5. Disconnect the black power connector from the power supply by turning the connector
and then carefully pulling the two halves of the plug apart.
6. Loosen the brass nut on the UV enclosure. The nut should only be finger-tight, and a
wrench should not be necessary.
7. Slowly slide the UV lamp out of the enclosure.
8. Put on the glove provided with the new UV lamp, to avoid leaving fingerprints on the quartz
window of the lamp. Remove the new lamp from the packet and the nut and ferrules from
the zip-top bag.
9. Slide the nut up the lamp housing (toward the connector cord), and then slide the ferrules
up the lamp housing, until they are level with the black heat shrink tubing. Be careful when
inserting the lamp into the Analyzer as the nut and ferrules may slide off. Refer to Figure 32
and Figure 33 for proper orientation of the ferrules.
