6. MAINTENANCE
SECTION FOUR
SURFACE LAMP
To change the surface lamp, first remove the lamp house cover. The bulb is
located at the bottom of the lamp house.
To remove the bulb, grasp and lift the bulb ejection wire lever to eject bulb.
Remove the new replacement bulb from its box, Do not touch the small bulb
inside the reflector housing. Flip the bulb ejector wire back down, line up the
two lamp pins with the slots in the socket and slide the new bulb straight
down into place.
Switch main power on and set lamp intensity to low.
Verify that the lamp is working and illuminating the fiber optic cables.
If the small glass bulb inside the reflector housing is accidentally touched,
wipe the bulb immediately by swabbing with methanol. The lamp operates at
a high temperature and any finger marks will be “fired” into the surface of the
quartz reducing the output and life of the lamp.
Surface bulb ejector lever
Use the ejector lever when
removing the lamp to avoid
twisting the lamp and
cracking the ceramic socket.
