21. Remove the poppet seat(14) from the poppet(15) with the use of
a dental pick. (Fig. 7) Discard, and DO NOT attempt to reuse.
22. Inspect the overall condition of the housing(4) to ensure it is
free of any stress cracks or other distortions, and that the outer
threads are in good condition. Discard if distortion is found.
23. Using a soft probe, inspect the condition of the exhaust valve
diaphragm(6) to ensure that it is supple and free of any tears or
corrosion, and that it seals completely around the seating surface
of the housing. Examine the exhaust tee cover(5) to ensure that
it is securely fastened onto the housing.
NOTE: Provided that the exhaust valve diaphragm(6) is in
good condition and the exhaust tee cover(5) is intact, further
disassembly is not necessary. The housing may be cleaned
with these parts assembled, as one part. (Refer to the clean-
ing section of this manual.)
24. If further disassembly is needed, either to replace the diaphragm
or replace the exhaust tee cover, remove the exhaust tee cap
screws(7) with a 3/32" hex key. Remove the exhaust tee cover(5)
by lifting the bottom portion. The top portion of the cover acts
similar to a hinge (Fig. 8).
25. The exhaust valve diaphragm(6) may now be removed by grasp-
ing it at the flange and pulling it straight out, snipping the retainer
stem if necessary. Discard.
REASSEMBLY PROCEDURE
NOTE: Prior to reassembly, it is necessary to inspect all
parts, both new and those that are being reused. Check
to ensure that o-rings are clean and supple, and that every
part and component has been thoroughly cleaned and dried.
WARNING: Use only genuine Oceanic parts, subassemblies,
and components whenever assembling Oceanic products.
DO NOT attempt to substitute an Oceanic part with another
manufacturer’s, regardless of any similarity in shape, size,
or appearance. Doing so may render the product unsafe,
and could result in serious injury or death of the user.
1. Replace the exhaust valve diaphragm(6), if removed, into the
housing(4) by gently pulling the retainer stem through the hous-
ing(4) until the retaining flange is inside the housing and properly
seated. (Fig. 9)
