connections on the side of the sensor flow housing (unless otherwise indicated, either fitting can serve as inlet or vent) and are
intended to operate at positive pressure regulated to between 5-30 psig.
Outlet Pressure: The sample gas vent pressure should be atmospheric.
Installation
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 the Owner’s Manual appendix. 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.
Mounting: The analyzer is approved for indoor use, outdoor use requires mounting in a secondary enclosure with the
appropriate NEMA rating. Mount as recommended by the manufacturer.
Power: Supply power to the analyzer only as rated by the specification or markings on the analyzer enclosure. The wiring that
connects the analyzer to the power source should be installed in accordance with recognized electrical standards and so they
are not pinched particularly near the power source and the point where they attach to the analyzer. Never yank wiring to
remove it from an outlet or from the analyzer.
Operating Temperature: The maximum operating temperature is 45º C.
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
