1. Check lamp cradle (anode end) location for your lamp
• For 4.5 or 6.0 kW lamps, the
lamp cradle must be as far
forward as possible (factory
default).
• For 2.0 or 3.0 kW lamps, move
the cradle to the rear position, i.e.,
approximately 1" closer to the
reflector.
2. Install Lamp
See 6.4, Replacing the Lamp &
Filter, Steps 7-11. Observe all
warnings, and wear protective
clothing and shielding.
Don't forget to properly mark the
"Lamp Installed" label on the lamp
door to indicate current lamp size.
