Replacing The Uv Lamp - GE Sievers 900 Series Operation And Maintenance Manual

6. Remove the new reagent container(s) from the packaging. Record the expiration date of
the acid and oxidizer and the volume of the oxidizer in the Notes column on the
Maintenance Worksheet (see Table 18 on page 193); you also will need to enter these
dates into the Analyzer later.
7. For each reagent, follow these steps:
• Locate the supply line for the reagent you are replacing, indicated by the Acid or
Oxidizer label on the tubing.
• Attach the appropriate PEEK nut to the reagent container and tighten finger-tight.
• Press the green button all the way in to open the valve on the reagent container. Refer
to the labeling on the container for proper positioning.
• Slide the container into the reagent enclosure, with the valve pointing down and
toward the front of the reagent enclosure. Be careful to move tubing and wires out of
the way while sliding the cartridges into the enclosure, so you do not inadvertently
crimp tubing or loosen cable connections.
8. Replace the reagent enclosure cover and tighten the set screw until it is finger-tight.
9. If you need to replace other consumables, follow the procedures listed in the appropriate
sections of this chapter. Otherwise, close and latch the Analyzer door.
10. Power the Analyzer on.
11. Enter the installation and expiration dates for the reagents by following the procedures in
"Setting the Installation or Expiration Date for New Consumables" on page 190 to ensure
that the Analyzer correctly tracks the life of the new reagents.
12. To reduce the possibility of bubbles, perform a flush of the reagent syringes before
resuming normal operation. Refer to "Flushing the Reagent Syringes" on page 191 for
details.

Replacing the UV Lamp

The intensity of the UV lamp, particularly the emission of short-wavelength radiation, decreases
over time. Replace the lamp after every six months of operation.
