Installing The New Lamp - Christie CP2208 Service Manual

Installing the new lamp

Caution! 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. Check leads. Ensure the anode (+) lead between the
lamp and igniter is well away from any projector metal, such as the reflector or fire wall.
1. Remove the tape from the ends of the protective case.
2. Remove the plastic packing material from the lamp.
3. Remove the cathode nut from the lamp before removing it from the case.
4. For CDXL-14 or CDXL-16 lamps:
a. Install the lamp extension nut on the cathode clamp. To provide access to the locking
screw on the extension nut, rotate the extension nut until the locking screw faces upward
toward the projector lid.
b. Tighten the cathode screw with a hex key.
c. Thread on and hand-tighten the cathode nut. Ensure the smooth portion of the nut is
against the cathode clamp.
d. Hold the anode end of the new 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 of the reflector and thread the cathode end of the lamp into the extension nut.
When threading the lamp into the extension nut, make sure the anode wire does not hit
the reflector or the UV filter.
e. Tighten the extension nut screw.
f. Move to step 6.
5. For CDXL-19SC or CDXL-21S1 lamps:
a. Hold the anode end of the new 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 of the reflector and guide the lamp onto the cathode clamp. Be careful not to hit the
lamp against the reflector
b. Thread on and hand-tighten the cathode nut. Ensure the smooth portion of the nut is
against the cathode clamp.
c. Tighten the cathode screw with a hex key.
d. Hold the anode end of the new 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
