4.If using the optional ceramic diffusor element, the vee deflector must be cor- rectly oriented. Before inserting the probe, check the direction of flow of the gas in the duct. Orient the vee deflector on the probe so that the apex points upstream toward the flow (Figure 2-2). This may be done by loosening the setscrews, and rotating the vee de- flector to the desired position. Retighten the setscrews.

5.In horizontal installations, the probe junction box should be oriented so that the system cable drops vertically from the probe junction box. In a vertical in- stallation, the system cable can be ori- ented in any direction.

6.If the system has an abrasive shield, check the dust seal packings. The joints in the two packings must be staggered 180°. Also, make sure that the packings are in the hub grooves as the probe slides into the 15° forcing cone in the abrasive shield.

NOTE

If process temperatures will exceed 392°F (200°C), use anti-seize com- pound on stud threads to ease future removal of probe.

7. Insert probe through the opening in the mounting flange and bolt the unit to the flange. When probe lengths selected

are 9 or 12 ft (2.75 or 3.66 m), special 2 brackets are supplied to provide addi-

tional support for the probe inside the flue or stack. See Figure 2-1,sheet 5.

NOTE

Probe Installation

To maintain CE compliance, ensure there is a good connection between the chassis of the probe and earth.
