Remove the ballast/power supply insulator. To do this, tilt the insulator away from the front wall of
the chassis and the ballast mounting standoffs. Then lift the insulator out of the projector.
You are left with the bare chassis.
Assembly Notes
•
Position the ballast/power supply insulator in the chassis so that the holes in the bottom of the
insulator align with the ballast mounting slots and power supply standoffs that protrude from the
floor of the chassis. Then press the insulator over the ballast mounting standoffs on the front of
the chassis.
WARNING
The insulator must always be installed between the ballast and power supply and the
chassis. Inspect the gasket closely whenever the ballast or power supply is removed. Never
use a gasket with holes or tears.
