To install the lamp:
1.
Unpack the new lamp from its packing material without touching the bulb.
2.
Inspect the new lamp and lamp housing.
3.
Position the lamp so that the cut-out on the lamp base plate is at the 1 o’clock position, in
line with the alignment pin on the lamp housing.
4.
Gently push the lamp forward until it bottoms into position, and ensure that it is flush with
respect to the optics bench.
5.
Tighten the two captive screws, and then reconnect the lamp power connector.
6.
Close the door.
7.
Power-on the detector, and then wait 1 hour for the lamp to warm before resuming
operations.
Tip:
Cycling power to the detector (that is, powering-off and then powering-on the
instrument) initiates the verification procedures.
8.
In the console, select Maintain > Change lamp.
9.
In the Change Lamp dialogue box, click New Lamp.
10. In the New Lamp dialogue box, type the serial number of the new lamp (see the label
attached to the lamp connector wire), and then click OK.

Replacing the fuses
The 2998 PDA detector requires two 100 to 240 Vac, 50 to 60-Hz, F 3.15-A, 250-V (fast-blow), 5 ×
20 mm (IEC) fuses.
Suspect a fuse is open or otherwise defective when these events occur:
•
The detector fails to power-on.
•
The fan does not operate.
To replace the fuses:
Requirement:
Replace both fuses, even when only one is open or otherwise defective.
Notice:
To avoid diminishing the lamp's effectiveness, do not touch the glass bulb. If
the bulb requires cleaning, gently rub it with ethanol and lens tissue. Do not use
abrasive tissue. Do not apply excessive pressure.
Notice:
To prevent the lamp from binding and to ensure that it is properly seated in
the lamp housing, alternate between tightening the captive screws and pushing the
lamp forward.
Warning:
To avoid electric shock, power-off and unplug the PDA detector before
examining the fuses. For continued protection against fire, replace fuses with those
of the same type and rating only.
