7. Remove the new lamp from the protective case. NOTE: Before removing the lamp from the case loosen
the cathode screw and remove the cathode nut from the lamp.
8. Install the new lamp:
NOT over-tighten. DO NOT stress the glass in any way. Check leads. Ensure the anode (+)
lead between the lamp and igniter is well away from any cinema projector metal, such as the
reflector or firewall.
a. Hold the anode end of the lamp in your left hand and angle it up through the hole in the back of the
reflector assembly. Insert your right index and middle finger through the back front of the reflector and
guide the lamp onto the cathode clamp. Be careful not to hit the lamp against the reflector.
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.
c. 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.
d. 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.
e. Tighten the anode and cathode set screws.
