Model 5081FG

5.Use high temperature material (alu- mina wool) to seal around the probe during insertion. This prevents hot gases from escaping or cold air from entering the stack or duct.

6.Initially insert the probe to a depth of 3 in. (76.2 mm) or 1/2 the depth of the stack or duct refractory, whichever is greater.

After initial insertion, do not insert the probe at a rate exceeding 1 in. per mi- nute (25.4 mm per minute) or damage to the probe may result due to thermal shock.

7.After initial insertion, insert the probe at a rate of 1 in. (25.4 mm) per minute until the probe is fully inserted.

8.Install anti-seize compound on the pipe threads and screw the probe into the process flange or adapter.

9.If insulation was removed to access the duct work for probe mounting, make sure the insulation is replaced after- ward. See Figure 2-4.

If the ducts will be washed down dur- ing outage, MAKE SURE to power down the probes and remove them from the wash area.

c.Locating Model 5081 Transmitter

1.Ensure the Model 5081 Transmitter is easily accessible for maintenance and service and for using the infrared re- mote control (if applicable).

Do not allow the temperature of the Model 5081 Transmitter exceed 65°C (149°F) or damage to the unit may result.

NOTE

Use anti-seize compound on threads to ease future removal of probe.

The electrical conduit port should be facing down for a horizontal probe in- stallation. See Figure 2-4.In vertical probe installations, orient the probe so the system cable drops vertically from the probe. Ensure the electrical conduit is routed below the level of the terminal block housing. This drip loop minimizes the possibility that moisture will accu- mulate in the housing.

2.The ambient temperature of the trans- mitter housing must not exceed 65°C (149°F). Locate the electronics in an area where temperature extremes, vi- bration, and electromagnetic and radio frequency interference are minimal.

3.Locate the Model 5081 Transmitter within 150 ft (45.7 m) of the oxygen probe due to wiring and signal considerations.
