UVP TB-107 Transilluminator Ballast - Manual (Page 4)

10. Working wire by wire, repeat these steps until all wires have been transferred from the old to
the new ballast, taking care to match the location of the wires from the old to new ballasts.
Note that there are wires which must be transferred on both sides of the ballast.
Installation Procedure
1. Place the new ballast in the transilluminator in the same position as the old ballast, aligning
the two ballast mounting holes with the threaded studs coming from the transilluminator body.
2. Thread the two 1/4" lock nuts, removed earlier, onto the threaded studs. While carefully
flexing the fixed reflector panels out of the way, tighten the two lock nuts snugly.
3. Using a soft cloth, clean any fingerprints or other dirt off of the surface of the side reflector
panels prior to reinstallation.
4. The side reflector panels must be aligned with the main reflector panel during reinstallation.
a. A small metal tab (a) protrudes from the side reflector panel at a 90° angle. This tab
must slide on the inside (the bulb side) of the fixed reflector panel.
b. Another portion of the side reflector panel is bent at a tight 180° angle to create a
180° angle tab (b). This must be aligned with a metal tab protruding from the outside
(non-bulb side) of the fixed reflector panel.
