SeaAir Regulator (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.) Fig. 28 – Lever Installation Fig. 29 – Correct Lever Orientation Fig. 30 – Poppet Alignment/ Preset Tool NOTE: To better control the orientation of the poppet inside the air barrel while the lever is being installed, 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 fitting, which can crack the wall of the second stage housing, requiring its replacement. Fig. 31 – Valve Assembly Completely Installed 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 SeaAir Regulator Service and Repair Manual 22
Service & Repair Manual the polished cone facing in. Using a small wooden or plastic down, press the orifice in so that it rests against the threads inside the air barrel. (See Fig. 33.) 16. Turn the adjustment knob counterclockwise until it stops. 17. Apply a medium blade screwdriver to the slotted head of the orifice inside the air barrel, and turn it clockwise while closely watching the lever. When the lever starts to drop, stop – do not turn the orifice any further. This will indicate that the orifice has made contact against the LP seat. (See Fig. 34.) Fig. 32 – Installing Retaining Clip NOTE: To pre-set the orifice at exactly the correct depth inside the air barrel, XS Scuba recommends using the Poppet Align/ Orifice Preset Tool (P/N 20-785-400), available from Peter Built Co. Complete instructions are provided with the tool. (See Fig. 35.) 18. Lay the diaphragm(14) inside the housing, directly over the lever with its raised surface facing up, and then the thrust washer(15). 19. Fit the front cover(16) inside the housing so that it seats directly over the diaphragm. Turn it as needed to align the logo straight between the inlet and adjustment knob. (See Fig. 36.) 20. Mate the retaining ring(17) over the front cover and into the housing, and turn it clockwise to engage the threads. While holding the front cover secure with one hand, tighten the retaining ring until snug with the other. Be careful to avoid over-tightening. 21. Install the mouthpiece(23) onto the housing, correctly oriented with the top facing up. Fasten a tie-strap(21) over the mouthpiece with the locking tab facing toward the inlet coupling, and cinch it snug. Trim the excess material close to the locking tab.
