Maintenance
Replace the Desiccant
If your instrument is not equipped with a purge kit, or if the purge is turned off, you must monitor the
humidity level inside the spectrometer. Replace the desiccant when the paper humidity indicator turns
pink (can be light pink or almost white). Replace the paper humidity indicator each time you replace the
desiccant.
Replacing the desiccant requires you to remove the desiccant cartridge and replace the desiccant
canisters and the O-ring.
TOOLS NEEDED
Before you begin, you will need the following:
l
Desiccant replacement kit
l
A 0.05-inch hex key
l
A #2 Phillips head screwdriver
l
Gloves, finger cots, or laboratory tissue (to handle the humidity indicator)
WARNING
Avoid explosion hazard.
Before opening the desiccant compartment, turn off the instrument power, unplug
the power cord and remove all accessories and samples from the system. Entry of
flammable liquids or gases into the desiccant compartment is an explosion hazard.
If such entry occurs, contact us immediately and do not apply power to the
instrument until the condition has been corrected.
NOTICE
Make sure nothing falls into the instrument while the desiccant cover is removed.
WARNING
Replace the desiccant only with replacement parts supplied by us.
