ASSEMBLY PROCEDURE
WARNING
DO NOT REMOVE THE PROTECTIVE COVER FROM THE LAMP UNTIL INSTRUCTED TO DO SO!
WARNING
DO EXERT ANY FORCE ON THE QUARTZ PORTIONS OF THE XENON BULB AT ANY TIME!
NOTE
IF THE FRONT LAMP HOLDER HAS NOT BEEN DISASSEMBLED, SEE THE LAST STEPS IN THE
APPROPRIATE DISASSEMBLY INSTRUCTIONS.
1. Untie the cord on the anode (+) end of the protective cover. Do not remove the cover at this time!
2. Fasten front lamp holder to the globe by placing the anode end (large electrode) of the lamp in the lamp
holder and aligning the stud on the end of the lamp ferrule with the channel in the nose of the lamp holder
body. Slide the lamp completely down the channel as far as it will go.
4. Replace the clamp and reinstall the (2) clamp retaining screws located on the side of the lamp swivel hub
using a 5/32" allen wrench.
5. Install the bulb into the fixture by inserting the cathode (-) end of the lamp through the opening in the reflector.
6. Insert the end of the lamp ferrule into the opening in the rear lamp holder receiver block and align the threads
by turning the bulb counterclockwise until the bulb threads drop into the receiver threads.
NOTE
DO NOT OVER TIGHTEN THE LAMP IN THE RECEIVER BLOCK AS THIS MAY CAUSE THE LAMP TO
"FREEZE" IN THE RECEIVER BLOCK MAKING IT DIFFICULT TO REMOVE. TIGHTEN THE LAMP JUST
ENOUGH TO APPLY SPRING PRESSURE TO THE THREADS BUT NOT SO MUCH AS TO BOTTOM OUT
THE LAMP FERRULE COMPLETELY AGAINST THE RECEIVER BLOCK.
7. Gently rotate the bulb clockwise until resistance is felt.
8. At this point, the bulb should be in contact with the spring plunger assemblies. Gently turn the bulb an
additional 1/16-1/8 of a turn to load the threads with the spring plungers.
9. Secure the front lamp holder to the spider with the shoulder bolt, spring, and washer that was removed during
disassembly.
10. Reconnect the focus rod swivel joint to the spider arm using the 5/16" and 3/8" open end wrenches. Do not
turn the swivel joint or focus rod.
11. Reconnect the (2) short leads from the spider to the front lamp holder using the (2) brass bolts and washers
that were removed during disassembly.
