To replace the filter, proceed as follows:
1) Unscrew the luer fitting from one side of the the filter
in a counter clockwise direction, detach the tubing
from the other side then remove the hydrophobic

direction of flow orientation is maintained. This can be
easily identified by position of yellow label on filter,
i.e. facing instrument.
2) Fit a new In-line Hydrophobic Filter (Part No. 66484).
Note that the filter should be fitted with the yellow
label facing the instrument.
3) Attach the luer fitting, with sample line attached, to
the mating side of the filter then tighten in a clockwise
direction to secure. Do not overtighten the fitting.
4) Attach the sample line to the other side of the filter
making sure that it is securely fitted.
