(1) Do not mount the probe with the tip higher than the probe base.<br />
3-2<br />
(2) If the probe length is 2.5 meters or more, the detector should be mounted vertically<br />
(no more than a 5° tilt).<br />
(3) The detector probe should be mounted at right angles to the sample gas flow or the probe<br />
tip should point downstream.<br />

When using the detector with pressure compensation, ensure that the flange gasket does not block the reference gas outlet on<br />
the detector flange. If the flange gasket blocks the outlet, the detector cannot per<strong>for</strong>m pressure compensation.<br />
Where necessary, make a notch in the flange gasket. Confirm the outside dimensions of the detector in Section 2.2 be<strong>for</strong>e<br />
installation.<br />
Figure 3.1 illustrates an example of the probe insertion hole.<br />
3.1.3 Installation of the Detector<br />
CAUTION<br />
• The cell (sensor) at the tip of the detector is made of ceramic (zirconia). Do not drop the<br />
detector, as impact will damage it.<br />
• A gasket should be used between the flanges to prevent gas leakage. The gasket material<br />
should be heatproof and corrosion-proof, suited to the characteristics of the sample gas.<br />
The following should be taken into consideration when mounting the general use detector:<br />
<br />
(1) Make sure that the cell mounting screws (four bolts) at the tip of the detector are not loose.<br />
If a dust filter (see Section 2.7.1) is used, make sure it is properly attached to the detector.<br />
Refer to Section 3.1.4 <strong>for</strong> installation of the dust filter.<br />
(2) Where the detector is mounted horizontally, the calibration gas inlet and the reference gas<br />
inlet should face downward.<br />
