SeaAir Regulator Service and Repair Manual
(see Fig. 27). While holding the air barrel with the flat cut
facing up, insert one leg of the lever(18) into one hole, so that
it engages with the poppet (see Fig. 28). Being careful to avoid
stretching or bending the lever, rotate it over the air barrel until
the opposite leg engages with the opposite side. Check to ensure
that the lever is properly seated on both sides, securely engaging
the poppet ears. (See Fig. 29.)
NOTE:
To better control the orientation of the pop-
pet inside the air barrel while the lever is being in-
stalled, XS Scuba recommends using the Poppet Align/
Orifice Preset Tool (P/N 20-785-400), available from
Peter Built Co. (See Fig. 30.)
8. Apply a light coat of lubricant to both ends of the poppet
spring(4), and place the spring inside the air barrel, over the
small end of the poppet.
9. Insert the small end of the shuttle cap(3) into the end of the
poppet spring.
10. Install the O-ring(2) onto the adjustment knob(1). Mate the
adjustment knob directly over the shuttle cap, and screw the
knob clockwise onto the air barrel approximately 3-4 full turns.
11. While holding the second stage housing right side up with the
front facing you, slide the valve assembly into the opening in
the right side of the housing. Gently depress the lever, and then
slide the valve assembly through the opening on the inlet side.
Be careful to ensure that both lever arms fit squarely between
the two flanges inside the housing, and then slide fully in place
so that the lever pad is seated flush. (See Fig. 31.)
12. Install the retaining clip(13) over the groove of the adjustment
knob inside the housing, so that it snaps securely into place.
(See Fig. 32.)
13. Install the O-ring(19) over the threaded inlet of the air barrel,
being careful to avoid stretching it or rolling over the threads.
Use a smooth instrument to ensure that it is seated at the base of
the threads, against the wall of the housing.
14. Mate the inlet fitting(20) over the threads of the air barrel, and
turn it clockwise by hand until finger snug. Apply a n" open end
wrench to tighten it further by exactly 8 turn.
CAUTION
: Be careful to avoid overtightening the inlet fit-
ting, which can crack the wall of the second stage housing,
requiring its replacement.
15. Install the O-ring(11) onto the head of the adjustable orifice(12)
and carefully insert the orifice into the inlet of the air barrel with
