b. Insert the threaded cathode (-) end of the lamp into the negative lamp connector nut located in the rear
of the lamp compartment. (Figure 6-2) 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 cinema projector metal such as the reflector or firewall.
c. Rest the anode (+) end of the lamp on the anode yoke and slip the positive lamp connector over the
bulb end. (Figure 6-2) 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.
d. Tighten the anode and cathode set screws.
9. Re-install the front lamp duct. As you install the front lamp
duct, lift the small light shield on the rear lamp duct cover so
that it does not get jammed between the two pieces when they
come together. (Figure 6-3) To ensure a good fit between the
two pieces, squeeze the top and bottom cover snaps to ensure
they are locked in place. The light shield should move freely to
the touch.
10. Close the internal lamp door and manually turn the 2
thumbscrews to lock it in place.
11. Turn the circuit breaker for the cinema projector on.
12. On the Touch Panel Controller (TPC), tap and hold the green
