INSTALLATION

The compact JIC box is provided with flanges, each having two 1/4" mounting holes. Locate the box to within about six feet of the sensor, if possible. Avoid locations close to a source of combustibles such as the vent pipe of an oil quench tank, or a natural gas fitting that could develop a leak. Because the reference air pump aspirates air from its immediate vicinity to pump to the probe reference air fitting, it is possible to experience a significant error in measurement due to reaction of the combustible with air inside the probe. The result is a low reading of percent carbon, which will cause the controls to add excess natural gas and overcarburize your work piece. A purge valve maybe is connected to power through terminals 1054 and 1055 as shown in Fig.1. This will accelerate the recovery by rapidly displacing the burnoff air with furnace atmosphere.
