CAUTION: It is important that 3 Threads of the POPPET (6)
Shaft are adjusted outside the LOCK NUT (12). The LEVER
ARM (9) may otherwise become caught on the end of the
POPPET Shaft, resulting in an uncontrolled free flow.
8. Lubricate and install the COUPLING O-RING (4) onto the INLET
COUPLING (3). Install the COUPLING into the Inlet Tube of the
HOUSING (8) with the Smaller Opening facing in. Turn clock-
wise using a 3/4" open end wrench to a torque of 110 in/lbs (Fig.
10).
9. Lubricate and install the ORIFICE O-RING (1) onto the ORIFICE
(2). Lubricate the Threads of the ORIFICE with a very light film
of lubricant and insert the ORIFICE into the INLET COUPLING
(3) with the Knife Edge of the ORIFICE facing in (Fig. 11).
CAUTION: Be careful to protect the delicate Knife Edge of
the ORIFICE as this is done.
10. Using a narrow shafted, slotted blade screwdriver, gently turn the
ORIFICE (2) clockwise into the INLET COUPLING (3) until the
Knife Edge is
barely contacting the POPPET SEAT (5). DO NOT
continue to turn the ORIFICE any further beyond this point, which
will cause the LEVER ARM (9) to drop. Doing so will also damage
the ORIFICE Seat requiring its replacement.
NOTE: For best sensitivity of touch during step 18, place
your finger gently on the LOCK NUT (12) while slowly truning
the ORIFICE (2). As soon as contact is made, you will feel the
LOCK NUT begin to turn. Hold the screwdriver by the shaft
rather than by the handle.
11. Place the DIAPHRAGM (15) inside the HOUSING (8) with the
raised Center facing up, and ensure that it seats flush at the base
of the Inner Threads. Place the FRONT COVER (16) directly
over the DIAPHRAGM and ensure that it seats flush.
12. Lightly lubricate the Threads of the COVER RING (17), then
install it by rotating it in a clockwise direction into the HOUSING
(8), taking care to ensure that the COVER RING is correctly
seated on the Threads. Hand tighten until secure.
13. Secure the MOUTHPIECE (18) onto the HOUSING (8) with a
new TIE WRAP (19), positioning the Locking Tab of the TIE
WRAP towards the Hose.
NOTE: Oceanic’s patented orthodontic Mouthpieces are
designed to accommodate the natural overbite of the human
jaw. Ensure that it is positioned correctly.
14. Lubricate and replace the O-ring inside the Second Stage
Coupling End of the LP Hose. Install the Hose onto the Second
Stage and tighten to a torque of 55 in/lbs with an 11/16" open
end wrench, while holding the Hex Portion of the INLET COU-
PLING (3) secure with either a 3/4" or 13/16" open end wrench.
