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:

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 cinema projector metal, such as the

reflector or firewall.

a. Remove the cathode clamp from the lamp before removing it from the case.

b. 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.

c. Thread on and hand-tighten the cathode nut. Ensure the smooth portion of the nut is against the

cathode clamp.

d. Tighten the cathode screw (Figure 7-2/E) onto the cathode end of the lamp.

e. Align the ring terminal on the anode wire (Figure 7-2/B) with the mounting position (Figure 7-2/D),

ensuring the crimped side of the wire is facing out. Tighten the anode screw. NOTE: Route anode lead

away from nearby metal surfaces.

9. Close the internal lamp door and manually turn the 2 thumbscrews to lock it in place.

10. Close the rear access door. NOTE: Return the hex key to its holder before closing the rear access door.
