the Analyzer as the nut and ferrules may slide off. Refer to Figure 34 and Figure 35 for proper
orientation of the ferrules.

10. Carefully slide the lamp assembly into the enclosure. Stop if you feel any resistance, and realign the
lamp in the reactor. Make sure the black heat tubing is flush against the brass-colored nut.
11. Tighten the brass-colored nut finger-tight. While tightening the nut, make sure the heat shrink tubing
