seal per following steps:
a. Lay unit down with outlet elbow up and remove hose.
!
CAUTION
Before proceeding with removal of seal and retaining
ring, make certain eyes are protected with proper safety
glasses. Retaining ring can pop out during removal and fly
several feet causing eye injury.
b. With a very small, flat bladed screwdriver
(approximately the size used for eye glass screws), pry
retaining ring out of groove in hose coupling. There is
a small cutout area in one end of the retaining ring for
this purpose. The ring can be prevented from flying out
of groove by placing thumb over a portion of inlet end
of hose during removal.
c. Remove retaining ring and the used metal bordered
hose seal. Discard both.
d. Place a new hose seal in end of hose.
e. Place a new retaining ring on hose coupling and press
it into retaining ring groove. The easiest way to do this
is start the side of the retaining ring opposite the gap
in the ring into groove and work ring into hose coupling
groove with both thumbnails.
f. Recheck the new hose seal to make certain it has not
been ruptured during installation.
g. Reinstall hose on extinguisher.
6. Place the funnel (Part No. 699) in the fill opening and fill
the extinguisher to the rated capacity with only the type of
ANSUL dry chemical specified on the nameplate.
7. Clean the fill opening threads and the gasket seating
surface of the shell. If pressure vents are cut in the
threads, be sure they are clean and unobstructed.
