C. Reassembly and reinstallation of air fingers

Each air finger is made up of one inner plate, one outer plate and one finger manifold (Figure 4-13). Be sure to match the 'finger arrangement' identifier markings (T1, T2, etc.) on all the parts of each air finger during reassembly.

Figure 4-13. Air Finger

Parts

1.Reassemble the inner plate into the finger manifold (Figure 4-14). Keep your fingers clear to avoid pinching them.

The inner plate of an air finger will only go in one way because of its design, as shown in Figure 4-15.

2.Reassemble the outer plate by sliding it downward in the grooves on the side walls of the finger manifold. Keep your fingers clear to avoid pinching them.

3.Reinstall the air fingers (and blank plates) into the oven by sliding them into the channels on the rear oven wall, using the method shown in Figures 4-9 and 4-10. Sup- port the outer end of the finger (oven front), while pushing the base of the finger manifold portion along the chan- nels. Remember to reinstall each air finger, according to the identifiers marked on them. Each finger must go back into its original location.

Each oven is shipped with a finger arrangement label mounted inside the machinery compartment access panel. If this sticker is not legible, it is very important to mark the fingers as they were pulled out and to record them on a separate paper.
