Section 4: Maintenance
d. Handling by the cathode end only, unscrew the lamp from the cathode connector. Carefully remove the
lamp from the projector and immediately place it inside the protective cover or original packaging.
Caution! 1) Handle the lamp by the cathode/anode end shafts only, never the glass.
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.
f. With the lamp removed, visually inspect the reflector for dust. Clean the reflector if necessary as
described earlier in
STEP 5: Remove the Protective Cover from the New Lamp
Remove tape, knurled nut and locking star washer securing the lamp within its cover.
STEP 6: Install New Lamp
a. If you are installing a different type of lamp from the original, ensure the correct position of the anode
yoke. Refer to
b. 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 com-
partment (labeled). NOTE: The purpose of the extension nut is to correctly position the lamp for opti-
mal light output.
c. Insert the threaded cathode (-) end of the lamp into the negative lamp connector nut located in the rear
of the lamp compartment. (Figure 4-2) Using both hands, hand-tighten this end into the threaded nut.
Caution! 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.
d. Rest the anode (+) end of the lamp on the anode yoke and slip the positive lamp connector over the
bulb end. (Figure 4-2) 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 clamp screw is tightened. For all other lamp
types, keep the "flat" part of the anode end of the lamp facing up. WARNING! Explosion hazard -
Do not apply torque to the anode end of the lamp.
e. Tighten screws in both negative and positive lamp connectors. Important! Proper electrical contact
prevents resistance in the lamp connectors. CAUTION! 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.
