Caution

Be sure to do degreasing cleaning the O-ring before use. If degreasing cleaning is not carried out, there is a possibility that the sample heating tube will come off during measurement.

     For degreasing, wash the O-ring with neutral detergent well.

*Please wash for both new and used O-rings.

     Final rinse with distilled water.

*Inspect the O-ring for any damaged

*Don’t touch it directly with your hand.

Position the inlet ring in the direction shown below.

Tighten the screw to the extent that the sample inlet ring can be fixed.

*When the screw is completely tightened, the sample heating tube will not enter. Be careful.

     Put the sample inlet retainer on the desk. Put in the sample heating tube from above.

If you press the sample heating tube twisting, it will be easier to put in.

*Be careful not to break the sample heating tube.

            Install the Teflon joint and the mercury collection tube to the sample heating tube.
Disassemble the Teflon joint, pass the sample heating tube through the box nut, washer, O-ring and joint in this order and tighten the nut.
Here, do not insert the joint too deep so that the position can be easily adjusted later.

*    The thread on the Teflon joint is easily damaged. Ensure to verify that the nut turns smoothly. If the box nut does not correctly engage the thread, it could result in leaking.

        Wipe the outside of the sample heating tube and the mercury collection tube with alcohol.
*If hand sweat is attaching, there is a possibility that the sample heating tube will be broken during heating.

          Insert the sample heating tube.
Slowly insert the sample heating tube into the sample inlet while twisting it gently to the left and right.

*    Pushing it too forcefully could result in the heater being deformed or disconnection.

           Pass the mercury collection tube through the H3 heater and push it until the sample inlet touches the reducing joint.

           Fix the sample inlet retainer in place.
Tighten the screws with the supplied hex wrench.

           Adjust the position of the mercury collection tube. Align the end of the heater and the dent of the mercury collection tube. Adjust the position by adjusting the insertion depth of the Teflon joint.
Tighten the Teflon joint securely. In particular, the reducing joint must be tightened lightly with a hand at first and then re-tightened with a wrench by about ½ turn.

*    The joint may be broken if excessively tightened.

           Connect the elbow joint to the branch pipe on the sample inlet.

           Install the pipe heater cover and sample heater tube retainer. Close the front cover and install the top cover.

           Turn ON the power of the MA-3000 and perform the check of flow path to make sure that there is no leak.
