Replacing the dia illumination lamp
Caution
• The lamp, the dia pillar illuminator, and the power supply must be used in specific
combinations. See page 55 to select the correct combination of the devices. Be sure to use
the specified lamps.
• When replacing the lamp, turn off the power switch and unplug the power cord.
• The lamp and its surroundings will be hot while the lamp is on and immediately after it is
turned off. When replacing the lamp, wait approximately 30 minutes after turning off the
lamp, and make sure that the lamp has cooled sufficiently before working.
• Do not touch the lamp glass with your bare hands. Fingerprints and other dirt on the lamp
may result in uneven illumination and reduce the service life of the lamp. Wear gloves when
handling the lamp.
• Securely close the lamphouse cover after replacing the lamp. Never turn on the lamp with
the cover removed.
