Contamination Removal
Metal oxidation products and mineral
deposits can interfere with vessel
disassembly. Remove all foreign matter
from both ends off vessel as follows:

brush or suitable abrasive (such as
medium-grade ScotchBrite
TM
).
Cleaning inside the vessel
2. Flush away loosened deposits with clean
water.

Disconnect Permeate Piping -
1. Disconnect permeate piping as required
at nearest convenient joint, being careful
not to place undue stress on the threaded
connections of the plastic permeate
port(s).
Remove the Retaining Ring from the
groove –
1. Lift the tabbed end of the retaining ring up
out of the stainless-steel groove in the
shell and then away from the head so that
it rests in the end margin of the vessel. This
is best accomplished by using CodeLine.
Removal Tool, part number 50303, which is
available from your supplier.
This can also be accomplished using a
screwdriver and a pair of pliers if the tool is not
readily available.
With the removal tool the retaining ring can
be lifted upward by simply rotating the tool
counterclockwise after inserting it over the
tab on the retaining ring. (Use the smaller
hole). Hold the tool flat against the end
margin and parallel to the vessel bore. It is
them possible to pull the end of the retaining
ring straight out. The retaining ring snap
back into the groove if this alignment is not
closely adhered to. If the retaining ring is
difficult to remove, try soaking with a release
agent such as LPS
TM
or WD40
TM
, being
careful to avoid any contamination of a
membrane element.
Retaining Ring Removal Tool
When using screwdriver and pliers, pry the
tabbed end of the retaining ring out of the
stainless-steel groove with the tip of the
screwdriver. Once the end of the retaining
ring is clear of the groove, grab the tab with
the pliers and pull towards the end of the
vessel until the end of the ring is resting in
the end margin of the shell.
2. Remove the 4” retaining ring from the
stainless groove in the shell by rotating
your finger behind the ring as it
continues to exit the groove.
