Flow System
The Jerome 631-X's flow system is the crucial link between the sensor and the sample. For the
instrument to perform correctly, the flow system must be properly maintained. The user
maintainable components of this system are the intake filter (.25 inch fritware), two scrubber
filters and connecting tubing.
Check the Preventive Maintenance Calendar on page 18, for a suggested schedule for changing
fritware and scrubber filters. The Tygon™ tubing in the system must be free of crimps for proper
flow.

• Unscrew and remove the intake.
• Push the old fritware filter disc out of the intake with your
trimmer tool.
• Avoid touching the new fritware disc with fingers. Use
tweezers to insert the new fritware.
• Use the blunt end of the trimmer tool to seat the fritware disc
firmly against the inner ledge of the intake.
• Screw the intake back on the Jerome 631-X.
CAUTION:
The stem coming from the instrument onto which the outer intake housing is
attached must be securely held in place. If loose, the tubing inside the
instrument can become twisted when the intake housing is replaced. It may
be necessary to open the instrument and tighten the hold-down nuts inside
the instrument. Call AZI Customer Service at 800-528-7411, 601-470-1414,
