Maintenance
a. Remove the front lamp duct to reveal the cathode end (-) of the lamp.
b. Loosen the set screw securing the anode connector.
c. Loosen the set screw securing the cathode connector.
d. Slip the positive anode connector off the front of the lamp.
e. Hold the lamp from the cathode end and carefully unscrew the lamp from the cathode connector
ensuring not to make contact with the reflector.
f. With your free hand guide the cathode end out of the reflector, on an angle.
g. Before placing the old lamp into the protective case ensure the cathode nut is reinstalled. Place the
lamp, within the case, 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 local area safety regulations.
h. With the lamp removed, visually inspect the reflector for dust. If necessary, clean the reflector.
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. 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.
