5.In vertical installations, ensure the system cable drops vertically from the Oxymitter 4000 and the conduit is routed below the level of the electronics housing. This drip loop minimizes the possibility that moisture will damage the electronics (Figure 2-8).

6.If the system has an abrasive shield, check the dust seal gaskets. The joints in the two gaskets must be staggered 180°. Also, make sure the gaskets are in the hub grooves as the Oxymitter 4000 slides into the 15° forcing cone in the abrasive shield.

7.Insert probe through the opening in the mounting flange and bolt the unit to the flange. When probe lengths selected are 9 to 18 ft (2.74 to

5.49 m), special brackets are supplied to provide additional support for the probe inside the flue or stack (Figure 2-6).

NOTE

If process temperatures will exceed 392°F (200°C), use anti-seize compound on stud threads to ease future removal of Oxymitter 4000. For ambient temperatures that will exceed 185°F (85°C), we recommend the remote mounted electronics option.
