CAUTION
DO NOT tolerate any leaks. Leaks can
result in corrosion and eventual
catastrophic vessel failure.
Replacing Elements (contd...)
6. Check that the spiral retaining ring is fully seated
in the groove. If it is not, remove and check for
foreign material that is causing the spiral ring not
to sit into the groove.
When all the elements are fully inserted into the
vessel, install the upstream head with the adapter
fitted if required, as described in paragraphs 4
through 6 on page 5 & 6.
11.Reconnect piping to vessel as described in Remaking
Pipe Connection to Eng Plug on page 10.
Retaining ring seated in the grooove
7. Lubricate element seals sparingly with the element
manufacturers recommended lubricant or with
glycerine.
12.Pressurize the vessel. Inspect for leaks at connections
to the vessel and all around the vessel itself. If any
leaks occur, release pressure from the vessel and
tighten the fittings as necessary. Then pressurize
vessel and check for leaks again.
8. Insert each element with the brine seal (typically a
U-cup seat) installed on the upstream end with its
lip facing upstream.
CAUTION
System malfunctions and element damage
may result if elements are
installed in the wrong direction.
9. Install the interconnectors between multiple elements
as each succeeding element is installed.
NOTE
On some systems it may be easier to install
the piping connections before the head
is installed.
If so, please proceed with Steps 10 & 11.
10.Push each element downstream into the shell as it is
installed until the element is fully engaged with the
downstream head. If the elements are hard to push,
make sure the brine seal is properly installed and you
are pushing from the upstream end.
