4-12 Maintenance Procedures
Installing the new lamp
Before you begin:
1. Unpack the lamp from its packing material.
2. Record the serial number, which is located on a label attached to the
lamp’s connector wire, following the procedure on page 4-13 .
To install the new lamp:
1. Position the lamp cartridge, and insert it in the housing.
Tip:
No additional alignment is required.
2. Push the lamp forward gently, until it bottoms into position.
3. Tighten the two captive screws.
4. Reconnect the lamp’s power connectors.
Tip:
The bottom connector locks into place.
5. Close and secure the lamp access door.
6. Connect the power cord, and start the detector.
Allow at least 60 minutes for the lamp to warm before resuming
operations.
7. Record the new lamp’s serial number (see the next section).
Warning:
To avoid exposing your eyes to harmful ultraviolet
radiation, wear eye protection that filters ultraviolet light, and
keep the lamp in the housing during operation.
Caution:
Do not touch the glass bulb on the new lamp. Dirt or skin oils
on the bulb affect detector operation. If the lamp needs cleaning, gently
clean the bulb with ethanol and lens tissue. Do not use any abrasive
tissue or apply excessive pressure.
Warning:
Make sure electrical power to the detector is off and the
power cord is disconnected.
