10.Push down on the back plate of the strut to make sure you have spring tension and then tighten the three screws on the back plate.

11.Replace the CAL and REF gas silicon tubes.

12.For units with integral electronics, in- stall the entire electronics per para- graph 9-4c,steps 7 through 13.

13.For units with remote electronics, install the probe head as follows:

(a)See Figure 9-9.Make sure that the O-ring (10) is in good condition. Seat the O-ring in the mating groove of the probe (6).

(b)Insert the probe signal cables (8 and 9, into the housing (21).

(c)Turn the conduit ports of the housing (21) to the CAL and REF gas ports side of the probe (6) and position the housing on the probe

(d)Install and tighten four screws (12, Figure 9-4).

(e)Reconnect the probe signal cables (8 and 9) to the probe signal and

heater wire connectors, Figure 9-9.Make sure the connectors are se- cure.

(f)Install and tighten cover.

14.Follow the instructions in paragraph

9-4a.2to install the Oxymitter 4000 into the stack or duct. If installing an Oxy- mitter 4000/SPS 4000 assembly, follow the instructions in paragraph 9-4b.2.

i.Cell Replacement

This paragraph covers oxygen sensing cell replacement. Do not attempt to replace the cell until all other possibilities for poor per- formance have been considered. If cell re- placement is needed, order the cell replacement kit (Table 11-1). Refer to Figure 9-3or Figure 9-4to view the compo- nent parts of the Oxymitter 4000.

The cell replacement kit (Figure 9-10)con- tains a cell and flange assembly, corrugated seal, setscrews, socket head cap screws, and anti-seize compound. The items are carefully packaged to preserve precise surface finishes. Do not remove items from the packaging until they are ready to be used. Spanner wrenches and hex wrenches needed for this procedure are part of an available special tools kit (Table 11-1and Figure 11-2).
