14. Using a narrow shafted, slotted blade screwdriver, slowly turn
the ORIFICE (31) clockwise into the VALVE HOUSING (26) until
the Knife Edge is barely contacting the POPPET SEAT (25). This
is indicated by the DEMAND LEVER (27) beginning to drop. As
soon as it does, stop turning the ORIFICE and turn it slightly
counter clockwise to bring it upright.
CAUTION: Continuing to turn the ORIFICE in any further will
cause damage to the POPPET SEAT, requiring its replace-
ment.
15. Place the DIAPHRAGM (3) inside the HOUSING (4) with the
raised Center facing up, and ensure that it seats flush at the Base
of the inner Threads of the HOUSING.
16. Place the COVER RING (1) on the FRONT COVER (2) and
thread it clockwise into the HOUSING (4), taking care to ensure
that it is correctly seated in the Threads. Hand tighten until
secure and ensure the FRONT COVER is properly aligned, with
the logo right side up (Fig. 19). Use the Front Cover Tool, if
necessary. DO NOT over tighten.
17. Secure the MOUTHPIECE (8) onto the HOUSING (4) with a new
TIE WRAP (35), positioning the Locking Tab of the TIE WRAP
towards the LP Hose.
NOTE: Oceanic's patented Orthodontic Mouthpieces are
designed to accommodate the natural overbite of the human
jaw. Ensure that it is properly positioned.
18. Lubricate the LP HOSE SWIVEL PACKING WASHER (33) and
insert it in the Inlet Coupling.
19. Install the LP HOSE ASSEMBLY (34) on to the Inlet of the VALVE
HOUSING (26), and tighten to a torque of 50 to 60 in/lbs with
an 11/16" open end wrench, while holding the Second Stage
secure.
