Changing the Desiccant
CAUTION
ATTENTION
Expect to change the desiccant in the spectrometer approximately every
five years. Old, used desiccant releases moisture.
In regions experiencing high humidity levels we recommend that you
change the desiccant more often, and that you monitor the internal
humidity of your instrument using the Humidity Shield (refer to page 82)
regularly.
Attendez-vous à changer le dessicant dans le spectromètre environ tous
les cinq ans. Ancien, le dessiccateur utilisé libère de l'humidité.
Dans les régions où le taux d'humidité est élevé, nous vous
recommandons de modifier le déshydratant plus souvent et de surveiller
l'humidité interne de votre instrument à l'aide de l'humidité (voir page
81) régulièrement.
The desiccant change interval is set in the Desiccant change due in (days) option on the
Setup Instrument BeamPath tab in Spectrum software (Figure 82).

If the desiccant change due date has passed, a warning will be displayed in the Status Bar
and in the table on the Setup Instrument BeamPath tab.
The warning is displayed until you update the software that the desiccant has been changed.
To reset the desiccant change interval, select the current value, click Changed to clear any
warning messages.
You may also be prompted to change your desiccant during the Component Checks.
To replace the desiccant, you will require the desiccant replacement kit (part number
L1600244). The kit contains a wrench and two bags: one large and one small.
Inspect the humidity indicator card in the plastic bag containing the larger of the two bags. If
the card is pink it indicates moisture in the bag, and you should discard the desiccant pack.
Only use the replacement desiccant bag if the indicator is blue.
