4-22 Maintaining the Detector
3. Record the serial number located on a label attached to the lamp
connector wire using the procedure in “Recording the new lamp serial
number” on page 4-23.
Requirement: Make sure the detector is powered-off and the power cord is
disconnected.
To install the new lamp:
1. Position the lamp so the cut-out located on the lamp base is at the 1
o’clock position (see the figure below), in line with the alignment pin on
the lamp housing. There is no additional alignment required.
2. Gently push the lamp forward until it bottoms into position.
3. Tighten the two captive screws.
4. Reconnect the lamp power connector.
5. When ready to resume operation of the detector, reconnect the power
cord and power-on the unit. Allow at least 5 minutes for the lamp to
warm up before resuming operations.
Tip: The instrument firmware automatically delays operation for 5
minutes to allow the lamp to warm up after it has been reignited.
Caution: When you change the lamp, always power-off the detector. After
installing a new lamp, power-on the detector and always wait at least 5
minutes for the new lamp to warm up.
