
Do not over-tighten the fittings.
15. If the service interval for this item has been exceeded, it may also be necessary to
clean the reaction cell as described in Section 11.3.9.
16. Leak check the system using the pressurized approach described in Section
11.3.12.2.

If necessary, tighten the fittings some more but do not over-tighten.
17. Restart the analyzer and pump and continue operation.
18. Recalibrate the analyzer after one hour (Section 9).

If Auto Zero is high or is changing/not constant, you may have to wait a day until
the silica gel is conditioned before recalibrating the instrument.
11.3.4. MAINTAINING THE EXTERNAL SAMPLE PUMP (PUMP PACK)
11.3.4.1. REBUILDING THE PUMP
The sample pump head periodically wears out and must be replaced when the RCEL
pressure exceeds 10 in-Hg-A (at sea level, adjust this value accordingly for elevated
locations).

A pump rebuild kit is available from the factory. Refer to the label on the pump for
the part number. Instructions and diagrams are included in the kit.

A flow and leak check after rebuilding the sample pump is recommended.

A span check and re-calibration after this procedure is necessary as the response
of the analyzer changes with the
RCEL
pressure.
