Internal Filters
• Replace the internal filters after six (6) months of use, or as needed.
• Press the power OFF button and unplug the power cord.
• Remove the two (2) side screws from the intake end of the instrument and open the case.
• Carefully disconnect the Tygon tubing from both ends of the filters and discard the old
filters.
CAUTION:
Scrubber filters contain Resisorb. Used filters, especially the scrubber
filter may contain hydrogen sulfide also. Use proper methods when
disposing of used filters. Call AZI Customer Service at 800-528-7411,
601-470-1414, or e-mail [email protected] for a copy of the Resisorb
MSDS or for other questions.
• Connect the new filters to the Tygon tubing, ensuring all straight hose barbs point toward
the intake/pump corner of the case and elbow hose barbs point toward the sensor housing as
shown in the illustration.
Push the Tygon as far as it will go onto the filter fittings.
• Push the filters into the mounting clips.
• Remove any crimps or twists in the tubing and ensure that tubing connections are secure. If
the tubing is loose, readings may not be accurate. Replace any tubing that has deteriorated
due to heat and/or age.
• Close the case and replace the screws.
• Dispose of all filters in accordance with state and federal environmental regulations.
