Second Stage Reassembly
WARNING
: DO NOT attempt to use any other manufacturer's
part as a substitute for any XS Scuba part, regardless of
any similarity in shape, size, or appearance. Doing so may
render the product unsafe, and could result in serious injury
or death.
1. Install the exhaust valve(22) into the second stage housing(12)
by gently pulling the stem through the hole in the center of the
sealing area, until the barb has passed through and is seated
inside.
NOTE : Prior to installing the exhaust deflector(24), place it in
hot (120°-150°F) water for 2-3 minutes and allow it to soften.
2. Fit the exhaust deflector(24) over the top ridge of the second
stage housing, so that the two corners are securely seated, and
then stretch the lower portion down until it snaps securely into
place.
CAUTION:
Do not use a tool to install the exhaust deflector.
Doing so may cause serious damage to the seating flange,
requiring replacement of the housing.
3. Closely examine both sides of the white lever pad(9) to identify
that the mounting tabs on both legs are rounded on one side
and flat on the other. (See Fig. 23.) Hold the air barrel with the
flat cut facing down, and place the clip over the tube with the
rounded side facing toward the flange, so that one tab engages
in the hole next to it. Then, gently press the opposite leg into
place so the the other tab engages in the opposite hole. When
done correctly, the lever pad should rest flush against the flange,
with both tabs securely seated. (See Fig. 24.)
CAUTION : Do not stretch the legs of the lever pad, or at-
tempt to install it if damage has occurred.
4. Insert the stem of the LP seat(7) into the large end of the pop-
pet(6). DO NOT use adhesive.
5. Lubricate and install the small O-ring(5) over the groove on the
opposite end of the poppet, being careful to avoid stretching it
excessively. Closely examine the shape and features of the pop-
pet. (See Fig. 25.)
6. While holding the air barrel with the flat cut facing straight up,
guide the poppet into the tube, LP seat first, with the ears facing
straight down. (See Fig. 26.)
7. Closely examine both holes where the lever pad is installed, to
ensure that the ears of the poppet are properly aligned as shown
