Oxymitter 4000

Instruction Manual

IB-106-340 Rev. 3.0 December 2003

Use heat-resistant gloves and clothing when removing the probe. Do not at- tempt to work on these components until they have cooled to room tem- perature. Probe components can be as hot as 800°F (427°C). This can cause severe burns.

Disconnect and lock out power before working on any electrical components. There is voltage of up to 115 VAC.

Do not remove the cell unless certain it needs to be replaced. Removal may damage the cell and platinum pad. Go through the complete troubleshooting procedure to make sure the cell needs to be replaced before removing it.

1.Follow the instructions in paragraph

9-4a.1to remove the Oxymitter 4000 from the stack or duct. If removing an Oxymitter 4000/SPS 4000 assembly, follow the instructions in paragraph 9-4b.1.

2.If the probe uses the standard diffusion element, use a spanner wrench to re- move the diffusion element.

NOTE

To determine if the diffusion element needs to be replaced, refer to para- graph 9-2.

3.If equipped with the optional ceramic diffusion assembly, remove and dis- card the setscrews and remove the vee deflector (Figure 9-11). Use spanner wrenches from the probe disassembly kit (Table 11-1), to turn the hub free from the retainer. Inspect the diffusion element. If damaged, replace the ele- ment.

4.Loosen the four socket head cap screws from the cell and flange as- sembly and remove the assembly and the corrugated seal. The cell flange

has a notch that may be used to gently pry the flange away from the probe. Note that the contact pad inside of the probe will sometimes fuse to the oxy- gen sensing cell. If the cell is fused to the contact pad, push the cell assem- bly back into the probe (against spring pressure) and quickly twist the cell as- sembly. The cell and contact pad should separate. If the contact pad stays fused to the cell, a new contact/ thermocouple assembly must be in- stalled. Disconnect the cell and the thermocouple wires at the crimp con- nections and withdraw the cell with the wires still attached.

5.For units with integral electronics, dis- connect the entire electronics per paragraph 9-4c,steps 2 through 5.

6.Remove the four screws (7, Figure 9-3)from the probe finned housing. The probe and the probe head can now be separated.

7.If the contact assembly is damaged, replace the strut or the contact pad. In- structions for replacing the contact pad are in the cell replacement kit.

8.Remove and discard the corrugated seal. Clean the mating faces of the probe tube and retainer. Remove burrs and raised surfaces with a block of wood and crocus cloth. Clean the threads on the retainer and hub.

9.Rub a small amount of anti-seize com- pound on both sides of the new corru- gated seal.

10.Assemble the cell and flange assem- bly, corrugated seal, and probe tube. Make sure the calibration tube lines up with the calibration gas passage in each component. Apply a small amount of anti-seize compound to the screw threads and use the screws to secure assembly. Torque to 35 in-lbs (4 N·m).
