SRI hydrogen generator
7) Examine the oldPEM
for clues as towhy it may
have failed.
8) The newPEM is avail-
able fromSRI under part#
8690-0151 for the50ml/min
H2 genand8690-0152 for
the25ml/minmodel. The
newPEM is crystal clear and
comes inaplastic bag. It is
easy to think thebag is
empty because thePEM is
clear.
9) Soak the newPEM in
cleanwater prior to installa-

hydroscopic ( absorbswater )
andwill expand slightly as it
is soaked. Soak thePEM for
aminute or two.
