BULB INSTALLATION AND OPERATION (continued)
MOVE THIS CONTROL SECTION around the two screws until the hot spot is centered
in the brown circle of the reflector. After the hot spot is centered, tighten the two thumb screws to lock
this adjustment section and turn the center focus control section counterclockwise to obtain the brightest
light with the best light distrubution. Rotate the lens spot focus control knob, located on the front of the
lens mechanism, to obtain the sharpest edge possible on the projected spot.
REPLACE THE REAR COVER PLATE over the bulb adjustment control mechanism.
Secure using the push-type fasteners.
THE FOLLOW SPOT may be turned off at the lamphouse or the power supply, whichever
is most convenient to the operator. It is recommended that the circuit breaker on the rear of the power
supply be placed in the "OFF" position, to function as a line switch, when the spot is off for any extended
period of time.
WHEN TRANSPORTING, or if the bulb may be subjected to a hard shock when moving
to another location, remove the assembled metal halide bulb from the lamphouse by reversing the
installation procedures. If the control section of the bulb adjustment is not changed, the bulb should be
able to be replaced without any necessity to repeat the aligning procedures.
THE METAL HALIDE BULB ignites better when cold. After extinguishing the bulb,
allow at least one minute cooling before attempting re-ignition.
EXPECTED BULB LIFE is 750 hours, but because of manufacturing tolerances, some
bulbs may lose color quality before this period.
BULB LIFE can be maximized by avoiding repeated ignitions. Allow the lamp to burn
throughout the spotlight's use cycle, dousing out with the masking shutter blades or fadeout mechanism
as required.
RECORD the elapsed time meter reading when replacing a bulb.
