These procedures are applicable to full body systems manufactured after January 1993.

Tools required

• Phillips-head Screwdriver
• Pliers

Procedure

IMPORTANT: Always Disconnect Power from the System when Servicing.

1. To change a ballast, first determine which lamp number is defective. There is one ballast per lamp.
   • When entering the unit, for the "A" half (right side), the #1 lamp is next to the chrome handle and the #24 lamp is next to the hinge.
   • For the "B" half (left side), the #1 lamp is next to the hinge and the #24 lamp is next to the chrome handle.
2. Remove the four lamps behind the white interior handles. Remove one lamp on each side outside the white interior handles. Gently push up on each lamp and pull out from the bottom. Place these lamps in a safe area until repairs have been completed.
3. Loosen the four screws on the fan grill.
4. Remove ten parallel screws below fan and remove the piece of sheet metal.
5. Now determine which ballast is defective.
   • The top ballast is #1 and drives lamp #1.
   • The bottom ballast is #24 and drives lamp #24.
6. To remove the ballast first unplug the orange connectors on both sides of the ballast. Then straighten the tab on the side that has two tabs using pliers. Remove the defective ballast.
7. Mount the new ballast. Replace the grill, screws and lamps.
8. Apply power and test the system.
9. Please return all defective ballasts to: Ultralite Enterprises, Inc., 390 Farmer Court, Lawrenceville, GA 30045
