Opening the Vessel
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 ,ay 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
ful to avoid any contamination of a membrane
element.
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.
