BECAUSE OF MANUFACTURING TOLERANCES, it may be necessary to reposition the
reflector after having centered the aligning cord in the test aperture. To do so, loosen the #8 screws (Figure 2,
Item 54) from the back of the reflector flange and alternately tighten and loosen the spring-loaded allen head
reflector mounting screws (Figure 2, Item 8) to achieve the desired “single string” image on the reflector.
Retighten the #8 screws, and secure the locknuts, after completing the alignment. DO NOT overtighten to the
point where the lockscrews can warp the reflector flange.
ILLUSTRATIONS showing the correct and incorrect aligning cord images appear above.
The “CORRECT” illustration shows the cord covering its reflected image. The “INCORRECT” drawing,
showing the cord and its reflected image, denotes a small degree of misalignment. Observe the results of the
above adjustments by carefully watching the shifting position of the cord’s reflection.
UPON COMPLETION of the alignment procedure, remove the cord and its associated fix-
tures, and restore operation of the changeover/fire shutter douser. Store the alignment kit parts in a secure
location in the booth; replacement of a reflector will require a second alignment. Rotate the focus control knob
to center the anode support column in its travel path prior to installing the xenon bulb.
