See Figs. 14a–14h.
NOTE: When re-inserting the faceseal into the inner shield, it is important to align the square corner of the
faceseal's shiny black plastic perimeter, shown in Fig. 14a, into the slot of the inner shield. If assembled correctly,
the hole shown in Fig. 14c should be two half circles, filling the open hole.
