10.5.1.2. Replacing the UV Lamp

1.Turn off the analyzer.

2.Disconnect the UV lamp from its power supply.

•You can find the power supply connector by following the two, white UV Lamp power supply wires from the lamp to the power supply.

3.Loosen, but do not remove the two UV lamp bracket screws, and the large brass thumbscrew located on the shutter housing (see Figure 10-1) so that the lamp can be moved.

NOTE:

DO NOT grasp the UV lamp by its cap when changing its position (see Figure 10-1).

Always grasp the main body of the lamp.

4.Remove the UV Lamp by pulling it straight up.

5.Insert the new UV lamp into the bracket.

6.Tighten the two UV lamp bracket screws, but leave the brass thumb screw un-tightened.

7.Connect the new UV lamp to the power supply.

8.Turn the instrument on and perform the UV adjustment procedure as defined in section 10.5.1.1 of this addendum
