-30SD lamps only: Install the lamp spacer provided with
the projector on the cathode end connector before installing the lamp.
Required for proper positioning of this lamp type. Also, ensure the anode
clamp is in the right position.
c. If installing a 3.0 kW CDXL-30SD lamp, make sure the lamp
extension nut supplied with the projector is installed on the cathode
end connector. If you are installing any other lamp type make sure
this extension nut is removed and threaded onto the unused stud
located on the baseplate in the lamp compartment (labeled).
NOTE: The purpose of the extension nut is to correctly position the
lamp for optimal light output.
d. Insert the threaded cathode (-) end of the lamp into the negative lamp
connector nut located in the rear of the lamp compartment. (Figure
5-44) Using both hands, hand-tighten this end into the threaded nut.
CAUTIONS! 1) Handle the lamp by the cathode/anode
end shafts only, never the glass. DO NOT over-tighten. DO NOT stress the glass in any
way. 2) Check leads. Make sure the anode (+) lead between the lamp and igniter is well
away from any projector metal such as the reflector or firewall.
e.
WARNING! Explosion hazard! DO NOT apply torque to the anode end of the
lamp. Rest the anode (+) end of the lamp on the anode yoke and slip the positive lamp connector over
the bulb end. (Figure 5-44) Using the 5mm Allen key, squeeze together with the anode clamp making
sure not to place any torque on the lamp quartz tube. IMPORTANT! For CDXL-30SD lamps,
make sure the "flat" part of the anode end of the lamp (if applicable) is facing in the 10
or 2 o'clock position once the lamp finger is installed in the 14mm threads and the
