11.1. GENERAL NOTES

CAUTION

THE OPERATIONS OUTLINED IN THIS CHAPTER MUST BE PERFORMED BY QUALIFIED

MAINTENANCE PERSONNEL ONLY.

PLEASE READ CHAPTER 11 OF THE M300E/EM MANUAL (P/N 04288) BEFORE ATTEMPTING THE FOLLOWING TROUBLE SHOOTING OR REPAIR PROCEDURES

CAUTION

RISK OF ELECTRICAL SHOCK. SOME OPERATIONS NEED TO BE CARRIED OUT WITH

THE ANALYZER OPEN AND RUNNING.

EXERCISE CAUTION TO AVOID ELECTRICAL SHOCKS AND ELECTROSTATIC OR

MECHANICAL DAMAGE TO THE ANALYZER.

DO NOT DROP TOOLS INTO THE ANALYZER OR LEAVE THOSE AFTER YOUR

PROCEDURES.

DO NOT SHORTEN OR TOUCH ELECTRIC CONNECTIONS WITH METALLIC TOOLS

WHILE OPERATING INSIDE THE ANALYZER.

USE COMMON SENSE WHEN OPERATING INSIDE A RUNNING ANALYZER.

The information found in Chapter 11 of the M300E/EM Operators Manual (P/N 04288) is applicable to the M300EU with the exceptions below.

CAUTION

ALWAYS ALLOW THE M300EU TO OPERATE FOR AT LEAST TWO HOURS AFTER ALL

REPAIRS HAVE BEEN FINISHED AND THE INSTRUMENTS CASE IS RE-CLOSED.

AT THE END OF THIS 2-HOUR STABILIZATION PERIOD MANUALLY INITIATE AN A-REF

MEASUREMENT (SEE SECTION 6.4.2)

Sample gas flows within the Nafion tubes while water vapor absorbs into the tubular membrane walls and is removed. Moisture permeating the tubing is carried away by a dry purge gas within the shell that flows countercurrent to the sample gas Aout 10.3. ELECTRONIC OPERATION10.3.1.
