Inspect the diaphragm (Item 21) and
exhaust valve (Item 20) for perforations or
cracks, especially along the edge and on the
"spider" where the exhaust valve attaches.
Replace if any are found.
Fit diaphragm (with exhaust valve installed)
on case, being sure the edge of the
diaphragm is in place on the case.
Place end cover over diaphragm and secure
with locking ring (Item 18)
SECTION 4 - QUICK DISCONNECT FITTING
The regulator may be fitted with one of several
similar types of QD coupling.
In all cases it is essential that the sleeve must
slide up to the shoulder of circlip when fitted
on the nipple. If the sleeve does not slide com-
pletely up to the shoulder when pushed into
place, it is possible for accidental disconnection
to occur.
