6. Loosen the two captive Phillips head screws from the standard desiccant cartridge, and lift
the cartridge straight up and out of the instrument.
Note If the standard desiccant cartridge is stored in a dry box or sealed bag (you can
use the bag the purge cartridge came in), the cartridge can be reused.
7. Remove and discard the large O-ring.
Note Be careful not to drop the sealing O-ring into the desiccant compartment.
8. Open the purge kit and then open the sealed desiccant packet (must be sealed to keep the
desiccant dry).
9. Remove the O-ring from the packet and install it on the instrument base plate (see the
previous image). Press (rather than roll) the new O-ring into place to be sure it is properly
seated in the groove.
10. Remove the desiccant cartridge with purge fittings from the packet, insert the cartridge in
the desiccant compartment, make sure it is seated properly over the O-ring and then
secure it using the two screws.
