3 General Safety & Installation
Safety
This section summarizes the basic precautions applicable to all analyzers. Additional precautions specific to individual analyzer
are contained in the following sections of this manual. To operate the analyzer safely and obtain maximum performance follow
the basic guidelines outlined in this Owner’s Manual.
Caution: This symbol is used throughout the Owner’s Manual to Caution and alert the user to recommended safety and/or
operating guidelines.
Danger: This symbol is used throughout the Owner’s Manual to identify sources of immediate Danger such as the presence of
hazardous voltages.
Read Instructions: Before operating the analyzer read the instructions.
Retain Instructions: The safety precautions and operating instructions found in the Owner’s Manual should be retained for
future reference.
Heed Warnings Follow Instructions: Follow all warnings on the analyzer, accessories (if any) and in this Owner’s Manual.
Observe all precautions and operating instructions. Failure to do so may result in personal injury or damage to the analyzer.
Heat: Situate and store the analyzer away from sources of heat.
Liquid and Object Entry: The analyzer should not be immersed in any liquid. Care should be taken so that liquids are not
spilled into and objects do not fall into the inside of the analyzer.
Handling: Do not use force when using the switches and knobs. Before moving your analyzer be sure to disconnect the
wiring/power cord and any cables connected to the output terminals located on the analyzer.
Maintenance
Serviceability: Except for replacing the oxygen sensor, there are no parts inside the analyzer for the operator to service.
Only trained personnel with the authorization of their supervisor should conduct maintenance.
Oxygen Sensor: DO NOT open the sensor. The sensor contains a corrosive liquid electrolyte that could be harmful if touched
or ingested, refer to the Material Safety Data Sheet contained in this Owner’s Manual. Avoid contact with any liquid or crystal
type powder in or around the sensor or sensor housing, as either could be a form of electrolyte. Leaking sensors should be
disposed of in accordance with local regulations.
Troubleshooting: Consult the guidelines in section 8 for advice on the common operating errors before concluding that your
analyzer is faulty. Do not attempt to service the analyzer beyond those means described in this Owner’s Manual.
Do not attempt to make repairs by yourself as this will void the warranty, as detailed by section 9, and may result in electrical
shock, injury or damage. All other servicing should be referred to qualified service personnel.
Cleaning: The analyzer should be cleaned only as recommended by the manufacturer. Wipe off dust and dirt from the outside
of the unit with a soft damp cloth then dry immediately. Do not use solvents or chemicals.
Nonuse Periods: Disconnect the power when the analyzer is left unused for a long period of time.
Installation
Gas Sample Stream: Ensure the gas stream composition of the application is consistent with the specifications and review the
application conditions before initiating the installation. Consult the factory to ensure the sample is suitable for analysis.
Contaminant Gases: A gas scrubber and flow indicator with integral metering valve are required upstream of the of the
analyzer to remove interfering gases such as oxides of sulfur and nitrogen or hydrogen sulfide that can produce false readings,
reduce the expected life of the sensor and void the sensor warranty if not identified at time of order placement. Installation of a
suitable scrubber is required to remove the contaminant from the sample gas to prevent erroneous analysis readings and
