CAUTION: Do not apply bending force to the lamp bulb. Do not touch
the bulb with bare fingers or allow it to contact dirty or greasy surfaces.
Contaminants can be burned into the quartz envelope, causing
premature bulb failure.
3. Clean any deposits from the surface of the bulb (see “Cleaning Guidelines” on page
79).
Figure 21. Removing or Replacing the Bulb
4. To replace a lamp bulb in the reflector, hold it near the middle and insert the tip
of the bulb into the retaining hole of one end reflector. Apply pressure in the
direction of the length of the bulb, moving it toward the end that is inserted. This
will allow the free end to clear the end reflector. Gently slide the end of the bulb
down to the retaining hole and allow it to pop into position.
Reflector Removal/Replacement
Replace the reflector only if it becomes dull and its surface cannot be cleaned
successfully, or if severe arcing is apparent (dark or burned spots).
1. Remove the screen assembly and the bulb.
2. Remove the six flat head screws and lift the reflector out.
