4. While holding the vane switch in place, set the box bottom on a flat surface with the open side facing
down and the switch at 12 o'clock. Guide the tool holding the circlip into the outlet boss, with the top
surface of the tool held flush against the ceiling, directly behind the vane. Press the circlip evenly onto
the groove of the vane stem until it snaps audibly into place (see Fig. 11). Remove the tool and exam-
ine closely to ensure the circlip is seated completely inside the groove. Remove and reinstall the
circlip if necessary.
CAUTION: It is important to ensure that the vane adjustment switch, o-ring, and circlip are cor-
rectly installed in order to maintain the watertight integrity of the box bottom assembly. Improper
installation may result in flooding of the second stage.
5. Install the exhaust valve diaphragm (22) into the box bottom by gently pulling the stem through the
hole in the center of the support spokes, until the barb has passed through and is securely seated
inside the box bottom. Carefully snip off the excess material of the stem.
6. Install the exhaust tee (6) onto the box bottom by fitting it over one upper corner of the seating flange
and then stretching it over the other. Firmly press the lower portion of the tee onto the flange until it is
completely seated.
CAUTION: Do not use a tool to install the exhaust tee. Doing so may cause serious damage to the
seating flange, requiring replacement of the box bottom.
7. Install a new crown o-ring (33) and inlet fitting o-ring (30). Carefully insert the threaded end of the
crown into the hose connection end of the inlet fitting (see Fig. 12a). Gently press it in further with
the blunt end of the extraction tool (P/N 1094-36) until it stops (see Fig. 12b).
