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.
