Replace the internal filters after six (6) months of use, or as needed.
The AG filter should be replaced every six (6) months or every 500 samples,
whichever comes first, based on your instrument usage schedule.

Remove the two (2) side screws from the intake end of the instrument and open the case.

Carefully disconnect the Tygon

filters.

Replace the old filters with new filters, oriented as shown in the diagram above.

Remove any crimps or twists in the tubing and ensure that tubing connections are secure. If

If the AG filter is replaced, the new filter must be acclimated to the system by performing a
