b. 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.
c. Remove and discard the large O-ring.
d. Open the purge kit and the sealed desiccant packet.
e. Remove the O-ring from the packet and install it on the instrument base plate (see
previous image). Press (rather than roll) the new O-ring into place to be sure it is
properly seated in the groove.
f. Remove the desiccant cartridge with purge fittings from the packet, insert the
cartridge in the desiccant compartment, ensure that it is seated properly over the
O-ring, and then secure it using the two screws.
Note the correct orientation of the cartridge. You should be able to read the label on
the cartridge from the front of the instrument when the cartridge is installed.
